A dishwasher is a good purchase; it saves natural resources, time, and money. The quality of its operation and duration of operation depend on the correct installation of the unit. Connection to the water supply and sewerage is carried out in several successive stages, and a completely separate action is connecting to the electrical network. But, before connecting the dishwasher, you need to make the right choice of kitchen assistant.
Selection of dishwasher dimensions
Purchasing useful household appliances is a step towards improving the quality of life. In order to use equipment for a long time, it is worth understanding which one to purchase for your needs. When choosing, do not rely on the advice of friends and acquaintances; everyone’s needs are different, and there are many offers on the market. First, determine what type of machine your machine will be: free-standing equipment or built into a furniture kitchen set.
Now it’s the turn of another indicator: size. Sizes are classified into three types:
- narrow (overall dimensions: 0.45 x 0.6 x 0.85 m);
- full-size (overall dimensions: 0.6 × 0.6 x 0.85 m);
- compact (overall dimensions: 0.45 x 0.55 x 0.45 m).
The criterion for choosing the size is the volume of the room where the car will be parked and the number of members of your family. If a large number of dishes are washed in the house at one time, then you should choose a full-size machine, and if there are three people in the family, then compact or narrow models are suitable. When purchasing built-in appliances, give preference to proven brands, for example, Ikea. An important role in the choice is played by connecting the dishwasher to the water supply and sewerage system. Ikea is one of the leaders in terms of price indicators and ease of connection service.
Dishwasher Specifications
For household appliances, energy saving class, economical water consumption, and dishwashing class are important. To understand which car to take, pay attention to the abbreviation pasted on the front panel of the device; most often there are three letters there. The first letter indicates the class of dishwashing, the second letter refers to the class of the drying process and the last letter indicates the level of energy consumption. Best option: AAA or AAA+. The lowest quality indicator of all processes is indicated by the Latin letter G.
Washing programs
Modern technology is equipped with many useful functions, but sometimes you can find exotic ones. Therefore, it is important to choose functionality not by quantity, but by quality and demand for functions for your family. The minimum set of dishwasher procedures should include:
- standard dishwashing;
- intensive wash cycle;
- quick wash;
- automatic dishwashing process.
This number of programs usually covers all the needs of the family, but if there are special requests, then equipment manufacturers will always satisfy the consumer’s needs. You can choose a unit with ozonation, Internet access or washing with silver ions. If there are children in the family, then an important addition will be the “child lock” function, which will protect the baby’s health and your nerves.
After you have chosen a dishwashing machine, you will need to connect the dishwasher to the water supply and sewerage system. A photo of each stage will help you; it is also important to read the instructions included with the machine.
Tools and materials
Connecting a dishwasher to the water supply and sewer system with your own hands requires materials, tools and desire. You will need:
- FUM tape;
- adjustable water wrench;
- shut-off valves on the tee);
- siphon with fittings or additional elbow with outlet pipe;
- building level;
- inspiration and desire.
Before the dishwasher arrives in your home, determine where it will be installed. It should be located in close proximity to water supply pipes and sewerage pipes. The distance to them should not exceed one and a half meters. This is due to the operation of the pump built into the machine and the length of the pipes supplied with the device.
The standard room for a dishwasher is the kitchen. Kitchen units are most often equipped with niches for built-in appliances, otherwise you will have to redo some of the lower cabinets. If you are installing a stationary model of the device, then take care of the length of the entire kitchen; space is needed for the dishwasher.
Compact dishwasher models require less installation effort. How to connect a dishwasher to sewerage and water supply with a modest size of the unit itself? Quite simple: they are installed on the countertop, next to the sink. The water supply is carried out through an additional tee mounted on the mixer, and the water is drained into the sink. Larger dimensions of equipment require a fundamental approach.
Prerequisites
So, the question has arisen about how to connect the dishwasher to the sewer and water supply. The instructions included with the device provide many tips. Pay attention to what kind of water should enter the machine: hot or cold. Most modern dishwashers are connected to cold water.
When choosing a location for installation, make sure that the surface does not have slopes and the machine must stand on a completely horizontal surface.
If the appliances are built-in, you will need to make holes in the back wall of the furniture in the places where the water supply and drainage pipes will pass. Connecting to water supply and sewerage does not differ from standard steps for installing equipment. The only thing that needs to be coordinated is the size of the furniture niche with the size of the unit you are going to purchase.
Connecting a dishwasher to water supply and sewerage has several options, each of them has its own nuances that must be taken into account.
A few words about electricity
The machine is connected to a standard European socket with a voltage of 220 V. A condition for safe operation of the energy-intensive unit is a separate socket with grounding, if we are talking about a private house, or grounding, if the dishwasher is installed in an apartment building. Extension cords and tees are not acceptable for connecting to the network. Compliance with safety rules when installing electrical household appliances with water supply is the best condition for long-term operation of a dishwasher or washing machine and the safety of electrical networks throughout the house.
Connection to the drainage system via a siphon
How to connect a dishwasher to the sewer yourself? Photos of the process will help you. If you choose to resolve the issue yourself, then be patient and knowledgeable.
There are two ways to connect the machine to the sewer: through the sink siphon and directly into the water drain pipe.
Connecting via a siphon is convenient if the dishwasher is adjacent to the sink.
The installation process is as follows:
- The standard siphon is replaced with a model with an additional outlet pipe. There can be two of them: one is used for the dishwasher, the second for the washing machine. A simpler option is to supplement the existing siphon with another elbow with pipes; the number of additional drainage pipes varies at your discretion.
- A drainage hose is connected to the siphon (it is included with the machine); the distance to the drainage point should not exceed one and a half meters. If the distance is greater, the pump built into the machine will not cope with its functions and may break.
- Take into account the slope of the hose towards the siphon; if it is insufficient, the drain water and food debris will be drawn back into the machine, which will not only cause an unpleasant odor, poorly washed dishes, but also damage to the dishwasher.
Connection to sewer pipe
This method is considered the simplest, since connecting the drainage hose to the sewer takes two minutes. But there are some nuances, and if you do not take them into account, you will end up with a poor drainage system. Features of direct water drain:
- The level of the water drain point from the dishwasher should be located at least forty centimeters from the level of the machine itself. Compliance with this requirement ensures the proper quality of water drainage; with other indicators, wastewater can be returned to the machine.
- If there is no direct possibility of maintaining the height of the water drainage level, the pipe must be bent in the form of an inverted Latin letter U; it is advisable to secure the pipe configuration with a clamping plastic tape (but do not tighten it, but simply shape it). Fix the structure on the inside of the furniture or on the wall.
- When connecting two drainage systems (dishwasher and washing machine) into one siphon, install check valves at each drain point. In this case, wastewater will most likely remain in the sewer system, and not in expensive equipment.
Connection to water supply via mixer
Traditionally, water supply is carried out in two ways: through a sink mixer or by inserting directly into the water supply pipes. We will now consider the sequence of connecting to the mixer.
To extend the life of your dishwasher, a water filter would be a good additional equipment. To connect to the mixer, you need a fum tape, a tee tap, and a water supply shut-off hose, which is included with the machine. Installation sequence for metal-plastic water supply pipes:
- disassemble the connection of the cold water supply hose to the mixer from the plastic water supply pipe;
- attach a tee to this place, having previously wrapped the threaded connections with fum tape;
- connect the flexible hose of the sink mixer to the upper hole of the tee;
- connect the outlet pipe of the tee to a coarse water filter;
- Screw a ball valve to the outlet of the filter; it will be needed to instantly disconnect the machine from the water supply;
- Connect the water supply hose to the dishwasher to the shut-off valve.
Do not forget to wrap all threaded connections with fum tape.
Taking water from water supply pipes
How to connect a dishwasher to a water supply made from metal pipes? It is necessary to stock up on additional materials. In this case, you will need a crimp coupling, a water control valve, and a drill.
Stages of work:
- turn off the water supply;
- mount the crimp coupling on the metal pipe and secure it tightly with bolts;
- drill a hole in the front wall of the pipe directly through the coupling hole;
- screw a shut-off ball valve or water filter onto the threaded coupling outlet;
- if a filter is used, then shut-off valves are installed at the outlet of the filter;
- to prevent leaks, wrap fum tape around metal threaded connections;
- Connect the flexible water supply hose to the ball valve.
Installation check
Before finally installing the machine in a permanent place, it is necessary to check how firmly all the pipes are fastened and whether there are any leaks at the joints. To do this, run the machine for a test operation cycle. During the test run, determine how the water intake pump works, listen to the noise of the machine - there should be no extraneous sounds. The test operating mode involves the use of detergents.
When drawing water, check the connection between the pipe and the tee or ferrule.
When draining water, also carefully inspect the connection between the machine's drain pipe and the siphon or waste pipe.
If leaks are detected, stop the machine, drain the water and disassemble the loose connection, reassemble it, additionally using fum tape or other sealants suitable for your types of pipes.
Last stage of installation
The last step in installing your dishwasher is to secure it in place. If you have built-in appliances, then it is mounted inside a furniture box. When installing furniture sets, leveling the furniture in a horizontal position is a standard procedure, so you don’t have to worry about the position of the machine. If you have free-standing equipment, check the horizontal installation using Small errors can be eliminated by adjusting the legs of the machine. Every time you tighten the legs, check that the installation is level.
Installation yourself and professionally
Connecting the dishwasher to the water supply and sewerage can be entrusted to professionals. There are many companies offering equipment connection, but it is better to trust the advice of friends who have already used the services of any company and were satisfied with the result of the work. But, since installing and connecting household appliances is not such a difficult task, almost anyone can do it themselves.
The attitude towards household appliances for washing dishes is still quite critical. But many still decide to take such a step, so before purchasing it you need to clearly understand how to connect the dishwasher to the sewer and water supply.
But if we remember the not so distant past, a similar attitude existed towards other household appliances - automatic washing machines or food processors.
Today it is difficult to imagine an apartment or house without these attributes of modern life. A person quickly gets used to comfort and is reluctant to part with it.
The same process happens today with dishwashers. But unlike other types of household equipment, the dishwasher cannot be delivered home, after removing the packaging and immediately connecting it to an electrical outlet.
Functionally, the dishwasher is also a piece of plumbing equipment. with a complex control system filling.
Naturally, dishes cannot be washed without water, so they need to be connected to the water supply network and properly connected to the sewer system.
Connecting dishwashers to communications
Household appliances cannot work without water, drainage of used water and electricity. How to provide it with the necessary resources?
Watch the video
Connecting to the water supply, determining the installation location, necessary materials and tools
There are several ways to do this work. First one of them is developed and used when the installation of household appliances is carried out at the stage of building a house during major renovations in the premises.
Under these conditions, there are no restrictions on wall gating, which makes it possible to arrange hidden connections.
Second way used when installing a dishwasher in an already equipped kitchen with minimal changes to the interior.
Many owners of dishwashers strive to connect not only cold but also hot water to their unit. The reason for making this decision is the desire to reduce water heating costs. The position is clear, but its implementation must be approached very carefully.
Not all dishwasher control software is designed to handle mixed flows.
You should carefully study the operating instructions for a particular unit to find out whether it is intended for such a connection. The electronic hardware may simply not understand the signal and the device will not work in the desired mode.
Even if the possibility of such a connection is available and specified in technical documents, experienced people recommend abandoning it. There are several reasons for this:
- The quality of water from the hot water supply system leaves much to be desired.
- There may be cases where the hot water from the pipework is at a temperature higher than that permitted for use with this device. This is only at first glance insignificant - the control unit may not work correctly.
- Problems with water supply from a hot water supply system occur much more regularly than with cold water. And during the hot period, a month-long interruption in the operation of the hot water supply due to scheduled repairs is inevitable. Thus, long downtime of expensive equipment and washing dishes by hand are inevitable. An alternative is an urgent transition to operating a dishwashing machine from a cold water supply.
- The issue of saving resources is also controversial. Modern “A” class dishwashers for dishes consume energy very economically, and if the home is equipped with water consumption meters, then in the calculation they will be used according to the tariff for hot water.
It's up to you to decide, of course. but expert opinion is in favor of cold water.
The first way to connect the dishwasher to the water supply
The most obvious solution is to connect the dishwasher to the outlet to which the flexible hose from the faucet is connected. To do this, their length from the unit sales kit should be sufficient.
Watch the video
For such a connection you will need a through tee, a wrench of the appropriate size and a sealing winding for threaded connections.
In such a situation, it is preferable to use a manifold - this is a metal or plastic tube with 5 or 6 threaded outlets on the side. You can connect all the necessary devices to it one by one, and mute the free outputs, considering them backup.
Then you can connect new additional equipment at any time. In addition, since each outlet is equipped with a ball valve, you can temporarily turn off any device without affecting the functioning of the entire system.
The second way to connect dishwashers to the water supply
It is used in cases where the length of the hoses included in the sales kit is not enough to use the nearest water supply point. In this case, you need to use a water pipe.
Watch the video
The method consists of inserting a side branch tee into the existing pipe. The procedure is as follows:
- Turn off the cold water supply circuit by turning off the tap on the riser.
- Mark the cutting location on the pipeline.
- Cut a piece of pipe to the required size, leaving the possibility of placing a standard tee with a side outlet.
- Install the tee.
- Connect the machine hose to the side outlet.
Depending on the type of pipeline material, installation technology may be different. The easiest way is to make an insert on a metal-plastic pipe. For this, standard press fittings are used.
The main thing when performing this operation is the correct marking of the length of the cut section and accurate cutting perpendicular to the axis of the pipe. This is achieved by using a special tool designed for this operation.
It is somewhat more difficult to insert into a polypropylene water supply. . If your apartment has a water supply system made of this material, you most likely have a soldering iron on hand. And if you don’t have it, you don’t have to buy it at all. A soldering iron can be rented for a few days for a small fee.
However, soldering the insert into a finished water supply is not at all easy - the place of action is limited in space, and it is almost impossible to bring the connected ends together. , which are alternately soldered to the ends of the pipe being connected.
Using this method is the easiest way to connect the dishwasher to the water supply. The tee is installed on the pipe using a rubber seal, securely tightened with screws, after which a hole of the required diameter is drilled in the pipe wall.
But it is worth noting that such a connection is not reliable enough and leaks more often than other methods.
The third way to connect to the water supply
One of them is to use kitchen siphons equipped with special outlets for connecting drainage pipes of household equipment. This makes it possible to connect several units. In this case, it is better not to combine the draining operation in these units. But this is the user's concern.
The outlet pipe ends with a nozzle that ensures the tightness of the connection when the screw clamp is tightened.
This connection method is very reliable, answering all the possible problems listed above:
- the device of the siphon itself structurally ensures the formation of a water barrier that prevents the penetration of “odors” from the sewer;
- the requirement for the height of the sewage system for dishwashers is met, the upper bend is obtained by itself during installation;
- The drain outlet is not connected directly to the sewer pipe, but is connected through an opening in the sink for drainage, which prevents the siphon effect from occurring.
Watch the video
The proposed connection method is good for everyone, but it is not always possible to implement it. For example, if the drainage hole is located at a distance from the installation site of the sink or sink. In such a situation, you will have to arrange a drain for dishwashers directly into the sewer pipe.
Sewage connections - method two
Watch the video
Many dishwasher owners prefer not to deal directly with the sewer system, discharging waste water directly into the sink.
The main motive for this decision is the assertion that a car is needed only after a large feast, for example, receiving a large number of guests. In such cases, the unit is needed periodically. Probably, with this approach, it is necessary to think about whether such household appliances are needed at all.
The optimal diagram for connecting a dishwasher to the sewer may look like this.
When connecting the dishwasher drain directly to the sewer pipe, you need to install an adapter on it, which is an angled branch from the drain pipe.
Other options for connecting a dishwasher to the sewer, if they exist, can be considered exotic. The choice of connection method depends on the relative position of the unit and the drain point.
Both of the above options are workable and reliable if executed correctly and can easily be done with your own hands.
Connecting the dishwasher to the electrical outlet
Connection to the network must be made through 16 ampere differential circuit breakers, and the leakage current should not exceed 30 milliamps.
The dishwasher socket is located on the wall. The installation height is no higher than 90 centimeters from the floor, and it is necessary that it is not located behind the device, but on either side.
Checking correct installation and connection
The reason for checking is a trivial situation - the machine, turned on according to all the rules, does not work. To determine the cause, you need to perform a few simple steps:
- You need to make sure that the power is supplied to the dishwasher and its value does not deviate from the required one. It is necessary to make sure that the socket, plug and connecting wire are in good working order. Most dishwashers are connected directly to the network, so you need to make sure that voltage is present at the input contact of the machine.
- When controlling an outlet with a switch (automatic), it is necessary to check its functionality with a tester. To do this, you need to remove its cover and close the circuit with the probes of the device. If the device shows that the circuit is closed, the machine is operational. Otherwise, it must be replaced with a new one.
- You must make sure that the unit door is closed, otherwise the machine will not turn on. To do this, with the door open, you must manually press the locking device lever, and then press the ON button. If the car does not start, you need to replace the latch with a new one.
- You need to check the operation of the control buttons on the panel, making sure that they are all installed in the correct position.
- The dishwasher may not sit level on the floor. In this case, the automation can also block the start of work. It must be leveled using the adjusting screws in the legs on which it is installed.

If all the measures taken are not effective, you need to invite a specialist from the warranty workshop. It is not recommended to disassemble the machine yourself - the right to repair under warranty will be lost.
Typical mistakes when installing a dishwasher
Almost all household appliances used in the home involve the use of electricity and water. Therefore, it is a source of increased danger. For safe operation you must:
- When connecting a dishwasher, it is necessary to use the appropriate power automatic and RCD, or differential circuit breaker. You cannot use a modular machine, much less safety plugs.
- Installing the dishwasher close to the wall. In this case, the hoses may become deformed, the machine’s automation may malfunction, or the room may flood.
- The machine must be positioned strictly horizontally, the slope tolerance is no more than 2 degrees. The installation is adjusted by turning/turning the legs. In some models, the position of the rear supports is adjusted with a special screw facing the front side.
- Installing a power outlet under the machine. When flooded with water, such installation leads to a short circuit with unpredictable consequences.
- When extending the water supply hose, never cut the standard hose. In a number of models, a signal wire is installed inside it, which reacts to a rupture of the hose and you will lose this important protective function.
- Using flax tow to seal threaded joints can be dangerous if you don't know how to use it. Excessive amounts of this material can tear the thin plastic union nut due to the die swelling when wet. Use FUM tape.

When purchasing a dishwasher, they often try to sell us on the services of a professional who will install it. This is quite logical, since the master and the store need additional profit. But it is not at all necessary to spend money on these services, because installing and connecting a dishwasher with your own hands does not present any difficulties. You can verify this after reading our instructions.
In fact, the installation and connection process comes down to three relatively simple procedures:
- Electrical connection;
- Plumbing connection;
- Organization of drainage.
All work can be done with minimal labor costs, and the main difficulty will be integrating the dishwasher into a niche (for built-in models).
We are looking for a suitable place for installation
Installing a dishwasher begins with finding a suitable location. If you purchased a free-standing model, it can be installed anywhere. As for built-in devices, they are mounted in kitchen units. In both options you should make sure that water supply and sewerage are located near the equipment. If water can still be carried even into the bedroom, then problems may arise with a distant sewer system - there will be an additional load on the drain pump.
The easiest way is to connect to the electrical network, since it is much easier to connect wires somewhere than to mess with pipes. The main thing is to protect yourself from accidental electric shock - for this you need to follow safety rules. Once you have completed the installation process of your dishwasher, you can safely begin testing it.
When choosing a place to install a household dishwasher, make sure that there is no heating nearby - equipment does not like exposure to heat.
Installing a dishwasher under the countertop is a painstaking process. In fact, it begins even before purchasing the device, since you need measure the installation compartment and calculate its depth. Based on the obtained parameters, we select the appropriate dishwasher model. Depending on the width of the section, we can purchase a device with a width of 45 cm or 60 cm. You also need to focus on the depth of the furniture so that the equipment fits completely into the niche prepared for it.
How to install a dishwasher in furniture? For this purpose, special fasteners are used, which are equipped with all furniture sets, “tailored” for the installation of built-in household appliances. If the fastener is positioned somehow incorrectly, you can always reposition it. Installation steps:
- Checking the location of fasteners;
- Securing the dishwasher in a niche;
- Hanging the door.
After this, you can begin testing.
With a free-standing machine, everything is much simpler - you need to place it anywhere in the kitchen and connect it to the water supply, electricity and sewerage. Just in case, we adjust it to the level, making sure that the device is level and without distortions. There are no special vibrations characteristic of washing machines, but it is better to ensure correct installation.
It is also possible to install free-standing dishwashers under the countertop - to do this, disassemble the furniture section where the appliances will be placed (from here, interfering shelves are removed).
Connection to water supply
You already know how to install a dishwasher of one type or another. Now let's start making connections. First of all, let's take care of the water supply. There are four connection methods available for consumers to choose from:
- With tee insert;
- End connection;
- With installation of a collector;
- With installation of a repair clip (bandage).
The most common installation and connection scheme is through a tee. It should be purchased from your local plumbing supply store. It would be convenient if the tee had a built-in ball valve. The tee itself can be metal or plastic. If you will be cutting it into plastic pipes, you may need a special plastic welding tool.
In the case of metal-plastic pipes, you can get by with a metal tee, which is screwed directly onto the pipe using a wrench. As for the welding machine, it is cheaper to rent than to buy.
The final connection involves laying a separate pipe to the dishwasher. It is connected to the water supply with a tee without a tap, and the tap itself is installed at the end of the pipe. This scheme is used when the dishwasher is installed away from the water supply (for safety reasons, it is better to lay a pipe rather than extend the inlet hose - this way you will be protected from leaks).
Connecting to the water supply with the installation of a collector is necessary when a large number of consumers are connected to the water supply - this is a washing machine, dishwasher, taps and filters. The collector is designed to restore order and reduce the number of taps into the main pipe - imagine how many tees will need to be installed to connect 5-6 consumers. Therefore, it is easier to install one collector.
Installing a dishwasher using a repair clip is not the best option. This type of connection boils down to installing and securing a special tee-bandage to a metal pipe. After this, a hole is drilled in the pipe through which water will flow into the dishwasher. The thing is that the rigidity of the pipe decreases, as well there is a high probability of leaks and blockages at the insertion point.
Before you begin installing your dishwasher, be sure to turn off the water in the riser. There are also recommendations for installing a coarse filter in the water supply. As for connecting to a hot water pipe, this is not recommended due to the poor quality of water in hot water supply systems.
Connection to sewerage
Installing and connecting dishwasher water to the sewer is easier than to the water supply. But there are certain subtleties here too. The whole point is that we will need to protect the dishwasher from the so-called siphon effect, when the sewer tries to suck water from the dishwasher - this often leads to equipment failure. It is also necessary to prevent the penetration of luxurious sewer “aromas” into the working chamber of the machine.
There are two ways to connect a dishwasher to the sewer:
- With the installation of an “oblique” tee;
- With siphon installation.
The first method is not the most optimal, but in some cases it remains the only available option. For example, when installing your dishwasher away from the sink where a trap could be installed. It is not recommended to extend the drain hose to avoid additional stress on the drain pump. Then an “oblique” tee cuts into the nearest section of the sewer pipe.
After the tee has been installed, you need to connect a hose to it, raising and lowering the hose. This is necessary to create reliable protection against the penetration of sewer contents into the working chamber of the dishwasher. In addition, to prevent the siphon effect, it is necessary to install a special anti-siphon valve.
The second option is simpler, more effective and safer - it involves installing a siphon, which will prevent the siphon effect from occurring and prevent odors from the sewer from entering the dishwasher. Buy a suitable one from a plumbing store siphon with one or two pipes for connecting equipment and install it under the sink. Connect the hose to it and secure the connection with a metal clamp. At this point, the connection process can be considered complete.
The drain hose is connected to the siphon to form a loop, which is necessary to prevent sink water and sewer odors from entering the dishwasher. Therefore, installing a siphon is the best way to connect to the water supply.
Electrical connection
We have reached the final stage of installing and connecting the dishwasher - we just need to supply electricity to it. If there is already an outlet near the installation site, then this is simply wonderful, because all we have to do is just plug the plug into it. Please note that dishwashers use Euro plugs, so the old socket will need to be replaced.
Is the nearest outlet located at a great distance from the installation location of your washing machine? Then you need to install a new outlet near it, powering it from another outlet or from a nearby distribution box. Many specialists it is recommended to install an RCD circuit breaker in front of it. But it is not at all necessary to pull a separate wire from the switchboard, since the power of the dishwasher is less than 3 kW - there is no need for excesses here.
Once you have installed the outlet, plug the dishwasher into it, open the center faucet, open the ball valve and start testing. Don't forget to make sure there are no leaks. If there are leaks, tighten the nuts or rewind the fum tape. Now you can load the dishwasher with detergent, salt and rinse aid, place the dishes in it and start the washing program.
Be sure to note that connecting the dishwasher through electrical extension cords is not permitted.
As we can see, the installation process of a household dishwasher is extremely simple. If you have the right tools at home (wrench, Phillips screwdriver, hacksaw), then the whole process will take you a couple of hours at most. The price for installing a dishwasher starts from 1000-1500 rubles, depending on the region and the complexity of the work. Moreover, this price does not include the cost of additional materials (tees, taps, pipes, etc.). Imagine how much money you'll save by doing the installation yourself.
It takes a couple of hours to connect the dishwasher if you have everything you need. If you don’t know how to connect a dishwasher with your own hands, then detailed instructions, a list of materials and tools are in front of you.
Dishwasher Connection Tools
You will need:
- Sewer siphon for drain connection.
- A shut-off ball valve that will shut off the water in front of the dishwasher.
- Brass tee fitting with ¾ inch thread for water connection.
- Filter for rough purification of supplied water.
- PVC pipe or high-pressure hose for drainage (if a siphon is not included).
- Pliers, screwdriver, electrical tape, FUM waterproofing tape.
It is recommended to install a tee not made of steel or cast iron (they rust quickly), but of bronze or brass; the ball valve is made of metal-plastic or made of the same brass or bronze. This way you will ensure long-term maintenance-free operation of the components.
Dirty water is discharged into the sewer through a siphon, so it is better that it be universal - with several fittings so that it can be connected to the drain holes of other household appliances.
The siphon also traps unpleasant odors from the sewer, so don't skimp on it - it doesn't matter how much the kit costs, it's important that it lasts a long time. Be sure to check the siphon package so as not to have to go back and forth for the missing gasket. The filter for water purification is the same as in the water meter system.
Procedure for connecting the dishwasher
Dishwashing machines are desktop, built-in (compact) and stationary. Despite the difference in dimensions, the connection of all communications is carried out according to the general principle with minor differences.
How to connect a dishwasher of any type - stationary, compact or built-in:
- Decide on the location where the dishwasher will be installed. Most often this is the work area next to the kitchen sink.
- Choose where you will connect the unit to the electrical network. It is safer if a separate outlet with grounding is installed, but this mainly applies to powerful devices.
- When installing a separate socket, choose a wire with a cross-section of 2.5 mm 2 and protection in the form of a 16 A circuit breaker. The optimal reliable option is to add a 30 mA RCD (residual current device).
- Select a location to connect to cold water. But you may have a model with a hot water connection, so you will need to connect the dishwasher to hot water.
- The water is connected with a special high-pressure hose with a ¾-inch union nut. Therefore, a shut-off valve with a ¾-inch thread must be screwed into the tee.
- The dishwasher drain is connected to the internal sewer system, and it is better to organize the connection separately through a siphon tee (for example, on a kitchen sink drain).
Now about how to connect the dishwasher drain. Draining is the easiest thing to do. To do this, each kitchen siphon has a plug at the bottom that needs to be unscrewed, and the siphon must be screwed onto this thread, and a hose for draining dirty water from the dishwasher will be connected to it.
The standard drain hose is 1.5 meters long, and this should be enough. The siphon has a built-in valve to delay backflow and odors from the sewer, but another protective measure can be taken - secure the drain hose so that a small half-ring is formed below the siphon. This will be a kind of water valve.
Electrical connection
Not everyone knows how to properly connect a dishwasher to the network. The best option is a separate socket, separate cable, grounding and separate protection in the form of an RCD and a circuit breaker. But this is the rule for powerful units and work for professionals. We want to connect the device ourselves.
So, we connect the dishwasher ourselves. For a kitchen in which a compact machine, for example a Bosch, will be installed, the option of connecting to the nearest outlet is suitable. Moreover, the entire electrical network of the apartment is protected by not one, but two automatic circuit breakers on the landing - one before the meter, and one after it.
For a low-power sink, you can buy a grounded socket plug and make an extension cord yourself. This connection with grounding protects from the load on the home network, and the fact that all wiring wires are concreted into the walls protects them from overheating.
How to add water
About how to connect a bosch dishwasher or another model to water. The cold water supply requires tapping into the water supply system, and this does not necessarily involve welding. Simply install a tee where the water is connected to the cold tap in the kitchen, from which the hose is led to the dishwasher.
Threaded connections must be sealed with FUM tape (8-12 turns must be made). For a tight connection, only hand effort is required, without keys. Instead of FUM tape, you can use linen winding, tow or sealant.
Immediately screw the ball valve (valve) onto the tee and connect the cold water hose to it. If your dishwasher model can be connected to DHW, then the essence of the process does not change - the tee cuts into the DHW supply pipe.
Features of connecting a portable machine
A tabletop dishwasher is installed on the countertop; the drainage is usually organized in the simplest way - dirty water is drained directly into the sink. Water is supplied to the compact dishwasher in the same way as in stationary models, and power is supplied from a regular kitchen electrical outlet.
Standard dimensions of the built-in model: width 450-600 mm, unit depth – 550 mm, height – 820 mm. The built-in model is installed in two versions:
- In a specially designated place in the kitchen unit (like a washing machine or mini-refrigerator) under the countertop, taking into account the size of the future unit.
- As a separate cabinet, decorated to resemble kitchen furniture. For this purpose, special fronts for dishwashers are sold, from which you can choose a suitable decor.
The built-in dishwasher must be connected to water, sewerage and voltage in the same way as in the stationary version. And what model your dishwasher will be: built-in, portable or stationary - depends only on the size of the kitchen space and your desire.
Features of connecting a stationary machine
You can find out how to connect the dishwasher yourself from the instructions that came with the device. All technological processes described in the instructions are accompanied by pictures and marked to ensure compliance with the sequence of operations. Often not everything is clear from the pictures, so use our advice.
The instructions may not contain specifics of the process, how to connect the dishwasher to the sewer, drain and voltage specifically for your conditions, so you need to proceed from the actual dimensions of the unit and the location of communications. You may have to lengthen the drain hose or buy a different siphon.
Checking the operation of the dishwasher
Before starting for the first time, check:
- Correct connection to the electrical network. To do this, simply turn on the machine for a few seconds.
- Water supply to the unit and drainage. Check all hoses for kinks and all threaded connections for leaks.
- Check the degree of inclination of the drain hose - water ideally should not stagnate in the hose, unless you yourself have organized a special additional water plug to protect against unpleasant odors from the sewer.
Now, if everything is fine, seal all service holes in the walls, if any (may be necessary when laying a cable, drain hose or water supply) and put the kitchen in order.
How to install a dishwasher yourself (video)
Tips from the user on how to connect a dishwasher (video) - watch and remember. All connections when connecting the drain and water require only manual effort - no special keys are needed for this. A minimum of tools and physical effort - and your dishwasher will start working.
Even a housewife can handle connecting a dishwasher, and there is no need to call a specialist. Just follow the sequence of operations, ensure that you have all the materials and tools, and you will succeed.

Who doesn't dream of a dishwasher? It helps you quickly cope with the kitchen routine, and avoid the standard family dilemma: “who goes to wash the dishes?” If you are going to buy such a “helper”, you should think about how the dishwasher is installed. Today I will describe in detail the algorithm for these actions so that you can connect the unit yourself.
Selecting a location and purchasing components
One of the most pressing problems for installing kitchen appliances is small-sized kitchens. The dishwasher is no exception, most likely the opposite - it requires a little more effort, since it needs to be connected to both water and electricity.
Often, when ordering a complete kitchen, most projects also allocate space for a dishwasher. If there is no such place, then you can organize it yourself by choosing a model that is suitable for installation on a table or has a universal design.
In this case, you need to consider how to connect the drainage system, water supply and electricity, so calculate the dimensions and all options in advance.
Electrical connection
We all know the basic safety requirements when working with electrical appliances, and they fully apply to the installation of a dishwasher, with some nuances.
First of all, it is necessary to take into account the fact that the device should only be connected to a European socket, because it has good grounding. Standard sockets without grounding are absolutely not suitable for installation.
If it is not possible to provide grounding, grounding can be done by connecting the grounding wire to the neutral. Are you the owner of “Soviet” sockets? Then contact a professional to replace them.
They will be able to bring a new, grounded outlet to the required level (25-35 cm above the floor), as well as make an additional one with a tap through a circuit breaker. In the diagram you can see with your own eyes the recommended position of the electrical wiring and connection of the machine.
Selection of tools
Despite some complexity in installing the dishwasher, we only need two tools: a screwdriver and pliers. You also need to take a roll of any electrical tape with which you can wrap the threads before tightening.
As a consumable, it is worth buying waterproofing tape, which will provide waterproof connections; its price is low.
But you will need to spend money on a water system, and I recommend buying the following components:
- Brass or bronze tee, with ¾ inch thread. I strongly advise against buying silumin, as it has poor resistance to crystalline corrosion.. Because of this, it can simply disintegrate, forming a serious leak.
- Drain siphon with two or one fitting. A double fitting is necessary for those who do not have an automatic washing machine. You can connect two drains to it simultaneously, both a washing machine and a dishwasher. If you do not plan to install a “washing machine” in the kitchen, or already have a separate drain for it, buy a siphon with one fitting.
- Ball type shut-off valve. Suitable from any material except silumin.
- Coarse water filter. It is not required, but if you want your dishwasher to last for a long time, I recommend that you install it too. Poorly treated water can cause serious damage. There is the same problem in foreign countries, so the filter is one of the important elements.
- Additional metal-plastic henka. If the machine is installed far from the sink, and a standard hanka is not enough, then we purchase a new one of the required length.
This concludes the list of components, and we move on to the DIY installation process itself.
Installing a “helper” in the kitchen
I will describe all the stages in the necessary sequence. If you follow them, installing and connecting the dishwasher will not cause you any difficulties.
Drain installation
Despite the simplicity of the work, there are several conditions that must be met:
- The lower knee should be as deep as possible, and its bend should be shorter. This type of water log can be seen in the toilet and sink. It is extremely important for a dishwasher, because if the miasma drain is empty, everything will go into the closed space of the machine.
