Fundamental rules

Special difficulties in installing and connecting the dishwasher yourself, no. However, there are several nuances that may come in handy. That's the main thing you need to know, doing the work yourself.

  • Be sure to inspect the dishwasher after unpacking to make sure there is no damage.
  • A thin water supply hose is connected to the water pipe through a tee.
  • The drain hose is connected to sewage drains (most often to a siphon).
  • Install the dishwasher extremely exactly, twisting the legs.
  • Do not forget to have an outlet with a grounding contact to connect the dishwasher to the mains.

For a built-in dishwasher, you need to prepare a niche where it will fit, and fasten the machine with bolts or other fasteners. There are no other principal differences. Now let's describe the process in more detail.

Required Tools

To install yourself without any problems, you must always have the tools you need at hand. To install the dishwasher, you may need:

  • A sharp knife or cutter to cut the packaging film;
  • adjustable wrench to unscrew twist nuts;
  • wire snapping nippers;
  • level to properly install the dishwasher;
  • screwdriver;
  • drill.

This is the basic set, and it, in general, is useful for any work. If you install an additional outlet, you must take care of its availability. The same applies to the additional length of the hose, as well as the tee, filter and ball valve. Perhaps you need a hose.

Water connection

Regardless of which model you have, the installation of the dishwasher with your own hands begins with the preparation of a place for it. You should clearly identify where the outlet will be located, so that it would be convenient to turn on the machine, what the distance to the drain is, and where the water will come from.


Even before you put the dishwasher on its rightful place, you need to take care of the outlets for connecting the hoses. Between the hose that goes to the sink faucet and the water pipe, install a tee, to which you can easily connect the water supply hose.


Very good, if it will be equipped with a ball valve. Even if the machine with the system "akvastop the crane can come in handy during repair or temporary disconnection.

If you want the water to filter before it enters the machine, then you need to install an additional filter. Before the filter it is necessary to place the crane so that it can be closed at the right moment and independently, without calling the plumbers, clean the filter.

Providing drainage

The next stage of installing the dishwasher is to connect it to the sewerage lines. The easiest way is to connect the dishwasher to the siphon. To do this, use a siphon with an additional branch pipe. The nozzle is designed specifically for draining. The insert with a branch pipe can be purchased in addition to the already standing siphon. Installation of such a system is fairly simple, and you do not need additional knowledge about the sewage system. We must not forget that the hose should be placed in such a way that the water during the washing process could not flow into the drain by gravity.


If, for some reason, diversion into the siphon is not possible, the drainage system must prevent water from sucking or unpleasant odors from the sewage system.

For this purpose, the hose is fixed at a height of approximately m from the level of the sewer pipe to which it is connected. When installing the dishwasher yourself, remember that the maximum length of the plum hose should not exceed 5 m.

Power supply and securing

Since the dishwasher is an electrical appliance that is constantly in contact with water, it needs an outlet with grounding. Sometimes a separate branch is carried out from the shield and supplied with an automatic device designed for 16 A and RCD. It is possible to conduct electrical work with your own hands only if you have a certain experience. Otherwise, it is better to invite an electrician for this.

To prevent strong vibration and "jumps" of the dishwasher, it is necessary to install it exactly in accordance with the level. To do this, twist the legs. The built-in dishwasher must be additionally secured and the front panel installed, similarly fastening it.

In conclusion, we note that the installation of the smallest compact dishwashers is the simplest. The supply of cold water from them can be provided through a tap, and drained directly into the sink.
