How To Install A Built-In Dishwasher

Finally, you bought a dishwasher. But instead of being happy with the purchase, you try to understand how the installation of the built-in dishwasher should proceed.

The instruction helps in these matters, but it is the same for all models, so it is not always clear in what order to act. In the article, you will learn how to properly install the dishwasher on your own.


A built-in dishwasher will hide behind the external facade, pretending to be nothing.

According to dishwasherfaq, it is better to integrate such dishwashers into a new kitchen set, where there will be a place for it. It should not stand close to the walls. Be sure to leave a place for ventilation – at least 5 cm. The rear wall of the cabinet may be missing or have holes for hoses.

Installing a built-in dishwasher yourself is quite simple. Included are templates with markings for fastenings for hanging a decorative panel. If you have to build on furniture that is already in the kitchen, choose a place near utility system.

The ideal option is to the right or left of the sink. Free a suitable cabinet from the shelves, remove the door. The installation under the countertop is convenient if the machine is equipped with wheels, which are adjustable in height.

It is not advisable to place the dishwasher near ovens or radiators. Upon purchase, a guarantee is issued for the equipment, which is canceled if incorrectly install it. For example, do not use tees or extension cords.

Do not connect the dishwasher to a furnace outlet. The cord of the machine is quite short, so the outlet should be located at a height of 45 cm from the floor.

How to install a dishwashing machine: tools and parts 

Prepare everything you need so that the tools are at hand. You will need: 

  • a set of slotted and cross screwdrivers; 
  • wrench; 
  • pliers; 
  • drill with a set of nozzles; 
  • nippers; 
  • level; 
  • chisel; 
  • tape measure.

Stock up on additional accessories: 

  • syphon tube; 
  • outlet; 
  • globe valve; 
  • brass tee; 
  • teflon tape; 
  • differential breaker; 
  • clamps and gaskets.

Electricity supply 

If you do not have a special outlet, we recommend that you call a specialist for installation. He will gouge a whole in the wall and lay a triple copper wire, install a differential breaker and connect a moisture-proof outlet. Now you are ready for further actions.

Connection to water supply 

Connect the dishwasher to a source of cold water, as it is better in quality. Moreover, it is equipped with a heating element, which independently heats the water. Read the instructions carefully.

It is possible that your model is allowed to be connected to cold water only, and when connected to hot water, you may lose your warranty. We recommend additionally installing a coarse filter. It will provide protection from large debris, soften the water, so the scale will not settle on the heater. 


Putting a tee on the end of the cold water pipe; connect the inlet hose to one outlet, and the mixer to the other. If your tee is not equipped with a stopcock, install it immediately.

Wrap the joints/abut with Teflon tape. It will seal all joints. 


  • First of all, a syphon tube (or a U-bend) with two openings for drainage needs to be installed. One will be used to connect to a dishwasher, the other – to a washing machine. You can also replace the sink with a more compact version. 
  • Install the drain hose 60 cm from the floor. Attach it with clamps to the furniture. Before connecting the end of the hose to the syphon, bend it so that water flows out of the machine into the siphon.

Not enough hose length? It is best to just buy a new one of the needed length. So you will avoid the risk of a flood. Now you know how to do all the work yourself. 

  • Then just move the dishwasher closer to the cabinet (can be immediately installed in the cabinet, if it is more convenient). 
  • Connect the drain hose to the syphon. 
  • Reconnect the intake hose. 
  • Slide the dishwasher under the countertop. 
  • Use the screw-bolts to install the facade.

The work is over. The only thing left is to conduct a test run to verify the connection is correct.
