The home or residential dishwasher is literally part of the furniture for the vast majority of households. Unlike other common appliances, however, the dishwasher requires a little more attention when installing it.

In some cases, using a plumber may be required. In any case, a methodical installation of the dishwasher ensures that it works well for years to come.


The dishwasher is to be embedded under the kitchen counter, and usually, space is provided for this purpose. If this is not the case, you should be aware that a standard dishwasher is 35 inches high by 24 inches wide by 24 inches deep and that there should be some space at the back for the pipes, the insulation membrane and the positional fit (possible thanks to the unscrewable front legs).

The dishwasher can also rest on an anti-vibration mat, depending on the floor’s flatness and composition. Of course, it is only after all the other steps have been completed correctly that the recess must be done.

Note that installing a dishwasher in a location away from the water and wastewater supply lines may require a plumber and electrician’s work.

Another tip: in the case of a replacement device, it is always better to use new pipes and fittings even if the old ones still look good. Finally, make sure you have the right tools on hand, such as a multi-head screwdriver, a nut-turner, a socket wrench, pliers, a tube cutter, a wrench, a measuring tape, a drill and a boiler.


The actual installation of the dishwasher has three steps:

1- connecting the water supply;

2- the connection for evacuation;

3- electrical connection.

Not all parts required for these connections are necessarily in the packaging of the device. We are talking about screws, clamp collars, drain hoses, mouldings, hoods, white ribbon (plumbing), hot water pipes, fittings, etc.

The connection must be made to a hot water pipe. If the location already has a free power faucet, plugging in is easy. Connect the tip of the braided hose to the water inbound faucet.

Screw the fitting completely after taking care to insert the seal. Open the valve to validate. It is advisable to coat the tap fillets with silicone grease or wrap a plumbing strip in them. You can use an “autoperceur” faucet or cut and complete the pipes in the absence of a free faucet.

In both cases, it is preferable to entrust the task to a plumber.

The connection for evacuation is usually simple. Attach the dishwasher drain hose to the sewage pipe, specifically at the side entrance of its PVC back-up fitting (which is already in it). Make it sealed with a clamp collar. If this type of fitting is not present, again, it is better to call a plumber.

Connecting the dishwasher to the power supply involves a floor socket and a circuit breaker. The residence’s wiring must arrive at the back of the dishwasher junction box via an anti-traction ring. Distinguish the three wires from the dishwasher (white, black, green) with bare ends.

Use approved and good-sized connection caps to join the wires (white with white, black with black and green with a wire). Screw the lid of the junction box. Avoid incorporating an electric extension cord.
