Dishwasher Installation Guide

Installing a dishwasher could have a few difficulties if you don’t have any technical experience. Similarly to all the installation and repair services, making one wrong step could prevent your dishwasher from performing properly. However, if you know exactly what you need to do, you will install the dishwasher without any problems! This guide will show you step by step how to install a dishwasher; with decent technical skills, anyone following this manual can install a dishwashing machine correctly.

Tools You Need for a Dishwasher Installation

  • Drill
  • Drill Bits
  • Hole Saw
  • Level
  • Screwdriver
  • Pliers
  • Wrench of an adjustable size
  • Tubing cutter
  • Safety glasses
  • Marking pencil
  • Water supply line
  • Compressor fitting
  • Wire nuts
  • Voltage tester

Check the Location and the Unit

  • Take the dishwashing machine out of the box.
  • Read the instruction of the manufacturer that refer to the location of the dishwasher’s drainage lines and power supply.
  • Find the power cord connection, drain outlet and inlet solenoid valve by removing the bottom access panel of the dishwasher.
  • Ensure your dishwashing machine will fit in your kitchen. The standard width of the dishwasher is 24’’ and the standard high of the dishwasher is 34’’. Before starting the installation, dry fit your dishwashing machine to make sure it will fit perfectly.
  • Pull out the dishwasher from the location, move the unit to the side to make enough space for the dishwasher service beneath the cabinet.


Disconnect the Power and Water Supply

Make a hole for the discharge and supply

If you didn’t have a dishwasher on the same location before, you need to cut a hole for the supply and discharge.

  • Use a hole saw and a power drill to cut a hole with bigger measurements than the ones of your dishwasher tubes’.

Hot Water

  • Install a new valve under your kitchen sink. Ideally, the new valve will have two outlets. You must connect one to your sink and another to your dishwasher.

Connect the Drain Line

  • Lay down the dishwasher so you can see the back of the appliance.
  • Check if all the connections are visible.
  • Take off the cap from the drain line connection.
  • If the water comes out, do not worry. Factories usually test the units before the shipping.
  • Connect the drain line to your dishwashing machine.
  • Tighten the drain line carefully to avoid future drainage issues.


Connect the Wires

Ensure the power is off.

  • Use the wire connectors to connect all the wires together.
  • Connect White to White, Black to Black, Ground (bare wire) to the grounding screw (it could also be a green wire) and tighten down with the wrench.
  • Connect the supply cord to the electrical outlet, previously installed under the sink.

Level the Dishwasher

  • Place the dishwashing machine under the countertop.
  • Adjust the height of the legs and level the countertop.
  • Use screws to secure your dishwashing machine to the countertop.

Turn on the Water and Power

  • Turn on the water supply. Return to the plumbing system under the sink and attach the drain line tightly. Inspect if there are any leaks.
  • Turn on the power supply at the breaker.
