Mainly dishwashers come in two varieties - a free standing unit with roller wheels and a counter-top unit for fixed placement. Whatever be the shape and service, this device saves time and energy, and is extremely efficient when employed. So, come with a little bit of basic electrical and plumbing skills that you have, let me show you a few lucid steps on installing a dishwasher in your kitchen.
Well, before we start, let's get to know the main steps that are involved in this process. It is the proper wiring, draining, and water supply. Proceed only after you complete the wiring and electrical connection work properly. Before that, turn off the main power supply around the place you plan to install and place a 3 x 3 foot piece of plywood on the floor to protect you against the risk of getting electrocuted.
1. Preparation
  • After finalizing the place, note that the cabinet door has a place for its opening. The standard width of a dishwasher is 24'' and height is 34'' in the US.
  • Make sure all the supplies are present around the area of installation, like the water supply, electrical outlet, drain system, and so on.
  • Drill three holes in the wall of the dishwasher for each aspect, water supply, drain pipes and electrical wiring.
2. Connecting the Drainpipe
  • Connect the drainpipe to the discharge pump and fix the drain hose to the top of the cabinet using a tape.
  • In most dishwashers, there is a knock-out plug for garbage disposals, which practically has to be removed before installation. So, as of now if you are installing one without a garbage disposal, then it will be needless to connect the drain hose to the inlet of the disposal.
3. Connecting the Water Supply Line
  • Hope you have a faucet with a dual outlet shutoff valve because one outlet has to connect to the hot water supply and the other one has to be attached to the dishwasher supply line.
  • This dual facility helps you to turn off the water supply without disturbing the sink faucet. So to install the valve, connect one to the faucet and the other to the dishwasher. Secure the water supply lines properly to avoid leakage and other problems.
4. Electrical Wiring
  • The main panel power supply has to be turned off before you proceed with any electrical wiring work.
  • Remove the lower plate of the dishwasher to get a clear access to the electrical unit of the device.
  • Use a nut driver to unscrew the cover bolt and next connect black wire to black, white to white and copper wire to ground screw.
  • Replace the cover bolt and align it the way it was.
You need to check for the dishwasher's working condition. Turn on the water supply, then the electric supply, check all the buttons on the device. Press the cancel button and drain all the water. If everything looks good, replace the lower base plates of the dishwasher carefully. Since this method requires a granite countertop, you will need to push it into the cabinet to secure the underside of the countertops with fasteners.
