Start off by turning the dishwasher’s electrical breaker off at the breaker box. Go to your breaker box and look for the breaker labeled “Dishwasher.” Turn it to “Off.”
Position the water and electrical cables on the floor. The water cable will be made of a copper material and the electrical line will look like any other power cable. Lay the two lines down on the floor.
Position your new Maytag dishwasher so it backs up to the dishwasher cutout in your kitchen. Take the water line and connect it to the water inlet on the back of the dishwasher. This inlet will be a valve on the top left side of the unit. Use a pair of pliers or channel locks to tighten the inlet nut to the water line.
Feed the electrical line through the electrical input on the bottom of the dishwasher. Connect the colored wires together and then secure them with wire nuts. For instance, connect the red wire from the electrical line to the red wire coming from the dishwasher.
Attach the drain line to your dishwasher. The drain line will be a threaded tube going to the drain line in your sink. Connect the drain line to the drain valve on your dishwasher located on the top right hand side of the unit.
Move the dishwasher into place and secure the dishwasher to the underside of your counter top with a drill and the fastening bracket on the top of the dishwasher.
Go back to your breaker box and turn the dishwasher breaker back on. Go to your dishwasher and turn it on to test it. Look for any leaks coming from the dishwasher and tighten any connections as needed.
