How to Replace a Dishwasher – Part 6

How to Replace a Dishwasher – level the dishwasher, mount it to the counter top, connect the water supply and drain lines then wire the electrical connections.

This project is continued from Part 5.

Level the Dishwasher

Level the dishwasher by placing a carpenter’s level on the door and adjusting the front feet. Adjust the rear feet as needed to remove any wobble. Place the level on the bottom frame to check it’s level front-to-back and adjust only the rear feet.

Dishwasher Countertop Mounting Brackets

The dishwasher mounting brackets are highlighted in the yellow squares. The brackets are attached to the counter top with the two screws provided with the dishwasher.

Dishwasher Mounting Brackets

Set the dishwasher in the cabinet such that the sides of the tube (red arrows) is even with the cabinets face with an equal gap. The mounting brackets should be fully recessed under the counter top (yellow squares).

Careful! The dishwasher has a tendency to tip forward with the door open.

Connect the Water Supply Hose

Thread the water supply hose to the brass elbow until hand tight and tighten an extra 1/4 turn with a wrench. Do not use plumber’s tape or putty.

The connections will be checked for leaks later.

The dishwasher electrical connection is made inside the metal box on the right side of the dishwasher. Note the NM 14/2 house wiring lying on the floor.

The Frigidaire Gallery dishwasher has hot (black) and neutral (white) wires. Ground is made to the chassis via a ground screw. A pair of needle nose plies and wire strippers is very helpful.

Dishwasher Electrical Connection Wires

Twist the hot (black) and neutral (white) wires respectively together and fasten with wire nuts as shown. Form a small loop in the bare ground wire using the needle nose plies and fasten the ground wire to the frame with the green ground screw.
