Whirlpool Dishwasher Installation Instructions

Updated February 21, 2017

Installing a dishwasher requires a basic knowledge of woodworking, plumbing and electrical work. There must be an open section of kitchen cabinets, and the unit must be connected to water and an electrical socket. Installation into new construction is easier because you, or your architect or designer will have designated a space for the unit. Installation into older construction that previously lacked a dishwasher is more difficult, but still doable.

Choose a location for the unit, preferably near the kitchen sink for easy access to the plumbing. Check the dimensions of your particular Whirlpool dishwasher unit and make sure there is enough space in the chosen location. Cut a 3-inch hole in the cabinet between the sink and dishwasher, 2 inches away from the wall and 3 inches away from the floor.

Connect the hot water supply line to the dishwasher fill valve. Wrap the male connector with plumber's tape, and screw the male and female ends of the supply line together. Hand-tighten the connector, then tighten it a quarter turn with an adjustable wrench.

Run the dishwasher cord and water supply line through the channels beneath the dishwasher. Run the drain tube from the dishwasher through the hole in the cabinet between the dishwasher and sink. Plug the unit in and push it back into place.

Insert the dishwasher drain tube into the sink drain inlet attached to the sink drain pipe. Secure the drain clamp around the pipe.

Screw the dishwasher to the cabinets. You will find brackets on top of the unit. Secure the brackets to the underside of the cabinets with screws.

Turn on the empty unit and check for any leaks. If you find any, tighten the plumbing connections.
