Whirlpool manufactures a number of dishwasher models, from portable machines to fully integrated electronic appliances. These appliances use a spray of soapy water to power food debris off of your dirty dishes. A pump located at the bottom of the dishwasher then pumps out this water into your home's sewage system. These pumps can occasionally fail, leaving you without a working dishwasher. Replacing the drain pump on a Whirlpool dishwasher will take care of this problem.

Shut off the power to the Whirlpool dishwasher where you will be replacing the pump. In most installations, this must be done at the main circuit. Turn the breaker that controls the dishwasher to the "off" position.
Remove the toe and kick panels from the dishwasher. The toe panel is located at the very bottom of the dishwasher, next to the floor. There are usually two screws, one on each side, holding this in place. The kick panel, located just beneath the door, may have screws at the top and bottom, depending on the Whirlpool model. To remove the screws at the top, open the dishwasher door so you can access the screws. Pull the toe and kick panels from the dishwasher frame.
Detach the drain hose from the pump. The drain hose is connected to one side of the pump and secured with a hose clamp. Unscrew the hose clamp and pull the hose off the pump.
Detach the wiring harness from the pump. Look for the wiring running into one side of the pump. Pull the wires out by the plug at the end, never by the wires.
Unscrew the dishwasher pump from the body. Use a socket wrench to unscrew the bolts holding the pump in place. There are usually four or more bolts, depending on the model.
Pull the dishwasher pump out of the Whirlpool dishwasher from underneath. Insert the new pump into the dishwasher from below. Secure with the bolts.
Replace the wiring harness by plugging the socket back into the pump. Connect the drain hose and secure with the clamp.
Restore power to the dishwasher. Run a short load, such as the rinse cycle. Watch the pump and connections below and check for leaks while the cycle is running. If you see a leak, immediately kill the power for the dishwasher and tighten any bolts or hose clamps. Restore the power. Run the washer again and continue the process of tightening until there are no more leaks.
Replace the toe panel and kick panels. Secure with the screws.
