For more than 50 years, Whirlpool has been manufacturing and marketing a wide range of dishwashers. But even the newest Whirlpool dishwasher model will eventually need to be replaced, and you can remove an old Whirlpool dishwasher so that you can replace it with a new one. Dishwashers have three main connections that need to be cut before they can be removed: water, electricity and drainage.
Turn off the power for the old Whirlpool dishwasher you are removing. This can be done by going to the main circuit breaker for your house and moving the switch that controls the circuit for the dishwasher to the "Off" position. Check that you've cut the power on the right circuit by powering on the dishwasher. If the dishwasher doesn't start, you've cut the right switch.
Locate the water supply valve for the dishwasher. This is likely to be at the nearest sink location. In a typical kitchen installation, for example, this will be located directly beneath the kitchen sink. Rotate the water supply knob to the right to turn off the water.
Place a towel on the floor under the water supply valve. Use an adjustable wrench to loosen the coupling on the water supply hose where it connects to the valve.
Locate the drain hose connection for the Whirlpool washer. In the typical kitchen set-up, this will be connected to the drain or garbage disposal under the kitchen sink. Loosen the hose clamp with a screwdriver and then pull the drain hose off the drain or disposal nipple.
Remove the kick panel located just underneath the dishwasher door. The screws holding this in place are usually positioned at the sides. You may also need to open the Whirlpool dishwasher door to remove any screws on the top of the kick panel. Pull the kick panel off the front of the appliance.
Locate the terminal connections where the dishwasher ties into your home electricity. These are typically behind a panel that needs to be removed before you can disconnect the wires from the terminals. Loosen the screws and then pull the wires off the terminals. Cut away any wire nuts or electrical tape as needed with the wire cutters.
Open the door on the Whirlpool dishwasher. Look underneath the counter and along the sides of the dishwasher for the brackets holding it in place. Use a screwdriver to remove the screws.
Slowly pull the old Whirlpool dishwasher out from its place under the counter.
