Turn off the circuit breaker to the KitchenAid dishwasher. If your unit uses a power cord, unplug the power cord from the outlet in the adjacent cabinet.
Open the KitchenAid dishwasher door, and pull out the bottom dish rack. Grab the float with your fingers, and tip the float toward the rear of the dishwasher.
Lift the float up as you continue tipping toward the rear of the dishwasher until it disengages from the overfill assembly body.
Clean the area around the overfill assembly tube with a cloth. Inspect the center of the overfill assembly tube, and remove any debris from the tube with a cotton swab.
Debris such as food stuck inside the tube will cause the float not to rise properly.
Insert the stem of the new overfill protection float into the overfill assembly tube. Press the float down into the tube until you feel and hear it lock into the tube.
Lift the float with your fingers until it stops. Let go of the float.
The new float should fall without hesitation. Place the lower dish rack back into the dishwasher and close the door.
Turn on the circuit breaker or plug the power cord into the outlet.
Things You Will Need
- Cotton swab
- If the new float does not move freely, the overfill assembly switch might require replacement. Access to the switch is through the toe panel at the bottom of the unit. The assembly has two wires connecting to it and a nut that secures it to the bottom of the dishwasher.
