How to replace Overfill Actuator Arm on your Whirlpool Dishwasher
Step-by-Step instructions on how to replace the Overfill Actuator Arm on a Whirlpool dishwasher. The Overfill Actuator Arm is part of the dishwasher’s float assembly. The float raises and lowers with the water level of the dishwasher. The float triggers the float switch if the dishwasher overfills to stop the dishwasher from overflowing with water. If any part of the float assembly fails the dishwasher may not properly sense the water level in the dishwasher which can cause the dishwasher to not fill with water properly.
