Whirlpool W10866121 Electronic Control Board for Dishwasher

The Whirlpool W10866121 Dishwasher Electronic Control Board serves as the central control unit for your Whirlpool dishwasher, managing its various functions. This circuit board processes signals from multiple components, such as the temperature sensor, water level sensor, and cycle selector. It interprets these signals and communicates commands to other parts of the dishwasher, regulating functions like water fill levels, wash cycle times, and the operation of the heating element. Issues with the control board may lead to problems such as irregular wash cycles, insufficient cleaning, or failure to start or drain. Replacing a malfunctioning control board with the W10866121 restores the dishwasher's functionality.
