The Whirlpool WPW10197864 Washer Electronic Control is the washing machine. This circuit board collects and interprets signals from the washer's many components, including the water level sensor and temperature sensor, to manage the washing cycle. This determines how much water to put in the tub, how long to agitate the clothing, and the proper spin speed for each cycle. Essentially, it converts your knob movements and button presses into a set of actions for the washing machine to carry out. A defective control board can cause a range of issues, such as the washer failing to start, filling with too much or too little water, or going through cycles incorrectly. Replace a malfunctioning control board with a compatible WPW10197864 to recover your washer.
