The Whirlpool WPW10567645 is an essential part of your dishwasher, specifically the circulation pump and motor assembly. This component controls the passage of water throughout your dishwasher throughout the wash cycle. The motor generates the necessary power to run the pump, which takes water from the dishwasher's sump region and propels it up through the arms that spray water. These spray arms then spread water throughout the dishwasher, cleaning your dishes. A properly operating pump and motor component is required to ensure that your dishwasher cleans effectively. Without it, your dishwasher may fail to fill, wash, drain, or even start. Additionally, a malfunctioning pump and motor assembly may cause leakage.
