The Whirlpool WPW10328226 Dishwasher Pump and Motor Assembly is a replacement component that circulates water to support proper cleaning performance in compatible dishwashers. It combines the pump and motor into a single assembly that operates by drawing water from the sump and directing it through the spray arms at the required pressure throughout the wash cycle. Installed beneath the dishwasher tub, it connects with the circulation system and electrical connections to regulate water movement during operation. Proper operation of this assembly supports consistent water distribution, assists in effective soil removal from dishes, and helps maintain reliable washing performance while reducing interruptions caused by a worn or malfunctioning pump and motor unit.
