The Whirlpool WP35-6465 Washer Water Drain Pump removes used water from the washer tub during the drain and spin stages of the wash cycle. This pump operates by using an internal motor-driven impeller that moves water through the drain outlet and into the household drainage line. It is typically installed at the lower section of the washer cabinet, where it connects to the tub outlet hose and the external drain hose. During operation, the pump activates when the washer control system signals the drain phase, allowing water to exit the tub efficiently. By supporting consistent water removal, this component assists in proper cycle completion and helps prevent water buildup inside the washing system.
