Drain Pump Motor
The spin cycle is software-gated by the water level sensor (pressure transducer). If the drain pump motor fails to evacuate the water within a specific timeout period, the controller will not initiate high-speed rotation to prevent motor strain and suspension damage from the excessive mass of undrained water. This part replaces the drive motor of the pump assembly, which is the most common point of electrical and mechanical failure in the drainage system.
