Drain Pump Motor
The synchronous motor in this unit utilizes a permanent magnet rotor that is prone to internal seal failure. When water enters the rotor chamber, it creates magnetic drag and physical resistance that prevents the motor from reaching its required synchronous speed. Replacing the motor component restores the torque necessary to evacuate the drum.

Drain Pump Assembly
Debris such as coins or hardware can damage the internal volute of the pump housing or the integrated check valve. If the housing is scarred or the mounting tabs are fatigued, replacing only the motor may lead to premature failure or leaks. This complete assembly includes the housing and motor to ensure a total hydraulic seal.

Drain Pump Filter
While often just requiring cleaning, the filter can become cross-threaded or the O-ring can degrade, leading to air-leaks that cause the pump to lose its prime. If the filter mesh is physically compromised, it allows debris to strike the pump impeller, leading to mechanical failure. A new filter ensures the hydraulic circuit remains closed and debris-free.
