Drain Pump Motor
The drain pump motor uses a permanent magnet synchronous design that is susceptible to seal degradation. When water penetrates the rotor chamber, it creates magnetic drag and electrical shorting, preventing the impeller from reaching the RPM necessary to overcome head pressure in the drain line. Replacing the motor restores the electromechanical torque required for fluid evacuation.

Water Level Pressure Switch
This component monitors tub pressure to determine water volume via a frequency signal sent to the main PCB. If the internal diaphragm fails or the sensor drifts out of calibration, the machine may incorrectly 'see' an empty tub and fail to energize the drain pump circuit despite the presence of water.

Drain Pump Filter Assembly
The filter housing contains a debris trap and a check valve designed to prevent backflow. If the housing threads are cross-threaded or the internal check valve becomes mechanically seized by calcification or foreign objects, the pump's impeller cannot create the vacuum necessary to pull water from the tub.
