Drain Pump Motor
This synchronous motor drives the impeller that evacuates water. Mechanical failure occurs when the internal permanent magnet rotor loses its magnetic strength or the shaft bushings wear, preventing the motor from overcoming the head pressure of the water in the drain line. Replacing the motor restores the centrifugal force required to empty the tub within the timed software window.

Drain Pump Filter Assembly
The filter acts as a coin trap and lint collector before water enters the pump impeller. Over time, debris accumulation or a damaged gasket on the filter housing creates flow restrictions or air leaks that impede the suction required for drainage. A new filter ensures an airtight seal and unobstructed fluid path to the pump.

Water Level Pressure Sensor
The OE error is triggered if this sensor fails to communicate an 'empty' status to the control board. If the diaphragm inside the sensor becomes stuck or the air chamber is blocked by sediment, the board assumes the washer is still full of water and halts the cycle to prevent a flood. This part is critical for the logic sequence that clears the OE error.
