Drain Pump Motor
The drain pump in this unit uses a synchronous motor that can develop play in the impeller shaft over time. This mechanical wear, combined with the machine's intentional pulsing drain logic, results in an audible chattering or 'knocking' noise as the impeller oscillates against its housing. Replacing the motor restores the magnetic torque required to maintain quiet operation during the drain cycle.
