Could a failing Drain Pump Assembly cause the SAMSUNG WF45R6100 to have symptom: Not Draining Water?

The drain pump motor uses a permanent magnet rotor that can decouple from the impeller shaft over time, leading to a motor that hums but fails to move water. This assembly includes the housing and the motor, ensuring that any internal check-valve failures or housing cracks are also addressed. It is the primary mechanical component responsible for evacuating water prior to the high-speed spin transition.

Could a failing Drain Pump Motor cause the SAMSUNG WF45R6100 to have symptom: Not Draining Water?

If the plastic housing is intact, the individual motor unit is the specific electromechanical failure point. Internal copper windings can short-circuit or open-circuit after repeated thermal cycling, preventing the magnetic field required to rotate the impeller. Replacing the motor alone is a granular fix for a pump that has failed electrically.

Could a failing Water Level Pressure Sensor cause the SAMSUNG WF45R6100 to have symptom: Not Draining Water?

This sensor monitors the air pressure in the dome tube to determine water volume. If the sensor's internal diaphragm fails or the frequency output drifts, the control board may never receive the signal that water is present or needs to be evacuated, effectively stalling the drain sequence despite a functional pump.
