Could a failing Drain Pump Assembly cause the SAMSUNG WA50R5400AW/US to have symptom: Not Draining?

The drain pump is the primary mechanical actuator for water evacuation. On this specific model series, the pump motor often fails due to internal seal leakage or winding degradation, preventing the impeller from spinning under load. Replacing the entire housing and motor assembly ensures that any internal obstructions or cracked housing components are addressed simultaneously.

Could a failing Drain Pump Motor cause the SAMSUNG WA50R5400AW/US to have symptom: Not Draining?

If the plastic housing is intact, the failure is typically isolated to the electromagnetic motor. This component loses the ability to generate the necessary torque to move the water column against gravity. Forensic inspection often reveals scorched windings or a magnet that has decoupled from the shaft.

Could a failing Water Level Pressure Switch cause the SAMSUNG WA50R5400AW/US to have symptom: Not Draining?

The control board relies on this sensor to determine when to engage and disengage the pump. If the internal diaphragm fails or the air pressure tube is clogged with suds residue, the machine may not recognize that water is present, failing to initiate the drain sequence despite the pump being functional.
