Could a failing Drain Pump Assembly cause the SAMSUNG WA50R5400 to have symptom: Not Draining?

The drain pump is responsible for creating the centrifugal force necessary to expel water from the tub. Over time, the internal seals can degrade, allowing water to enter the motor housing and cause a short or mechanical seizure. Replacing the entire assembly ensures the motor and impeller housing are both restored to factory performance.

Could a failing Drain Hose Assembly cause the SAMSUNG WA50R5400 to have symptom: Not Draining?

Internal blockages or kinks in the corrugated drain line can increase backpressure on the pump, preventing flow. If the pump is heard running but no water is exiting, a physical obstruction in this line is the primary secondary cause.

Could a failing Pressure Switch (Water Level Sensor) cause the SAMSUNG WA50R5400 to have symptom: Not Draining?

If the pressure switch fails to detect the reduction in water level or is stuck in the 'Full' position, the control board may cease the drainage sequence or fail to transition to the spin cycle. This sensor communicates the hydrostatic pressure from the tub to the main PCB.
