SAMSUNG WF45R6100AW/US Error Not Draining

Drain Pump Motor

The drain pump utilizes a synchronous motor to drive a centrifugal impeller; if the internal seals fail, water ingress causes short-circuiting of the stator windings. Additionally, physical debris often bypasses the filter and wedges against the impeller, causing the magnetic rotor to strip or the motor to overheat and seize. Replacing the motor restores the mechanical torque required to move the water column against the head pressure of the standpipe.

Drain Pump Debris Filter

This filter is designed to capture lint and foreign objects before they reach the pump impeller; however, it can become completely occluded by 'scrud' (detergent and fabric softener buildup) or calcified debris. If the filter is cross-threaded or the gasket is compromised during manual cleaning, it can prevent proper suction, leading to a cavitation-like state where the pump cannot prime.

Water Level Pressure Switch

The machine relies on a diaphragm-based pressure sensor to determine if water is present in the tub via air pressure in a dedicated tube. If the tube is blocked or the sensor diaphragm loses elasticity, the control board receives an incorrect frequency signal, potentially failing to trigger the drain cycle even if the pump is mechanically sound.
