Could a failing Drain Pump Motor cause the SAMSUNG WF42H5000AW/A2 to have symptom: Not Draining Water?

The drain pump motor is a synchronous magnetic motor responsible for driving the impeller that evacuates water. Over time, the internal seals can weep, allowing water to enter the motor windings and cause electrical shorting, or the impeller can become detached from the shaft, preventing the centrifugal force required for drainage. Replacing the motor restores the mechanical lift necessary to push water through the drain hose and into the standpipe.

Could a failing Drain Pump Assembly (Complete) cause the SAMSUNG WF42H5000AW/A2 to have symptom: Not Draining Water?

This assembly includes the pump motor, the housing, and the debris filter chamber. It is recommended if the primary housing has been cracked by freezing water or if foreign objects (like coins or bra wires) have physically scarred the interior volute, which reduces pumping efficiency via cavitation. Replacing the full assembly ensures all gaskets and filter seals are renewed simultaneously.

Could a failing Tub-to-Pump Bellows Hose cause the SAMSUNG WF42H5000AW/A2 to have symptom: Not Draining Water?

This heavy-duty rubber hose connects the bottom of the outer tub to the drain pump intake. In many cases, a 'no drain' symptom is caused by a 'slug' of debris or small clothing items (like socks) becoming wedged in the bellows, physically blocking water flow before it even reaches the pump. If the pump is heard humming but no water moves, a mechanical blockage in this conduit is a high-probability factor.
