Understanding the Problem
If your Samsung WF42H5200AP/A2 fills with water but either won't drain or won't complete the spin cycle, the most common problem is a failure in the drain system (pump, filter, hose) or a related sensor/control. Front-load washers typically attempt to drain before spinning; if water remains the machine will lock the door and stop the spin for safety. Symptoms can be caused by a simple clog (sock, lint, debris) in the pump or hose, a failed drain pump motor, a blocked drain filter, or less commonly, a faulty water-level (pressure) sensor or control board. Diagnosing the exact cause requires checking for obstructions, listening for pump operation during drain, and running diagnostic modes when available.
Common Symptoms
Washer fills but won’t drain or start the spin, clothes remain soaked, water visible in tub, error codes like 4C/5C/UE/dE, unusual humming from under the front panel, or visible leaks near the base.
Common Causes
- Clogged drain pump or pump filter (lint, coin, sock, debris)
- Blocked or kinked drain hose or incorrect drain height/installation
- Failed drain pump motor or damaged impeller
- Faulty water-level (pressure) sensor or faulty control board preventing drain command

Helpful Repair Tip
Put the washer into its diagnostic/drain mode (consult the owner's manual) and listen at the pump area: a working pump will hum and move water. If you hear humming but no water flow, the impeller may be jammed or the pump is weak — remove the drain filter and check for debris before replacing the pump.
Frequently Asked Questions
My washer shows an error code and won’t drain. Should I replace the pump?
Not immediately. First clear the drain filter and check the drain hose for kinks or blockages. Run the diagnostic/drain mode and listen — if the pump hums but no water moves, the impeller may be obstructed. If the pump makes no sound or runs intermittently, replacement is likely. Always verify with a visual inspection before ordering parts.
