Understanding the Problem
If your Samsung WA45N3050AW fills with water and runs through the wash but fails to drain or spin out the water, the washer will stop mid-cycle, leave clothes soaking wet, or display drain-related error codes (commonly 5C/SE or related errors). This problem is usually caused by a drainage or lid/interlock issue — the machine either can't remove the water or it detects the lid is open and refuses to engage the spin cycle. Typical root causes include a clogged or failed drain pump, a kinked/blocked drain hose, a faulty lid switch/lid lock that prevents the motor from engaging for spin, or an electronic control/PCB issue. Mechanical problems such as a seized pump impeller (from debris like coins or fabric fibers), or an unbalanced load that prevents spin, can also produce the same symptoms. Start with the simple checks (hose/strain filter and error codes) before replacing major components.
Common Symptoms
Washer completes wash but won't drain or spin, water left in tub, washer pauses mid-cycle, washer displays drain or lid-related error code (e.g., 5C/SE), humming or no sound from pump during drain attempt, clothes come out dripping wet.
Common Causes
- Clogged or kinked drain hose or pump inlet (debris, coins, lint)
- Failed drain pump (electrical or mechanical failure)
- Faulty lid switch or lid lock (washer won't allow spin if lid detected open)
- Unbalanced load preventing spin or a fault on the control board wiring to pump/motor

Helpful Repair Tip
First remove standing water and look inside the inlet pump/filter area and drain hose for debris. Listen for the drain pump motor during a drain cycle — no noise often means a failed pump or lack of power to it. Use a multimeter to check continuity on the drain pump and lid switch before buying parts, and always verify part numbers against your washer's model/serial sticker.
Frequently Asked Questions
How do I tell if the drain pump or the lid switch is bad?
Start by removing visible water and checking the drain hose for kinks or blockages and the pump inlet for debris. Run a drain/spin cycle and listen: a working pump usually hums or runs; silence can indicate a failed pump or no power. Next, open and close the lid during a spin attempt — if the washer immediately engages spin when you manipulate the lid, the lid switch may be intermittent or failing. For a definitive check, disconnect power and use a multimeter to test continuity on the pump and the lid switch. Replace the part that shows no continuity or fails to run when supplied with the correct voltage (if you can safely test it).
Can I replace the drain pump or lid switch myself, and how much will it cost?
Yes, many DIYers can replace the drain pump or lid switch. First unplug the washer, turn off water, and drain any remaining water. Replacing the pump typically involves removing the access panel, disconnecting a few hose clamps and electrical connectors, and swapping the unit — 30–60 minutes for a competent DIYer. The lid switch is often accessed under the top panel and takes 15–30 minutes. Parts cost varies: drain pumps commonly range $40–$120, lid switches $15–$50. If you’re not comfortable with electrical testing or removing panels, hire a technician. Always verify replacement part numbers against the washer’s model and serial tag before ordering.
