Error Code: SE Difficulty: Moderate
Problem: Alternative drain error code on specific Samsung models (WF45T series)
How to Fix SE Error
- Clear drain filter completely.
- Remove pump assembly by disconnecting wiring harness, loosening hose clamp at discharge port, and rotating pump counter-clockwise 1/4 turn to release from mounting bracket.
- Inspect impeller for hair/fiber wrapping around motor shaft – clean thoroughly with needle-nose pliers.
- Check pump housing for cracks near mounting points.
- Test impeller rotation resistance – should spin freely with moderate drag.
- Reinstall pump ensuring O-ring seal properly seated in groove.
- Replace drain pump DC34-00008A if impeller damaged or housing cracked.
Samsung Washer SE Checks Before Replacing Parts
- Restart the washer and confirm the SE message returns under the same condition instead of after a one-time interruption.
- Check the simple causes first: load balance, water supply, drain flow, door or lid closure, visible leaks, and power stability.
- Inspect accessible wiring connectors and moisture-prone areas before assuming the control board has failed.
- Use the complete Samsung washer model number from the door, lid, or rear tag before matching any pump, valve, sensor, suspension, lock, or board category.
- If the SE code points to a specific system, test that system directly before ordering replacement parts.
