Error Code: FL1 Difficulty: Moderate
Problem: Flash code: 1 blink pattern = door lock system fault (models without display)
How to Fix FL1 Error
- For models with LED blink patterns instead of display: Count blinks after power-on (1 blink = door lock fault).
- Ensure door fully closed until audible click.
- Inspect door gasket for obstructions preventing seal.
- Remove top panel and check door lock wiring harness for damage near hinge area.
- Test door lock solenoid resistance (300-600Ω normal).
- Manually activate lock mechanism through front panel access hole – should engage smoothly.
- Replace door lock assembly DC34-00028A if solenoid open-circuit or mechanism binding.
- Verify 120V AC present at lock connector during lock attempt using multimeter.
Samsung Washer FL1 Checks Before Replacing Parts
- Restart the washer and confirm the FL1 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 FL1 code points to a specific system, test that system directly before ordering replacement parts.
Still Not Working?
If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
