Error Code: 3E Difficulty: Hard
Problem: Motor tachometer/hall sensor signal error – no speed feedback to inverter
How to Fix 3E Error
- Unplug washer and remove rear panel.
- Locate hall sensor connector on motor stator (3-wire white connector near motor windings).
- Disconnect and inspect for corrosion or bent pins – clean with contact cleaner if needed.
- Measure resistance between pins 1-2 (should read
- 5-3kΩ), pins 2-3 (same value).
- Rotate drum manually 360° while monitoring resistance – should fluctuate smoothly without jumps.
- Replace hall sensor DC31-00138A if open circuit or erratic readings detected.
- If sensor tests good: check motor windings (U-V, V-W, W-U should read 5-15Ω balanced within 5%).
- Replace main PCB DC92-01543A if motor and sensor both test good but error returns immediately on restart.
Samsung Washer 3E Checks Before Replacing Parts
- Restart the washer and confirm the 3E 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 3E 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.
