What Does Error SE Mean?
The LG washing machine SE error indicates a malfunction in the motor speed sensor, specifically related to the Hall effect or position sensor. This error prevents the washer from detecting or controlling drum movement, often resulting in the machine stopping during the spin cycle or the drum failing to rotate. Users may notice unusual sounds during operation, and the error will persist until the underlying issue is resolved.
Common Symptoms:
- Washing machine stops during spin or will not enter a spin cycle
- Drum does not rotate despite attempts in various cycles
- Error appears consistently until root cause is resolved
Possible Causes
- Faulty Hall effect/position sensor (medium)
- Wiring or connection issues to motor/sensor (medium)
- Motor/drive assembly malfunction (medium)
How to Fix Error SE
DIY Fix Basic checks and resets
- Turn off and unplug the washer for 10–20 minutes to reset the internal electronics.
- Ensure the washer is unloaded or lightly loaded, then attempt a spin cycle.
- Check that the washer is level and there’s no physical obstruction to drum movement.
Technician Only Inspect and repair motor control and sensors
- Test and, if necessary, replace the Hall/position sensor responsible for drum speed detection.
- Inspect motor wiring harness and connectors for damage or loose connections; repair as needed.
- Check tacho generator, drive belt (if applicable), and motor functionality; replace faulty parts.
Parts needed: Hall effect/position sensor, motor wiring harness, drive belt (if present), motor/tacho generator assembly
- If the error persists after basic reset and level checks
- If you are not comfortable accessing internal motor or sensor components safely
- If wiring harness or motor tests indicate failure requiring part replacement
