Possible Causes
Faulty motor relay on PCB, Damaged motor winding for one direction, Wiring fault to motor, Software/logic error
How to Fix / Troubleshooting
Safety: Disconnect power before working on the motor or PCB.
- Observe behavior: Start a wash cycle and note if the drum attempts to turn in both directions before the error appears (only test with panels fitted and safely).
- Motor tests: Remove and test the motor windings for continuity and equal resistance. A failed winding can prevent rotation in one direction.
- Harness inspection: Check the motor harness for broken conductors that might affect one direction only.
- PCB relay check: Inspect the PCB for burnt or stuck motor relays. This requires advanced skills and is usually done by a technician.
- Replace faulty parts: Replace the motor if windings are defective. If the motor is good, the PCB (with relays) may need replacement.
