How to Fix / Troubleshooting
Safety first: Disconnect mains power before accessing the motor or control board.
- Observe behavior: If the drum only turns in one direction or jerks, note this for diagnosis.
- Check motor wiring:
- Access the motor and inspect the multi-pin connector.
- Ensure all wires are secure and not burnt.
- Control board relays: Inspect the main PCB for burnt or stuck relays controlling motor direction.
- Test motor (advanced): A technician can test motor windings for correct resistance; imbalance suggests motor replacement.
- If unsure: Due to the complexity of motor control, professional service is recommended for F27 faults.
Warning: Do not attempt to rewire the motor without a wiring diagram; incorrect connections can cause further damage.
