How to Fix / Troubleshooting
Safety first: Unplug the washer before accessing internal components.
- 1. Check motor for shorts: Disconnect the motor and measure resistance between windings and to ground. Any short to chassis indicates a bad motor that must be replaced.
- 2. Inspect harness: Look for melted insulation or arcing marks along the motor wiring.
- 3. Examine PCB: Remove the main control module and inspect the motor drive area for burnt components. If damage is visible, replace the PCB.
- 4. Replace faulty parts: Install a new motor or PCB as required, ensuring correct Amica part numbers.
- 5. Test with light load: After reassembly, run a short cycle with a small load to confirm normal motor operation and that E51 does not recur.
