How to Fix / Troubleshooting
Safety first: Unplug the unit before accessing control boards or wiring.
- Power reset: Leave the unit unplugged for at least 5 minutes to discharge capacitors, then plug back in and try a short cycle. Sometimes transient faults clear with a reset.
- Inspect wiring harness: Remove the top panel and rear panel as needed. Trace the harness from the main PCB to the motor or inverter module. Check for pinched, cut, or burned wires and reseat all connectors firmly.
- Check for moisture: Look for signs of water leaks onto the control boards. If moisture is present, locate and repair the leak (e.g., from hoses or dispenser) and allow boards to dry completely.
- Visual inspection of boards: With power disconnected, inspect the main PCB and inverter for burned components or bulging capacitors. Any visible damage usually requires board replacement.
- Call a technician: Communication errors often require specialized diagnostics and may involve replacing the main PCB or inverter module. Professional service is recommended.
