How to Fix / Troubleshooting
Safety first: Unplug the washer before accessing the control panel or main PCB.
Step-by-step checks:
- Power reset: Disconnect power for at least 5 minutes to allow capacitors to discharge, then reconnect and try again. This can clear transient faults.
- Inspect control connections: Remove the top cover and control panel. Check all connectors on the main PCB and user interface board. Reseat them firmly.
- Check for visible damage: Look for burned components, cracked solder joints, or corrosion on the PCB. If present, the board should be replaced.
- Surge protection: If E14 occurred after a power outage or surge, consider using a surge protector after repair.
- Board replacement: If wiring and connectors are sound but E14 persists, replace the main control board with the correct Blomberg part. Programming may be required on some models.
