How to Fix / Troubleshooting
Safety first: Disconnect power before accessing control panels.
- Power reset: Unplug the Grundig washer-dryer for at least 5–10 minutes to allow capacitors to discharge. Reconnect and try again.
- Inspect control connections: Remove the top cover and control panel. Check all connectors between the main PCB and the user interface board. Reseat them firmly.
- Check for visible damage: Look for burnt components, corrosion, or moisture on the control board. If present, the PCB will likely need replacement.
- Stable power supply: Ensure the appliance is connected to a stable mains supply without extension leads that may cause voltage drops.
- Replace PCB if required: If E14 persists after reseating connectors and power reset, the main control board may need to be replaced and programmed with the correct Grundig firmware by a qualified technician.
