How to Fix / Troubleshooting
Safety: Disconnect the appliance from mains before touching any electronic components.
E6 generally points to an internal fault in the main control board.
- Power cycle: Unplug the refrigerator for 10–15 minutes, then reconnect. If E6 reappears, continue.
- Check supply voltage: Ensure the wall outlet provides stable voltage within the specified range. Avoid using low-quality extension leads.
- Inspect PCB: Remove the control board cover (usually at the rear or top). Look for burnt tracks, swollen capacitors, or signs of moisture.
- Connector check: Reseat all connectors to the PCB, including sensor harnesses and compressor relay connections.
- Replace PCB: If visible damage is present or E6 persists, the Candy main control board must be replaced with the exact part number. This repair is best handled by a qualified technician due to mains voltage and configuration requirements.
