How to Fix / Troubleshooting
Safety: Disconnect power before handling the control board.
- Power cycle: Unplug the cooler for at least 10 minutes to allow capacitors to discharge, then reconnect. If E9 persists, continue.
- Check supply voltage: Ensure the outlet provides stable voltage within the specified range. Avoid extension cords or multi-plugs.
- Inspect PCB: Remove the control board cover and look for burnt components or obvious damage.
- Factory reset (if supported): Some Candy models allow a reset via button combination (consult the user manual). Perform the reset and observe if the error clears.
- Replace PCB: If the error remains, the "Main control board (PCB)" is likely faulty or has corrupted memory. Replace it with the exact part number for your model.
