Possible Causes
How to Fix / Troubleshooting
Disconnect the wine cooler from power before inspection. E8 indicates a power or low-voltage issue detected by the control board.
- Check the outlet: Plug another appliance or a lamp into the same outlet to verify proper voltage. Avoid using extension cords or power strips.
- Inspect the power cord: Look for cuts, burns, or crushed sections. Ensure the plug fits tightly in the outlet.
- Access the main PCB: Remove the rear lower panel to expose the control board. Look for burnt components, bulging capacitors, or darkened areas on the board.
- Reseat connectors: Unplug and reconnect the main power connector and any low-voltage connectors on the PCB to ensure good contact.
- Surge protection: If the unit is in an area with frequent power surges, consider using a quality surge protector after repairs.
If visible damage is present on the PCB or E8 persists, the main control board likely needs replacement by a qualified technician.
