Possible Causes

Failed compressor relay on main PCB, Burnt relay contacts due to high current, Cracked solder joints on PCB, Control logic fault

How to Fix / Troubleshooting

Safety first: Unplug the wine cooler before accessing the control board. Mains voltage is present on relay contacts.

Steps to address E14:

  • Check basic operation: Confirm that the set temperature is lower than the actual temperature and that no other error codes are present.
  • Inspect main PCB: Remove the rear panel and locate the main control board. Look for a small relay labeled for compressor output.
  • Visual inspection: Check for burn marks, cracked solder joints, or melted plastic around the relay.
  • Board replacement: If the relay or PCB is visibly damaged, replace the entire main control PCB. Component-level repair is not recommended for non-professionals.

If you are not comfortable working with mains-voltage electronics, contact a Siemens service technician to replace the board.
