How to Fix / Troubleshooting
Safety first: Unplug the wine cooler before removing the top or front control panel.
Er indicates a problem with the user interface or communication to the main control board.
- Step 1 – Power cycle: Disconnect power for 10–15 minutes, then reconnect. Sometimes this clears transient communication errors.
- Step 2 – Access control panel: Remove the trim screws and gently pull the control panel forward. Do not strain the ribbon cables.
- Step 3 – Reseat connectors: Carefully disconnect and reconnect the ribbon cable(s) between the display PCB and main board. Inspect for corrosion or bent pins.
- Step 4 – Inspect for moisture: Look for signs of condensation or liquid ingress around the control panel. Dry thoroughly and correct any source of moisture.
- Step 5 – Replace control panel PCB: If buttons or display segments are non-functional, replace the control panel PCB with the correct EuroCave part.
- Step 6 – Consider main board: If a known-good panel still shows Er, the main control board may be defective and require replacement.
