Possible Causes
How to Fix / Troubleshooting
Warning: Disconnect the appliance from mains before removing the control panel. Handle glass doors and trims carefully to avoid breakage.
E15 suggests a communication or hardware problem with the user interface on De Dietrich wine coolers.
- Inspect the fascia: Check for signs of condensation or liquid spills around the control panel area.
- Access the UI board: Remove the inner door trim or top panel (depending on model) to expose the touch panel and its ribbon cable.
- Check connections: Ensure the ribbon cable is fully inserted and locked at both the UI board and main PCB ends.
- Look for damage: Examine the ribbon for kinks, cracks, or corrosion on the contacts. Replace if damaged.
- Panel replacement: If connections are sound but buttons remain unresponsive and E15 persists, replace the complete user interface/touch panel assembly with the correct De Dietrich part.
- Re-test: Reassemble the fascia, restore power, and verify that all buttons respond and that E15 is cleared.
