Display shows E14 and the internal light does not operate correctly or flickers.

Safety: Unplug the wine cooler before removing light covers or trims. LED drivers can carry high voltage.

E14 indicates a problem with the interior lighting circuit on some De Dietrich wine coolers.

• Check basic operation: Open and close the door to see if the light responds. Confirm that the light is not disabled via a control setting.
• Inspect the LED module: Remove the light cover inside the cabinet. Look for burn marks or water ingress on the LED strip or module.
• Check connections: Ensure the light connector is firmly attached and that wires are not damaged.
• Test with a known-good module: If available, temporarily connect a compatible LED module to see if the fault clears. If it does, replace the original module.
• Board driver fault: If the LED module is good but never receives power, the light driver circuit on the main PCB may be defective, requiring board replacement.
• Reassemble and test: After replacing the faulty component, restore power and verify stable light operation and that E14 is cleared.
