E13 error code, interior light may not work or stays on, door alarm may sound incorrectly

Safety: Unplug the wine cooler before working on the light assembly.

• Inspect light module: Remove the light cover inside the cabinet. Look for signs of moisture, corrosion, or burnt LEDs.
• Disconnect light: Unplug the CELLA LED light module from its connector. Restore power briefly to see if E13 clears with the light disconnected. If it does, the module is likely shorted.
• Check wiring: Inspect the harness from the light to the main board for pinched or cut wires, especially near panel edges.
• Replace light module: Install a new LED light assembly, ensuring the gasket or seal is intact to prevent future moisture intrusion.
• Control board: If E13 persists even with the light disconnected, the light driver circuit on the main control board may be damaged and require replacement.
