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 the E13 error clears with the light disconnected. If it does, the module is likely short-circuited.
• 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 the E13 error persists even with the light disconnected, the light driver circuit on the main control board may be damaged, requiring replacement.
