Display shows E18 and humidity inside the wine cooler may be abnormal (too high or too low).

Safety: Unplug the unit before accessing internal sensors.

Steps:

• 1. Locate humidity sensor: On models with humidity control, the sensor is often mounted on an interior wall or near the evaporator cover.
• 2. Inspect sensor: Check for visible corrosion, water damage, or broken wires.
• 3. Reseat connector: Disconnect and reconnect the sensor plug to ensure good contact.
• 4. Replace sensor: If E18 persists, replace the humidity sensor with the correct Electrolux part.

Note: If replacing the sensor does not clear the error, the main control board may be defective and should be serviced by a professional.
