Display shows E9 and the internal humidity reading is missing or incorrect (on models with hygrometry).

Safety first: Unplug the EuroCave before accessing the control panel or sensor modules.

Some EuroCave wine cabinets include a humidity sensor. E9 indicates the controller cannot read this sensor.

• Step 1 – Confirm model features: Verify that your model actually has a humidity sensor; consult the user manual. If not, E9 may indicate a board configuration issue.
• Step 2 – Locate humidity sensor: It is often positioned inside the cabinet near the top or integrated into a small module on the side wall.
• Step 3 – Visual inspection: Check for heavy condensation, mold, or corrosion on the sensor. Ensure it is not blocked by bottles or liners.
• Step 4 – Check connections: Follow the sensor cable to the control board and reseat the connector. Look for broken or frayed wires.
• Step 5 – Replace sensor module: If the sensor is visibly damaged or tests faulty, replace it with the correct EuroCave humidity sensor module.
• Step 6 – Dry out interior: Wipe excess moisture from the cabinet and ensure the drain (if present) is clear to prevent future condensation damage.

Note: If E9 persists after sensor replacement, the control board may require replacement or reprogramming.
