Safety first: Disconnect the appliance from mains before removing internal panels.

On dual-zone EuroCave models, E8 often indicates a problem with the temperature sensor in one of the zones.

Step 1 – Identify affected zone: Compare displayed temperatures and actual bottle temperature in each zone. The zone with unrealistic readings is likely the one with the faulty sensor.
Step 2 – Locate zone sensor: Inside the affected zone, find the small sensor cover or probe on the rear or side wall. It may be behind a small plastic grille.
Step 3 – Inspect and reseat: Remove the cover, check the sensor for damage, and ensure the cable is intact. Reseat the connector if accessible.
Step 4 – Test/replace sensor: With power off, measure the sensor resistance and compare to spec. Replace with the correct EuroCave zone NTC sensor if readings are abnormal.
Step 5 – Check harness routing: Ensure the sensor cable is not pinched by shelves or panels and is routed as originally installed.
Step 6 – Reassemble and test: Restore power and verify that E8 clears and the zone temperature stabilizes over several hours.
