Display shows E5 and the compressor or fans may not start or may shut down quickly.

Safety: Unplug the unit. The compressor and condenser can be very hot; allow them to cool before touching.

• Check ventilation: Ensure the Climadiff wine cooler has the required clearance at the rear and sides and that front or rear grilles are not blocked by dust or cabinetry.
• Clean condenser: Remove the rear panel and gently vacuum or brush dust from the condenser coil. A clogged condenser causes overheating.
• Inspect condenser fan: On compressor models with a fan, verify that the fan spins freely and is not obstructed. Replace the fan motor if it does not run when powered.
• Check thermal protector: The compressor overload/thermal protector (often clipped to the compressor body) can fail. With power disconnected, test continuity; replace if open when cool.
• Allow full cool-down: Let the compressor cool for at least 30–60 minutes, then restore power and observe operation.
• If E5 persists: The main PCB may be misreading compressor current or temperature. At this stage, professional diagnosis of the compressor and control board is recommended.
