Freezer shows E9 and may not cool; compressor may not run or may shut down quickly.

Safety: Unplug the freezer before cleaning or accessing the compressor area.

• 1. Check ventilation: Ensure there is adequate space around the freezer (especially at the rear and sides) as per Siemens installation instructions. Remove any obstructions.
• 2. Clean condenser coils: Remove the rear lower panel and vacuum dust from the condenser coils and surrounding area. Use a soft brush to avoid bending fins.
• 3. Inspect condenser fan (if fitted): On some Siemens no-frost freezers, a fan cools the condenser. Check that it spins freely and is not obstructed. Replace the fan motor if it does not run when the compressor is on.
• 4. Check compressor overload: Inspect the thermal overload protector on the compressor for signs of overheating or damage. Replace if it trips frequently despite good ventilation.
• 5. Power reset: After cleaning and checks, unplug for 10 minutes, then reconnect and monitor operation. E9 should clear if overheating is resolved.

Important: If E9 recurs and the compressor is extremely hot to the touch, there may be a sealed-system problem (e.g., high head pressure, partial blockage) that requires a refrigeration technician.
