Ice maker shows E11; evaporator temperature remains too high and no ice forms even though the compressor runs.

Safety first: Unplug the unit. Refrigeration system work must be performed by a certified technician.

• Basic airflow checks: Ensure the condenser coil is clean and the condenser fan is operating correctly. Poor heat rejection can mimic low refrigerant symptoms.
• Inspect for oil stains: Look around tubing joints, the evaporator, and condenser for oily residue indicating a refrigerant leak.
• Check evaporator frost pattern: With a technician present, observe the evaporator. A partial frost pattern or only at the inlet suggests low charge or restriction.
• Thermistor verification: Test the evaporator thermistor to rule out a sensor error causing false E11 codes.
• Call a professional: If a sealed system issue is suspected, contact an authorized Hansa service provider to locate leaks, evacuate, and recharge the system or replace the compressor as needed.
