Ice maker shows E7 and stops; bin is empty but unit thinks the bin is full and will not start a new cycle.

Safety first: Disconnect power before working near moving parts.

• Check bin arm or lever: If your Hansa model uses a mechanical bin arm, ensure it moves freely and is not jammed by ice, packaging, or mineral buildup. Clean and free the arm.
• Clean optical sensors: For models with infrared sensors, locate the emitter and receiver on opposite sides of the bin opening. Wipe both lenses with a soft, dry cloth to remove frost or dirt.
• Verify alignment: Ensure the sensor brackets are not bent and that the sensors face each other directly. Adjust gently if misaligned.
• Inspect wiring: Trace the sensor harness back to the control board. Look for pinched, broken, or corroded wires. Repair or replace as needed.
• Sensor replacement: If cleaning and alignment do not clear the error, replace the bin full sensor assembly or mechanical switch with the correct Hansa part.
