E7 error appears, unit may start but stops when ice reaches the sensor area, or may not detect ice at all.

Safety first: Unplug the ice maker before working near the evaporator or sensor assemblies.

Step-by-step:

• Locate the ice thickness sensor: On many G3 Ferrari models, this is a small metal probe or plastic paddle near the evaporator fingers that detects when ice reaches a certain size.
• Clean the probe: Use a soft cloth soaked in a 1:1 mixture of white vinegar and water to remove mineral deposits or slime. Rinse with a damp cloth and dry thoroughly.
• Check position: Ensure the probe or paddle is correctly aligned relative to the evaporator. It should not be bent away or touching the evaporator directly.
• Inspect wiring: Follow the sensor wires back to the control PCB. Check for damage and ensure the connector is firmly seated.
• Test operation: Reassemble, plug in, and run a cycle. Observe whether ice is harvested at the correct size and whether E7 reappears.

When to call a technician: If cleaning and repositioning do not resolve E7, the ice thickness sensor or control board may require replacement.
