E11 error; ice cubes are too thin or too thick and the unit cannot complete a normal cycle.

Safety first: Disconnect power and allow the evaporator to warm slightly before touching any metal surfaces.

• Locate the ice thickness probe: On many Weasy models, a metal or plastic probe hangs near the evaporator plate or grid and senses the ice slab thickness during harvest.
• Clean the probe: Use a soft cloth and warm vinegar solution to remove mineral deposits from the probe surface. Rinse with clean water and dry.
• Check adjustment: Some probes are adjustable via a screw or bracket. Refer to the service manual for the correct gap between the probe and evaporator. Adjust if the gap is clearly too large or too small.
• Inspect wiring: Ensure the probe wires are intact and firmly connected to the control board.
• Test function: If accessible, manually move the probe to simulate ice contact and check for continuity change with a multimeter.
• Replace the ice thickness sensor/probe assembly if cleaning and adjustment do not resolve E11 or if the switch does not change state when actuated.
