E14 is displayed; unit may freeze water but ice thickness is inconsistent or too thin to harvest.

Safety first: Unplug the ice maker before adjusting or cleaning the thickness probe.

• Locate thickness probe: The probe is usually a metal or plastic arm that contacts the ice slab on the evaporator plate.
• Clean the probe: Remove mineral scale with a soft cloth and a mixture of warm water and white vinegar. Do not use abrasive pads that can damage the surface.
• Check adjustment: Verify that the probe is set to the factory‑recommended distance from the evaporator plate. Adjust according to the service manual if necessary.
• Inspect wiring: Ensure the probe's wiring harness is intact and firmly connected to the control board.
• Replace if faulty: If cleaning and adjustment do not resolve E14 and ice thickness remains erratic, replace the ice thickness sensor/probe assembly.
