Defrost or de‑ice heater error on models with heated evaporator or door frame.

Safety: Unplug the ice maker. Heater circuits operate at mains voltage and can be hazardous.

• Locate heater assembly: On applicable Fagor models, the heater may be attached to the evaporator plate or door frame to prevent icing.
• Check continuity: Disconnect heater leads and measure resistance across the element. An open circuit indicates a failed heater that must be replaced.
• Inspect thermal fuse: Some heaters include an inline thermal fuse. Test for continuity and replace if open.
• Examine wiring: Look for burnt insulation or loose connections along the heater circuit.

After replacing faulty components, restore power and monitor for normal de‑icing without reoccurring E18.
