E07 error appears; ice cubes are very small, hollow, or production is slow; unit may run continuously.

Safety: Unplug the appliance. Refrigerant system repairs must be carried out by a certified refrigeration technician.

• Check evaporator frost pattern: With the cover removed (if accessible), observe the evaporator during operation. A partial frost pattern or only a small section icing indicates a possible refrigerant issue.
• Inspect evaporator sensor: Locate the evaporator NTC sensor clipped to the evaporator tubing or plate. Check for dislodged or damaged sensor. Ensure it is firmly attached and not covered in heavy ice.
• Test sensor resistance: With power off, disconnect the sensor and measure resistance at room temperature. Compare with Indesit specifications. Replace the sensor if readings are out of range.
• Look for oil stains: Oil marks on joints or tubing can indicate a refrigerant leak. Do not attempt to braze or recharge unless qualified.
• Call a professional: If a sealed system fault is suspected (leak, blocked capillary, weak compressor), contact an authorized Indesit service center.
