Adler ice maker displays E08; unit fills and circulates water but no ice forms on the evaporator.

Safety first: Unplug the unit. Sealed-system work must be performed by a certified refrigeration technician.

• Check evaporator frost pattern: Remove the front panel and observe the Adler evaporator plate during a cycle. A partial or no frost pattern indicates a refrigeration issue.
• Verify fan and pump operation: Ensure the condenser fan and circulation pump are running properly; poor airflow or water flow can mimic low refrigerant symptoms.
• Inspect for oil stains: Look for oily residue on refrigerant tubing, joints, and the evaporator, which can indicate a leak.
• Sensor check: Test the evaporator temperature sensor (if separate from E02 thermistor) for proper resistance values per Adler specs.
• Contact a technician: If airflow and sensors are normal, an Adler-authorized technician should check system pressures, locate leaks, and recharge or replace components as needed.
