E5 appears on the display, unit may run the fan but not cool properly, and ice production is very slow or absent.

Safety first: Disconnect power before cleaning or accessing the rear of the unit.

Cooling and airflow checks:

• Power cycle and cool down: Turn the unit off and unplug it for at least 30 minutes to allow the compressor to cool.
• Check placement: Ensure the Gastroback ice maker is not placed in a confined cabinet or against a wall. Provide at least 10–15 cm clearance on all sides and avoid direct sunlight or heat sources.
• Clean condenser and fan: Use a soft brush or vacuum to remove dust from the condenser coil and fan blades at the back or underside. Ensure the fan spins freely by hand (with power disconnected).
• Restart: Plug in and run the unit. If E5 reappears quickly and the compressor is very hot to the touch, the overload protector or compressor may be failing.

Ongoing E5 errors after cleaning and improving ventilation typically require professional diagnosis of the compressor circuit.
