Access our premium database of error codes, common faults, and professional repair solutions for Ardo appliances.
Freezer evaporator sensor fault
The defrost sensor (NTC) on the freezer's evaporator coil has failed. This will affect the automatic defrost cycle.
Access the evaporator coils in the freezer. Test the defrost sensor and its wiring. Replace the sensor to restore proper defrosting.
Door lock mechanism failure
On pyrolytic (self-cleaning) models, the door locking mechanism has failed to engage or disengage correctly.
Check for any obstructions preventing the lock from moving. Test the door lock motor and switches. The lock assembly may need replacement.
Ardo F5: Cooling circuit or defrost system anomaly in Refrigerator / Freezer; compartment temperature deviation.
The control board has detected a failure in the defrost heater circuit. This will cause ice to build up on the evaporator coils.
Manually defrost the appliance. Test the defrost heater element for continuity. Also check the thermal fuse, which is part of the same circuit. Replace faulty components.
Main board communication failure
A communication error has occurred between the main power board and the display/user interface board.
Check the wiring harness connecting the electronic boards. A loose connection is a common cause. If wiring is good, one of the boards has failed.
Ardo F07: Operational cycle fault detected during Oven / Microwave program execution.
A fault has been detected on the main power board, often related to a power supply component or relay.
Inspect the board for visible signs of damage like burnt components. This error usually necessitates the replacement of the power board.
Compressor failure or overheat
The main board has detected an issue with the compressor circuit, or the compressor's thermal overload protector has tripped.
Check if the compressor is running. If not, test the start relay and overload protector. Ensure condenser coils are clean and the fan (if present) is working to prevent overheating.
Ardo F08: Motor drive or inverter rotation anomaly in Oven / Microwave; drum/motor fails to spin at target RPM.
The tangential cooling fan, which cools the oven's external surfaces and electronics, is not operating.
Check if the fan blade is blocked. Test the fan motor for continuity and voltage. Inspect wiring. Replace the cooling fan unit if faulty.
Freezer fan motor failure
The fan that circulates cold air within the freezer (and often to the fridge) is not working.
Check if the fan blade is obstructed by ice buildup. If clear, test the fan motor for continuity and check for voltage from the control board. Replace the fan motor if it has failed.
Ardo F9: Motor drive or inverter rotation anomaly in Dishwasher; drum/motor fails to spin at target RPM.
The diverter valve, which directs water to the upper or lower spray arms, is stuck or faulty.
Check the diverter valve for blockages. Test the valve's motor and position switch. The diverter valve assembly may need to be replaced.
Main control board (ECU) fault
A critical error has been detected on the main electronic control unit. This can be caused by a power surge or component failure.
Try resetting the machine by unplugging it for 15 minutes. If the error persists, the main control board will likely need to be replaced.
Control board memory (EEPROM) error
There is a data corruption or communication error within the main board's memory chip.
This is a non-recoverable error. The main control board must be replaced and potentially programmed for the specific model.
Ardo H: Water/air heating failure in Dishwasher; heating circuit does not reach set temperature.
This is not an error, but an indicator that the appliance is in the heating phase of a cycle.
No action is required. Wait for the cycle to complete. If the 'H' flashes, it may indicate a heating problem.
Oven overheating / Safety thermostat tripped
The oven cavity has reached an excessive temperature, tripping the safety cut-out thermostat. Often caused by a cooling fan failure or stuck element relay.
Let the oven cool down completely. The safety thermostat may need to be manually reset (a small button on the thermostat body). Investigate the cause of overheating, such as the cooling fan (F08) or a stuck element.
