| Code | Fault / Diagnostics | Appliances | Action |
|---|---|---|---|
| A1 | A1 error code displayed, appliance may not start or may continuously drain. Info: Anti-flood system activated due to a water leak in the appliance's base tray. | Refrigerator | |
| A2 | Fridge temperature too high Info: The refrigerator compartment is too warm. This may be due to a sensor fault or an issue with the damper control or fan. | Refrigerator | |
| A3 | Drain timeout error Info: The dishwasher is unable to drain water within the specified time. This is usually due to a blocked filter or drain hose. | Dishwasher | |
| A4 | Temperature sensor (NTC) error Info: The dishwasher has detected an issue with the temperature sensor, which may be open or short-circuited. | Dishwasher | |
| A5 | Pressure switch fault Info: The pressure switch, which monitors water level, is blocked or faulty, giving an incorrect reading. | Dishwasher | |
| A6 | Water fill timeout Info: The dishwasher has failed to fill with water in the allotted time. The water supply might be off or the inlet valve faulty. | Dishwasher | |
| A7 | Diverter valve fault Info: The diverter valve, which directs water to the upper or lower spray arms, is faulty or jammed. | Dishwasher | |
| A8 | Heating timeout error Info: The dishwasher is not heating the water correctly. This could be a faulty heating element or a temperature sensor issue. | Dishwasher | |
| A10 | Water inlet solenoid fault Info: The water inlet valve (solenoid) is not opening or is faulty, preventing water from entering the appliance. | Dishwasher | |
| ER CF | Communication Failure Info: Communication error between the main control board and the user interface/display board. | Refrigerator | |
| ER DS | Defrost Sensor Fault Info: The defrost sensor (thermistor) located on the evaporator is shorted or has an open circuit. | Refrigerator | |
| ER IS | Icemaker Sensor Fault Info: The temperature sensor for the icemaker is reporting an error. | Refrigerator | |
| F01 | Control board communication error Info: The main control board has detected an internal communication failure. | Oven | |
| F1 | Fridge thermistor faulty Info: The refrigerator compartment's temperature sensor (thermistor) is open or short-circuited. | Refrigerator | |
| F02 | Motor jammed or tacho detached Info: The motor is not turning or the control board is not receiving a signal from the motor's speed sensor (tacho). | Washing Machine | |
| F2 | Water fill error Info: The dishwasher is unable to fill with water. Similar to A6, this points to an issue with the water supply or inlet valve. | Dishwasher | |
| F03 | Oven temperature sensor (NTC) open Info: The control board has detected an open circuit in the temperature sensor, meaning it's likely disconnected or failed. | Oven | |
| F3 | Freezer thermistor faulty Info: The freezer compartment's temperature sensor (thermistor) is open or short-circuited. | Refrigerator | |
| F04 | Oven temperature sensor (NTC) shorted Info: The control board has detected a short circuit in the temperature sensor. | Oven | |
| F4 | No feedback from freezer fan Info: The control board is not detecting rotation from the freezer's evaporator fan. 5 Elite Techs Verified | Refrigerator | |
| F05 | Pump blocked or pressure switch fault Info: The machine has failed to drain the water. This is usually due to a blocked pump filter or a faulty pressure switch. | Washing Machine | |
| F5 | Air damper fault Info: The motorized damper that controls airflow from the freezer to the fridge is stuck or faulty. | Refrigerator | |
| F06 | Door lock error Info: The machine cannot detect if the door is open or closed correctly. This could be a faulty door lock mechanism or a wiring issue. | Washing Machine | |
| F6 | Button/key stuck Info: A button on the control panel is detected as being continuously pressed. | Washing Machine | |
| F07 | Heater relay stuck Info: The main control board has detected that the water heating element relay is stuck in the on position. | Washing Machine | |
| F7 | Defrost heater fault Info: The defrost heating element is not drawing current, indicating it is open circuit or has a wiring issue. | Refrigerator | |
| F08 | Selector switch error Info: The function selector switch is sending an invalid signal to the main control board. | Oven | |
| F8 | Water turbidity sensor fault Info: The sensor that measures how dirty the water is (turbidity sensor) is not providing a correct reading. | Dishwasher | |
| F09 | Software / EEPROM error Info: A setup or memory error has occurred on the main control board. This can sometimes happen after a power surge. | Washing Machine | |
| F10 | Overheating detected Info: The oven's safety thermostat has detected an excessive temperature, possibly due to a faulty cooling fan or a stuck heating element relay. | Oven |
