| Code | Fault / Diagnostics | Appliances | Action |
|---|---|---|---|
| E01 | Door lock fault Info: The machine has detected that the door is not closed or the door lock mechanism is faulty. | Washing Machine | |
| E1 | Refrigerator compartment sensor fault Info: The main control board has detected an open or shorted circuit in the refrigerator's temperature sensor. | Refrigerator | |
| E02 | Water fill timeout Info: The machine failed to fill with water in the expected time. This could be due to a closed water tap, kinked inlet hose, low water pressure, or a faulty inlet valve. | Washing Machine | |
| E2 | Freezer compartment sensor fault Info: The main control board has detected an open or shorted circuit in the freezer's temperature sensor. | Refrigerator | |
| E03 | Drainage fault Info: The machine has failed to drain the water. The drain pump filter is likely blocked, the drain pump is faulty, or the drain hose is blocked or kinked. | Washing Machine | |
| E3 | Defrost sensor fault Info: The sensor attached to the evaporator coil, which monitors the defrost cycle, is faulty. | Refrigerator | |
| E04 | Overfill or leak detected Info: The pressure switch may be faulty or the water inlet valve is stuck open. | Washing Machine | |
| E4 | Overflow / leak detected Info: The flood protection switch in the base of the dishwasher has been activated by water. | Dishwasher | |
| E05 | Temperature sensor (NTC) fault Info: The machine cannot read the water temperature correctly due to a faulty NTC sensor or wiring. | Washing Machine | |
| E06 | Motor fault Info: A fault has been detected with the main drive motor. This is often caused by worn motor carbon brushes or a faulty tacho coil on the motor. | Washing Machine | |
| E21 | Drain timeout error Info: The water is draining too slowly. This is a more specific drain fault than E03, indicating a partial blockage or weak pump. | Washing Machine | |
| F1 | Oven temperature sensor error Info: The oven's main control board is not receiving a correct reading from the temperature sensor (NTC/probe). | Oven | |
| F2 | Water not draining Info: The dishwasher cannot drain the waste water due to blocked filters, a kinked drain hose, or a faulty drain pump. | Dishwasher | |
| F3 | Continuous water inlet Info: The water inlet valve is stuck open, causing the dishwasher to fill with water continuously. | Dishwasher | |
| F5 | Insufficient water Info: The water level sensor has detected that there is not enough water in the machine to run the cycle. | Dishwasher | |
| F8 | Door lock mechanism error Info: Fault with the motorized door lock, often occurring during or after a self-clean (pyrolytic) cycle. | Oven | |
| H | High temperature alarm Info: The internal temperature of a compartment is too high. This can be caused by the door being left open, loading a large amount of warm food, or a cooling system failure. | Refrigerator |
