| Code | Fault / Diagnostics | Appliances | Action |
|---|---|---|---|
| AL03 | Dishes come out dirty and cold, cycle may not complete Info: Alternative code for a heating fault (same as E3). The dishwasher is not heating the water. | Dishwasher | |
| E01 | Refrigerator section is not cooling properly Info: The refrigerator compartment's temperature sensor (NTC) is faulty. | Refrigerator | |
| E1 | Hob shuts down during use Info: Overheating of the internal electronic components. | Hob | |
| E02 | Freezer section is not cold enough or is icing up Info: The freezer compartment's temperature sensor (NTC) is faulty. | Refrigerator | |
| E2 | A specific cooking zone shuts off and displays the error Info: Overheating of the cooking zone's surface sensor, often because a pan has boiled dry or an empty pan was left on high heat. | Hob | |
| E03 | Excessive frost and ice buildup on the back wall of the freezer Info: Fault with the defrost system's NTC sensor located on the evaporator. | Refrigerator | |
| E3 | Hob does not work correctly, may show error on startup Info: The mains voltage supply to the hob is too high or too low, outside the appliance's operating range. | Hob | |
| E04 | Machine has overfilled with water or is showing an anti-flood error Info: Too much detergent causing over-foaming, a faulty pressure switch, or a blocked pressure switch hose. In some cases, a faulty water inlet valve is stuck open. | Washing Machine | |
| E4 | Hob is unresponsive or behaving erratically Info: A communication error between the hob's user interface (touch controls) and the main power module. | Hob | |
| E05 | Machine not heating water, or cycle finishes too quickly Info: The NTC temperature sensor is faulty or has a bad connection. This prevents the machine from knowing the water temperature. | Washing Machine | |
| E5 | Cycle does not complete correctly, possible heating issues Info: The NTC temperature sensor is faulty, giving incorrect readings to the control board. 5 Elite Techs Verified | Dishwasher | |
| E06 | Machine fails to spin or stops mid-cycle Info: This error can indicate a severely unbalanced load, a fault with the main control board (EEPROM error), or a problem with the machine's calibration. | Washing Machine | |
| E6 | Dishwasher won't start when the door is closed Info: The control board is not detecting that the door is closed. This is due to a faulty door latch or door switch. | Dishwasher | |
| E07 | Motor not turning or turning erratically Info: The motor is jammed, the motor brushes are worn out (on older models), or there's a fault with the door lock preventing the motor from starting as a safety measure. | Washing Machine | |
| E7 | Dishwasher overfills or shows a filling error Info: Fault with the water inlet flow meter. The machine cannot correctly measure the amount of water entering. | Dishwasher | |
| E08 | Drum spins very fast briefly then stops, or doesn't spin at all Info: The motor's speed sensor (tacho coil) is faulty, its magnet has fallen off, or the wiring to it is damaged. The machine cannot detect the motor's speed correctly. | Washing Machine | |
| E09 | Machine is completely dead or trips the circuit breaker; motor does not run Info: A short circuit in the motor's control triac on the main control board (PCB). This is often caused by a fault in the motor itself. | Washing Machine | |
| E11 | Dryer cycle not working, clothes remain wet Info: The dryer's temperature sensor (NTC) has an open circuit or is faulty. The machine cannot regulate the drying temperature. | Washer Dryer | |
| E12 | Washer dryer is unresponsive or showing communication error Info: There is a communication fault between the main control board and the display board, or a fault in the dryer sensor module. | Washer Dryer | |
| E13 | Appliance is unresponsive, cycle won't start Info: Indicates a fault with the main control board (PCB). | Washer Dryer | |
| E14 | Drying function not heating Info: Fault related to the drying heating element or the control board's logic for the dryer function. | Washer Dryer | |
| E15 | Machine will not start, display may be blank or flashing Info: The memory chip (EEPROM) on the main control board is not programmed or has become corrupted. | Washing Machine | |
| E16 | Trips the main house circuit breaker (RCD/GFCI) when heating should start Info: The insulation on the water heating element has failed, causing a short circuit to ground. | Washing Machine | |
| E17 | Motor behaves erratically, may not spin correctly or at all Info: The motor tacho signal is present but is out of the expected range, indicating a problem with the motor's speed regulation. | Washing Machine | |
| E18 | Machine behaves strangely, cycles are incorrect Info: The main control board (PCB) installed is of the incorrect type for the machine's model or configuration. | Washing Machine | |
| F | A flashing 'F' appears on a cooking zone and it won't heat Info: No pan, an incorrect type of pan (not magnetic), or a pan that is too small or not centered is on the induction zone. | Hob | |
| F01 | Oven not heating correctly or overheating Info: The oven's temperature sensor (NTC probe) is faulty, either open circuit or short circuit. | Oven | |
| F02 | Oven cuts out during use, especially at high temperatures Info: Overheating detected. The cooling fan is not working, air vents are blocked, or the safety thermostat has failed. | Oven | |
| F03 | Oven door is stuck locked after a pyrolytic cleaning cycle Info: The door lock motor or the microswitch that detects the lock position has failed. | Oven | |
| F04 | Oven is not working, display may show error or be erratic Info: EEPROM data corruption on the main control board. The oven's 'memory' is faulty. | Oven |
