| Code | Fault / Diagnostics | Appliances | Action |
|---|---|---|---|
| E0 | Freezer sensor fault Info: The temperature sensor in the freezer compartment has failed (open or short circuit). | Refrigerator | |
| Ed | Defrost sensor fault Info: The defrost sensor, located on the evaporator coil, has failed. | Refrigerator | |
| Er | Icemaker failure Info: A fault has been detected with the automatic icemaker module. | Refrigerator | |
| E1 | Refrigerator sensor fault Info: The temperature sensor in the fresh food (refrigerator) compartment has failed. | Refrigerator | |
| E2 | Drain pump error (Condenser models) Info: The pump that removes condensed water from the reservoir is blocked, or the water level sensor is faulty. | Tumble Dryer | |
| E3 | Water not heating Info: The water is not reaching the target temperature. This is likely due to a faulty heating element or a defective temperature sensor (NTC). | Dishwasher | |
| E4 | Communication error between main board and display Info: The wiring between the main control board and the user interface/display board is loose, damaged, or one of the boards has failed. | Refrigerator | |
| E5 | Heating system fault Info: The heating element has failed, or a thermal overload cut-out (TOC) has tripped and needs resetting or has failed. 5 Elite Techs Verified | Tumble Dryer | |
| E6 | Communication error between boards Info: A fault in the connection between the main PCB and the display board. | Tumble Dryer | |
| E7 | Temperature sensor fault (short circuit) Info: The NTC temperature sensor has failed by short-circuiting. | Dishwasher | |
| E8 | Cooking zone overheat Info: A cooking zone has overheated. This can be due to empty or unsuitable cookware being left on the zone, or a faulty temperature sensor. | Hob | |
| E12 | Water overflow Info: Too much water has entered the machine. This is usually caused by a faulty water inlet valve that is stuck open or a malfunctioning pressure switch. | Washing Machine | |
| ER21 | Touch control panel error Info: A communication issue with the touch control board, possibly due to moisture or a component failure. | Oven | |
| FF | Frozen food sensor error. Check thermistor resistance in the freezer. | Refrigerator | |
| F1 | Oven temperature sensor (NTC) error Info: The oven's temperature probe is defective (open or shorted) or has a loose connection. | Oven | |
| FC1 | Communication error Info: Communication failure between the main control board (PCB) and the display board. | Washing Machine | |
| F2 | Motor fault Info: The drum motor is not running. The drive belt could be broken, the motor start capacitor failed, or the motor itself is faulty. | Tumble Dryer | |
| F3 | Control board communication error Info: Failure in communication between the main power board and the user interface. | Oven | |
| F4 | Oven overheat detected Info: The oven has detected a temperature above the maximum safety limit. This can be caused by a stuck relay on the control board or a faulty cooling fan. 5 Elite Techs Verified | Oven | |
| F5 | Evaporator fan motor fault Info: The fan that circulates cold air inside the freezer/refrigerator is not working due to obstruction or motor failure. | Refrigerator | |
| F7 | Motor fault Info: Motor is blocked, motor's tacho connection is loose, motor brushes are worn out, or the motor control board is faulty. | Washing Machine | |
| F8 | Door lock fault Info: The motorized door lock mechanism has failed to either lock or unlock the door correctly. | Oven | |
| F9 | Diverter valve error Info: The valve that switches water flow between the upper and lower spray arms is jammed or has failed. | Dishwasher | |
| H | Humidity sensor needs cleaning Info: Lint and fabric softener residue have built up on the metal humidity sensor strips inside the drum, preventing accurate readings. | Tumble Dryer | |
| HD | Humidity sensor fault Info: The humidity sensor, often used for crisper drawer climate control, has failed. | Refrigerator | |
| Unb | Unbalanced load detected Info: Laundry is gathered on one side of the drum, causing an imbalance during the spin cycle. | Washing Machine |
