• The grill plates have not been properly placed on the plate hooks and therefore, the sensors cannot correctly detect the food.
To rectify this problem, turn off the appliance and allow it to cool down. Then install the cooking plate correctly.
• You started cooking food between the plates without preheating.
To rectify this: turn off the appliance, remove the food, close the appliance. Turn the appliance back on, select and confirm a programme and wait until preheating has finished.
• If the problem persists despite adhering to the advice above: the appliance may need to be repaired.
