If several faults occur, the fault codes are added up.
Example: If both the sensor at the cylinder top and the integral
sensor are faulty, the display shows fault code 6 (= 2+4).
Application scenarios for emergency mode
If the appliance shows fault code 8, you can manually activate
emergency mode. If a different fault occurred previously, but did
not cause the appliance to switch off, the display will show a fault
