If a fault is currently active, it is shown every 10 seconds on the display programme switch or the service terminal ST220. If the dot lights up in the left half of the display programme switch, the system was unable to completely initialise after being switched on. Either there is an obstruction or something in the system itself has become jammed. The dot extinguishes as soon as the door has been opened completely and closed again once. For troubleshooting and fault elimination see the fault table in the wiring diagram, "Fault messages" section.
