closing the door. If the fault is still displayed afterward, use the reset function or
briefly interrupt the power supply. Please contact the manufacturer if the fault could
not be reset after restarting.
Important:
If you do not find the displayed device status in the System status table, this indi-
cates an internal device fault. In this case, you should contact the manufacturer.
