Trouble Possible Cause Corrective Action
The suction process in
the continuous operation
or automatic operation
stops abruptly and the rel-
evant displays are still on
(20 / 22, Fig. 2).
• The suction turbine is overheated�
• The suction turbine is defect�
• Switch the unit off and allow to cool down for at
least 60 min�
• Check whether the suction tube is blocked� Elimi-
nate blockage�
• Switch the unit off and then on again, so that the
filter cleaning process can be carried out. Change
the fine filter (see chap. 6.3) (if the filter cleaning
function does not improve the suction performance)�
• Change the suction turbine�
When the unit is switched on,
not all of the displays light up.
• The display which does not light up
is defect�
