Cause and remedy
A temperature limiter switches the vacuum cleaner
off automatically if it gets too hot. This can occur
when the airways are blocked by bulky objects.
Switch the vacuum cleaner off immediately using
the On/Off footswitch . Switch off at the wall
socket and unplug it.
After removing the cause, wait for approximately 20–
30 minutes to allow the vacuum cleaner to cool
down. It can then be switched on again.
The dust container is full.
Empty and clean the dust container (see "Mainten-
ance" – "Emptying and cleaning the dust con-
tainer").
The fine dust filter is soiled.
Clean the fine dust filter and the filter mat (see
"Maintenance" – "Cleaning the fine dust filter").
