and unplug it.

Cause and remedy
A temperature limiter switches the vacuum cleaner

when the airways are blocked by bulky objects.
Switch the vacuum cleaner off immediately using
the On/Off footswitch . Switch off at the wall

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 vacuum cleaner is running an automatic cleaning
process which you can hear running.
Wait for approx. 20 seconds until this cleaning
process has finished.
