Possible cause and solution
A temperature limiter switches the vacuum cleaner off
automatically when it gets too hot. This can occur
when the airways are blocked by bulky objects.
Turn the vacuum cleaner off immediately using the

After removing the cause, wait for approximately 20 -
30 minutes to allow the vacuum cleaner to cool down.
It can then be turned on again.
