Cause and remedy

when the airways are blocked by bulky objects.
Switch the vacuum cleaner off immediately using
the On/Off foot control . Disconnect from the
electricity supply. 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.
