LOSS OF SUCTION AND THERMAL SWITCH

If your cleaner loses suction power, first check that the hose and other accessories in use
are not blocked. To clear a blockage, insert a long object such as a wooden spoon into the
nozzle connector to clear the airway.
If the hose or accessories are not blocked, then check that the filtration system is not
blocked. The filtration system can be serviced as follows:
