Thermal Protector

An internal thermal protector has been designed into your cleaner to protect
it from overheating. When the thermal protector activates, the main
vacuum motor will stop operating. If this happens, proceed as follows:
Turn the cleaner OFF (O) and unplug from electrical outlet.
1.
Check the Upper Tank area, Pre-Motor Filter and
2.
Post-Motor Filter for dirt accumulation.
Refer to the "Clearing Clogs" section above.
3.
When the motor cools for approximately 30 minutes, the
4.
thermal protector automatically resets and cleaning may continue. If
the thermal protector continues to activate after following the above
steps, your cleaner may need servicing.
NOTE: The thermal protector controls the main vacuum
motor only, not the brush motor. If the thermal protector
activates, the brush will continue to operate normally;
however, there will be no suction.
