Protecting the Vacuum's Motor

For more assistance with your vacuum's motor protection, visit support.BISSELL.com.
There is an internal thermal protector in your vacuum that protects it from overheating. It controls
the main vacuum motor only, not the brush motor. When it activates, the main motor will stop.
The front lights and brush roll will stay on but there won't be any suction. If this happens, follow
these steps:
1. Turn vacuum OFF and unplug from electrical outlet.
2. Check for the source of overheating problem (full dirt tank, dirty filters or a clog) and fix by
following the steps in the "Vacuum won't pick up dirt" troubleshooting section.
3. When the motor cools for approximately 30 minutes, the thermal protector automatically resets
and cleaning may continue. If the vacuum will not turn ON or the thermal protector continues to
activate, contact Consumer Care.

Resetting the Brush Motor

For more assistance with your vacuum's brush motor, visit support.BISSELL.com.
There is a circuit to protect the brush motor. If something becomes lodged in the foot and the brush
shuts off, turn the cleaner off and unplug from the outlet. Remove the obstruction. The brush will
automatically reset when the cleaner is plugged in and turned back on.
WARNING
• Turn power switch OFF and disconnect polarized plug from electrical outlet before performing maintenance or troubleshooting checks.
• Before using your vacuum, make sure that the dirt tank is in locked position and that all filters, both pre- and post-filters, are in
place. DO NOT operate your vacuum without these filters.
• Do not operate vacuum with damp or wet filters. Allow components to dry before reassembling the dirt tank.
• Do not use without filters in place.
Note: Any other maintenance or servicing not included in this manual should be performed by an
authorized service representative.
