If there IS suction at the back of the machine with the hose removed, follow these steps:
- Unplug the unit from the outlet.
- Check the Pre- and Post-Motor filters for debris. Dirty filters can restrict airflow. The Pre-Motor Foam Filter is square. You can find it in a pull-out tray under the Dirt Tank. The Foam Filter may be hand washed in cold water with mild detergent. Reinstall the filter when it’s completely dry.
The Multi-Layer Post-Motor Filter is rectangular. It can be found on the side of the machine. *Note: The white Multi-Layer Post Motor Filter isn’t washable.
- Make sure the Dirt Tank is empty. Check the Upper Tank for build-up or clogs. If it needs to be cleaned, use a short, Phillips-head screwdriver and take off the separator plate with a cloth (can be dampened with water or mild detergent). Replace Dirt Tank.
- Check for good suction at the end of the upholstery hose. If there’s good suction, make sure the hose is connected firmly to the lower hose on the back of the vacuum. If there’s no suction, check the hose for splits, cracks, or clogs.
- Make sure the Brush Roll is rotating. If it isn’t, take the access plate off and examine the brush and belt for damage. The access panel can be taken off by lifting the four tabs on the bottom of your machine.
- Detach the Upper Hose from the machine. Insert a broomstick into the hose to push any obstruction through.
- Remove the screw from the left side of the Lower Hose on the back of the unit. Straighten this section of hose by pulling it down or laying the unit on its side with the lower hose towards the top side. Look through the hose for any obstruction. Use a broomstick to unclog the hose.
If vacuum continues to lack suction or blow dust, call BISSELL Consumer Care (see above).
