All of the following steps are considered routine maintenance and should be done regularly.
1. First, check to see if the dirt cup is full. Emptying it may fix the problem.
2. Next, let’s check the dirt cup area. Start by removing the lower dirt tank. Clean the screen and check the center tube for dirt accumulation (pictured below).
3. Check the dirt inlet. This is the opening located behind the canister and will only be visible once the canister is taken off the machine.
4. Check the diverter area at the back of the machine. This is a clear plastic window found just below the cord/hose wrap (pictured below). When the hose-wand is attached to the base, the diverter should be in the up position. If a clog is visible near the diverter, remove the diverter cover by removing the 3 screws and clearing the obstruction.
5. There may be a clog in the upper hose. Detach the hose from the machine by pushing the gray tab in and pulling the hose out. Push a broomstick into the hose to push any obstruction to the end of the hose where it can be removed. Note: a coat hanger is not recommended for clearing clogs because it can damage the hose. If the hose is still clogged, you may need to order a new one. You can do so by clicking here: http://www.bissell.com/parts/?sc=part&productid=2464&partid=4987
6. If the above steps haven’t worked, there’s likely a clog in the lower hose.
Start by reclining the unit and rolling it over so the backside is facing up. Remove the 3 screws from the clear plastic diverter cover and remove the foot hose (the small, clear hose next to the wheel). Look through the foot hose for obstructions. Don’t use a broomstick for the foot hose- it won’t fit. If the clog is near the end of the lower hose, it may be possible to pull it out.
If you can’t clear the clog in the lower hose, please take your vacuum to a technician. You can find your nearest BISSELL® Authorized Service Center by clicking http://www.bissell.com/service-centers/ or by calling 1-800-263-2535, available 24 hours a day.
