-Check the inner and outer circular filters and post-motor filter for debris. Also check the upper-tank louvers, as they may need to be rinsed. Failure to properly maintain the filters could result in damage to the motor. Also, if there is a clog, this will cause the motor to get loud.
-Check for good suction at the end of the upholstery hose. If there is good suction, make sure the hose is firmly connected to the lower hose on the back of the vacuum.
-Check the brush to see if it is rotating. If not, remove the access panel by removing the 5 screws under your machine. If a new belt is needed, this can be ordered by calling Bissell Consumer Services at 1-800-237-7691, Monday-Friday 8:00 a.m.-10 :00 P.M. ET. Saturday 9:00 a.m.- 8:00 p.m. ET.
Check the back of the machine after removing the hose where it attaches to the back of the vacuum. If there is suction, most likely there is a clog in your machine. Check the upper hose for clogs by detaching the hose from the machine. Push a broomstick into the hose to push any obstruction through the end of the hose. If you are still having difficulty, we recommend taking your machine to a Bissell service center.
