1. First, make sure the bag isn’t full
2. Check the pre- and post-motor filters for debris. The pre-motor filter is washable in warm water with mild detergent. The post-motor filter is not washable.
3. Does the “change bag” indicator remain orange with the hose removed? If the “change bag” indicator is orange with the hose attached, but turns off when the hose is removed, the hose may have a clog. Work the clog loose by massaging the clogged area and/or gently twisting the hose where it’s clogged until the clog works itself free.
4. If the change bag indicator remains lit, please take your vacuum to a technician. You can find your nearest BISSELL® Authorized Service Center by clicking http://www.bissell.com/support/product-support/service-centers or by calling 1-800-237-7691, available 24 hours a day.
