If the dirt container won’t come out, make sure the lock and seal lever below the dirt container is turned to the left. If that doesn’t work, 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.
Make sure not to overfill the dirt container. Always empty the container when the dirt reaches the “full” line.
