My Little Green Series 1400 1425 is leaking from the bottom. How can I correct this?

Answer: Please try the following suggestions to get your machine to function properly: - Check to see if the black or white duck bill gasket is misassembled or missing from the collection tank; ensure the gasket will open where the flat flaps meet and then reinstall it. The duck bill should be inserted into the curved side of the collection tank. - Check to see if the solution tank/cap insert is leaking. Note: When the solution tank is filled and turned right side up, the straw on the insert may fill with water/solution causing the tank to leak for a couple of seconds. This leaking should subside after the straw empties out. - Check for proper placement of the o-ring on the cap insert. The o-ring should be between the bottle and the insert piece (part with the "straw"). If you continue to experience difficulty with your machine, please contact BISSELL Consumer Services at 1-800-237-7691 Monday through Friday from 8 a.m. to 10 p.m. or Saturdays from 9 a.m. to 8 p.m. ET.
