Another possibility is the vent tube being of too great a length. It shouldn't have any dips or bends to create anything similar to a plumbing p trap. If it is bent to create one, pull the tube and/or trim it a little shorter to prevent the vapor from liquifying into the tube preventing proper ventilation.
