if water collection bottle is at the top then it will have a drain pump inside to lift water in to the container.if they fail they allow water to build up in a reservoir in the back.check the drain pump and for fluff blockage in the reservoir tank pipes.This requires the removal of the back panel and a multimeter to test the drain pump windings unless seized/jammed up
