Pull out the water bottle. Look in dryer where bottle was there's a silver button if u press that the light will go out. If this happens then wrap some duct tape around the small plastic bit that sticks out on the back of the water bottle then place bottle back in place.... I just done this and now mines working again....ps you need to put your arm all the way in where bottle it kept. Hope that make sense and works.
