On the left bottom door of the freezer there is a bolt that holds the door - when the door is open, water drips from the nut. Also inside the bottom freezer at the back water leaks from the grill. I had a large build up, which I thought was the reason the water was leaking on the floor. Now that I have cleared the build up of ice and the freezer is empty, I've watched the water drip from the nut on the bottom of the door. Is there anything that I can do to fix that?
