agree with that - the Auto mode has a rubber stopper that acts as a 1-way valve which allows water in from the rear drain but not out. The recirc setting has a fixed stopper so water can't do either. The stopper in the auto setting is usually what needs replaced and is part of the rebuild kits they sell. if you ever have one apart, the engineering is not all that impressive imho.
