Query: Bad Description

The product description does not tell you that this machine will not work with a water filtraton system. It has a water level probe that picks up on the impurities in the water to determine water level. As a result the machine will start by itself and will not shut off. Get the mop out, you will need it...Oh, and Bunn, Clark the distributor and webstaurantstore.com where I purchased the maker will not exchange it.
