Everytime I try to clean it I get an error code 25. Clean jet unable to complete . I placed the racks at the 4th level no luck even at the 6th level no luck . I know the water is supposed to get sucked into the blower to slow down the rpms but I;m stuck on what to do . Since we had this unit it's always had this problem . I've changed the clean jet several times . Anyone else have this problem ?
