washer was overflowing-- not registering that the tub was full

I replaced both the tube and the pressure switch and still no luck. turns out that i didn't need either part. the little box that the tube hooks on to at the bottom left of the tub had a clog in it. we disconnected the tube from the switch and just blew through it. the clog broke loose and my washer works again!! decided that i was leaving the new parts on the machine. one less thing to worry about in the future.... ????
