Washer overfills. Can blow compressed air into clear tube from air dome box to actuate switch and stop the filling. Can hold air gently with compressor while the fill/agitate/fill cycles run. Does not overflow on rinse. Can easily blow thru hose when both ends are disconnected. Can blow thru hose into box from the top easily. Have read many other threads having to do with this issue. Sounds like if the tube is clear, the water shuts off if it is unplugged while filling, air blows both ways thru the tube, it has to be the load size pressure switch...I guess my question is - How much air pressure should it take to trip the switch and stop the water? When I went thru this just last May, I bought a new switch. (saved the old one) Now, both switches respond the same. I can trip the switch with my air compressor and "hold it", but I can't trip it by merely blowing in the tube by mouth. (and I'm usually full of air) Can these switches just be junk?
