Maytag Neptune Water overflowing

Having trouble with Washer overloading. Here’s what I’ve done so far…

Maytag Neptune MAH 3000 AWW (Purchased about 1998)
• Tub overflows
• Turn washer off , water stops coming in
• Unplug washer, water stops coming in
• Checked pressure switch……continuity from right purple to blue good, looses continuity when I blow into pressure switch
• Continuity between left purple and gray……looses continuity when I blow into switch
• I start washer….let it fill up a little and blow into pressure switch….but water does not stop
• I have noticed that when settings are on cold/cold hot water still fills tub
• When I blow into pressure, I can hear two switches go off in the switch
• It doesn’t seem the water valves are sticking because they do turn off when I turn the machine off.

You did a really good job here of checking things out.

Since the water does not stop when you blow in the hose I think the issue is the switch itself, the wiring between the switch and the control unit or the control unit.
