My Maytag washer overflows at every water level setting. I replaced the Water pressure switch part # 208201 and it still overflows. The hose is connected and in good shape. When it is filling I can unplug the machine and the water stops. Could it possible be the timer/motor?
Here are your parts

Remove the tube at the water level switch and blow into it, could♦ be it is clogged at the tub.
If this does not fix it, get a piece if tubing with the same internal diameter.
Attach this to the level switch, start a cycle and blow into the tube, you should be able to stop the water flow without blowing too hard.
If you can stop it then odds are the tubing is leaking air. Try cutting off 1/2 inch and reattaching it to the level switch.
If this does not work replace the tubing.
