I am getting a Sud code and then an F35 error on my Maytag frontload washing machine. I have unplugged it...to reset and sometimes it works. Other times it doesn't. How can I fix it?

The F35 error code indicates an analog pressure sensor error. The analog pressure sensor is the component that detects water level in the washer tub. This error can usually be cleared but it will occur again if the main control board still detects a problem with the signal from the analog pressure sensor. This error code can be caused by a problem with the air pressure tube between the bottom of the washer tub and the analog pressure sensor. If you are able to unplug the washer and check this air pressure tube, you may be able to resolve this problem.
