There's a pressure switch that controls the water level. The switch itself is inside the raised control panel and may be bad, its got cams and contacts that can wear out. The switch is connected to a hose that is connected to the tub bottom at the other end. As the water level rises in tub it rises in hose, compressing air that eventually pushes a plunger in the switch, turning water off. You can usually see and access the hose by taking back off washer back. after unplugging and turning off water. The hose or the connection at top may be leaking, preventing proper pressure build up, it may have a kink or twist in it. Its usually bigger towards the bottom than top, some are clear vinyl, some 'rubber'. Some are two or more lengths connected to other pressure control devices. We had a washer once that had a clear plastic tube larger in diameter than the hose, spliced into the line about half way up and hanging from a bracket . It was some kind of pressure control device, you can adjust water level by hanging it from different holes in the bracket. It had fallen off and was hanging way to low. All I had to do was re-hang it. If you can safely run washer thru a fill cycle with back off you may be able to see a problem in a clear hose or watch for drips indicating a leak. Flip the water level switch back and forth a few times.
If you have to replace the switch, after unplugging, etc., take a picture(s) or make a drawing showing all wire colors and where they hoses and connect. Sometimes connecting hose at bottom can be a hassle. But its relativly easy job replacing switch and/or hose, and that's on the level.
