Does not fill complete

Dishwasher Repair

I have a Whirpool diswasher that does not fill to the proper level. It fills part way then water shuts off. I can hear the pump sucking air. If I open it, restart the timer to beginning, and restart, It continues to fill and pump no longer cavitates. Is the fill cycle time based? Is it adjustable? I don’t see any restriction to slow the water flow unless there is a filter or screen someplace…

Thanks

The first thing I would do is replace the water inlet valve (#26 on the tub break down diagram).

The water inlet valve has a screen inside, which most likely is clogged with a hard water deposits.
