GE Washer Stops Filling (works after reset)

Hi,

I have a GE GCWN5050M0WS and it stops filling a few seconds to a few minutes into the first fill cycle. Sometimes you can just press the button to start it again, other times you need to unplug the unit to get it to fill again. Once it gets past the initial fill, the rest of the cycles work. I am able to get loads of laundry through but it’s getting annoying and worse. What can be the problem?

Thanks in advance,

Keith
