20OCT18. I also had this issue. I replaced the mother board, then had to replace the water valve.
What is happening ? The valve is getting hot and it takes too much current to make it energize and stops filling.
To test the: Turn on your washer with the sanitize setting. let it run for about 5 minutes then cancel it and run it again. Mine failed … wait an hour and it fills. I wasted money on a computer board where it was the valve due to a poor design…
