The problems started with the washer not working when trying to use hot water. It would work fine if using only cold water. When trying to run a cycle with warm or hot water there was a buzzing sound that I tracked back the hot inlet solenoid. I went thru the diagnostics and it was F8E1, which I assumed a slow water fill since no hot water was coming into the tub. I ordered and replaced the fill valve. After putting it all back together it is doing the same thing as before, and the hot water solenoid is buzzing again. The only I can figure out is that the new full valve is bad. Need help diagnosing this.
