Hi, I asked the question on May 27, 2020 and purchased the hot water inlet valve after your recommendation. Unfortunately, replacing this part did not fix the issue with the LF code either. I can complete a rapid wash cycle of 30 minutes as I could before but can not wash on the standard cycle without the cycle ending prematurely with the LF error code. Any other recommendations? Thanks

I am sorry to hear replacing the valve did not fix your problem. The only thing left that it could possibly be is a bad control board. The fill circuit on the board is bad or it's throwing a false error, either way the control is bad.
