The washer had intermittent LF errors and issues with the bleach and fabric softener filling not emptying or filling with water. I had a service call from the big mall chain-store come out and paid $99 for him to tell me all the tests checked okay. I knew it had to be something with the valves even though they ohmed out okay. I ordered a new valve assembly that afternoon and it arrived the next morning. After viewing the how-to video on this site, I was able to install the new valve assembly in less than an hour. It was a pretty easy fix, and the washer is working great again.
