I replaced the water inlet valve assembly. To replace it I found it easier to remove the top of the washer to get to the clips holding the control panel in place. The process was straightforward and simple. Re-assembly was also simple. I did find a second problem when completing the project. The pressure hose to the far right of the control panel was leaking air and gave me another error code. I cut off about a half inch of the hose and slipped it back onto the connection and that solved all the problems. There are some good YouTube videos on the process that are worth watching. It saved me at least $150 dollars over a callout.
