Started by opening enough panels (2) on back of machine to pinpoint failure. Did a web search on replacing the valve. Chose the web video sponsored by Appliance Parts Pros. Clear step by step approach, from accessing the valve through replacement. Removed part per instructions and then hunted for replacement unit on APPro’s database. Needed to go to chat to order specific part because of mis-direction in database. Chat operators knew their stuff and were most helpful. Ordered part for one-day delivery as my schedule did not permit wait. Part arrived and seemed easier to install than remove.
