How to replace Washer Electronic Control Board. The advantage now of "googling" and finding answers is an underused gift. I found that it needed a new control panel circuit board. It was easy to find the part number and with a little search Appliancepartspros.com not only had the part, but also a video on what to do to repair it. I ordered the part and believe it or not, I received the part less than 24 hours from ordering! The switching out the part was simple, if you pay attention. I was able to do loads of wash immediately after. I have done things like this before, but rarely does it go without a problem. This time it was easy, quick and successful.
