My washer (model number MVWB765FW3) is flashing the F6 E3 code. I was told by a local service guy that the part number for the control board has changed meaning a new part it will no longer communicate with the user interface in the machine. He said the control board is on back order and the user interface is no longer being made. Is this true? I can’t believe I would need to replace a two-year old washer!

Both boards are still readily available and are not on backorder at most online suppliers. Maybe his local supplier has them back-ordered but that is not the case for online suppliers. I would imagine he didn't want to get involved with this repair because the price of the boards are very high and without ordering both boards which would cost you close to what a new machine would cost it's basically a gamble as there is no way to determine which board is causing the error so replacing both is really the only option you have and it's not worth spending that much on a two-year-old machine.
