F-28 error, door is locked, won't reset..

Mica, this is a communication error between the two control boards, or between one of those controls and another component of the washer. We normally order both boards (ccu & mcu) because sometimes we only need one, but we do use both occasionally as well. It is a very costly repair. The checks to determine which is failing is very time consuming and frustrating so we opt to just replace one or both and get the washer working again. If you’d like a video we can track one down. Let us know.
