Maytag washer mhw6000xg2

Not filling any setting but the valve does operate in diagnostic mode. Got an f6e2 communication from ui to ccu error I got continuity on the wires, I ruled out user interface and I have my ccu voltages where I should. The door is locking. When I select any cycle and hit start the door locks and then you get some clicking in the ccu as power is turned on and off to the valves and the it just sits there till it times out and the door unlocks.

I did check the muc wiring but I did not chech the fuse on the board. If that board or fuse are bad would it error on the diagnostic test? I saw it tumbling but I didnt see it spinning at full speed but I was reading the tech manual while running diagnostics. Any help

This is a disruption in the data flow between the UI and the CCU.  This is the exact same type of problem as the F11 error code in the old Duets-- communications problem between the CCU and MCU.  

 

The harness itself can (and usually does) check good.  That's not usually the problem.  The problem is at the harness connection points where the molex connector on the harness connects to the boards at either end.  The tines can become loose or the pads on the board may become oxidized.  Here's a technique that I've used with great success in these types of problems.  This video shows the repair for the F11 on a Duet but the same idea applies to your situation with your washer:

Thanks everybody it turned out to be a bad mcu board. It seemed to test ok but I just had to check it at the right time to catch it losing voltage and failing.
