In the midst of washing a rug (which had been washed before succesfully) the machine stopped with the control panel still locked. After much playing around with the kick panel (why do I have to take off the kick panel every time I need to pop the door and then replace it to close that safety switch to run a test?) and diagnostic test, I've come up with the following:

after pushing 1,2,3 to enter the diagnostic mode,
there was a 'LF' that I cleared in the system - we ran it last week accidentally with the valve turned off after replacing some piping, so that was no big deal.

I then push 2 to enter the self-test mode. The LED displays '1'. I push 2 again, and the LED displays '5'. I push 2 again, the LED displays '0'. I push 2 again, and the door locks (and the LED goes out), I push 2 again, the cold water fills (and then stops). I push 2 again, and I see the drain pump go and the water empties out of the washer. However, no amount of me pushing 2 anymore will change anything else. There aren't any directions to this effect (additional pushing buttons) in the technote - part number W10252711A so I'm not sure what else I need to do to have it to the other parts of the self test.

If I try a normal cycle, the door locks, and then nothing else happens.

The continuity/resistance checking seems to indicate a problem with the 'Motor resistance test', that came back at infinity. The pump motor as well as the inlet valve were ok. I could not find the tachometer pins - they're listed as '4' and '5' and I don't see anything like that on the diagram. So I guess I'm tending towards motor/MCU, but I'd really like a self test to run correctly to give me another data point. Thanks.
