Maytag Dishwasher
MDBH989AWW2

Runs great for 3 years.
3 days ago lites stay on at 'normal' and 'heated dry' buttons (then I'd just push start) but won't run then after 30 seconds go out.
Same thing over and over.
Recycled power, waited, no change.
Local App guy sells me a $200 control board, this is it for sure.

Remove power, Install board, power back on...same exact thing

Have 110vac to board plug in.
Have 110vac to door switch (com/NO) switch works fine.
Have 110vac to each side thermo button on control board.
No wiring diagram.

Original board was p/n W10250166A
New board is W10298356 physically and connection wise exact same.

But aparently it's not the board

Any help appreciated.

I'm a retired elevator mechanic of 34 years.
Pretty handy with a meter and such.
Just not sure where as I have no wiring diagram.
If I knew where some test points were I could figger it out.
Right now with the above in order, I need to know where the signal is to start button. I'm guessing it's thru the ribbon cable with a 5v logic or similar to a start/run signal.
Anybody got some pin #'s for any of the buttons on panel?

APP will not let me attach the file.
Probably too big.
So I put it on DataFileHost.
Here it is, hopefully you can get it.

upon further review:
jump pin p1-12 to p1-4 starts the machine on it's way
board is fine, problem is between the board and the button on panel
that's all one piece with ribbon cable so here goes
