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.
Thanks.
