whirlpool 940 no start

I tried to start my dishwasher tonight. I closed the door pressed the button I normally push and the right lights came on and I heard a click and then nothing. The lights all work normally but it won’t do anything else.

I pulled the cover and started the unit with my meter hooked to the fill switch and got very low voltage (less than 1 VAC). the ohw reading from the fill switch is in range. the overflow float is working. tested the voltage output on the control board and it is the same as the reading on the switch.

i went through the wiring diagram trying to test all the circuits that would prevent power to fill switch cant find anything.

what do i test next?

I used wrong model number in my first post the correct one is DU940QWDQ3
