Kenmore dishwasher not working

I have a kenmore diswasher that won’t start. When I put it into the Diagnostics Cycle (using SANI RISE-AIR DRY-SANI RINSE-AIR DRY) all of the keypad LEDs come on and all segments of the two digit display come on. I’ve taken a multimeter and checked internal wiring. The vent actuator assembly and float switch may be suspect. I’m not sure if either of these two items would cause the front panel to light up as it does. Perhaps the control board is kaput ?

What happens if you try to start the dishwasher?

If I try to start the dishwasher, nothing happens.
