It’s not the breaker. I changed the control board. The switch seem to be working. Is there a protection circuit or something else that I’m missing? Are there specific points that I can check for power?

The first thing I would do is to check the power source. Check the plug first, it suppose to be a 120V between the hot and the neutral. If it checks OK then unplug the power cord, remove the bottom panels and check the terminal block for broken connections. If it’s fine then plug the power cord and check for the proper voltage: between the black and the ground should be a 120V and between the black and the white should be a 120V. If everything is fine then check the door switch for the continuity.
Good luck.

Still not working. Is there a place to find a schematic?

Did you check both the “on-off” and the door switches? Double check all connections at the control board.
The wiring diagram for the Bosch dishwasher you can find only at Bosch.

On this site, there are wiring diagrams in the find parts section. Keep looking they are there. On my SHU4306, I discovered there is an interlock for the front panel on the main power switch. The front panel must be installed for the main power switch to send power to the control module and other power rails on the drain/circulation motors. If you get no LEDs, I’d suspect the power switch or between the switch and the black-white-green power lines. On my unit, there are no fuses, motor circuit breakers or other links. If the unit shorts, it takes the external circuit breaker. Hope that helps.
