Bosch Dishwasher not heating water

Hi, I trying to figure out what the problem could be dishwasher not heating. I called Bosch they said probably the Control Unit. So if I get this part out is there a way to test it? I don’t see a heating element coil like old dishwashers so I guess it doesn’t use one?

I still need help with this, I have the top panel off but can’t get control module off. I see two clips at bottom but don’t seem to move far I’m afraid I’ll break it

Ok I got the Control Module out now is there a way to test it with multi-meter or something to see if it’s bad or not?
