We are using EdgeStar DWP62SV dishwasher for almost three years. Recently I've noticed, that dishes come out wet and not hot to the touch like they used to. After looking around, I found that the heating element was broken in two. So far, I've:
1) Replaced the heating element. New element measured around 6 Ohms. Still no heat after that.
2) Replaced the thermostat even though I was measuring continuity on the old one. Still no heat.

Is the control board the only remaining thing that it can be?
I hear some people talking about diagnostic modes but not sure how to do that.
Any advice on where to go from here?

Thanks in advance for any help.
