replaced control board

all lights stopped working. dishwasher would not work at all. power to the washer. replaced control board and broken latch. plugged back in and still no lights and still not working. what other problem could I have? thanks.

Have you verified that there is power to the control board? I have had many cases where the wire nuts in the electrical box below the dishwasher burnt in two. Also cord ends that plug into loose outlets tend to burn up. Start by looking into those two possibilites if you have no lights or anything.
