Won't run

My Dishwasher Won’t Run. Nothing On The Panel Lights Up Except High Temp Dimmly Lights When You Push A Button. Just Replaced Control Board But Nothing Has Changed. Any Ideas?

Start where the power starts: Is the machine getting 120VAC at the connection or outlet? If so, you’ll need to check the door switch for its proper function. This can be done safely after you unplug/disconnect the dishwasher.
