The dishwasher will not turn on. When you switch from heavy to normal to light cleaning buttons the lights for heavy and light will light up but not the normal one. If you push the button to go from heavy to normal and the light for normal doesn't light up- and then with it in this mode you push the start button you can barely see a really dim light on the normal light. Some of the other buttons will not work either. The unlock/lock button, plus a couple more that have to do with the rinses and drier part. I am inclined to think the control board but I don't know how much the button panel and associated harness have to do with it. Any help would be greatly appreciated. Thank you.
