A few months back, we noticed that whenever we try to wash anything on the "casual" cycle the time displayed changed to a much longer time. Last week the same thing happened to "delicate" mode, increasing the time to one hour and seven minutes. After finding squat on the net on this topic, I came to the conclusion that the control board might be the culprit. But which one? When I look up the parts manual, photo shows two control boards, (137035240 and 137208012) one black unit and a larger white one. I have no idea which one to order, but both parts are over $100. Can anyone help?
