Robert L Gahanna , OH October 09, 2015 The "normal wash" light was blinking and would not go off Installed a new Control Panel. I tried to switch out the mother board first, but the light continues to blink. Then I installed the old motherboard on the new control panel and the light stopped flashing and the dishwasher worked.
