Called our contracted home maintenance company. Their repair guy looked at it and told us we needed a new control board and it would be nearly $400. We declined, thinking we would be buying a new DW. Then we watched a couple of repair videos on replacing the control board and it seemed like something I could do. Ordered the part, watched the video again and then replaced it in under 45 minutes. Biggest challenge was the position you need to be in to replace it, which is lying on the floor working under the DW door. For saving $300+, I can handle that.
