Kristy W Vacaville , CA September 05, 2020 Appliance: Model MD87749AWW2 The start and cancel button would not function or illuminate. I removed six screws with a torx driver. Unclipped the door latch from the old control panel and installed it on the new control panel. Unclipped the control board from the old control panel and installed it on the new panel. Reinstalled the new panel to the dishwasher with the six screws. This was a simple process and took a total of about 10 minutes. The hardest part was figuring out how the control board unclips from the panel. I'm a 67 year old woman and I fixed my own dishwasher! Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
