Renee G Oklahoma City , OK March 13, 2016 Appliance: General Electric Dishwasher PDW9900N20BB Ge Dishwasher Pdw9900n20bb: It wouldn't start the electrical panel had started failing from the left and finally got to the start button. How to replace Keypad - Black. Purchased a new electrical panel. I was skeptical as to whether or not a 63 year old (non-mechanically inclined) woman would be able to install it, but didn't have the money to call a repair man. Someone posted some basic instructions online, which I followed. It took me about 45 minutes - basically because I didn't know what I was doing and was very cautious. It was much easier than I expected and I'm thrilled with the results and proud of myself that I could actually do it. 9 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
