We have a GE dishwasher, model number GDF520PGJ2WW. The start light is blinking and beeping 3 beeps every 2 minutes or so. I have tried turning off the power for 10 minutes to reset it, but that doesn't seem to be working. What can I try to get the dishwasher to run a cycle and work?

As I understand, the dishwasher is working, the problem is with the light? Have you solved the problem? I'll better call to support and explain the problem or go to the local shop where you can find such a dishwasher and ask their consultants to help you. Say, that you want to buy this dishwasher but heard about such a problem. I often do so. They will find tons of arguments about how to fix this) I am joking. Call to support. Maybe the problem with electronic or power surge took place.
