GE Dishwasher GDT535PSM5SS keeps beeping

Randomly just started happening today- every time we press start the dishwasher will start for a minute or two and then just start beeping in sets of three. I have reseated the door latch and verified that the dishwasher is registering the door as "closed" when it is in fact closed. This leads me to believe it has to be some sort of controller board? Any thoughts?

Look on page 13 first to see if its DEMO mode.
