Kitchenaid Superba Dishwasher (Model No.KUDS24SEBL2) Not Working?

I have an 8 year old KitchenAid Superba Dishwasher that will not work. The Energy Saver Dry, Child Lock, and Rinse Aid Empty lights continually blink. The control panel is of a push button type. I have attempted to turn the Child Lock off by holding the Energy Saver Dry button for 5 seconds, but that does not work. I have held the button for almost a minute. Nothing happens. Is there a type of reset that I can do, or is the switch gone bad. The control panel was replaced by a repair technician 2 weeks ago. Please help.
