Maytag dishwasher blinking

Question

My maytag dishwasher model 665.15974992 lck on light is blinking. When I pulled the kick panel off and foung the repair guide it says it is doing this because one ore more buttons is stuck, but doesn't say how to unstuck them. I have tried pushing all the buttons and even slamming the door whith no avail. im am the daughter of a maytag repairman and determined to fix tis. Any suggestions? Thanks! Judy
