dishwasher flashing lights

I have a 3 year old kitchen aid dishwasher, I put it through a wash cycle and at the end or close to the end of the cycle the normal wash and sani rinse buttons started flashing. I tried to cancel it and then the cancel button is flashing. I unplugged it to see if it would reset and it does not. I was thinking it was the control panel. What do you think?:confused:

          Thanks, Cathy

Never mind, I saw your posting about stuck buttons and I noticed one of them seemed stuck so I pushed on it a couple of times and it loosened up! All is back to normal…Thanks any way!
