Dishwasher lights

This is an older dishwasher that has worked fine. After it ran last night the “clean” light flashes and will not reset. I have shut off the electricity and when turned back on it is the same. I have tried all the other buttons it will not start or do anything now. The switch on the door looks OK. Any suggestions?

Here is the tech sheet with info on this problem
