Dishwasher operation/repair

I can’t change the cycle selections. We bought our house used so I don’t have a manual. Per the sticker on the dishwasher I pushed button # 3 but now I can only get # 3 to be a solid or flashing light and can’t seem to select any cycles. Can anyone tell me what to do?

The first thing I would do is unplug the dishwasher for a few minutes and then plug it back. Sometime it helps to eliminate the problem.

If it did not work, then perform the troubleshooting according to the service manual.
