Dishwasher troubleshooting

I would need a little more info, but I will try to help for now. First, check the breaker to make sure it didn’t pop. Then check the power to the unit to make sure it is getting 110 volts at the terminal. If all power is good, look at the simple things like the “child lock” isn’t on. In some models, if the door latch is broken won’t allow the unit to pick a cycle, so make sure the latch is sitting properly. These are the basic things the check first before calling in a repair place that can assess if a fuse or the panel has blown.
