There is power to the dishwasher but nothing works no lights

You have to do a bit of troubleshooting with a voltmeter. You need to make sure there is 120 volts at the connection box of the dishwasher. You cannot use a proximity voltage tester, because that doesn't identify the presence of the neutral conductor.

Then make sure that the control board also has 120 volts. Check for fuses inside the control panel. If you have voltage, at the control board, then you need a new control board
