Dishwasher does not finish cycle

The wash cycle works but then stops. Not sure if the rinse cycle is working but When it is done washing (or rinsing) the indicators lights go off. Normally it would indicate drying or complete. The dishwasher can not be restarted for a while either. After the wash cycle is complete all lights die for about 30 minutes until the dishwasher is restarted. Could it be the control board out? Thanks in advance.

Very likely the problem is a bad control board.
