Whirlpool Duet door locked and no lights on

I have a Whirlpool Duet front loading washing machine. It ran through a cycle, and now the door is locked and there is no power at the unit. I have switched outlets and checked the breaker. All are good. I have unplugged the washer and pressed the power and start buttons for 5 seconds and then plugged it back in. This did not do anything. I have removed the top and released the door to remove the clothes. Is there an easy way to check to see if it is the control board, or should I check something else?
