DU945PWSQ0 Whirlpool Dishwasher Won't restart

[gbsk]

I opened up the dishwasher early in the cycle to put a couple of things in the dishwasher that a member of the family had in another room.  The lights were on the panel and pushed Start again like I always do.  This time the dishwasher did not restart.  I cannot unplug the dishwasher since  the plug is behind it.  I turned the breaker off for a few minutes and tried again.  It still would not start again and I turned the breaker off again and still the same result.  Any suggestion are welcome.
