Last week my dishwasher ran all night, not shutting off until I opened the door. I had to unplug it to reset it it seemed to work fine until today when it stop allowing me to choose any cycle except normal. It also does not run (motor or pump) but the timer will count down.

Sounds like a control board problem.
You may want to try removing power from the unit for 5 minutes or so just to see if it will reset.
You could try cleaning the connections but this is a long shot as a dirty connection should not make it run continuously.
Connector Cleaning / Checking
Unplug the unit
Open it up
Remove the ribbon cable from the keypad to the control board at the control board.
Clean the edge connector.
If it is the type where there is not a connector just the insulation is removed, it can be cleaned with a pencil eraser. Do not use an ink eraser as it is too abrasive.
Check the tracks in the ribbon cable for hairline cracks. A magnifying glass helps here.
Would not hurt to clean the connector on the board. Use electronics contact cleaner or isopropyl alcohol and a tooth brush. Be gentle and do not reconnect till all the solvent evaporates.
Reconnect everything and give it a try.
Thank you so much for your help. One more question, in your answer you said looks like a control board problem - does that mean i need to order both a control and a board?
Thanks Dale
