Dishwasher just continues to wash

This unit continues to run in the wash cycle. The only way to get it to go into next cycle is manually. I am thinking it is a control issue, but notice there are several control boards and not sure which one may be the culprit to my problem. Any help would be appreciated. :o

Hi.

Based on the info you provided the control board is bad.

For the serial number starting from 10 through 18 use part number 99003160.
For 19 and up - part number 12002709.

Here are the breakdown diagrams and http://www.appliancepartspros.com/partsearch/model.aspx?model_id=5177628

Thank you. Post the results.
