Your tech data sheet should be located behind the bottom access panel (the black panel on the bottom of the dishwasher) near your floor. This is the one that I think is for your model: applianceblog.com/mainforums/attachments/665-14743n512-tech-sheet-w10751166-rev-c-pdf.38363/
If you can't open it from that link, scroll a little bit down this page for the pdf file: applianceblog.com/mainforums/threads/665-14743n512-kenmore-elite-intermittent-failures.66342/
From the tech sheet, this is how to reset your dishwasher: To quickly advance through customer cycles, invoke the Rapid Advance mode by pressing HIGH TEMP - HEATED DRY - HIGH TEMP - HEATED DRY, after starting the cycle. Then, press START/RESUME to advance through cycle intervals. (Press SMART DRY in place of HEATED DRY.)
