"Hi,

Here’s the complete 8524517-Tech-Sheet.pdf

Scroll down the the section entitled RAPID ADVANCE SERVICE FEATURE AND DIAGNOSTICS CYCLES (on lower right side of p.2 to see how to get into the diagnostic mode).

Also under DISHWASHER CIRCUITS > WASH / RINSE it has the wiring schematic for the wash motor circuit that may be worth checking. Disconnect the power and use an Ohmmeter to check for continuity between the connection points between the different components and also the pump motor windings. The connection through the electronic control board can only be done with the power connected by using a voltmeter. Be safety aware if you decide to try this as there is lethal AC voltage testing involved. If you don’t know how to test safely then don’t do it!"
