Tested the old motor with a multi-meter. Determined it was not getting proper voltage when it was supposed to be running. Removed old pump by disconnecting two terminals and drain line, then removing tabs that hold it to the dishwasher. Looked up new pump using model #. It arrived in 2 days and took me less than and hour to diagnose, remove and replace the pump, test and replace access panel on bottom. $45!! Appliance repair people wanted $175!! Saved me $130.
