Dishwasher starts but won't cycle

Jenn-Air JDB4000AWB. Just successfully replaced drain pump, now the machine will not run through its cycle. Up until the drain pump problem, the machine ran through its cycles and cleaned normally. Symptoms:
Upon pressing START, fills for 85 seconds, quiet for 10 seconds, hums quietly 3 times for ~3 seconds each over a period of 50 seconds then the lights go off, does not drain. There were no rotational, grinding or other noises during this period. After this, when START and CANCEL are pressed, the machine successfully drains.
