GE GSD2000G00WW - won't drain

When I cycle the control switch, it looks like the solenoid activates correctly. I removed the drain line and checked that it was not clogged. When cycling the control switch while viewing the underside of the dishwasher, I can see the solenoid pulling down. I can hear water spraying into the dishwasher. To the right of the solenoid, I can see a round grid that looks like a vent to a motor. As I cycle the control switch, the "fins" that show through the vent will move just a little but they never rotate. Am I looking at the motor?
