Maybe you are one of the very few lucky people experiencing an "infant failure" of a significant component. I would verify you are delivering 12v
to the pump. If the switch is in "store" the system won't deliver 12v
to the pump. If you verify you are delivering 12v
to the pump, then stop by the most convenient Airstream dealer and make a warranty claim. They should take care of you right away.
