It could be a variety of things, call the manufacturer, I would hope that the unit is still under warrantee.

I had the same problem, with a brand new unit. I wrote to the distributor, who said that I needed a new control board. They asked me a couple of questions about the unit (to figure out which control board I needed), and sent me a control board at no charge. (Your mileage may vary.) Installation took about 40 minutes with my 6yo helping me (20 minutes without the assistance), and fixed the problem.
FYI, the control board comes with the thermostat permanently attached -- I suspect that it was just the thermostat that needed replacing, but the entire control board goes with it as a single unit.
Final note: The instructions that we were provided for replacing the control board were incomplete in a couple of areas. Again, YMMV. You need to 'figure out' the information that isn't in the instructions in a couple of spots. Not rocket science, but not obvious if you're expecting the instructions to be well written and serve as an effective guide in completing the replacement.

To change your heater display from Celsius to Fahrenheit: press and hold the "down" button and the "enter" buttons simultaneously for 5 seconds and release.

If you can see air swirling around, then there's bound to be water moving around. Otherwise you wouldn't see anything moving. You have a small suction leak somewhere. When you don't have the heater turned on, there's less strain on the pump and therefore less of a suction leak. Assuming your heater has an auto-bypass. Use your garden hose to find the suction leak and patch with silicone or pool putty. Or replace o-rings and gaskets. Check plugs and grease ports, etc.
