Check side of boat for water streaming out of one of the through hulls. If you do not see that, you don't have water going through the system. My aircon raw water pump and hoses are all accessible from a port located under my mid berth mattress. It could be that your seacock is closed or you need to prime the pump.
It will pump water and run for about 5-10 minutes and you can see the water coming out of the discharge on the side of the boat and then I get the HPF code.
I posted the manual with code setting explanations and trouble shooting tips a while back. Have you used the forum search to look at it. It was pretty helpful.

HPF ... I'm guessing but doesn't this stand for high pressure ... something ... freon, or refrigerant??
Did someone look up that code?
