After it removes all the air it will probably just look clear. I don't think you have a problem there if water is running into skimmer and coming out of return jets.

If this is a problem only when the air temp out side is cooler than normal and your water temp is low, then the unit is performing correctly. The heatpump is having trouble performing with low ambient air temp because when the temp gets to low the coil will ice up. You may also have a bad defrost sensor (coil temp sensor).

Make sure your water filters are clean and if you have an external by-pass, make sure it is not open. High Ref Pressure is normally caused when the refrigerant is not cooled off by the pool water circulating thru the heat exchanger. If your filter pump is not circulating enough water (normally around 40gpm) in the system then you will trip the high pressure sensor. If the HP sensor trips without the compressor engaging the try replacing the sensor.

You may only need a defrost sensor. Unfortunately the issue you are having can also be caused by low refrigerant and or a bad board. If your unit has a TXV valve that has stopped working properly you could develop this issue aswell. Make sure the fan is operating normally and your evap coil is clean. I would start with the sensor first and if it turns out to be good then call an HVAC pro, otherwise you could spend a lot of money trying to fix the wrong problem.
