Remove the filters to eliminate them as a cause.
It seems to be working. It ran for quite a few hours and then was flashing again. I reset it and it has ran all night, is now at 97Â° (20hours later)
This is my first HS so I'm not sure but the flow seems really low in circ. mode. There is no visible action in the skimmer and only after removing the stand pipe did I feel some suction when putting my hand on the opening. Is that right? To go along with that thought, there is no venturi action at the Ozone tee. Water actually drips out w/ the pump running. I tried to gently clear with a paper clip but no difference.
Appreciate your thoughts!
