Can anyone help me with what is going on? My IC 40 reports good flow but the red light (low salt) is on. The pool temperature is 65 degrees right now, but the red light remains on when I switch to spa mode and heat the jacuzzi. Is the IC 40 malfunctioning? I am concerned about low chlorine production since the machine is perceiving low salt levels. I had my pool tested for its salinity and it is nearly ideal at 3435 ppm. Thank you for any suggestions.
