Hello all. I have a 15k gallon pool with a Hayward Swim Pure salt system. I have had a local pool supply check my water. It all reads good with a 3600 ppm on the salt. (A little high). Display on the control board says 2600 ppm with a solid no flow light. I think the mother board or the flow switch is bad. Any ideas? I am thinking of getting rid of the salt system and going back to a chemical system. (Salt system is 5 years old. It might start going bad soon) Good idea or not?
