My pool started to look a little cloudy last week so I went over to my Hayward SWG Control Panel and saw Low Salt and Check cell were both lit up continuously, I cleaned the cell and no change so I ordered a new cell which arrived tonight I installed it and no change both are still lit up. I also looked over at my heater today and it is showing an "if" code. I was wondering what would be able to cause both issues at the same time or if it was just a coincidence. Both units are Hayward and about 4 years old.
