I just installed my 24' round saltwater above ground pool 2 weeks ago. I balanced the chemicals and got them all within range, salt os at 3400 and tried to start my Hayward Salt and Swim ABG 3c, but after calibrating, the problem detected light comes one and the #4 LED light is blinking. I called Hayward and followed all their suggestions. I have taken the Salt cell out, turned it 180 degrees, had it tested at the pool store, its good, I have unplugged and replaced the control panel. The water is 60°. I'm at a loss on what to do next, as the warranty center does not currently have any panels in stock. Does anyone have a suggestion before I unmount this control panel and take it into the store and wait for a replacement? I really don't want to have to do that if I don't have to.
