My IC20 started flashing green indicating high salt. I tested it a few times and my salt level is approximately 3000ppm. I cleaned the cell and it still flashes. I've searched and can't seem to find any info on this. My CYA is 70, FC is 2-4ppm and PH 7.6.
When I turn on the cell the green light flashes rapidly (it used to alternate green and red but I'm wondering if the red LED died) for a few minutes and then changes to flashing slowly. Is there some other thing that could cause the sensor to read high salt? Do I need to call the pool builder and get it serviced?
