No matter what I do I can't get my FC or CH up. When I 1st started up the unit for our 2nd season for the first week or so it said check flow. I called autopilot and they gave a work order number for service ($30). It took me two weeks of calling to finally get the service guy out and he knew less about than I did (message had stopped by then anyway). He tested my water and said I was low on CYA. I agree I was a little low, so i accepted his answer. Three weeks later and I just finished running my pump in boost for 24 hours and still no CH or FC. I took a sample to the local pool store two weeks ago and my water was fine. My PH was little high and they confirmed I had very little Cholorine in the water. I dropped it with Muratic Acid and added shock . The cholorine came up for a few days and went back. Just finished running my pump in boost for 24 hours and still no cholorine. The cell looks fine.
I have a gunite pool with @ 19,000 gallons.
Auto Pilot DIGI-220 with SC-48 cell running power level 2 at 68%.
My readings are:
Total hardness= 250
Total Chlorine=0 to .5
Please help. I checked the cell and it looks fine. This is only my second season to use it.
I am pulling correct amps (confirmed by service guy) and my salt is around 3200ppm
