I have a one year old Pool Pilot Digital Salt System that is currently not producing chlorine. My chlorine levels have been variable for the last few months and require frequent adjustments to the percentage on the control box (check the chlorine, level is low, up the percentage, check the chlorine, level is low, up the percentage, repeat, repeat). I started noticing algae in the pool in January. I was told by the local pool store that I needed to shock the pool monthly, which I have been doing. This month I shocked the pool and noticed algae again about two weeks later. The pool store recommended shock, an algae pack and then an additional shock in one week. I did the initial shock/algae treatment two days ago and tested my water today to make sure the chlorine level was where it should be. To my surprise NO chlorine whatsoever. I put it in Boost mode and now, twelve hours later I still have no measurable chlorine in the pool. I didn't expect it to be at a high level but, after running for that period of time at 100% I would expect at least a minor increase.
The acid and stabilizer levels are good. I cleaned the filter and removed a minor amount of scale from the cell.
There are several issues possible...
One, the Pool Pilot was not able to produce an adequate level of chlorine on level 1 when it was brand new in 75 degree weather. It seemed to work sufficiently at level 2. Could I actually need to move it up to level 3 after only one year? Is this normal or could there have been something wrong with the cell from the start?
Two, the current salt level is too high (3900) - could this be causing the chlorinator to stop functioning?
I am really puzzled at this point.
