Folks. Here's is a summary of the system, situation and symptoms:
- AquaRite controller and T-15 salt cell circa 2009
- 25,000 Gallon pool in northeast (Nova Scotia). Pool usually open 3 months with pump on 12 hour on/off cycle.
- 500lbs of salt at opening about a month ago. Same amount as previous years.
- SWG worked fine for three weeks then started tripping off on "High Salt" but I'm suspect of the accuracy of this reading
While generating here are the readings:
- 4,800
- 77
- 23.6V
- 7.65A
- 21%
- 4,900
- AL-3
- r 1.40
After it trips and not generating
- 4,800
- 77
- 31.1V
- 0.00A
- 21%
- 0
- AL-3
- r 1.40
The inrush current limiter/thermistor has a tiny what appears to be a burn mark on the top edge. As this thermistor is a known problem with these units, I suspect this may be all or part of the problem. I measured the temp of it while generating and it was 131C/268F. I have a replacement coming tomorrow but something tells me there's something else wrong. My hunch is that the salt cell has reached the end of it's useful life. My question is whether a worn salt cell could yield an incorrect salt reading. I couldn't find any posts that indicate such.
Appreciate any guidance anyone has to offer.
Regards,
Bill
