I have a 15 year old aquarite system that was working fine until a few weeks ago. First it showed lower levels of sale (2200) so I added to bags). Despite no warning lights my tests showed no chlorine. The tests also showed very high salt of 4600. I cleaned T cell and upped the percentage but still very little chlorine production. The pool has a T Cell 15 depsite being less than 10,000 gallons. I did replace the system board last year due to a blown resistor. The display board lcd panel is going as well.
Thoughts?
