I have a 33k gallon, gunite pool. I have the Aquarite, with a T15 cell. I opened my pool a couple of weeks ago, added 1/4 total water volume and appropriate amount of NaCl, things were good. Salt read in the 3200 ppm range. I have had it open a couple of weeks, but didnt run SWG due to cold water temp, just added bleach.
This week, i turned the SWG back on and things were good. I vacuumed the pool, and left the SWG on, which i usually dont. Afterward, I had the message warning, "check cell" and "check salt". I cleaned the cell, which I did when I opened the pool, and put back on. Salt was reading initially at 400 ppm, and then 800. I call Hayward, the suggested getting digital NaCl analysis, I did it came in at 2600. So, the pool store gave me a new T15. I put it on, started it up, and again its reading -900 ppm, and within a couple of minutes the lights came on for 1) check cell and 2) check salt.
The pool stool said I did not have to reprogram the unit for the new cell, because I am swapping a T15 for a T15. I cant help but think it has something to do with reprograming the box or having it recognize that its a T15 cell?
Any suggestions would be helpful.
Im wondering if I need to reset the box somehow, or if there is something else potentially going on. Any suggestions would be helpful.
