I just purchased a new T15 cell for my 18X36 in-ground vinyl liner pool due to the low salt and inspect cell lights coming on after a few seconds of sliding the switch to AUTO. The pool is balanced and I still have the same results. Now the first reading is 700 all the rest seem to be correct Temp and so on. I did inspect the board and didn't see any burnt spots and was told by Goldline that since I got 5 seasons out of my original T15 cell it was time to replace it. After reading the manual 3 times I still can't find a possible solution to my issue. Has anyone else had this issue? I have search the forum but couldn't find anybody with this same issue. I am have read many post on this site and wish I had found this site before I purchased a pool. I think I might have joined a swim club instead. Thank you in advance for any suggestions you might have.
