My T-CELL-15 has stopped generating CL. Yesterday, I ran it for 10 hours at 100%, and the CL level did not change.
The cell is only a year old. I’ve had it tested at two different pool stores and it passed at both. I’ve cleaned the cell. The Aquarite diagnostics indicate 25.7 volts (a little high) and 5.97 amps while running.
Chemistry: ph = 7.5, TA = 80, CYA = 70, salt = 3300, phosphates < 100. Pool temp = 66, outside temp = 68 and partially cloudy.
I tried an overnight FC loss test (with an FAS test kit) and did not lose any CL. I measure 0 CC.
I’m out of things to try. Any ideas would be appreciated.
