We just replaced both the T-Cell 15 and the circuit board - a total of over $1K! It still won't chlorinate. We have the cell tested at the Pool store and it checks fine, and there are no alarms on the control board, it all looks like it's functioning fine. When we super chlorinate, the level reaches about a 1. It should be between 2 and 4.

So it seems that it super chlorinates, but it won't chlorinate the regular cycle. We've done everything, increased the Chlorinate to 100%, increased filter time, cleaned the filter, etc. Does anyone have a suggestion?
