Having started the season well with my Aquarite system, I now find the Superchlor. function not working. All of the other parameters appear normal. When I turn up the % knob, I do hear the relay kick in. Indicated voltage and amperage appear to be in normal range while apparently active. No fault lights lit, and NaCl =3100.

The board and cell (T15) were replaced Spring of 2019, INYO parts. All was well until past week.
