Pentair Intellichlor IC-40
I have a ~4.5 year old Pentair intellichlor IC40 that started having a green blinking light recently. (I’d estimate around 10,000hrs of use) I confirmed salt content was still near 3600 ppm. I removed and did the acid clean per the manual, with no evidence of scale bubbling so only left the acid solution in the cell less than a minute.

Is there any other things to diagnose what’s wrong with the cell or do I need to replace it? Based on the manual, this appears to be typical life span of a cell.

If replacement is recommended, I’d be interested in input on some other options like an apex p40 or apex p60.

10,000 hours and blinking CELL light means the cell is depleted and needs replacement.
