Jandy Aquapure Pro Series question

Why are you saying it is starting to fail? What warning lights/errors are you getting?
 
No warning lights, just low chlorine production despite cleaning it. It's at 50% at the moment and barely keeping FC above 1.5.

FC 1.8
CC 0
CYA 60
pH 7.8
TA 70
CH 350
Salt 3400ppm

We're in Texas, so I know some of the chlorine can be lost to sunlight, but last year, the highest I had to run it at was 25% when it was going to get heavy use.
 
What does your water look like?
I would suggest raising your FC to 10 ppm and doing a Overnight Chlorine Loss Test tonight.
SWCG rarely slow down in FC production, they either make it or they do not. I suspect you have algae.
