Not to hijack the thread but my control unit for the SWG keeps going to checking cell. This suspends the SWG unit and my on demand acid. When I power off everything it comes back normal but hours later back to checking cell status. Any thoughts?
My SWG went from being stuck on checking cell to now saying its low on salt (when I know its not). Hasn't produced chlorine in days. This is leading me to believe this thing is faulty. Anyone else think the same?
Im not sure if you are dealing with the same "issues" I thought I had with my IC40, but it was reading levels all over the place until my pool water reached 61 degrees. my unit is only 9 months old as well and I thought it went bad already. although the manual states 55 degrees (or something close to that) after doing extensive research and talking with people, it seems the unit doesn't want to work properly until the water temps are above 60. I guess the manufacture also calibrates the until to read accurate salt levels at 77 degrees as well, so you either have to compensate for the values given at the current temps or buy a drop test kit to measure accurate readings of salt levels.
Pentair had an issue with a bunch of bad flow/temp sensors a while back. If your water temp is high enough, I'd say get them to warranty replacement. The sensor is easily replaceable if you can't get it covered under the warranty
