I have a Pentair IC20 SWCG. During the past month, the readout on my EasyTouch control panel indicated "0 ppm" of salt. However, my test kit showed a salt level of 3,400 ppm. By rebooting the system, the SWCG apparently starting "talking" with the EasyTouch & indicated the proper salt level. Given my limited knowledge, this seemed to point toward a faulty thermistor/flow switch.
Yesterday I shut down the system to replace a pvc fitting to my heater. After I powered on the system, the SWCG displayed a red flow light & the salt level lights blinked back & forth between red & green.
Since all system valves are open & the filters have been recently cleaned, it doesn't appear that there is a water flow issue. (However, I will remove the SWCG cell & inspect it for any blockage). Again, this seems to point toward a faulty thermistor/flow switch. As a side note, I did notice that, in spite of an indication of "0 ppm" on the EasyTouch control panel, the status displayed "OK; No Errors".
Three questions: (1) Is the most likely problem a faulty thermistor/flow switch? (2) If indeed that is the problem, can I assume that the SWCG is still generating chlorine? (3) Is the flow switch (SWCG mfg. on 11/24/2015) a 3- or 4-wire type?
