I am working on my in-laws pool at the end of last year their low salt light was red. Since it was still producing chlorine he left it alone and would throw a bag of salt in Every once and awhile. This year upon startup its red again and after doing research I replaced the flow switch. Upon initial start up after replacement the IC20 went through the red green flashing sequence then settled on green salt light. After a few hours the red low salt light retuned. I added some more salt and let it set a few days and rechecked it. It still had a red low salt light but everything else was still green.
When I tested the water there was zero chlorine And the salt level was fine which got me searching again. This was a replacement cell for a original unit with a 3/09 build date and their IC20 only has a small box attached to the wall near the filter. The cell that I’m working with now has a build date of 07/2016 so I’m wondering if it’s a board that’s gone bad as it seems not to be producing chlorine and still has the low salt light While the other lights are green.
