We have a Resilience SWG system with the SCC-25 salt cell. It was installed in 2007 when the pool (14,000 gallons) was built, so this is our 6th season with it. It has functioned perfectly up until recently.
Even though the salt level is fine (I had the water tested) the LEDs on the control box have generally been showing the lowest setting (10%) and now lately showing no LEDs lit up at all. Occasionally the proper salt level is indicated on the LEDs which makes me think it could be a loose connection somewhere.
I cleaned the cell with a diluted muriatic acid solution, which did not seem to make a difference.
Could the control box have gone bad? I'm reluctant to run out and buy a replacement cell if something else is the issue.
