Hello, I am having a rather frustrating experience with my Circupool SJ-55 and am wondering if anyone on here has any other ideas on what can be done. I had the unit for 2 years and it worked pretty well until this year. It now fails to produce any chlorine at all. A few months ago I noticed various warning lights come on and the chlorine level was subpar/nonexistent so I called Circupool and they asked me to send the unit in. They replaced the circuit boards and sent me a new salt cell. After hooking it back up, I still get an error signal intermittently, but even when there are no error lights the unit fails to produce any chlorine. The chlorine level in the pool was 0 after running the pump for 10 hours with the salt cell at SuperCL Mode. There are also no bubbles present within the cell when the pump is running to indicate production of any chlorine. My pH is 7.6, salt level is 4750, and CYA is 50. I have called Circupool several times and they suggested turning on the salt cell 30 minutes after the pump comes on to mitigate any problems with air bubbles, checking the connection between the salt cell and the control unit, and also making sure the power is ok to the unit. I have done all of this and everything seems to be in order and nothing has worked. It does seem like the salt cell is not getting any electricity to convert the salt to chlorine, but I'm not sure what else I can do. Thank you.
