Circupool Core-55 System error light blinking

[poolschpool]

Hello,
I have a 2.5-year-old Core-55 system that was bought in Sept 2020. Since last week the System error light has been blinking on it and the chlorine levels have gone down in my pool.

I have tried cleaning the salt cell in Muriatic acid and have also tried to clean the connectors between the salt cell and the control module.

Any idea what is going on.

Have you tested the salinity of your pool water?

the chlorine levels have gone down in my pool.

Get them back up and keep them there with liquid chlorine until you get it figure out. Do it today.

What pump do you have? What speed are you running it at?
When was your filter last cleaned?

Too low a pump RPM and/or a dirty filter will prevent the SWG from working correctly.
