My salt cell (Hayward turbo) is staying that chlorinator is off due to low salt. The diagnostic reading is attached. It is reading at 0000 ppm salt levels and negative power. I have A salt test kit and it is showing 3000 ppm so i know I’m ok there. I replaced The cell only a year ago. I pulled it out to clean it and it looked fine. I unplugged it and plugged it back in. Flow is on and seems good. Thoughts? Thanks.
