This just started happening yesterday on my just over a year old SJ-40. The unit powers on, but the power LED steadily blinks. It used to power on, pause a moment, then LEDs would all light to my desired output level, then a moment later the cell would start bubbling.
With the SWG on for hours, nothing changes, only just blinks. I found in troubleshooting manuals it says "The cell isn't getting power" is what a blinking power LED means. I can visually verify that as the cell is clear, only the occasional bubble flowing from the filter tells me there's water in it at all. Where normally there's a cloudy mess of bubbles formed from the fins of the cell.
Seems like a similar issue as Cmasty mentioned below on this forum, although he didn't mention the blinking LED.
Also in the troubleshooting manual it suggests raising the desired power level to Super CL mode, then holding the + button to request more chlorine. This did get the 1/2 polarity LEDs to cycle yesterday, then the power LED went solid and the cell began working. However today this trick has not yielded the same result. The 1/2 polarity does cycle, but then it stops and the power LED continues to blink.
Temperature is 85 degrees, salt level is between 7 and 7.2 on the salt test strips. (Meaning somewhere between 4k and 4.4k PPM salt) PH is 7.5. I'll run numbers on TA and CH later, I seem to recall my TA being higher than expected after a new liner/fresh city water this season. But it was 220 last I checked, and I did a LSI calculation which put my pool at +0.22. I think that suggested I'm leaning toward having scaling problems, but overall pretty good. The fins on the salt cell look pristine though.
