RJ45+ Generate LED quick light green flashes. Nothing else is indicated. I cycle power to fix temporarily CircuPool RJ-PLUS Series Salt Chlorine Generators - Owner Resources RJ PLUS Series

RJ45+ Generate LED quick light green flashes. Nothing else is indicated. No other LEDs are on and the cell does not fix itself.

The only fix I have found is to cycle power to the unit. Then it will work for a few days to a couple of weeks, then it happens again.

I've cleaned the cell, but that hasn't stopped the problem. Temp of water is mid 70's, salinity is around 3500.

If your CircuPool RJ-PLUS Series controller has a flashing "generate" light, this is typically accompanied by message indicating low or high water temperature, due to the system is getting a signal that the water temperature is outside of operational range. If the water is not actually too cold or too hot, then something might be occurring with the temperature sensor inside of the cell. Follow instructions in the manual to remove the cell from the cell from the plumbing and clean it, paying close attention that there are no solids or debris inside of the upper portion of the cell near where the cord connects. If after cleaning the cell and restarting the system, the system still gets a flashing "generate" light or a water temperature message, then damage may have occurred to the item. At that point, please reach out to our support team and call or create a support ticket online.
