GLX-PCB-MAIN - Very low salt error

[spierscw]

My Hayward system recently started giving a "very low salt" error and won't generate chlorine any more. I've checked the salt level independently and have changed the cell. When looking at the diagnostic menu, I see 32v, but 0 amps and 0 chlorine. I've also confirmed that the correct cell is selected.

Does anyone have any ideas, short of replacing the board?

At current water temps of probably 50 or below, the salt cell won't generate at all. Without it generating it won't give an accurate salt reading. You can just turn it off until your water temp rises above 50 in the spring and then see what it reports.

Be sure to use liquid chlorine while the cell isn’t producing.

What is the water temperature?

If it is above 50F, try this:

Go to the Diagnostics menu, first page and click on "+". What do you see after the countdown?

These boards have a habit of burning out solder joints underneath the K1 relay. So if the water temperature is high enough and the current still reads zero after resetting the board, then it is likely a solder issue.

My water temp is 64, so I pulled the board and found burnt joints on K2. I was able to touch them up and it's all working now. I'm no soldering pro, so if the problem comes back, I'll take the board to a TV repair shop to see if they can make a more permanent repair.

Thanks for your help.
