Hi, we are having an issue with our Hayward aqua plus not registering the salt level correctly. It is registering at 1000 ppm. We have a separate salt tester that has the salt at 3450 PPM. The salt cell is right at 3 years old. This is now causing our pool to turn green because it is not allowing the salt cell to turn on. It worked two weeks ago and now it is no longer working after some large amounts of rain over a week ago. I have purchased a replacement flow switch to try. However, I’m not sure if our automation system is going out. Is there a way to test this ? Or is it as simple as buying a new salt cell? The salt cell has been cleaned thoroughly this week and that did not change the reading on the system.

This will be our 9th summer to swim in the pool and nothing really has been replaced other than the original salt cell. Everything has worked perfectly fine up until until now. Of course, our pool builder is no longer in business so we can’t reach out there for assistance. Thanks in advance. IMG_7143.jpeg

How old is the cell?

What is the serial number on the cell?

The salt level on Hayward systems is a calculated number that declines as the cell wears.

Good chance your cell needs replacement.
 
Cell was replaced in April 2022. It is an aftermarket cell. Thing is it was reading the levels just fine a week or so ago and now it won’t even turn the SWG on. Thanks for your response.
That can be the way aftermarket cells fail.
 
Thanks again for your help.
