Salt level is reading very low

Jump to latest Follow Reply
The cell temperature sensor seems to be accurate and the salinity calculation takes the temperature into consideration.

I don't think that the temperature is an issue in this case. It might make some difference but I don't think that it's going to be a significant difference.
 
The intellichlor is known to have a defective temperature sensor.

The intellichlor has a separate salinity sensor whereas the Aquarite uses the performance of the cell to determine salinity.

If you increase the salinity enough, you can make the cell work again for a little while.

You can also change the cell size to a T-9 in the configuration menu to make it work again.

The cell metal plates are probably deteriorating and beginning to disintegrate. At some point, metal pieces will begin to break loose and go downstream from the cell.

Ok, I think that it's just a worn out cell. I would recommend a regular Hayward T-15.

Make sure that the cell is a 3 year warranty model and not a 1 year model.

They should be the same cell other than the warranty.

So I bought the new cell and installed it. The good news is my red light that indicates a low salt level went away. Initially it read there was 3100 salt level but now it’s showing a 4700 salt level. I haven’t take the water to the local pool store to have it checked but there is no way the salt level should be that high. The last time I had it checked it was 3400 and I haven’t added a bag of salt since.

If you got a new T-15 and the cell is set to T15 in the settings, the salinity is probably accurate.

Test the salinity with a K-1766 to confirm.

I reset the system and when it started back up it started out reading 3100 and I thought things were good. Then it jumped to 4000 so I did what you said and had the water checked. I took a sample to the local pool store and they tested everything. It said my salt level was indeed 4000. So I thought my system was fine after all. Since yesterday the level is now up to 4800. What would cause the reading to keep going up. I haven’t added anything to it and I’ve changed the cell so that isn’t the issue.

The salinity is probably accurate. I would go by what it says. As long as the amps stay below 8.0, you're fine.

As the water temperature rises, the amps will increase.

So, you should slowly work the salinity down as the water temperature rises such that the amps stay below 8.0.

I recommend that you get a K-1766 salt test kit.
