SWG incorrectly reading zero

[JamesW]

The salinity is calculated from the production of chlorine.

With no production of chlorine, the salinity is calculated to be 0.

Determining Salinity.​

The AquaRite uses the performance of the cell to determine salinity. For each cell (T-3, T-5, T-9 OR T-15), Hayward knows the performance of a properly functioning cell at each temperature and salinity combination. The higher the salinity and/or water temperature, the higher the performance (chlorine output).

To get the performance of the cell, divide the instant salinity by the actual salinity. If the ratio is less than 75%, it's time for a new cell. For example, 2,000 (instant salinity) ÷ 3,600 (measured salinity with a test kit)=56%. Check the cell and clean it if necessary. If that doesn't work, it's time for a new cell.

So here's a picture of the guts of my SWG... It does have a thermistor but it looked to be in good shape. When I was digging into it I remembered I had an old salt cell and decided to hook it up... The old one is actually producing chlorine again... I'm not sure how long so the culprit like you guys recommended this definitely the salt cell.

Here are my new numbers... Do you see anything of note?

Change the cell type to T-9.

 

[Jschway]

Change the cell type to T-9.

Done!
I remember doing this in the past. What is the reason?

 

[JamesW]

Recheck all readings in both polarities.

The actual salt reading is 2400

Actual from where?

 

[JamesW]

Tested salt with the Taylor kit reading at 3,000.

This is the actual salinity reading.

The cell is different in different polarities, which indicates a bad cell.

 

[Jschway]

Actual from where?

We've had a lot of rain! I use a Taylor kit.
