Yesterday I cleaned the cell and made sure salt levels were OK. I also tested the chlorine level at the time of writing this post and it is OK as well. Previous owner told me cell is fairly new and motherboard was recently changed.

Correct cell type t-15 is set

Only value that is off is Total Alkalinity because I used some faulty test strips and ended up messing up TA

New pool owner here, so please let me know if you need more information from me. Thanks!

Welcome to TFP.

@JamesW will be by soon with instructions on the diagnostic procedure.

Do you have a salt test kit like the Taylor K-1766 or TF-100 Salt Test to independently test the pool salinity? If not, you need to get it to know what your real salt level is.

For AquaRite, move the switch from auto to off and check all of the readings.

Move the switch back to auto and recheck the readings.

Move the switch to off for a minute and then back to auto and recheck the readings.

Switching the unit off and then back on makes the unit reverse polarity.

Report all readings.

What are the first seven characters of the cell and box serial numbers?

What is the actual salinity and how are you measuring it?

What is the T-cell size?

Is the T-cell size set correctly in settings?

To get the performance percentage of the cell in each polarity, divide the instant salinity reading in each polarity by the actual salinity reading.

For example, if the instant reading is 3,300 ppm and the actual salinity reading is 3,300 ppm, then the salt cell is working at 100%.

However, if the actual salinity was 3,800 ppm, then the performance percentage is 86.8%.

Anything over 75% is acceptable.

At75%, or lower, in either polarity, it's time to consider replacing the cell.

The instant salinity in both polarities should be about the same (+/- about 200 ppm).

You need to be really sure about the actual salinity reading.

You need to use a K-1766 salt test kit or a calibrated meter.

K-1766 Taylor Salt Test

Note that ProLogic, AquaLogic and AquaPlus use the Hayward T Cell.

However, the procedure to get the diagnostic readings is different.

Here is the procedure for ProLogic, AquaLogic and AquaPlus:

Go to the diagnostic screen, note the readings and then press the + button to reverse the polarity.

When the new numbers appear, see what they are.

Then, press + again and note the new readings.

Hi James, I'm sorry, I havent had a chance to do the proper analysis you suggested.
However I noticed that in the morning, when the pump is scheduled to start, it starts with the Inspect Cell and Low Salt lights on. When I switch it to OFF and back to AUTO, the problem disappears.
Any suggestions?

Is your SWG powered off when the pump is OFF?

And is only powered on after the pump is running?
