Step by Step

Top

Step 1

The Hayward Aqua Rite Salt Chlorine Generator displays a total of 9 diagnostic parameters that are accessed by pushing the Diagnostic button sequentially. The default display is the Average Salt Level.  If the button is not pushed for 30 seconds, the display will revert back to this salt display.

Step 2

Push 1, POOL TEMPERATURE - When you push the diagnostic button the first time, the display will show you the pool water temperature as it is measured inside the cell. The Temperature is displayed in Fahrenheit or Celsius. The default unit is Fahrenheit. If you want to change the Temperature units of measurement to the English version of Celsius, see our guide on "How to Change the Units of Measurement on an Aqua Rite SCG".

Step 3

Push 2, CELL VOLTAGE - The Cell Voltage is typically 22.0 to 25.0 Volts when chlorine is being generated, otherwise it is 30 to 35 Volts.

Step 4

Push 3, CELL AMPERAGE - The cell's average amperage when chlorine is being generated varies with the size of cell installed: T-15 is 3.1 to 8.0 amps; T-9 is 2.3 to 6.7 amps; T-5 is 1.9 to 5.7 amps; and t-3 is 1.3 to 4.5 amps. When the cell is not generating chlorine the amperage is 0. If the amperage is below the applicable range, check the salt level and inspect and clean the cell.

Step 5

Push 4, DESIRED OUTPUT % - The percent of time the Cell in ON. Run from "0P" to "100P" depending on the knob position.

Step 6

Push 5, INSTANT SALT LEVEL - The salt level that the System is calculating during the chlorination cycle. A "-" symbol is place in front of the number to distinguish it from the Average Salt Level.  Measured in ppm or grams/Liter depending on units of measure setting. To change units of measure,  see our guide on "How to Change the Units of Measurement on an Aqua Rite SCG".

Step 7

Push 6, PROGRAM CODE - This identifies the product. "AL-0" signifies "Aqua Rite"

Step 8

Push 7, MAIN CIRCUIT BOARD REVISION - This signifies the software revision level in the Main Circuit Board [currently r-1.59].

Step 9

Push 8, CELL SIZE - The Aqua Rite SCG uses one of 4 Cell sizes - t-15, t-9, t-5, or t-3. The Cell size displayed here has to match the installed cell to ensure proper operation including salt calculation. The cell install in this system is t-3. If this displayed and installed Cell size do not match, see our guide on "How To Change the Displayed Cell Size on an Aqua Rite SCG".

Step 10

Push 9, AVERAGE SALT LEVEL (DEFAULT) - On the 9th push of the Diagnostic Button, the display returns to the default display value, "Average Salt Level". The Average Salt Level reading is a sliding window of Instant Salt Level readings sampled every 3 hours or so. The Average Salt Level should track fairly close to the Instant Salt Level but occasionally, after some events like adding salt or changing cells, the two levels are considerably out of sync. When this happens, the Average Salt Level must be recalibrated to the Instant Salt Level, See our guide on "How To Recalibrate the Salt Level on a Hayward Aqua Rite" for instructions on recalibration.

Step 11

"HI" SALT DISPLAY - The higher the salt level, the higher the amperage that is drawn by the Aqua Rite SCG.  If the three larger size cells draw over 10 Amps or the smallest cell draw over 8 amps, the SCG will shut down to prevent itself from overheating. Upon shutting down the display will show "HI". The "High Salt" LED will also illuminate to signal that the pool's salt level must be reduced. See our guide on "How To Reduce the Salt Level In Your Pool" for more information.

Step 12

RESET INSPECT CELL TIMER - An internal timer is set inside the Aqua Rite SCG to remind you to inspect and clean the Cell. If the "Inspect Cell" LED is flashing and the salt level is above 2700 ppm, the 500 hour timer has been exceeded. Inspect / clean the cell and then hold down the Diagnostic Button for 3-5 seconds to reset the timer for another 500 hours.

Step 13

LED LIGHTS - For information on reading LED lights on the Aqua Rite SCG, see our guide on "How To Troubleshoot a Hayward Aqua Rite"

I have a Hayward Aqualite t-9 SCG. Salt generator is 2 years old and recently cleaned. Check salt level light (solid) comes on. Instant salt reads 300….not the 3000+ required. Salt level has been tested to be around 3000 range. Have tried to recalibrate instant salt yet reading with (-) in front of it never changes from 300. Replaced main mother board and salt sensor Still getting same issue after several days of running. Any help would be much appreciated.

Have you checked if your control is set to display US Standard or Metric? How to Change the Units of Measurement on an Aqua Rite SCG

Thank you for your response! Yes, I did try that. I changed the U of M and still get an incorrect reading. T-9 cell is set correctly along with 1.59 software version and AL-0.

The two most likely suspects are the Main PCB or the cell. Because you have already replaced the board, I'd say the cell is bad. You can rule out the board by checking the amperage in both polarities. To do this, press the diagnostics button three times. This should bring up the amperage. Write that number down. To switch the polarity, move the main switch from Auto to Off and back to Auto. That will give you the amperage in the second polarity. If either one of those readings is 0, the board needs to be replaced.

My cell is a TCELL940-W and my system is running version 1.59. After a power outage, I was getting no chlorine and the "check salt" and "check cell" lights were both on. The instant salt reading kept saying 700 when the actual salt reading, verified 3 ways, is 3000. What is the appropriate t setting, t3, t5, t9, or t15?
 Reply

InyoPools Product Specialist  Posted: 8/20/2021 

Which cell size do you have? The answer would be the one you'd choose. If you have a T15 cell, pick the T15, and so on.

My display says "cold" instead of the salt level. The water temperature is over 89? however. The first number that appears when I push the diagnostics button is 0. What could cause this issue?
 Reply

InyoPools Product Specialist  Posted: 8/4/2021 

The water temperature sensor is in the cell, you can try cleaning the TurboCell and if that doesn't clear the error you will need to replace the cell.

When I press the diagnostic button 9 times the LCD does not display the average salt reading (default display). If the diagnostic button is not pushed pushed for 30 seconds the display does not revert back to the average salt reading (default display). Help with this would be very much appreciated. Thank you.

Have you tried recalibrating the average salt level? Have you recently replaced the cell or added new salt? What are the cell's voltage and amperage readings in the diagnostic menu?

If the screen is damaged, then you need to replace the whole AquaRite display board - GLX-PCB-DSP or you need to get out the soldering iron to install a new LCD screen.

Brand new install no salt in pool yet but the average salt level shows 2800. Instant salt level is 0. Also I do not have the number 8 diagnostic which shows what chlorinator cell I should have. It is a T5 but i don't have the option to check from the control box.. Model W3AQ-TROL-RJ- TL.
 Reply

InyoPools Product Specialist  Posted: 6/4/2021 

Are you waiting for the instant salt level to stabilize after you bring it up?  From Hayward's troubleshooting guide, "Press the ‘Diagnostics’ button 5 times, this will bring up the instant salt reading. The instant salt reading will start as -0. It will then fluctuate. Wait for the number to stabilize."This guide is not going to be completely applicable to your unit as this is for an AquaRite and you have an AquaTrol.

Does the aqua rite unit, depending on the output percentage, shut the cell on and off , or just raise or lower the voltage to generate the percentage set. I have a t-3 that I checked and noticed the voltage at 0 then I turned the knob higher and the cell clicked on.
 Reply

InyoPools Product Specialist  Posted: 5/13/2021 

I believe the voltage is cut in between periods of chlorination. When you turned the cell up, what was the cell's voltage reading?

What is the ideal salt level supposed to be? I am 3100.
 Reply

My diagnostic light does not light up.
 Reply

InyoPools Product Specialist  Posted: 2/8/2021 

There is no diagnostic light; there is a diagnostic button. Are you referring to either the No Flow, Check Salt, High Salt, or Inspect cell lights? If the cell is making chlorine and those lights aren't flashing then there isn't an issue.

My output % display does not match the dial number. For example, to get the output to 65, the dial has to be turned up to 90. I can set the display at 60 and a few days later it will read something different. Is there a fix?

The display board likely needs to be replaced. Before you do that, have you made sure the knob isn't loose?If you need it, the AquaRite display board can be found here: Hayward AquaRite Display PCB (OEM) - GLX-PCB-DSP

My salt level reading said cold this morning...how do I get it back to tell me what the salt level is?
 Reply

InyoPools Product Specialist  Posted: 12/14/2020 

You can try resetting or recalibrating the cell to see if it will provide a reading before it shows COLD again. Or you can test the water using salt test strips to determine the pool's salinity level.Or wait until it warms up again so the cell can turn on and operate normally. If you are in an area where temps stay around 50 degrees Fahrenheit or lower for most of the winter, the salt level is not that vital. Temps below 50-60 degrees pretty much halt algae growth, so there's not much need for chlorine.

Inspect cell and check salt light is on always ... I changed the cell to the same t-9 made sure the salt level is correct In the pool but the system still won’t recalibrate, it’s giving me a lower reading of 1800 instead of 3400 were the salt level really is. I’ve tried to select cell type but there is no options coming up on the display to select the cell type. Is the board outdated should I replace circuit board next.?

How old is your AquaRite control box? The original boxes (up until 2010, I think) only accepted a TCELL15. If you have an older model, your control is not set up to switch cell types or even recognize different cells. In that case, to get the new cell to work, you need to replace the Hayward AquaRite Main PCB (OEM) - GLX-PCB-RITE

Hello, I currently have a Hayward aquarite system in which my T-Cell 9 is failing. Can I upgrade it to the T-Cell 15? in which I can produce more chlorine at less amount of work on the cell? Would this cause a problem? or it's not recommended. thanks for your feedback.
 Reply

InyoPools Product Specialist  Posted: 10/6/2020 

Yes, you can upgrade to the TCELL15. You just need to make sure you adjust the cell type in the control panel's settings menu. The cell will have a higher chlorine output, so you won't need to operate the generator at that high of a percentage. At what percentage you will need to run, the cell will vary on chlorine demand.

The salt level says 2.5. What does that mean? It was reading low salt and I added 2 bags yesterday
 Reply

InyoPools Product Specialist  Posted: 9/2/2020 

it appears you have the panel set for grams/Liter and not parts per million (ppm). The salt level that the System is calculating during the chlorination cycle. A "-" symbol is place in front of the number to distinguish it from the Average Salt Level.  Measured in ppm or grams/Liter depending on units of measure setting. To change units of measure,  see our guide on "How to Change the Units of Measurement on an Aqua Rite SCG"

I was getting the message add salt, inspect cell. So my cell was 5 years old so replaced it, still getting the same message. I had the PCB board totally inspected everything is working properly. Any ideas?
 Reply

InyoPools Product Specialist  Posted: 7/3/2019 

My first step would have been to test the salinity level at a local pool store to confirm whether or not it is wrong. If the salinity level checks out, makes sure the correct cell type is selected, as that will affect the readings on the display.

Hi, to add to my last comment. When I first press the button to get to the polarity it will stay on zero and not calculate. However, if I start off by switching the auto, off , auto the polarity will count down for both sides. I didn't know if that was normal. It seems like it wants me to switch from auto, off, auto first before it will show a reading other than zero but if I just open the box and go to polarity it will stay at zero. Thank you
