Hayward Aqua Rite Error Code Guide

In my professional and personal experience, I have come to the conclusion that hardly anyone keeps owner’s manuals around. Don’t worry, this isn’t a dig at you but for some reason no one ever thinks he/she will need it again. Why? I am not certain. It is safe to say that somewhere down the line, the product will fail. And once it fails, the owner’s manual should be one of your first go-to documents for resources.

Sometimes, it’s not about the initial need for the manual, but for issues that spring up down the line. Pool owners are a group of consumers who I think need to keep all their manuals around, especially if you own any type of automation or salt chlorine system. The cool thing about salt systems is that when an error occurs, it typically gives you an error warning or code. That code gives customers a better idea of what the problem is and how to address the issue. But where are those codes and explanations usually? Take a wild guess.

The owner’s manual.

Hayward’s AquaRite Salt Chlorine Generator is one of the most popular lines on the market today. It is one of the easiest ways for you to sanitize your pool. Although I won’t get into too many details on how great the product is, you can read our customer reviews to get unfiltered opinions about it.

Still, one thing I do commend Hayward for is their simplistic error code guide. Compared to a lot of others on the market, going through their manual and troubleshooting guide was as customer friendly as you are going to get. But what good is a manual if customers don’t keep it?

Hayward Aqua Rite

Capture41The Hayward AquaRite system was strategic in the design in the sense that there aren’t too many variations of error codes programmed into their system. Unlike the Jandy AquaPure unit, which displays a number that then corresponds to a particular error, the Hayward Aqua Rite is simplistic in nature. It tells you the source of the issue.

If you take a look at the picture on the left, there are only 4 different error functions: No Flow, Check Salt, High Salt, and Inspect Cell. Although there may be several reasons for the error code to appear, having only 4 possibilities is great odds for a pool owner. It also makes it very clear to the pool owner what the issue might be once they venture out to the system. Let’s explore the different Hayward Aqua Rite error codes, what they mean, and how you can get rid of them.

Check Salt & Inspect Cell

Seeing as this is a salt chlorine generator, one of the most frequent error codes you will see will have to do with your salt checksaltlevels or the cell where the salt is produced. And because one directly affects the other, both lights will appear when there is an error concerning the salt levels.  Let’s dig a little deeper.

I. ‘Check Salt’ Light & ‘Inspect Cell’ Light Flash Together

When both these lights flash together, it means your salt level is between 2500 ppm and2600 ppm. At this moment chlorine is still being produced, however your salt levels are dwindling. Keep in mind, your ideal salt level should read 3200 ppm. Your AquaRite system may be working efficiently and your pool may be clear at the moment, but in a week or so, it may not be the case anymore.

Remedies:

  1. Independently verify the salt levels in your swimming pool. You can utilize one of our at home testing kits, or you can get your water tested at your local pool store.
  2. Once your water has been tested, add salt to your pool to bring your levels back to the recommended 3200 ppm. You can review how to add salt on our site, as well.
  3. Inspect and clean cell if, necessary.

II. ‘Check Salt’ Light & ‘Insect Cell’ Light Stays On

If both the Check Salt and the Inspect Cell light stays on that means no chlorine is being produced at this time. That is a big “uh-oh” for any pool owner. It also means your salt level fell below 2300 ppm. Yikes! Both lights will also stay on if the control is set to the wrong turbo cell type, or if the cell is unplugged.

Remedies: 

  1. Independently verify the salt levels in your swimming pool. You can utilize one of our at home testing kits, or you can get your water tested at your local pool store.
  2. Once your water has been tested, add salt to your pool to bring your levels back to the recommended 3200 ppm. You can review how to add salt on our site. If your independent testing shows your salt levels are correct, but your system is showing something different, you may need to recalibrate your Aqua Rite unit.
  3. Inspect and clean cell, if necessary.
  4. Verify if the control is set to the correct turbo cell.

III. Only ‘Inspect Cell’ Light Flashes

If the ‘Inspect Cell’ light flashes by itself, it is an early indication that the cell life is coming to an end. Each cell is equipped with 500 operational hours and requires a manual reset once it expires.

Remedies

  1. To reset the cell, hold down the ‘Diagnostic’ button for 3-5 seconds.

High Salt

The ‘High Salt’ light is exactly what it says There is literally a higher recommended amount of salt in your pool. Your unit will detect and alert this to the owner.

highsaltI. ‘High Salt’ Light Stays On

The ‘High Salt’ light will stay on for several reasons including: cell amperage is above the maximum limit, the control is set to the wrong turbo cell, or you simply have too much salt in your pool. The LCD display will read “HI”.

Remedies

  1. Independently verify the salt levels in your swimming pool. You can utilize one of our at home testing kits, or you can get your water tested at your local pool store.
  2. Once your water has been tested and the reading is too high, reduce the levels of salt in your pool to bring your levels back to the recommended 3200 ppm.
  3. Verify if the control is set to the correct turbo cell.
  4. Verify cell amperage to ensure it is not above the maximum limit for your model. Check below for the maximum current amps before the unit shuts down.

No Flow

The ‘No Flow’ light is an indication that there is something funny going on with the flow in your piping or the flow switch itself. If there is an issue with the flow, the ‘No Flow’ light will flash up to 60 seconds at start up. If none of the below remedies solves your issue, you may need to replace your flow switch.

Remedies

  1. If a LED is flashing, wait 60 seconds after starting the filter pump. Check for possible disruption inside of the flow T. yupInstallation requires 12 inches of straight pipe before the flow switch. There should be no elbow after the flow switch.
  2. If a LED is ON, check to see if the flow switch was installed correctly. The arrows at the top of the hex nut should point in the direction of the water flow. (Your flow switch requires a minimum flow rate of 11 GPMs  to stay consistently closed.
  3. Check the flow switch for damaged or cut wires.

Low/High Cell Temperature

Although there isn’t an error setting for temperature on the control, the LCD monitor will let you know if your water is either too hot or too cold for standard operation. The cell’s operating temperature range for the cell is 50F to 140F. The output is scaled back to 20% at 60F and output completely stops at 50F.

The LCD display will read COLD when the water temperature is below 50F.

The LCD display will read HOT when the water temperature is above 140F.

No manual is more efficient than the technical support provided by the manufacturer. The manual allows you to get familiar with your system and put your DIY skills to the test. If at any point you do not feel comfortable or simply just don’t know what to do, definitely give us a call. If it’s something that we can’t solve, we will put you in contact with a rep from Hayward.

    I have a new T-15 Salt Generator . I know it has well over 500 hours on it . Have not seen the light come up to inspect cell .Hayward Goldline AQR15 AquaRite Electronic Salt Chlorination System for In-Ground Pools , 40,000-Gallon Cell . What do you suggest ?

    1. Matthew Simmons Avatar

      If the cell is still producing chlorine, I wouldn’t worry about it. if it is a new cell, it would have to be run really hard right out of the gates for it to reach 500 hours already. The 500 hours is hours producing chlorine, not installed on the pool. So if you have your system set for 50% production and you run your pump for 8 hours a day; your cell would only have 4 hours of service on the counter for that24-hour period.

    HI,
    We had a new salt unit installed last summer. We just opened our pool and the no flow alarm is on, and nothing we have tried has gotten it to turn off. What could be causing the no flow alarm?

    1. Matthew Simmons Avatar

      Have you checked the filter’s pressure to make sure there isn’t an issue with the pump/filter system instead of the flow sensor?

    2. grant Avatar

      do you have a flow sensor separate from the system…a wire that is plugged in…if so it might of gotten turned, and is the generator in the right way

  3. Mike Avatar

    I have a new t-15 salt cell, and a new circuit board. Display is ON, generating is ON, display says 3200 for salt level. But, during the day, and when the pump shuts down at the end of the day, the CHECK SALT light comes on, and the INSPECT CELL light comes on, The display says “SLo.” The green button next to GENERATING is still on. What does SLo mean? Salt low? (it is not). When the pool pump comes on the next morning, andn during the day, the system will continue to display these readings until I turn the system off, then back on. That clears the check salt and check cell light. Green GENERATING light stays on, and obviously green POWER light is on. The pool technician that came out this AM thinks its the water…he thinks there is too much salt. But I had it tested a couple of times, and it came out 3200. Any words of wisdom?

    1. Matthew Simmons Avatar

      This is a reply we received from a Hayward tech:

      The reported error would be very dependent on the control that is powering the T-Cell. The error displayed “SLo” is not programmed into an AquaRite, AquaTrol, or AquaRite Pro. I have encountered control boxes that were AquaRites which had a knock-off replacement board displaying some unusual codes.

    Just put on new cell T-15 and the inspect cell light is still
    On?

  5. Cassie Avatar

    We had a new salt cell system put in in October. It kept saying inspect cell and check salt and they replaced it. We opened our pool and it says the same thing. When I try to calibrate it starts at 2600 and goes down. The salt level is 3200. There is no way the cell needs cleaned because it was only used for 2 weeks before we closed the pool. Is it possible to have a second defective cell?

    Hello, I get ”Cold” on display but no led light (even pump stop still no led light). I cleaned the cell temp sensor still the same. Pool temp is at 64 F. My cell is about 8 years old, is cell the end of life?

    1. Matthew Simmons Avatar

      8 years is definitely at the high end of the lifespan of a salt cell. Those cells normally last 3-5 years.

      It sounds time for a new cell, let your old one go to that great big pool in the sky.

    Hello. I changed the cell from t-3 to a t-9 since the system was not generating chroline. I confirmed it reads t-9 in the panel. Now it reads 4000ppm of salt and is not indicating high salt. I have tried to calibrate it several times but getting the same output. I had test the water and no chroline is detected. It’s the cell or the main pcb?

    1. Matthew Simmons Avatar

      Have you had your water tested by a local pool store? If so, please post the results including CYA levels. The steps for troubleshooting issues like this hinge on an accurate salinity level.

    Cannot get the ‘inspect cell’ light to go off…steady on, not blinking. I have cleaned the cell multiple times with the mixture of Mauriac acid ( 10 mins, then 20 mins, then 10 again) flushed with clean water, unplugged the cell, checked to ensure the control was still set for the t15. Nothing is working. This is an entire new system – 7 months old…..

    1. Matthew Simmons Avatar

      The AquaRite is programmed to display the “inspect cell” after 500 hours of cell use. This ensures a regular inspection/cleaning takes place. To reset the check cell light, you will need to hold the Diagnostic button for 3-seconds, then release.

      If the check cell light comes back, then you may have a faulty cell. Since the cell is only 7-months old it should definitely be covered under warranty, and replaceable.

      1. Cynthia Avatar

        Thanks Matthew! Now….without any other ‘cleaning”, the “inspect” cell was flashing and I can reset it, but it would only stay off a couple of hours. This morning the reading is 2900 (preparing for warm weather and just added more salt Sunday) – the light is no longer ‘on’ nor ‘flashing’. It does worry me that there is still something wrong. I do have a local pool supply retailer who has suggested I bring in the cell to test, so I guess I will before the warranty expires – just in case. Thanks for the quick response!

      2. MTO Avatar

        Replaced my cell recently because inspect cell and check salt light was on. It was working fine today but when I got home inspect cell light was blinking yellow, salt read 2800, both power and generating was green. Cell is T15. Thanks

  9. Tony Avatar

    Replaced t15 cell cause GENERATING LIGHT was off. Brand new cell generating light still wont turn on only power all the reading work except the t cell # one.

      Were you unable to select “T15” on the display when you installed the new cell?

      What is the temperature where you live? Also, have you had your salt level tested yet? Salt generators do not work in temps 65-degrees or colder. But usually there is a “COLD” error code that pops up. High or low salt levels could be the problem, but the display lights should illuminate. The display board may be shot.

      Is the cell not producing any chlorine?

  10. Daniel Avatar

    So the display says Cold! So what do you do? It doesn’t say what to do or you just don’t do anything??

      This is the excerpt from the article:

      Although there isn’t an error setting for temperature on the control, the LCD monitor will let you know if your water is either too hot or too cold for standard operation. The cell’s operating temperature range for the cell is 50F to 140F. The output is scaled back to 20% at 60F and output completely stops at 50F.

      With it currently being winter you’ll just have to wait a few months for it to warm up or use your pool heater to up the temp. Since it is so cold, your pool’s chlorine need is severely lowered, and algae can’t grow in temps below 50 degrees Fahrenheit. But if you want to play it on the safe side, get a chlorine float to supplement the chlorine.

      If your water is not at that temperature cold range then you may need to clean your cell.
