Jandy AquaPure Error Codes

Whenever you make a high- value purchase, you never expect anything to go wrong with it, at least not right away. As consumers we assume that the more expensive a product is, the better the quality, and therefore the longer the lifespan. The logic seems legit to me. The only downside to a product failing further down the line (as opposed to earlier) is sometimes you can’t find the manual or any matching paper work to help you either with the warranty or to diagnose the issue.

It becomes especially difficult if the product, like the Jandy AquaPure Chlorine Generator, only displays an error code, but not necessarily what the error code means nor solutions to the problem. If you purchased the unit a year ago, it’s quite possible you may have misplaced or thrown out the manual. How will you diagnose the issue then?

Here at INYO Pools we come across this situation a lot. Customers call with error codes, but they are unsure what they actually mean or even how to proceed to fix the issue. With that in mind, we wanted to create an easier way for homeowners to diagnose their Jandy AquaPure. Let’s explore the codes, their meanings, and possible solutions together.

You know what’s frustrating for any pool owner? It is to come home from a long day at work only to discover that one of the pieces of your pool equipment is malfunctioning. You know what’s even more frustrating? Not knowing what the issue is. This happens to a lot of pool owners who may own the Jandy AquaPure Chlorine Generator. It’s not a testimonial of how bad the unit is,( Jandy is a great manufacturer), but rather how negligent, here I include myself, we can be with product manuals and documents. Who actually reads those, anyway? So, which error code is your Jandy unit displaying?

LEVEL 1 SERVICE CODES

Level 1 service codes are more common than level 2 codes and can typically be troubleshooted by the homeowner  and a Jandy technical representative. Although you can troubleshoot and determine the issue yourself, we do not recommend that you replace any internal parts if you do not feel comfortable.

Utilize the chart below to help identify the error code, the possible cause, and corrective action. We offer several how to guides that should assist you in diagnosing issues as well as replacing certain parts.

[table id=21 /]

LEVEL 2 SERVICE CODES

Level 2 service codes are less common but can be more difficult to diagnose as some issues may cause more than one service code to appear. Some error codes, though, will require a licensed professional for proper troubleshooting.

[table id=22 /]

Although the charts should help narrow down the root to the issue on your Jandy AquaPure unit, it may not completely answer all your questions or concerns. If you still have questions, please do not hesitate to give us a call at 877-372-6038 and if we don’t have an answer, we will get you in contact with someone who will.

    I have an error service light that pops up on occasion.
    It appears I have been adding too much salt.
    What is the best solution?

  2. Gary Avatar

    Did you get my question re the service 145 light?

    1. Matthew Simmons Avatar

      It’s listed in the article:

      145 High Salinity (above 4.0 gpl)
      1. Recalibrate salt reading.
      2. Backwash your filter if a DE filter is installed.
      3. Partially drain your pool and dilute with fresh water until salinity level returns to 3.0.

    How do you do a diagnostic test on the board?

    1. Matthew Simmons Avatar

      Are you looking for a general diagnosis procedure, or are you attempting to diagnose something specific?

      Jandy also provides the AquaPure manual with troubleshooting section.

        I have code 194 and 125 , I cleaned the cells with muriatic acid but still not working, do I need to replace the whole unit or just fix the inside ?

        1. Matthew Simmons Avatar

          The cell needs to be replaced.

    I am getting an error reading of 170. I have replaced the front circuit board but it continues. What next?

    1. Matthew Simmons Avatar

      The article mentions that in the first section:

      170 – Possible Front board service condition or unit not correctly wired to 115 VAC – 1. Typically caused by low AC voltage from back board. Check the transformer and back board.
      2. Troubleshoot with Jandy or a licensed professional.

      1. Hershel Avatar

        I had the same problem. I replaced the entire APUREM Power Center. Still getting same message.

  5. Gary Avatar

    I have an aqua pure 1400. Getting error codes 125-194. I cleaned the cell and still getting codes. I performed the following; The voltage going to the cell is 16 VDC. I also checked all the input voltage at the test points and +/- a few volts all the AC voltage is fine. I’m of the opinion that the board is bad considering the low DC voltage. Also, what amperage should be pulling on the cell?
    Thank you,
    Gary

    1. Matthew Simmons Avatar

      Gary, the guide is pretty clear that you would need to replace the cell, see below.

      194 -Cell current is 85% lower than desired and cell voltage above 19V. – Generates code 125- The cell is dirty or needs replacement

      Since you have already cleaned the cell, the replacement is the next step. This is the Jandy AquaPure Troubleshooting Guide, it lists all the specifics you should need.

      1. Tony Avatar

        I’m getting 125 code however the salt cell in new last season and it was cleaned and stored with pool service company .
        Also 154 code is coming up .I can’t find what that is

        1. Matthew Simmons Avatar

          It sounds like you need to replace the trisensor if the cell is new and has been cleaner. I have checked the manual a couple of times, but there is no mention of a 154 error code on the AquaPure system. The only mention of the number 154 in the manual is the amount of salt needed for the specific pool size and current salinity levels.

    I have an older aquapure 1400 system. I had constant error code of 170. I ordered a new flow sensor and installed and it fixed that problem. Now I am getting an intermittent code 120 problem but the flow and cell lights (Green) are On. I read that Code 120 is forward low cell current. How can I determine if the system is producing chlorine or not. I didn’t check the DC CABLE to the cell and it appears to be OK. What else should I check?

  7. George Avatar

    I reseated the DC cable on the cell and no longer having code 120 errors. The flow and cell on lights are lit but I do think the cell is producing any chlorine. One thing I noticed is the salinity is reading 2.4 but the salt reads 3200 at the pool store.

    1. Matthew Simmons Avatar

      Going by the Jandy AquaPure owner’s manual, the suggested next step is: “Remove and clean flow/temp/salinity sensor contacts. Check flow/temp/salinity sensor cable for damage. See Section 6.4. Verify salinity with Myron “L” meter calibrated for NaCl, titration test units, or other salt meters. Please be aware that salt test strips have a large variance in readings (400 – 800 ppm)”

    I have an HH code, it says that means – Input has exceeded Maximum Range.

    Is there a fix to this?

    1. Matthew Simmons Avatar

      AquaPure’s owner manual states that the HH means the following: If a reading of HH appears, the salinity is above 4.5 to 6.5 gpl (depending on pool temperature) and is too high to measure correctly (at normal temperatures). Maintain Salinity between 3.0 and 3.5 gpl.

      Take a water sample to a local pool store for testing. If it confirms the high salt, then you will have to drain and fill a portion of water. If your salt level is in normal ranges, then it is probably a bad sensor that needs replacing.

    My aqua pure from 2009 beeps every minute. The arrive light is on. I do not want to spend the money it will cost to replace anything currently. The buttons on the outside box no longer work, so I can’t silence it that way. I don’t want to shut off the pump. I just want to disconnect the beeping sound. The flow senor wires don’t shut off the beeping. What wire is the disconnect? Thanks

    1. Matthew Simmons Avatar

      I do not know, but it sounds like you have a bunch of issues with that unit and that beeping is just letting you know. You may want to call the manufacturer, who would have more idea on the circuitry of the unit.

      And, why don’t you just turn it off for the season and get some chlorine tablets and a float to finish out the pool season?

    Hello, I just replaced AquaPure 1400, sensor and cable and after install I am getting error code 194. From the comments above, this only happens when a cell is bad or needs to be replaced. However, mine is brand new and clean. Any thoughts? Could it be something else like the board or the program letter (currently its set to Program B like my old one)? Open to try things and ideas. Thanks in advance!

    1. Matthew Simmons Avatar

      The 194 fault code is referring to low voltage, that can be an issue with a board or an issue with the power cable or power supply. I do not have much in terms of troubleshooting guides when it comes to the Jandy Aquapure. You may want to try TroubleFreePool.com’s forum or contact Jandy’s tech support line at 800-822-7933.

    I just replaced my Jandy Aquapure 1400 cell (only) because I was getting codes 125 and 194. It was suggested that I replace the cell, which I did. Now 24 hours after I replaced the cell, I get code 172 and 180. What is the problem?

    1. Matthew Simmons Avatar

      To quote the article: 180 – Heating sensor element not heating. w/ code 172- Flow sensor service

    2. John D Avatar

      Hi Jim
      The same thing happened with my system
      Can you let me know what you did to fix it?

  12. Steve Lash Avatar

    My system is displaying ” test cell ” while running. No error number associated with this message. I have cleaned the cell and the message returns. I replaced the cell about 6 months ago so it is in good working order. Could this be a logic problem with the main board?

    1. Matthew Simmons Avatar

      What are the chlorine levels in your pool? Are they in normal ranges?

    I have a zodiac nature 2 fusion soft. On start up I have flow but display continually clashes between bo and 30%. Doing it for over an hour. Any ideas.

    1. Brad Avatar

      Sorted itself out after a couple of hours. The keys finally started responding and I was able to turn off boost. Strange.

    2. Matthew Simmons Avatar

      I googled the Fusion Soft owner’s manual and the code means: bo – Boost – In “Boost” mode unit will operate at 100% production for 24 run time hours.

      It doesn’t list anything about the flashing percentage.

    We have been having issues since pool opening the our Jandy saltwater chlorinator. 120 has been the main code we have been getting. We had Our pool come out and clean the chlorinator to no avail. I just replaced the chlorinator with a Jandy PLC 700, and put in new wiring and sensor. I am still receiving the 120 code error. Do you have any idea what we can do? Thank you.

    1. Matthew Simmons Avatar

      Unfortunately, I don’t know where your 120-code is so stubborn. you might want to give a call to Jandy to see if they can troubleshoot it with you over the phone.

      If you get an answer, please let us know what you find out.

    I get 110 code when I open my Jandy saltwater chlorinator, do you have any idea what I should do?

    1. Matthew Simmons Avatar

      The AquaPure codebook starts at 120. Are you sure you have the Jandy AquaPure?

    2. Jason H. -Brentwood Avatar

      I have the AquaPure 1400 unit and may have an answer. Jandy tech support suggested it may be actually an error code 170 versus 110. I noticed on my LCD it’s switched between 110 and OU%. The error code 170 is a front circuit board fault and could be related to the top pixel not being illuminated for the 1”1”0 and O”U”%. Hope this helps as I couldn’t find any information on 110 error codes.

    My chlormatic 3 is showing error code 110. I can’t find what this means anywhere!

    1. Matthew Simmons Avatar

      Codes for the Chlormatic III start at 120 and go up from there. I do not see a code 110

      1.  Avatar

        i also have a code 110 and for some reason it isn’t in the manual.
        it says production at 15% and cell reversing and it beeps and says 110

        1. Matthew Simmons Avatar

          Everything I have read on the subject just shows that 110 is the type of cell. It could mean to replace the cell.

    I have a jandy. And its Reading (stand by).. at all times no error code.. is that normal???

    1. Matthew Simmons Avatar

      It shouldn’t say standby when the unit is producing chlorine. Which Jandy system do you have? Is it an AquaPure, AquaPure Ei or other?

  18. Rafael Avatar

    I can’t read the codes , I have a yellow light only showing on the screen.

  19. Brent Avatar

    Im getting 121 code regularly. Was getting a 120 also. I’ve done the acid clean, but the code did not go away. I’m thinking it’s time to replace (for the third time!), but I’d like to test the DC cable, as the manual suggests. Do you have the procedure for testing the DC cable?

  20. Shawn C. Avatar

    I have a Jandy AquaPure 1400 and it’s giving me a 182/175 code. I have gone through all the trouble shooting and everything is within parameters but do not know what the “air lock condition” means. Air in the system…? I also get no reading when I depress the “salinity” button. Do I just need a new flow sensor. Mine is ~4years old. Thank you ahead of time.

  21. Adrian Avatar

    Hello, I have a aqua pure 1400 with the code 170 I have cleaned the trisensor. That didn’t help, I replaced it with a used sensor from my pool guy. The one I put in was the black epoxy version with a adapter cable ( small circuit board) I get the same code 170. I am wondering if it is still could be the sensor, is there anything I can do to confirm what could be the fault. Thanks

  22. Sandy J Avatar

    I have an Aquapure EI, it keeps saying “Test Cell”, I have replace with a new cell pod and still says the same thing…my salt & chlorine levels ( had them tested at pool store) are good as I was using chlorine tabs for backup until I got new pod installed. Any other ideas?

    1. Matthew Simmons Avatar

      There is not much info on the Ei models for troubleshooting available to us as Jandy removed their goods from the web. You may want to contact them directly to see if they can provide further assistance.

      It sounds like you have a bad board, but to figure out which one you would need to do some deep troubleshooting using this guide: AquaPure Troubleshoot Guide

  24. bk Avatar

    Hello. My inside panel says “no flow”. I’ve cleaned the basket and it went off. That was yesterday, but now today it shows “no flow” again. I unplugged the sensor and cleaned the plugs. “no flow” went away for a few minutes but now back on. There are NO error codes on the small board. Tomorrow I will clean the filters but am starting to think the sensor is bad…again. Replaced it 2 years ago. Thoughts?

    1. Matthew Simmons Avatar

      I presume it is another faulty flow switch. Unfortunately, the pool industry has yet to design a stout flow switch that can hold up for as long as the control box and cell do.

    I have AqualinkRS4, i lost power last night for few min, from than my pump and spa is a coming on automatically every few min, I could i stop and reset my pump for filter program for daily 8 hrs. dont need to program Spa, also let you know outside unit showing light LP.Please your advoce.

      This is a completely different control than your basic AquaPure we are discussing in this guide. The more intricate automation systems like the AquaLink should be troubleshot with the manufacturer Jandy.

    Hi. I got the 145 error on my Jandy Salt generator. I know it means Salt level is too high, so I am draining a bit and adding fresh water, but what does recalibrate the salt reading mean in your comments above?

    1. Matthew Simmons Avatar

      It resets the sensor; consider it like unplugging, then plugging in your router when your internet is shoddy.

      How to reset the salinity level on an AquaPure system:

      aquapure salinity  level recalibration

      1.  Avatar

        I tried these steps because I am also getting error code 145. The salinity was high in our pool but the pool store reading and manual readings are much lower than what the system is reading. When I hold down the “salinity” button it only beeps 2X. Any suggestions on what to do next?

        1. Matthew Simmons Avatar

          You may need a new cell if you’ve cleaned the cell, recalibrated the unit, and the salt reading is still significantly off the pool store test results. If your cell is over three years old, it may be time for a new one.

    showing a code of 124 jandy 1400 cell and aqua pure 700

    1. Matthew Simmons Avatar

      The owner’s manual I found says the 124 error code means “Higher than normal current to cell.” After that, they do not go any further into diagnosing the problem than “Contact a qualified service representative.” You may want to try checking youtube for any troubleshooting guides and the like.

    I am getting the 120 code on a handy nature2 fusion soft. it had build up, took 2 times to clean at lest what I can see. When I turn it on it starts ok then faults 120 again. How can I tell if its a dc wire issue or cell needs to be replaced?

    Unit is 5 or 6 years old.

    1. Matthew Simmons Avatar

      There are no solid how-tos for diagnosing the DC cable; the manual only says, “check DC cable.” I am not surprised by the lack of online guides because these are lovely pieces of machinery, but they are expensive and overkill for most pools.

      the manual says the 120 code is “Low current in the forward section of Cell.” The specs for the voltage and amp output for the Fusion Soft 700 are 22-30 VDC @ 3 AMPS maximum, and the Fusion Soft1400 is 22-30 VDC @ 6 AMPS maximum. If you have a multimeter and feel comfortable using it, test the cable leads.

    Our display is not working and the system is not making chlorine, however, we cannot see a code. What do you suggest?

    1. Matthew Simmons Avatar

      First, I’d make sure the system is receiving power from the breaker. If the power is reaching the control, then I would try troubleshooting the PC boards; the steps for doing so can be found starting on page 15 Jandy AquaPure Error Codes

    I am getting an HH code when I press temperature and 2 dashes pressing salinity.

    1. Matthew Simmons Avatar

      From the manual:

      Salinity is displayed along with the gpl (grams per liter) indicator, when
      the Salinity button is depressed. If a reading of HH appears, the salinity
      is above 4.5 to 6.5 gpl (depending on pool temperature) and is too high to
      measure correctly (at normal temperatures). Maintain Salinity between
      3.0 and 3.5 gpl. See pages 18 through 21.
