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.

Code NumberPossible CauseCorrective Action
120Low current in forward direction to the cell.1. Clean or replace cell if necessary
2. Check DC cord
121Low current in reverse direction to cell.1. Clean or replace cell if necessary
2. Check DC cord
123Extremely low current to cell1. Clean cell if necessary
2. Check DC cord.
124Higher than normal current to cell1. This is an indication of a bad back board.
2. Troubleshoot with Jandy or a licensed professional.
125Cell needs to be cleaned.1. Troubleshoot your tri-sensor to ensure it is working properly.
2. Clean or replace cell if necessary.
126Low current in forward direction and VAC input voltage below 100/200 VAC1. Check input voltage, transformer, and back board voltages.
2. Troubleshoot with Jandy or a licensed professional.
127Low current in reverse direction and VAC input voltage
below 100/200 VAC
1. Check input voltage, transformer, and back board voltages.
2. Troubleshoot with Jandy or a licensed professional.
144Low Salinity (below 2.0 gpl)1. Adding salt to your swimming pool
2. Add salt to pool to achieve 3.0 gpl
145High 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.
170Possible Front board service condition or unit not correctly wired to 115 VAC1. Typically caused by low AC voltage from back board. Check the transformer and back board.
2. Troubleshoot with Jandy or a licensed professional.
171Possible backboard service condition1. Indication of a faulty board.
2. Troubleshoot with Jandy or a licensed professional.
172Indicates a flow tri sensor service or flow sensor is
unplugged.
1. Clean the flow sensor, check for damage, and replace if necessary.
2. Perform diagnostic test on board to ensure the board isn't faulty.
3. If not the board, the culprit is more than likely the sensor.
4. How To Change a Jandy AquaPure Tri-Sensor
173Low VAC input voltage and on board power supply is
not regulated or unit not correctly wired.
1. Unit may be wired to improper AC voltage.
2. Check for correct voltage.
174Pool temperature is too high for operation of AquaPure1. Flow/ Salinity sensor indicates water temperature at sensor above 108 F. Reduce your water temperature.
2. Troubleshoot with Jandy or a licensed professional.
175Flow sensor air lock condition or very low salinity1. Verify proper flow/temp/salinity sensor was installed properly.
2. Check salinity. Add if necessary.

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.

Code NumberPossible CauseOther Codes It May Generate
180Heating sensor element not heating.Generates code 172- Flow sensor service
181Flow sensor temperature- sensor failure.Generates code 172- Flow sensor service
182Salinity sensor sees less than .2 GPL of salt. Either there's no salt in the pool or sensor is air locked.Generates Code 175- Flow sensor airlock
183-186Flow salinity sensor temperature probe error codes. 1.They all generates code 172- Flow sensor service is required.
2. Perform diagnostic test on board to ensure the board isn't faulty. If not the board, the tri-sensor is the culprit.
3. How To Change a Jandy AquaPure Tri-Sensor
187Front board power supply is either too low or too high.1. Generates code 173- Low input voltage, IF code 188 is present.
2. Generates code 170 IF 188 is not present.
188VAC input voltage too low.Generates code 173 if code 187 is present
189Relay not conducting in the forward direction.Generates code 171- Back board service
190Relay not conducting in the reverse direction.Generates code 171- Back board service
191High cell current (at upper limit of A/D converter) and cell voltage falls below 19V.Generates code 170- Front board service
192High cell current and cell voltage falls below 19V.Generates code 171- Back board service
193Measured significant cell current when SCR's were turned off.Generates code 170- Front board service
194Cell current is 85% lower than desired and cell voltage above 19V.Generates code 125- The cell is dirty or needs replacement
195Salinity invalid due to out of range measurements caused by front board error.Generates code 170- Front board service

  1. 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?

    1. 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.

    1. 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.

  2. 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. 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.

  3. 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?

  4. 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. 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)”

    1. 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.

  5. 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. 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?

  6. 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. 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.

  7. 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?

  8. 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?
