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

 

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.

  1. I’m getting a code Lo. I know what it means but is there a way I can fix it myself. Please advise. Thanks in advance

  2. 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. 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.

    1. 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.

  3. 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?

  4. I keep getting code 175 and 182 (air lock) codes on my Jandy aqua pure salt generator. Please advise.
