Jandy AquaPure Error Codes Troubleshooting

Nothing is more frustrating than getting an error code that your nothing about. Not knowing the the cause of the problem makes fixing it much harder. That’s why we’ve put together our error codes list below. Take a look and make life a bit simpler.

aquapure error codes

If you have a Jandy AquaPure 700 or 1400 chlorinator, there’s a chance you may have come across a service code (or error code) before.  A service code is a three digit number that appears on the display panel of an AquaPure Control Box, letting you know if your AquaPure unit is experiencing any problems.

Service codes are fast, easy to read, and not only identify the problem, but direct you to an available solution.  Below you’ll find a complete list of AquaPure service codes, what they mean and how to correct them—all in one convenient table.

Service Codes:
Code #Possible CauseCorrective Action
120Low current in forward direction to cellClean cell if necessary and check DC cord
121Low current in reverse direction to cellClean cell if necessary and check DC cord
123Extremely low current to cellClean cell if necessary and check DC cord
124Higher than normal current to cellContact a pool professional
125Cell needs to be cleanedClean cell if necessary
126Low current in forward direction and VAC input voltage below 100-200 VACContact a pool professional
127Low current in reverse direction and VAC input voltage below 100-200 VACContact a pool professional
144Low Salinity (below 2.0 gpl)Add salt to pool to achieve 3.0 gpl
145High Salinity (above 4.0 gpl)Backwash filter if a DE filter is installed. Partially drain pool and dilute with fresh water until salinity returns to 3.0 to 3.5 gpl
170Possible front board service condition or unit not correctly wired to 120 VACContact a pool professional
171Possible backboard service conditionContact a pool professional
172Flow sensor service condition or flow sensor is unpluggedContact a pool professional
173Low VAC input voltage and on board power supply is not regulated or unit not correctly wiredUnit wired to improper AC voltage. Contact a pool professional
174Pool temperature is too high for operation of AquaPureFlow/Salinity sensor indicated water temperature at sensor above 108 degrees F. Reduce water temperature
175Flow sensor air lock condition or very low salinityVerify proper flow/temperature/salinity sensor installation. Check salinity with Myron “L” meter calibrated for NaCl or test strips. Add salt as necessary

Jandy recommends that you contact a pool professional for service if you encounter a Level 2 code.

Level 2 Service Codes:
Code #Possible CauseCorrective Action
180Heated sensor element not heating. (Generates 172 code)Contact a pool professional.
181Flow sensor temperature sensor failure. (Generates 172 code – flow sensor service)Contact a pool professional.
182Salinity Sensor sees less than 0.2 gpl of salt, no salt in pool or sensor air locked. (Generates 175 code – flow sensor air lock)Contact a pool professional.
183, 184, 185, 186Flow salinity sensor temperature probe error codes. (They will all generate 172 codes which indicate flow sensor service is required)Contact a pool professional.
187Front board power supply either too low or too high. (Generates 173 – Low input voltage code if Level 2 code 188 is present) (Generates 170 code if 188 is not present)Contact a pool professional.
188VAC input voltage is too low. (Generates 173 code if Level II code 187 is present)Contact a pool professional.
189Relay not conducting in the forward direction. (Generates 171 code – Backboard service)Contact a pool professional.
190Relay not conducting in the reverse direction. (Generates 171code – Backboard service)Contact a pool professional.
191High cell current (at upper limit of A/D converter) and cell voltage below 19V. (Generates 170 code front board service)Contact a pool professional.
192High cell current and cell voltage below 19V. (generates 171 code – Backboard service)Contact a pool professional.
193Measured significant cell current when SCRs were turned off. (Generates 170 code – front board service)Contact a pool professional.
194Cell Current is 85% lower than desired and cell voltage above 19V (Generates 125 code – Cell dirty or needs replacement)Contact a pool professional.
194Salinity invalid due to out of range measurements caused by front board error (Generates 170 code – front board service)Contact a pool professional.
Additional Letter Service Codes:

LoLow Temperature CutoffTemperature of Pool is < 50ºF (10°C). Chlorine production stopped.
boBoostIn “Boost” mode unit will operate at 100% production for 24 run time hours.
HHHigh-HighInput has exceeded Maximum Range.
JAAquaLink® RS OnlineAquaLink RS is controlling the AquaPure and desired output percentages.
JbBoost (AquaLink RS Interface)AquaLink RS is controlling the AquaPure and “Boost” is active.

Conclusion:  While most service codes can be solved by the pool owner, not all are immediately fixable, and if this happens it’s important to contact a local service technician who can identify and correct the error to ensure safety and warranty compliance.
