Jandy AquaPure Salt Water Pool Systems deliver high performance and reliable sanitation for swimming pools across the globe. To keep these units running at top efficiency, the digital controls will display a code when something needs service.
AquaPure service codes identify the problem and direct you to an available solution. Below you’ll find a complete list of Jandy AquaPure service codes, what they mean and how to correct them—all in one easy-to-read table.
Service Codes:
|
| Code # |
Possible Cause |
Corrective Action |
| 120 |
Low current in forward direction to cell |
Clean cell if necessary and check DC cord |
| 121 |
Low current in reverse direction to cell |
Clean cell if necessary and check DC cord |
| 123 |
Extremely low current to cell |
Clean cell if necessary and check DC cord |
| 124 |
Higher than normal current to cell |
Contact a pool professional |
| 125 |
Cell needs to be cleaned |
Clean cell if necessary |
| 126 |
Low current in forward direction and VAC input voltage below 100-200 VAC |
Contact a pool professional |
| 127 |
Low current in reverse direction and VAC input voltage below 100-200 VAC |
Contact a pool professional |
| 144 |
Low Salinity (below 2.0 gpl) |
Add salt to pool to achieve 3.0 gpl |
| 145 |
High 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 |
| 170 |
Possible front board service condition or unit not correctly wired to 120 VAC |
Contact a pool professional |
| 171 |
Possible backboard service condition |
Contact a pool professional |
| 172 |
Flow sensor service condition or flow sensor is unplugged |
Contact a pool professional |
| 173 |
Low VAC input voltage and on board power supply is not regulated or unit not correctly wired |
Unit wired to improper AC voltage. Contact a pool professional |
| 174 |
Pool temperature is too high for operation of AquaPure |
Flow/Salinity sensor indicated water temperature at sensor above 108 degrees F. Reduce water temperature |
| 175 |
Flow sensor air lock condition or very low salinity |
Verify proper flow/temperature/salinity sensor installation. Check salinity with Myron “L” meter calibrated for NaCl or test strips. Add salt as necessary |
Level 2 Service Codes:
|
| Code # |
Possible Cause |
Corrective Action |
| 180 |
Heated sensor element not heating. (Generates 172 code) |
Contact a pool professional. |
| 181 |
Flow sensor temperature sensor failure. (Generates 172 code - flow sensor service) |
Contact a pool professional. |
| 182 |
Salinity 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, 186 |
Flow salinity sensor temperature probe error codes. (They will all generate 172 codes which indicate flow sensor service is required) |
Contact a pool professional. |
| 187 |
Front 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. |
| 188 |
VAC input voltage is too low. (Generates 173 code if Level II code 187 is present) |
Contact a pool professional. |
| 189 |
Relay not conducting in the forward direction. (Generates 171 code - Backboard service) |
Contact a pool professional. |
| 190 |
Relay not conducting in the reverse direction. (Generates 171code - Backboard service) |
Contact a pool professional. |
| 191 |
High cell current (at upper limit of A/D converter) and cell voltage below 19V. (Generates 170 code front board service) |
Contact a pool professional. |
| 192 |
High cell current and cell voltage below 19V. (generates 171 code – Backboard service) |
Contact a pool professional. |
| 193 |
Measured significant cell current when SCRs were turned off. (Generates 170 code – front board service) |
Contact a pool professional. |
| 194 |
Cell Current is 85% lower than desired and cell voltage above 19V (Generates 125 code - Cell dirty or needs replacement) |
Contact a pool professional. |
| 194 |
Salinity invalid due to out of range measurements caused by front board error (Generates 170 code – front board service) |
Contact a pool professional. |
