A Guide To iAquaLink Error Codes
Advice - Pools
LEVEL 1
| 120 | Low cell current in forward direction - check DC cord, clean cell if necessary or replace cell |
| 121 | Low cell current in reverse direction, same as 120 above |
| 123 | Low to no current at cell - check DC cord, clean cell or replace if necessary |
| 124 | High current indicated at the cell - this usually means a bad PIB |
| 125 | Cell needs to be cleaned or replaced |
| 126 | Low current in forward direction and VAC input voltage below 100/200 VAC - check input voltage, transformer and PIB voltages |
| 127 | Low current in reverse direction and VAC input voltage below 100/200 VAC - check input voltage, transformer and PIB voltages |
| 144 | Low Salinity (below 2.0 gpl) - indicates the pool needs salt added |
| 145 | High Salinity (above 4.0 gpl) - indicates pool needs to be diluted |
| 170 | PIB service condition indicated and is usually caused by low incoming AC voltage - check transformer voltages or for faulty sensors |
| 171 | PIB service condition - indicates board needs to be replaced |
| 172 | Flow sensor service - clean sensor, check for damage and replace if necessary |
| 173 | Low VAC input voltage and on-board power supply is not regulated - make sure unit is wired with the proper voltage |
| 174 | Pool temperature is too high for operation of AquaPure® (i.e. > 108°F) |
| 175 | Flow sensor air lock condition or very low salinity |
LEVEL 2
| 180 | Heated sensor element not heating (generates 172 code) |
| 181 | Flow sensor temperature sensor failure (generates 172 code – Flow sensor service) |
| 182 | Salinity Sensor sees less than 0.2 gpl of salt, either no salt in pool or sensor air locked (generates 175 code – Flow sensor air lock) |
| 183/186 | Flow salinity sensor temperature probe error codes. They generate 172 codes which indicate flow sensor service is required |
| 187 | PIB power supply either too low or too high (Low input voltage code 173 if Level II code 188 is present) (code 170 if 188 is not present). |
| 188 | VAC input voltage is too low (generates 173 code if Level II code 187 is present) |
| 189 | Relay not conducting in the forward direction (generates 171 code - PIB service) |
| 190 | Relay not conducting in the reverse direction (generates 171 code - PIB service) |
| 191 | High cell current (at upper limit of A/D converter) and cell voltage below 19V (generates 170 code PIB service) |
| 192 | High cell current and cell voltage below 19V (generates 171 code – PIB service). |
| 193 | Measured significant cell current when SCRs were turned off (generates 170 code – PIB service). |
| 194 | Cell Current is 85% lower than desired and cell voltage above 19V (generates 125 code - Cell dirty or needs replacement). |
| 195 | Salinity invalid due to out of range measurements caused by PIB error (generates 170 code – PIB service). |
