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).
