Level 2 Service Codes
If you encounter a Level 2 Service Code, contact a quali
fi
ed service representative.
Code Number
Possible Cause
Corrective Action
180
Heated sensor element not heating.
(Generates 172 code)
Contact a quali
fi
ed service representative.
181
Flow sensor temperature sensor failure.
(Generates 172 code -
fl
ow sensor service)
Contact a quali
fi
ed service representative.
182
Salinity Sensor sees less than 0.2 gpl of salt, no salt
in pool or sensor air locked.
(Generates 175 code –
fl
ow sensor air lock)
Contact a quali
fi
ed service representative.
183-186
Flow salinity sensor temperature probe error codes.
(They will all generate 172 codes which indicate
fl
ow
sensor service is required)
Contact a quali
fi
ed service representative.
187
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 quali
fi
ed service representative.
188
VAC input voltage is too low.
(Generates 173 code if Level II code 187 is present)
Contact a quali
fi
ed service representative.
189
Relay not conducting in the forward direction.
(Generates 171 code - Backboard service)
Contact a quali
fi
ed service representative.
190
Relay not conducting in the reverse direction.
(Generates 171 code - Backboard service)
Contact a quali
fi
ed service representative.
191
High cell current (at upper limit of A/D converter) and
cell voltage below 19V.
(Generates 170 code front board service)
Contact a quali
fi

192
High cell current and cell voltage below 19V.
(Generates 171 code – Backboard service)
Contact a quali
fi
ed service representative.
193
Measured signi
fi
cant cell current when SCRs were
turned off.
(Generates 170 code – front board service)
Contact a quali
fi
ed service representative.
194
Cell Current is 85% lower than desired and cell
voltage above 19V.
(Generates 125 code - Cell dirty or needs replacement)
Contact a quali
fi
ed service representative.
195
Salinity invalid due to out of range measurements
caused by power board error.
(Generates 170 code – front board service)
Contact a quali
