Hot Tub Error Codes

Balboa ML900 control

The Balboa ML series contains some of the most advanced topside controls with a complete set of error messages and self-diagnostics. Other systems provide less comprehensive error messages, but still enough feedback to identify a particular issue.

Error messages may be similar across systems. Old style pressure switch systems would show a FLO or FLOW or FL error to indicate that the pressure switch needed calibration or that there was an obstruction or dirty filter in the line.

Error messages can help troubleshoot hot tub problems and get the spa running again.

  • pressure switch problems
