gillnick Posted December 18, 2023 Report Share Posted December 18, 2023 Hello have a jacuzzi 355 with intermittent Flo error. I have replaced the flow sensor and cir pump. Also checked for air locks and have removed filters. The spa will continue to heat and circulate until it reaches set point temperature and then goes into Flo.

Spa Board Doctor Posted December 19, 2023 Report Share Posted December 19, 2023 Hello, Is the "FLO" error solid on the display or does it flash between "FLO" and the current temperature? Brandon Quote Link to comment Share on other sites More sharing options...
