Rg123 Posted August 28, 2023 Report Share Posted August 28, 2023 Hi All, I was hoping someone could help me with some troubleshooting. I have a 2015 Hydropool Serenity 4000. The pump will work on the HIGH setting once(15 min cycle) but will produce a FLO error if you try to run it again. The FLO error will clear on its own after 30 mins or so. Things I've checked: -ensured water level is high enough -tried running without filter(same error) -made sure there was no air in the system(loosened union nut and only water came out) What should my next steps be? Any ideas on what could be the issue? Thanks Quote Link to comment Share on other sites More sharing options...
