Why would I have the FLO message for several days and after playing with the jet on/off a few times it went away? I mentioned this problem in another message under plumbing for another issue. Havn't seen a circ cycle come up yet to see if it works at that time. My history with this tub is bad, this is the 2nd or 3rd flo switch I have been thru since summer 99. Temp sensor was also replaced with last flo unit may of 2005.

Flo message is back. Pumps work fine when activitied but flo still there.

See my post different message under "slenglish"...I have not solved problem yet...It may still be in the Laing circulation pump even though it is new...I am not getting sufficient flo thru heater and that is when error code comes on when I run I believe the 2 stage pump heater is ok...it shuts off and circulating pump takes over runs for 3 minutes and flow diminishes...heater shuts off and flo code comes on....if you fix your problem let me know...I will have tech here today...
