I have a LB spa Gseries 6person 10 year old.. we recently bought it used...everytime i turn on the waterfall feature *a small twist type valve on top, i think* i get the Flo/Temp error i can turn the valve off and error goes away any suggestions? besides not using waterfall LOL
thanks bunches

The 24 hr circulating pump may be clogged. When you open up the back waterfall, the pressure
drops, and the pressure switch drops out. Remove the front panel, and see if your small pump
(to the right of the control box ) is a black Grundfos. If so ( and on Baqua spa ) the closed face
impeller is collecting lint. If it is grey, it may me clogged with pinestraw etc. If it is a Tiny Might
(Usually Red), it is probably failing.
