Flo Error after turning Sundance Cameo

[reidthaler]

I turned off our hot tub when we were gone for a week. Turned it back on, and also turned on the jets. A few hours later, I heard the jets were still on and turned them off. Checked the tub this morning and have a FLO error, which surprised me since the tub was already filled with water. I removed the filter, even ran a garden hose into the filter inlet, but still get the FLO error even when I turn the tub off for a while.

Thinking it's time to drain the tub anyhow, but don't want to fill the tub and still have the error.

Ideas?

Thanks,

Reid

@RDspaguy may have some ideas when he wanders by.

Is it flashing (alternating with temp) or solid flo?
Do you have a multimeter and know how to use it?
Does your tub have a 24hr circ pump for heating?
Post pics of circuit board, wiring diagram, and equipment area.
I suspect your circ pump bit the dust mid heat cycle triggering an OH (overheat, ya perv) which turns on the jets until it cools, but thats only about 75% certain at this point. Need to poke around a bit to be sure.
