FLO Error.. New Flow Switch, New Circulation Pump..What now?

[nicbordelon]

I came home the other day and found the tub with no power. I checked breakers and fuses. An internal fuse was blown. I replaced it. Power restored. FLO error message appeared, and the circulation pump would not come on. I replaced it. Then FLO error... I replaced the flow switch. Now it activates for a few minutes, then FLO appears. I unplug from the board, replug and it works a few, then FLO message. Don't know whats next!

Thanks for your help!

This spa has a flow switch that should be closing when the circulation pump is running. It is in a transparent tee and you should be able to see the water flowing through this switch and closing the paddle to avoid the flo error code. Can you see if that switch is closing while circ pump is running.
