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!
