The FL is related to the pressure/flow switch or sensor so I would start there. Do you know what control system is in the spa? Well, It is a balboa model not in front of me but after all my research and almost buying a new powerpack, my problem was the pressure switch. The professional I had out though b/c of no pump action that could not be the problem. Easy fix and learn alot so thankful!

So I'm very new at this hot tub and forum so excuse me if I'm butting in but I'm having a similar problem as mojord. Although I'm having more of a dead spa. From above posting it sounds as if the pressure switch is closed. Just installed used tub, powered on and got FL on top control with no movement in water. Powerpac clicks when powwered on but thats about it. Left it alone for a day and turned on again last night and everything seemed to work fine. By this morning tub was back to FL reading but water was still warm/steam. Before spontanious working tub, we metered connections and got feedback(volts) from neutral line. Otherwise seemed fine. Tub seems to be in a sleep mode of some sort?? Assuming I will be told to try everything that is previouly posted here but just wanted to make such due to "dead spa". Thanks
