Welcome to our forum.
I have a hot tub with Gecko controls, SSpa pack. I recently drained the water for maintenance, and after a few weeks, refilled. After refilling, I turned on the tub and it tripped the breaker. I replaced the heater element, and pressure switch. That stopped the breaker from tripping. Now I'm getting a FLO code. The code was happening at both high and low pump speed, but now only on low. I removed the filters, intake screens, and put a nose down the filter well. The jets seem to have good pressure, and all are open. Any ideas as to the problem?
The sensor located in the heater tube.
The overheat is not in the tube, it sticks to the outside. The flow(pressure)switch, is new. It is adjustable, but I did not turn it. Since my last post the tub is no longer heating. I think I burned out the new element. Could the pump be weak, and not supplying enough water on low speed? Won't the high limit code showed up?
Thanks for the help Tman, and Jim. I don't know the manufacturer, the cabinet was replaced, and I cant find a tag. I will post a picture, maybe someone will recognize it. The year is approximately 2000.Before draining I had no FLO code, and it heated fine, however, I was getting a High limit code. I replaced the heater, due to the breaker tripping after refilling. When the heater was disconnected, the breaker didn't trip. I replaced the high limit switch as a preventative maintenance issue while I had the heater tube out, but the switch may have been the problem all along. The FLO code did not go away when the pressure switch was bypassed. I adjusted the pressure switch, It is now heating, and running with NO codes at all!! I hope the problem is solved. I have a few questions about jets, and I hope you will be able to help me out. I'll save that for another day.
Lets circle back to the age, make and model of the tub?
