We just got a Sundance Tango hot tub from my brother, hooked it up, and have been getting a FL 1 error.
When we hit the breaker, the tub turns on and immediately gives the FL 1 error, then after about a minute it goes away and begins to heat up. The main pump seems work fine. After about 20-30 minutes, the FL 1 error comes back and will stay there until I turn off the tub and reset it.
We get the error regardless of whether the filters are in or not (they are brand new anyway), I've checked for clogs everywhere and there is nothing. I checked the ohms on the flow switch and they are within range from what I have researched. I think it might be the circ pump, but want to be positive before I go out and get another.
Thanks for any thoughts
