Resurrecting a hot tub (Sundance Cameo) that came with the house that we haven't used in a year. I refilled it a few weeks ago and powered it up to run overnight and heat up. The heater was working when When I came out the next morning, the check valve in the ozonator line had broken and about 1/3 of the water drained out of the tub. The break in the hline was above the motor that is connected to the heater and I wouldn't be surprised if that motor got a good shower. We had bad weather for a few weeks and I started back working on it today. I refilled it and once I powered it up, I get a FLO message and a COLD message. I removed the filter and the FLO message remained. I wasn't getting an icon on the panel that shows that the heater was on.
The motor connected to the heater was extremely hot but not turning and I'm thinking that probably what happened is the motor got wet and rusted in the 2 weeks or so that it has been sitting.
I presume that the FLO message and the heater not coming on has to do with that motor not turning.
Does this sound correct?
If so, I would take the motor out and schlep it to my local motor shop to see if they could unfreeze or rebuild it.
