Spa (1999) IQ2000 motheboard.

Spa was running when the basement flooded and we got 7 1/2" of water. I've been drying out things and the circulation motor runs fine, the jet pump motor worked when directly connected to an outlet.

If I remove the two plugs from the side of the motherboard housing that go to the heater the spa will run the circulation pump and the red light blinks. If I connect the two plugs from the heater, a relay clicks after a few seconds and it blows the circuit breaker. So, water has to have gotten inside the heater (no-fault 6000) running on 110v.
Has anyone taken one of these apart? The reset is not popped on the heater. Any major electronics inside the heater that could go bad or is it just wet and still shorting out?
The main motherboard is not burned nor appears to have been overheated at all.

It sounds to me as though the heater's wet and still shorting out. Not a servicable part, only replaceable. Try letting it dry out a while longer- also, check the back of the small 24 hr. circ pump for water intrusion.

You most likely got water into the wires in the black 'accordian' looking tubing that runs between the back of the heater and the thermal cutoff switch. You can take the screws out of the square box on top and see if there is water in there and dry out the wires.

I'm not too familiar with the inner workings of these heaters. From a dealers point of view for safety reasons when they have prblems I just put new ones in.

You beat me to the punch...I was getting dinner inbetween reading and responding. We pretty much have the same response on all of the HotSpring problems...I guess that's a good thing!

Thanks to both for the ideas. As I'll probably have to replace the heater I might as well see what shows up when I remove some screws and have a look see. Expensive part to replace!!

The small circulation motor (silentflo 5000) seems to work fine now that it's dried out.

Gotta drain that tub!

You don't need to drain it if you don't want to. You can unplug the heater wires from the board and let the circulation pump run. Even with the temps around 32 degrees you'll be fine with the water moving.

When you go to replace the heater you can crimp off the 3/4" lines with 3 pairs of needle-nose vise grips.
