Thanks! No, there are no error codes. It's as if it thinks it's working fine. I did do the breaker reset - no luck. If it's a relay board... is there any hope that I can acquire this part and replace it myself, or is it soldered or otherwise complicated? If it's "plug and play", I can handle it. Thanks again! Is the "temp" icon flashing on the control panel? If it's not that or any other error codes on the control pad then you would need to do some tests with a meter in the control box. Try taking the filter out and resetting the breakers. Most likely problem is a bad heater relay board.

I have a 2002 Kuaui. It has stopped heating properly. The temp is set to 101, but is at 94 right now (though it's only about 50 degrees outside). I hear a nonstop humming - possibly the heater trying to work? I can't afford to pay someone to come and diagnose. Is there anything that I can do to check out obvious issues before I have to pay a tech? i.e. is there a switch that can be tripped, something that can be clogged, etc?? All help appreciated. Thanks

Is there any flow coming out from the circulation pump? It comes out of a small "jet" down near the footwell. It may have air in the line and if so you would need to bleed it out. Thanks! I just went back out to check what you wrote. I had turned the circuit breakers off after the total frustration of an afternoon of trying to set it up... So, I turned them back on when I went out. I opened the cover and saw some air bubbles come out of that small jet in the footwell. I hadn't done anything but plug it in. I then turned on the jets and it ran... and a "soft" flow came out of that hole. NO four blinking dashes anymore and it didn't turn itself off. Yeh! But, the temp light is still flashing??

I have just gotten a used tub = Caldera Kuaui. It showed a flashing "temp" light and then went to The "heater high limit thermostat tripped" symbol within the first hour of running it in new location. Help??
