So I'm trying to get a spa going to do a decontamination flush. I filled the spa and when I plug the large spa plug into the outlet, the power indicator on the plug comes on, I hear what I think is the spa low flow pump come on, the spa control panel lights up(power light, ready light ,and display back light), but then a second or two later the spa turns off. No lights on the control panel, maybe I hear a relay(s) click, and the power light on the large plug goes out. If I hit the reset button on the large plug then the same thing happens as before with the power coming on momentarily and then shuts off again.
One guess is the system is tripping the GFCI feature.
I'd appreciate any hypothesis on what's going on and next steps for troubleshooting. Thanks in advance. This forum is great
I'm going to try and add a link to a video of what's happening. Sorry I'm not showing the spa control display. I'm over by the plug pressing it's reset button. I also removed the cover to the wiring panel and you can see some of the lights that come on and go off as well.
Please let me know if you are able to view the video.
here's the video on skydrive
Okay, Here's some more info. If I start the jets during that small window there is power to the spa, the power stays on. When I turn of the jets the power goes out again.
In the owners manual it mentions that for a 115 volt wired spa, which this is, it will not run the jets and the heater at the same time. So as long as the jets are running the heater will not turn on. That tells me when I turn the jets off the heater is coming on and then perhaps something heater related is kicking off power to the spa including the power light on the large GFCI plug.
So what might be my next steps for troubleshooting the heater?
