help Chas, Envoy broke.. control not lit

[flajoker]

hot tub has no power. 04 envoy, Just returned home to take a soak after being out of town. Tub is dark, power to breakerbox.
Turned off breakers and reset, no lights, no nothing on control panel.
Would there happen to be a reset switch or anything like that on the tub?
Would like to have her up and running

[Chas]

Reset is electronic.

Open the sub panel and press any one of the 'test' buttons.  If the breaker pops into the tripped position, call your spa guy.

If they don't pop, then your 50 amp breaker is tripped back at the main panel.

Let me know...

If I press the test button, they trip as they are suppose to do.
I've turned them off and back on...still nothing to the tub.
They don't trip when you turn them back on unless you hit the test button.

Then you have a loose wire or other problem. If you are a do-it-yourselfer, the spa end is the easiest to check: open the cover on the (black) IQ2020 box and simply look at the wires.  There are five wires in the junction block, and a ground. See if they are all in place.

Next open the face of the sub panel and see if all the wires are in place there.

If all are in place and none look burned or broken, call your spa guy.

One last thing: occasionaly the fifty-amp breaker will trip on only one half or one side. It is a two-pole device: if your breaker only has one single handle, then disregard.

But if it is two breakers bridged together, or a single unit but with two handles bridged together, then be sure you turn it off really firmly and turn it on again. If one side pops only, the gfi in the subpanel may still trip as your have but the spa is only getting 110 and if it's not on the correct side, nothing will work. If it's on the wrong side it might light up the power indicator but not run anything.

Chas,
That last post reminded me of a Jim Arjuna rant.  I had to skip most of it because it went way over my head.

Yes, I don't know if Mr. Joker wired his own spa or just wanted to know where the reset button might be - so I sorta covered my bases - to the extreme.

But at least I didn't put in any mathmatical formuli !

Actually it's formulae

Good chance that you have a blown fuse that supplies the transformer.  Many boards have soldered on fuses that make replacement a pain in the butt.  Call your local service tech!
