No power to hot tub
Electrical keeps tripping. we changed the braker box, changed fuses in the hot tub.....nothing...when we turn the switch back on in the braker box, we hear the hot tub click, but the power never turns on.
We have a QCA model # keywest purchased new in 2006. It started "tripping after 3/4 of a cycle....we have always kept the tub clean, but the water began to get a green hue to it, so we totally emptied it, started over, and it worked great for 2 weeks again, now it tripped and we can't get it back on. The tub is on its own breaker box.

In all liklihood, your problem is a breakdown in the insulation of the heating element. The elements tend to be mineral insulated then metal jacketed. Once you get a bit of corrosion on the jacket and a little water gets into the mineral powder, it's insulation properties fall off sharply, shorting out the power supply.
There are two practical ways of testing this:
The pro way of doing it is to borrow a high voltage insulation tester, disconnect the power leads from the element and check the resistance between one of the elements terminals and the jacket. Treat anything less than a megohm as a failure requiring replacement of the element. (nb. This is one of those rare cases where you need to use a proper insulation tester - an ordinary multimeter often fails to find this problem)
The alternative is just to replace the element and see how much difference it makes.

If you don't have an ozonator on this spa, then it could be the heater. If you do have an ozonator, unplug it and see if the problem goes away. Moisture in the ozonator can cause short circuiting. Otherwise, heater element could indeed be culprit, or if the element touches the sidewall of the heater tube, that can also be a short.
