Vita has had some funky controls over the years, but nobody has plug-in relays that I know of. But those funky controls have issues unlike the usual guys. Still likely a stuck relay, but not as certain as with a balboa or gecko or even watkins. Haven't seen one in a good decade, so no clue...

Both wires are "hot" as far as a gfci is concerned. The heater cannot run without the circ pump. Not saying it's not a pump, just that it's harder to pinpoint than that. Also, breakers go bad too, often along with another failure (heater, pump) which could be the case here. The fact that you...

The haze is likely scale (calcium). While you can discolor acrylic, it's not easy. Try a magic eraser on it. Have to say, a 4 year old caldera with acrylic bubbles is absurd. You can't cause delamination like that, it's a manufacturing defect that watkins figured out how to avoid decades ago...

You've heard alot of bs. What brand of spa? What year? Post pics of the equipment area, wiring diagram, and circuit board.

Ozone generators are rated in hours, and yours has a rating somewhere in the specs if not on the unit.

Every frame has it's issues. I remember when masters dropped the stainless steel frame on the market, everyone (including me) was awestruck. What a great idea! Now, twenty-some years later, you can't give them away because the rusted, corroded frames are unfixable.

So, did it work?

Likely the air intake for the jets or a blower line with no blower. Lift it above water level. If it stops leaking keep it there. If not, you are pressurizing your vacuum lines and probably have some bad jets.

Yes, you must replace it. No, those valves are not for it. Drain it or get wet. The hose on those is usually attached with a hose clamp, so it can be removed without cutting, but not always. If you can't get to it then you will have to lift it and cut a hole in the bottom pan.

That's a control side issue. The board is turning off power to the pump. If there are no errors displayed on the topside you have a bad board.

It could be a suction-side slice valve. They are known for sticking on older tubs. Sometimes the handle pulls out of the top. You can also test at the pump plug on the board.

But this isn't foaming, it's fizzing. There is no foam, but the water does cloud with the injected air and it fizzes at the surface. As I said previously, if you've never seen it you'll have no idea what we're talking about, but it happens. And it resembles the tiny little droplet that goes...

That's a fascinating video, and on-topic as it shows in extreme slow motion an effect that highly resembles the one under discussion. I had hoped that some of you might watch and have an opinion on it, but it somehow turned the thread into an aqua-clarity ad followed by a humorous discussion on...

Sundance does not use a filter housing, they use a filter well moulded into the shell. There is no housing that will fit a SD filter that I am aware of. I'm confused as to why you would want one. Available housings have filters designed for them. If you are installing a housing just use the...

Not if it's from the dealer. DIY is another story. Old spas that were not plumbed properly to contain the ozone until depleted and injected it directly into the footwell would do all kinds of damage. Nobody that I know of has done it that way for a good decade or better. Certainly not a quality...
