Anyone have, or know here to get, a wiring schematic for Hercules Tornado spa pack?

I would check the pump and motor. When pumps sit dry for extended periods of time, the pump shaft seals will bond to the shaft. If you know how to work with pumps and electric, you can pull the motor/pump assm. and see if you can turn it by hand, if you can get to it in place try it, be sure breaker is off in the event it breaks free you my loose a finger or two. Electric motors can bind from sitting also, or field windings can corrod causing the motor to lock up and trip. Often all it takes is to free up the pump/motor and it will take off, be sure to check seals and lube if needed and watch for leaks. My tub sat for 8 years, took pump apart and freed it up, runs great.

I believe the same as John, the whining you are hearing is the motor trying to start, but with either a bad capcitor or damaged winding, it cannot. There may be a burned/bad spot in the winding and by turning it, you are allowing it to create the field to start. I had a motor that I could turn by hand, with power off, when I powered it up, the load spiked to 100 amps and I couldnt turn it with a breaker bar, it had a failed winding, and it would hum like crazy. The safeguard, is the breaker, some motors have a breaker built in, but not many. Send it back, or have a local motor shop test it for a few bucks, before investing in shipping costs?

PSI switch adjusted too high, problem solved, thanks!

If they are not replacing the tub, ask to get the electrical GFCI panel and all the wiring you can get, sub panels can be bought at Home Depot (US) for $70, the wire will kill you, 6ga THHN is $1 per foot x 4 conductors, so $4/ft from the panel to the tub, and the 6ga Romex from the homes breaker box to the outside wall $2.75/ft. My install was relatively close to the breaker box, still cost $300 just for wire, then add in conduit, dont forget those costs.

Anyone have any idea where to find the batt insulation that comes wrapped in the vapor barrier, my tub had Owens Corning Miraflex in it and has become water logged and needs to be replaced. Anything equal to, or a type that would be appropriate to substitue? The original product has been discontinued.

New to spas, I have an Aquatic Industries tub with the Hercules control, when running it on the timer, the pump will shut down but the heater continues to run, is this normal to have the heater run with out the pump circulating water? I have run the spa up to temp and the heater does shut off, just concerend about leaving it run with no circulation? I have verified the pump is shutting off, not on low speed.
