I have a Hot Springs Grandee that was installed in 1988. It has not had any water in it for 3 years. I filled it with water but it's not heating up. None of the breakers are tripping. I took apart the SilentFlo 5000 circulating pump (not magnetic) and put a new hose on and confirmed that it is circulating well. But I still have no heat. The heater box is cold to the touch.

What's my next step in solving this problem?

thanks

Is the heater breaker (the 30 amp 220v breaker) good? (Be sure to get 220v across the poles)

Are the elements getting 220v?

Hi everyone,

I have a similar situation, with a little more background. I have a used Grandee (about 1999) that when I bought it the owner told me that I needed to reset the heater sometimes when the power was cut from the hot tub. Last weekend we had a power outage, and as usual, I needed to reset the heater by pressing the button on the element itself. When I reset the heater, it comes on and warms up, but only for about 2-3 minutes. I tried shutting the spa off at the breakers (which are not flipped) and then turning it back on and resetting the heater, but it keeps kicking off after a couple of minutes. My questions: 1.) do you think the heater is simply "shot" and needs replacing? 2.) could it be in the thermostat/electrical box problem? If so, how would I find that out? Or 3.) something I am not thinking about?
Thanks,
Nick

I have finally got the control box open and the first thing I figured out was that one of the legs on the 2-pole breakers was not seeing 120V. This is a Square-D 30A GFI breaker. I think it's this one: http://www.bestcircuitbreakers.com/Circ... iAodkz8ggg It looks the same. Can someone here confirm that it is the proper model. thanks Nick

That's the right one.

to jnporcello,

do you have circ. pump flow? Dirty/ clogged filter on the grey/hollow standpipe? Try removing the filter.

Thanks,
That was it. The filters needed cleaning. I'm glad it was that simple.
