Popping noise in Caldera Spa
bobh:
I own a Caldera Niagara (2003 model) spa. I get occassional popping noises which I cannot identify. They mostly come from the front of the tub but sometimes sound as if they come from other places. If I use the tub for a half hour, I may hear the noise once or twice. Its sometimes quite loud (enough to startle you) and sounds as if something hard hit the shell. Also, its seems to happen more frequently as the weather gets cooler. I've never heard it while working outdoors and the cover on, only when the cover is removed. I've even disconnected power thinking it had something to do with the heater pump or ozinator but the noise is still there. It happens without the jets on. Neither the local dealer nor Caldera know what the problem is. Any ideas?
huh?:
Welcome to the board BOB! That noise you hear is stress leaving your body. Just kidding. Are you sure it is coming from the spa? My first thought might be settling of the deck.

Do you use a cover lift? If so it may be the cover smacking against the side of your tub in the wind... :-/

The tub sits on a solid, thick (6") concrete pad. So no deck noises. The top has a lifter, but the noise happens whether its windy or not. However, since I have never heard the noise with the top closed it could mean cabinet stress from supporting the weight of the top. I think that I'll try removing the top completely to see if the noise goes away. Thanks for the idea.
PPOL:
Is the noise coming from the equipment compartment? Sounds like you might have:
A) a bad pump, does it happen when Jet 1 is running or Jet 2 running?
B) Clogged Circulation pump? Do you trip the breaker when you remove the filter from the filter compartment? It is recommened you do so, so that material doesn't fall off the filter and into the circulation pump.
C) Make sure your ozontor isnt clogged.
Good Luck,
