We have a Hotsprings/Watkins brand hottub/spa that came with the house we bought last September. At the time that we bought it, the hot tub appeared to work and heat up properly. However, now that we've unwinterized it and tried to use it, it no longer heats up and the water temperature stays at 70 F. The power to the hottub works ok and the jets, light and control panel all seem to work ok.
At first we found that the circulation pump wasn't working and we though that this is why the water wasn't heating up. We bought a new pump and now the bubbles come out of the bottom circulation vent at the bottom of the tub, but the water still doesn't heat up. Does this sound like a problem with the heating element? We're not really familiar with hot tubs and aren't sure how to troubleshoot this other than look at the obvious. People online talk about breakers in the inside control panel, but I couldn't find any and the only fuse in there is in tact. The only breaker I know of is the external breaker in a breaker box outside the hot tub. Any ideas are appreciated.
