Jacuzzi Caressa model 8780000
I inherited the above-mentioned hot tub in the house we purchased. After replacing a cracked jet and a few tees and lines, I started this beast up. I set the temp (old dials) and the water heated up fine over night. The system filter/heat selection works fine. Replaced the filter. Tub starts up if the temp gets too low etc. But, when I turn the jets on the system shuts down after Appx 2 minutes. I reset the 30 amp button on the electrical box to get the system back and running. I try to reset the high limit switch, but it appears to be stuck. I can't push it in or pull it out. I took the housing off and pulled the bulb out (how far does it go in the tube?)
I assume I should replace it, but it seems strange it will work fine without the jets. Do thejets increase the temp?
Thanks,
Rick
