I have a 2 month old Caldera Moorea tub. 3 different times jet pump 2 has shut down after 1-2 hrs of running. When this happens it will not come back on and just hums. I believe it's the thermal cut off as after it cools down after a hour or so it will work ok. It's happened these times when the kids will be in for a little while, then the adults go in (thus the extened run time). The dealer came right out after the second time and ran it full blast for a hour and it was ok. All the diagnostics were ok and he said during his run time jet 1 was actually running hotter than 2. There were no voltage drops, every thing was fine. He told me not to worry if it keeps doing it or if it finally gos it'll be covered. Any body have any ideas?? I did email Caldera but they never replied,maybe they knew the dealer came out? It happened tonight and cut my soak time (finally in the low 30's
), kids were in it before me as my daughter had some friends over. Just hate to have it go in the middle of winter.
