Hello...I started up my hot tub this spring and when all the jets were running the power stopped. The breaker had tripped so I reset the breaker but there was no power showing at the hot tub panel. I had an electrician come out and he said power looked fine from the panel to the spa pack. I contacted my hot tub technician and he identified that the main board was faulty. He replaced it and for 2 weeks all was fine. The the same thing happened again! Has anyone had this experience before? Any suggestions what could be causing this before I replace everything in my hot tub? My technician is coming out again but I thought I would run this problem through this forum for ideas. Thanks
