Thanks for the info. I appreciate it.
Since my post, the Spa guy came back out and I told him what people have been saying the problem may be (like you stated below).
I got the response I thought I would again which was "I've been working on Spas for 15 years, I looked for leaks, and checked the heater & motors and all is ok with the Spa. It's an electrical problem and not related to the Spa".
Now it's time to spend more $ on a new Electrician's opinion. I love my spa but I think if I get the same answer 1 more time, it may be time to sell the Spa since no one can seem to fix the problem, just blame each other (with me paying for opinions & getting nothing in return

)
