There had to be some kind of mis-comunication about the conductors (wires) feeding your spa circut.
Imagine trying to just bend #6 non-stranded!
You might want to start over by calling out some other "service guy." for a 'under warrenty service call.'
This time just tell them the required information. Like address, make, model, warrenty questions and stuff.
Just give the symptoms (dont cut your own throat) of the problem. If they even want them.
Something like:
"I have a tsunami spa. I have had it only 2 months. The other day it quit. The next day it sounded like it wanted to start up for a few seconds and then it quit".
The last thing you want to say is "I opened the cover and" make a big red flag pop up in the guys mind.
