The spa is new delivered Wednesday. All wired Thursday evening but not switched on because it was late and I hadn't filled it yet. Last night I filled it and switched on breaker and nothing. Electrician will return today to make sure nothing else was missed or improperly wired. I'm a licensed automotive technician of 15yrs and have gone over everything myself also and only thing I can see that was missed was the switching settings. I'm usually pretty self sufficient with these thing however 12k for a tub is a lot of cash to not be 100% so I hired an electrician... I also don't believe any damage has been done but if it has, just a circuit board woukd likely need replaced? I was supposed to be soaking my bones in it as I'm typing this. Thanks so much for your time! Spa is a j275 from jacuzzi
