tigerriver

Hello, I have had a Tiger River Spa for 3 years, no problems ever. Last night I opened the spa, ran the cleaning cycle 2 times (10 minutes each) When I came back to check, the spa had no power at all. The control panel does not light up. The tub was connected by a professional with the required connector and is on the gfci and has a dedicated connection to the service inside the house. never had an issue. I reset the breaker many times, reset the gfci plug. It has a test and reset button on it and it lights up fine. Just no power to the tub. so, should I call an electrician or are there tub professionals I should call? Any ideas what the problem might be? Thanks, worried tub owner.
