Spa electrical problem

[abby2013]

Our sundance 850 altimar has been wonderful for 10+ yrs. yesterday our lights flickered in the house like a power surge/outage and this morning the spa was dead- breakers reset ...nothing? What should I check.... Circuit board or power supply? Both are pricy.

Look for burn marks on the circuit board. That's what it probably is. We just had a customer experience the exact same thing.

Do you own a non contact voltage tester? If Yes the first thing I will check if you receive a power to the hot tub. Next check a small fuse in the control box. Might be burned out (check the image I have attached. I marked a fuse using red rectangle)

well good news. I looked at the board/fuses-nothing burned up. Then I cycled the main circuit breaker back on to try my noncontact voltage tester everything started up just fine. Thanks for everyone help!
