Hi Dave, I feel pretty dumb right now. The spa was part of my house when I moved in and with the position of it, I have only just realised that there is another pump along with the circulation pump. That is exactly where the humming is coming from. I have to empty the spa,move away from a wall so I can get to it. Thanks so much for the advice, without it I wouldn't of even realised there was a second pump. Hopefully not going to be a big $$ fix. Cheers mate.

Hi Dave,thanks for the reply. I have recently replaced the circ pump. Is that what you mean when you said the motor is seized? The humming noise seems to be coming from within the control centre?

hi. I have a a SCS custom built spa with a Balboa vs 500 control centre. When I turn on the jets,There is a loud click in the control centre and then a continuous humming noise but the jets are not working in the spa. It will continue to hum until I press the jet button off or it will eventually trip the jets but the power to the spa stays on.
