Just my advice, but please replace your bulbs regularly. Or at least look at it. They don't always fail to light when they need to be changed.
I've taken apart the machine and I was concerned about the wiring for the light. The previous owner didn't replace a bad bulb which caused a lot of resistance and the wiring suffered. The light switch will need some attention as well. I'm going to have to do some wiring there.
The wiring for the motor, the cord and to the foot pedal appear to be fine.
I've disassembled it as far as I think I'm going to. Here she is in the throws of her Super-Deluxe Mega Spa treatment.
