Thanks for all the replies guys. I still can't figure this darn thing out. I inherited the spa with a home purchase and I'm going to guess it's probably 30 years old? There isn't any type of LCD display, the buttons are just plunger buttons. One turns the jets on slow, the other turns the jets on full blast, and the third is to the light. The heater, pump, blower and intermatic timer are located in our garage.
FWIW, my spa pump has been leaking lately, to the point where i had to lay down drip pans and drain every other week. When I first realized the pump was not turning off, i had a lot of water around the area of the garage where everything was located. Since then the leak has intensified. It used to just leak when the pump was running, but now it leaks constantly, to the point where I have to drain the drip pans almost every week, and I haven't ran the pump once.
I have no idea what to do next, the pump still will not operate with the timer and runs constantly anytime I flip the breaker. I can provide photo's if that might help anyone diagnose?
