I just recently acquired a Cal Spas hot tub. It has a label on it that states C3001 and a year 1997. When I open the control box, it has a wiring diagram with Balboa on it. Anyway, when I first turned it on, everything was working. The next day, the jets would not come on: no sound or activity. The heater and the ozonator seem to work since the water is at the temperature that I set it and the water circulates every so often. BTW, the night before, I saw this icon on the control panel that looked like a key hole. I might have pressed that a few times trying to figure out what it was. Did I somehow lock the control panel? Does anybody have a user's manual for this model? Does anybody know how to lock and unlock the control panel? Any other ideas about why the jets won't work?

Thanks in advance for any help.
