Well, I spent most of the day working on the hot tub. About 15:00, I had the wiring done and it was filled for the second time...
I turned the power on. Good. Hit the pump. Great! No leaks, after I fixed the first one.
I turned the heater on. There was a loud buzz and it quit working. And so did I. Hell with it, who needs it anyway!
Well, I do, actually. Well, not need it, but I want it. I have it, and I want it to work. So I'll work on it some more tomorrow.
Gotta be something to do with the heater, of course. Something expensive, most probably.
Anyway, I got up at 04:00 this morning, so it's barely after 19:00 and I'm going to bed.
