I've got a Leisure Bay, Model: G1515CLSSO-H, MFG date: 11/20/1995, Volts: 120/240. I am running it in the 240 mode. (Dedicated circuit)
We have not used this spa in 2 years because of a leak from the pump. Had I known that it was a simple and quick replacement of the wet end, this would have been fixed a long time ago. Anyway, 2 years ago, I re-plumbed approx. 25% of piping and when I got done found that I was still losing water and determined it was from the pump. I just this weekend bought a new wet end and replaced the old one. While I had it out, I connected power to the motor and it ran great, no rubbing, no noise. After hooking everything back up filling the hot tub for a "flush/filter" run there was quite a bit of "chattering" coming from the limit contactor. I'm thinking that this is maybe a case of oxidation build up and will cease after running a while. I allow the tub to run 10 minutes, the heater light is on and I can feel warm water coming from inlet from circulator. I drain and refill, add chemicals, install new filter then start. Everything is working; heater, circulating pump, jet motor & pump, air blower. The chattering is still present. This time, after 7-10 minutes, the main pump motor kicks out. Heater/circulator pump still working, blower motor. I felt of the main pump motor and it's extremely hot. I turn the current off via the air switch and while I'm thinking this thing over, 3-4 minutes, I hear a click from the motor. I pressed the "jet" air switch and the jets start again and run a couple of minutes before kicking out again. I uploaded pics of the wiring. I notice that there are a couple of places where you can see evidence of exessive heat on the wiring. I don't mind replacing anything that I need to... but I'd appreciate any suggestions regarding testing these circuits. I've got my handy-dandy fluke ready. I also do not mind calling for the tech from where I bought the hot tub if that's what I need to do, but you know how us fix-it-uppers are.
Thanks.
