does anyone have a problem with circuit breaker tripping, always after a rain? If so, what is the solution?

Most likely you are getting water intrusion on something electrical, or you may even have a break in your insulation somewhere. This is especially true if you have a GFI (GFCI) breaker. Examine the power cords throughly, and also check for leaks around any junction boxes or cabinets.

I have a very old tub, but it works great. 1984 Oregon Hot Springs Classic.
I keep it in top condition and take excellent care of it. Problem is, we had a storm recently that made the power go on and off several times. I always check the tub when this happens since we are in our freezing weather. Sure enough, all power was off. I check the plug in (I don't know all tech terms here). This is a fat plug in with a test/reset button. It has never hung right in the plug and I used to tape it to the receptacle so no moisture could get it. I haven't done that for about a year though. The entire plug head is covered by a clear cover. I pushed the test and retest button several times..it wasnt that. I checked the circuit breakers for it in the garage, they weren't off. Then I checked the circuit breaker for the tub and it wasn't off. I had almost forgot about the reset buttons inside the tub by the heater and motor area...looked inside there and just the heater reset button had been popped. I pushed that in and it started back up fine. I thought this had solved my problems til Wed. nite. Went out for a tub and noticed the humm wasnt happening. Sure enough, the heater reset button was popped again. All I could do was push it in. I looked over the menagerie of stuff under there and honestly wouldn't know if something was wrong unless it was obvious. I didn't see anything burnt, or wire touching metal or corrosion or any water...I didnt see anything that looked out of the ordinary. I let it heat up and hoped it wouldnt shut off for Thurs. night. Thurs night it was popped again, but the temp hadn't gone down too much. I pushed the stupid button back in again and spent 45 minutes in the tub, heater on and jets on...it stayed on...nothing unusual. this morning...I go out...it's off again.
My question is...should I be resetting it constantly or should I leave it alone? I know it's best to call a tech, but if it's something easy I could just fix myself, I'd rather do that. Thank you for your time.

that reset you are describing is not your GFI breaker. That is your high temperature limit switch, and what is happening is either your high temp limit switch is defective, causing it to trip at a lower temp, or you have a blockage/weak pump/or air pocket in your heater chamber. Your heating element may not be getting enough waterflow to prevent it from overheating. Here's what I would do, keep an eye on the temperature, and make a log. See if it is tripping off at the same temperature each time. If it is, then your high limit is defective. If not, then you have a water flow problem.

I'm going to spend tomorrow really taking a look at all the wires per chargers answer and also do the log like you are saying. If it is turning off at a certain temp, could I possibly just set it lower? Or am I avoiding the lurking problem?

Also, if anyone could recommend an excellent tech in the Portland Oregon area...I would sure appreciate it...I can't find mine..I think he moved on. He was the best..did excellent work and was very fair...and also showed me how things worked that he was working on. Very nice considering all the techs out there working for companys that just want your money as fast as they can get it.

Thanks again!

PS, don't laugh at my spa cover...that is actually how the place that I bought it from made it...I got ripped off. I have to stuff things in the end holes they left. I'll never try to save a buck on covers again.

Yeah I see I forgot to log in when I told you about doing the log... lol Depending on the temperature you like the tub at, you could just keep the temp down below the limit. Say, if it tripps at 104, you could be just as comfy at 102. There is a way to adjust the high limit breakers, but I wouldn't recommend it if you are at all uncomfortable removing an electrical safety device and messing with it. The worst thing that would happen with the limit breaker being left as is, would be that it would fail all together, and you will in most cases just loose heating until it is replaced.
