Hot tub pump tripping GFCI
« on: May 16, 2018, 08:41:21 am »
I think I narrowed down my GFCI tripping problem with my 2016 caldera vanto.  The tub was tripping the breaker randomly every week or two, but worked perfectly fine.  I unplugged pump 2 (the one speed pump) and have let it sit a number of weeks and it hasn't tripped (the other pump was already replaced under warranty for a leak). 

So - seeing as pumps are $350-450, is there anything I can do to fix it?  It doesn't appear to be leaking anywhere.  Why would it randomly trip the GFCI when the tub is not in use, but I can use both pumps as much as I wanted when I'm actually using the tub without it tripping.  Seems odd.... All the wiring looks fine..nothing loose or corroded that I can see

I guess I could plug it back in and run some electrical tests on it, yea?  making sure amps/volts, etc are correct.  It doesn't make any funny sounds or anything. Fires right up when started.

 About the only thing you could really change is the capacitor.  Did you plug the pump back in and run for a week to see if it trips again?

Sadly, and as always, I may have spoke to soon. After about 2.5 weeks of it being unplugged I came home today and it had tripped. Now it did storm and lose power today so maybe that caused it?  Hoping that's the case but I can't  see the parallel. Power  has flickered in storms before and it hasn't tripped...

 Honestly I would say it could very well have been the storm.    Considering it hadn't tripped for 2 plus weeks, didn't it usually trip before that time frame when the pump was hooked up?

Hard to say..sometimes it would only take a week, sometime two. Guess I'll just restart the testing phase and hope the power doesn't go out again. Breaker went to the tripped position, not completely off...if that matters. I always thought middle meant it had a ground fault and completely off meant it was overloaded

If it's a 2016 spa isn't still under warranty?

No, its not. about 2 or 3 months out of it.  Had the primary pump replaced under warranty while it was happening in hopes that it would fix it as it was visibly leaking.  It lasted for a few weeks then tripped, so he came back and actually that visit itself was not under warranty (but they didn't charge) and he tried to do more troubleshooting but everything was working perfectly.  It's impossible to replicate, so its damn near impossible to troubleshoot.

Like I said, I guess I just wait a few more weeks and see if it trips again on a day where there is no power outages/bad storms

It certainly sounds like pump 2.  I bet if you ask nicely they will hook you up.  I know that if I have a customer who's a month or 2 out of warranty we can get authorization from the factory to cover things.  Caldera is a good company and I bet they'd do it.  If the dealer won't, call the factory direct.  Maybe you can just get them to send you a pump and you swap it yourself.

its been well over a month since they've been here.  I am just thankful they didnt bill me for the last trip that was unknowingly out of warranty.  I think there still needs to be some time before proving its pump 2 since I cant tell if the last trip was due to power outage or not..at that time itll be three + months out of warranty.  At this point, i dont even care about the cost (i can install the pump myself), i just want to know what the problem is and fix it.

If he replaced the pump and that didn't fix it, then your problem that was reported while under warranty should still be under warranty.  I'm sure they could talk to the manufacturer and explain the situation.
