Jmoore3030 Posted November 25, 2021 Report Share Posted November 25, 2021 My Hydropool Serenity 5000 after running for 30 minutes (works perfect) trips the main 100 amp breaker feeding my sub panel where my spa is fed from? Seems like it’s calling for another pump to come on it something with a short in it? I haven’t tried cleaning the filter yet, just thought of it tonight. can you help????

CanadianSpaTech Posted November 25, 2021 Report Share Posted November 25, 2021 So it's not tripping the GFCI but the main house power? Start by disconnecting anything not required from the spa... ozone, stereo power supply, pump 2, blower and pump 1 if the spa uses a circulation pump and try to run it and see if it holds. If it holds start reconnecting things one at a time until it trips again. If it is still tripping disconnect the heater from the circuit board and try it again. Post photos of the circuit board and the schematic on the inside cover if there is one so we can see how it looks and is wired. Quote Link to comment Share on other sites More sharing options...
Jmoore3030 Posted November 25, 2021 Author Report Share Posted November 25, 2021 Doesn’t trip the GFCI Spa Pack, doesn’t trip the 40amp supply, doesn’t trip the 100amp main in the sub panel, trips the 100 amp in the main house panel. I changed it out today cause I thought the breaker was faulty and it did it again. Spa starts up and runs fine for 30 minutes. Took the spa from 47F to 51F and then tripped. I didn’t time it exactly (unsure if something in the circuitry is being called for and then it trips. I’m an electrician so I’m taking my Ammeter to the cottage hopefully tomorrow and going to trace everything up, take notes and times everything occurs.

I'd be checking all the wire connections and make sure there is nothing loose. Had a spa this week that would run for 5, 10 sometimes 20 mins then trip. Turned out one of the hot connection from the spa into the GFCI was loose and overheating. Let us know what you find Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted November 26, 2021 Report Share Posted November 26, 2021 What else is in the sub-panel? Sounds like you are pulling too many amps. 1 Quote Link to comment Share on other sites More sharing options...
