Hello everyone. This one is weird for me. I've worked on my own tubs for about 6 years now and have mid-level electrician experience (ran 220 lines, can test with various circuit testers, replaced breakers and motors) I found the GFI tripped and it refused to reset. Disconnected the tub, opened the main breaker, and it physically could not be reset. The breaker was about three years old. We have had power issues, brown outs and power loss due to weather. Maybe even a close lightening strike. I assumed the breaker was bad and replaced it. The tub is a 4 year old Jacuzzi J-235 set up in the 50hz mode. No circulator pump so pump 1 runs in low to heat. There isn't any signs of water leakage anywhere around the tub. After replacement, the tub powered up fine and began reheating. I checked back the next day and the new GFI was tripped. I re-set it, everything powered up fine and it began heating again. I checked back a few hours later, tub temp around 90 and still going well. Checked back the next morning and the GFI was tripped again. The short version is that the tub appears to heat up to around 100F and then trips the GFI breaker. I tested the heater and the resistance was in spec. I replaced it anyway with the same rated heater but in titanium. I isolated the flow sensor and temperature sensor that are in line with the heater and the breaker still trips. I disconnected the UV sanitizer, still trips. The temp sensor and over-temp sensor are spliced together at the plug, so if I disconnect them from the board I get the temp sensor failure error and the heater wont' come on. - not sure if there is a way to test them individually without cutting wires. I can run the pumps in all speeds and it runs fine. In the 50hz mode the heater turns off if both pumps are in high at the same time. I checked the connections in the control panel, the main line black wire wasn't in all the way, just up to the lug but not all the way in the cradle. I fixed that, turned he temperature set point down to 98 and turned it on. It ran for two days so I though I had it fixed. Turned the temp up to 100, three hours later the breaker was tripped. The pumps do not run in high speed unless I select it so I'm guessing the low speed pump is tripping the breaker on overload when the water temp gets high enough. Is there a way to test this? Can I wire the high speed up to the low speed supply lug and let it run to see what happens without damaging the circuit board? Any other ideas? Thank you for any help! R0M0

2001 Hot Springs Grandee in near perfect condition used daily. Again, tube is in excellent condition. Has been used daily since new. Have replaced normal stuff over years to include circ pump, main pump impellors, jets, etc... Recently main heater 30AMP GCFI has started tripping after hours or days. I cannot tell you exact circumstances that trip the GCFI. It seems always to happen when tub is open and jets are turned on (requiring heating mode). I have replaced IN ORDER : 30AMP GCFI , HEATING ELEMENT , HEATER PCB CONTROL BOARD This is a standard HOT SPRING setup so has subpanel with a 30AMP GCFI breaker for the heater and a 20AMP GCFI breaker for the tube pumps/control board. I have NOT used a meter to measure AMP draw of the heater yet. Just seems hard to believe new heater is bad. AND, of course, maybe new GCFI is bad also. ?!?! The tub acts normally when first turned on. Without running jets, the tub will heat up to EXAMPLE 102 within hours. But after several days heater GFI will be tripped. OR.... if you run tub jets with top open, GFI will trip. ALSO.... circulation pump appears normal and filters clean. I have the side "water-fall" option that lets you see the recirc pump water flow. Also, I do not get the HI-LIMIT flashing light and tub shut-down if recirc pump is low flow. QUESTION: I DO NOT FEEL the high heat flow out of the bottom vent of the tub like normal when you have jets running. Is the heater in these tubs ONE heat mode ? Off / ON. Or is there a HI / LOW mode? APPRECIATE THOUGHTS.

my 7yr old Bullfrog is tripping again. About 2wks ago we were in the tub for about 2hrs and the gfi tripped. Although we replace the GFI last year, I figured that was the easiest fix. When it happened again after using it for about the same time I decided to replace the heating element (which I replaced 2yrs ago). The tub runs fine, standard mode. But last night, after 2hrs of use, my tub is trippen again! I don't know where to go from here, without spending a butt-load of cash calling "the man". FYI: I also replaced the pump 1.5 yrs ago. HELP PLEASE!?

Late last year we took delivery of an Artesian Kona Elite spa (2 5HP main pumps). The spa was wired to a 50A GFI breaker disconnect in accordance with the dealers' instructions. The disconnect was tied to a 60A breaker in the main panel. We immediately ran into problems with the spa sporadically tripping the breaker, Sometimes it was in the first 15 minute cycle, other times it would wait until the third 15 minute cycle. Ordinarily we would bathe for about 30 minutes and wouldn't have any trouble. On average it would trip every 3-4 weeks one way or the other. The technicians were out numerous times. Both main pumps were replaced. The heater was replaced. The circulation pump was replaced. The pack was programmed to not run the heater when Pump #2 was energized. None of these resolved the problem. Ultimately we replaced the 50A GFI with a 60A GFI breaker (tied to a 70A breaker in the main panel) a little over a month ago The higher amperage breaker was certainly helpful - and in hindsight probably should have been the FIRST corrective measure - but even with that change a few days ago the breaker tripped. That said, at the point when it tripped the spa had been running continuously for about an hour. The spa was unoccupied for the first 15 minute cycle, which we initiated with the cover open because the water was too hot (a filtration cycle issue, discussed separately). We were in the spa for most of 3 cycles, and the spa tripped as the pumps were being turned off before we exited. Given that information, I have a question about expectations. The engineer in me wants to think that the design of the system should allow the spa to operate continuously, as it might be were it in a commercial setting (e.g., hotel setting with frequent bathers). (1) Does anyone have any insight into what is reasonable to expect in terms of continuous operation with both pumps and the heater operating? (2) The same question, if the heater wasn't energized while the pumps were running? (3) Is a spa designed to only operate continuously for a certain period of time? Thank you!

We have a 2002 Sundance Cameo that stated to trip the 240 GFI every few days. Since I have a 'time of use' electricity service, the spa is in 'Economy mode' so it only heats up during the cleaning cycles. I set the cleaning cycles to run during the night (cheaper electricity) so that when I get into the spa ( ~6 am) the spa is at the desired temp (~100f) The GFI trips sometimes during the night... every few days..... It Never trips while using the spa with all 4 consumers on (circulating pump, big motor, the two speed pump and air blower going) Things I did so far. 1) Ozone generator was >5 years old so I replace it. ---> No help 2) Circulating pump was 13 years old so I replaced it with a more efficient one --> No help 3) Heater element was 13 years old so I replaced it --> No help GFI test button in the main panel work well --- H E L P -- What should I do next ?

Hello folks, hoping to get some help. Running a spa pack with air switches, 2 speed pump, the slower speed runs while the tub is heating up, then kicks off when it hits the desired temp (at full setting on the spa pack usually between 102 and 105 degrees f.), then kicking back on and off as the thermostat dictates. The Problem: The spa keeps tripping the GFI. As far as I can tell from monitoring the situation, it's happening right when the water hits the desired temp and the pump shuts back off from the low speed. I had an electrician friend test the GFI and he says it's fine at this point. happy to answer any specifics. much thanks in advance. Ajax.

Newbie here needs help, or advice. I have a down east spa with gfi problems. It was all working fine untill I drained and cleaned/refilled. When I powered it up @ the gfi panel, it started, got to the prime and then triped the gfi. I tried it again and it imeadiatly triped. I then replaced the gfi. To be sure that was good, it triped imeadiatly. All fuses are good, and I tried with all pumps and the ozone, light Ect. Unplugged, and the gfi still triped. I then tried the whole system with a non gfi breaker, then everything powers up normal. Any ideas? WHAT GIVES!! Is the board bad, how do I check and find a power leak to ground? Al
