This should be simple ...
1.shut off the power
2.disconnect wires to heating element
3. turn power back on and see if it works if so replace heating element 45-95 dollars

if it still trips unplug all the cables from the pumps blower ozonators and see if it runs now,,,, if so plug each cable back (one at a time) until it trips again.if it trips that the problem pump etc.

99 percent of the the time its not the gfi its a device that is wet or shorted out ..Try everything else before replacing the gfi

My hot tub works for about 20 mins and clicks the GFI off. Then I reset the GFI and the spa comes on for about 7 mns and trips the GFI again. Is this my heater doing this?

Easy way to test for the heater issue is to disconnect the heater from the board. Disconnect both leads from board and let the spa call for heat. There is also a chance the GFI breaker is bad however most times the heater fails and the breaker is doing its job.

Need to see wiring diagram on control panel in apa

Most common reason a gfi trips is the heater or blower have failed!
Unplug each one, one at a time...
whatever is unplugged/disconnected from board and the gfi stays on, that piece is the bad item and needs repair/replacement.

Sta-rite heater is about a year old. It worked well up until a week ago. It now trips the gfi breaker. I swapped out the breaker and it trips that too. If I disconnect the exhaust fan, the heater powe

Something in the electrical system supplied by the GFI breaker has a ground fault. The current to ground required to trip a GFI is very little such that dampness on any electrical connection can trip it. This is especially true with motors that have a lot of fine wires in the windings and are open to allow cooling.
Hard water and pool chemicals all are worse than condensation from the air because of their ionic nature.
If the same GFI powers the pump it is what I would suspect first. Your question got cut off before the result of the fan disconnect which if disconnected didn't trip the GFI, is probably the problem. But you should open whatever you can access containing electrical components and make sure everything is dry

Hot gfi keeps tripping

You didn't specify how your pool is set up, but the GFI tripping means you have too much power, too many devices plugged into it. I think you need an electrician, just to be safe.

Emerald Vantage Hot Tub Dead

if your GFI trips soon after the spa goes through the purge cycle then you need a new heater.
Yes the heater can develop a dead short and it causes the GFI to trip when power is sent to the heater.

What's youI just wired in my J-300 Jacuzzi hot tub. The GFI trips every time I reset it. I took the GFI out of the equation and the tub runs fine, does not trip the breaker at the main breaker box

2. There is a short. You need to get multimeter and start checking each part for current running to ground wire.
3) Power is ON. Connect power without GFCI.
4) Tape tester leads to wood sticks to keep hands away from power.
5) Do not touch anything directly or you will become the ground rod.
6) Ground wire must be present, and bonded back to main panel box.
7) Do not sit or touch directly on cement or bare ground. Do not touch or lean into anything made of metal.
8) Body and parts must be on sheet of plywood, or similar non-conductive dry surface.
9) Test each part with spa, but also test electric line coming from main box.
10) GFCI will also trip with any fault detected on line. So the wire coming to spa may have the fault.
11) Add a new dedicated line from main box to spa.

I have a freeflow legend hot tub. the gfi was tripping and i found the heating element was bad. i replaced the heater element now when i power up the tub a circuit breaker trips on the board and nothing...

It sounds like there may be a short in it causing the breaker to trip. I would disconnect the wires from the new element, tape them up and test for the problem again. If it still trips it is not related to the heater element. If it still trips it is not related to the heater element and therefore additional diagnostics need to be used to find out what is is wrong.

My pump and heater had been working fine. Now the GFI is tripping. I reset it and start the pump and when I start the heater it trips the GFI again.

Gfi's will trip when there is a very small variance in the power across the circuit.
Check all the grounding connections, and all the terminal connections to make sure they are tight and secure.
Also it would be wise to check the GFI with a separate tester. They can malfunction, you can get a testing plug at a local hardware. It has a plug with lights on it and a test push button. Very handy to have in your tool arsenal as well.
If it checks out, then it's very likely it's doing its job correctly and protecting you from a worse issue.
If you cannot check these wirings, have a pro help you out.... better to spend a little than get shocked while in the tub...
