WE have a 2.5 year old Jacuzzi J-210 hot tub that plugs into an outside outlet that is a GFI; power has been shutting down; when we tap the plug and reinsert it, the spa power returns. Why is this?

outside receptacles (plug) are GFCI m Some brands do not work with power tools

Have you checked the outside plug? Next to the outside kitchen, It should be there. On my RV I have one next to the bathroom and outside.

Sounds like the heating element has gone out again. Once you reset the circuit breaker and the tub turns on it will start to circulate the water. This usually runs like this for about 2 mins and then the tub will recognize it is cold and send power to the heater. If the element is back at that point it will blow the circuit breaker.
If this circuit breaker pops as soon as you turn it on then you most likely have a bad circuit board.

#1. DO NOT GET INTO TUB FULL OF WATER WITH A GROUND FAULT.
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.

You will need to have a technician from the store you purchased it from install a new switch.

To be up to code, you should have a GFI for your Jacuzzi to plug into and a GFI circuit breaker dedicated only for your Jacuzzi. I

If you already have it, that's great, but if not check with an electrician for installation.

mine did the same thing. the tub is plugged into a ground fault interupter (gfi) plug. hit the reset button. if this doesn't work, check the circuit the gfi is on, sometimes they are on the same circuit as the plugs at the sink. check them for reset also. if this fails, on the motor of the tub, there should be a reset button. try to reset it. OH first make sure the breaker has not been tripped.

Your Jacuzzi should be connected to a large GFI breaker. If it pops as soon as you turn something on, there is an imbalance between the legs supplying the power to your device. When my (small "J") jacuzzi (at about age 15) did this, I discovered a small leak that had dripped onto the circuit board and had left a deposit causing a "short". I was able to clean the deposit off of the board physically, I fixed the leak and return my tub to service.

The GFI is very sensitive and for good reason. It protects you from dangerous electric voltages, even though the danger is low.

hello, if you plug the compressor into a none gfi outlet does the compressor still cut off ? it could be one a short in your compressor causing the gfi to trip our your gfi has a ground try the compressor in a diffrent outlet, when you use any other electronic equipment on the gfi does it still trip ? if you use the compressor in a diffrent outlet that's none gfi this should sholve your problem most likely a bad gfi outlet or the compressor is drawing to much amp's.

If it has the little oval off/on button, it sounds like the control box or off/on button is bad. If you have access to the pump assembly, follow the pump power cord to the little black box (zip tied to a tube up high), this black box has a small cable that goes to the off/on button. unplug the pump from the box and plug the pump into the power outlet. it should run continuously. If it runs, you need a new control box or /offon button. Buy the off/on button first, as this button is prone to water getting into it, and costs less than the control box.

try putting it in non gfi outlet not supposed to use one in major appliances as everything grounds to body of unit
