I have a spa berry 2 person hot tub. Tried resetting it but as soon as I let go of the reset button it trips the breaker. Can't get it to stay on. Tub is 4 yrs old. Where do we start?

if your hot tub is tripping the breaker, it could be due to a worn out ground fault circuit interrupter (GFCI) breaker, which is responsible for preventing electrical surges. You can try flipping the breaker to see if it trips again. If it does, then you may need to replace the breaker.

Another possible cause of the problem could be loose electrical connections in your hot tub . This can lead to power fluctuations that cause your hot tub circuit breaker to trip. Professional electricians can inspect your hot tub and tighten any connections that are loose, which should fix the circuit breaker problem.

If your spa is not receiving power, you should check your home's circuit breaker to ensure that it's not tripped . Reset the circuit breaker if it's tripped to restore power to the spa. If the circuit breaker keeps tripping, it may be an indication of an electrical problem, and you should call a professional electrician to diagnose and fix the issue

bad plug or broken wire replace

Because it is a GFCI. Try making sure that the grounds are all good. Maybe go the extra step of putting in grounding rods into the ground and grounding to the unit. These are just guesses.

#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.

I am assuming this is a GFCI circuit breaker? If it is it will have a "test" button on the breaker. When you say "jets" i'm assuming you mean when you turn on the blower to make the air bubbles? It could be you have a problem with the blower motor. When you start the blower, it trips the breaker. Be sure the blower is in off position when you reset the breaker. The most common fault though on a spa/hot tub is with the heater. If the element goes bad, and current flows to ground, it will trip the GFCI breaker. Again try and turn all functions off. Reset breaker, and then turn on one at a time till the breaker trips. First the pump, then the heat, then the blower.

Sounds like your controller has sustained damage. You need to have a professional inspect it to determine what has gone wrong.

Breakers can grow weak---replace with new breaker.

sometimes gfi outlets go bad and trip try testing with a heavy draw machine in it or just replace it and see if this fixes the problem

Check at the plug in if it has a normal plug like in your home first. Should be a set of buttons there, called a GFI. One is test, and the other reset.Push reset to see if spa comes on. Most spas dont have an actual on button. Check breaker box for popped breaker also, maybe tub is having problems, and needs a service call. Also larger tubs ussually jave a gfi or fuse box outside, close to tub. Kirk
