What kinda breaker do i need for an american standard jacuzzi with 125 btus

no reset on motor ( that would not cause breaker to trip, suspect heating element, or motor is bad.

Trey, motor or pump is seized, have tech. take a look and repair.

In my case I took the motor out and used a screw driver to turn the impeller in the front of the pump and the fins inthe back. Put it back together and it worked. I then used 2 tablesoons of dishwashing detergent and 1/2 cup bleach and ran it for 20 minutes to clean and degrease the impellers

It is tripping for one of two reasons. Either the a/c unit is pulling too many amps or the breaker is weak. If you have an amp meter then check the amp draw on you a/c, if it is pulling more than 24 amps then you need to have it serviced. If it is not pulling that many then you have a weak breaker and need to replace it.

you will have to phone a local Jacuzzi Bathtub dealer in your area to ask that question.

check the air tubing coming off the back of the motor. that tubing should connect from the air switch on the motor to the bottom of the air button on the top of your tub.
if it is not connected then it will never turn on.

sounds like a bad capacitor or a bad spot on the motor. either way you will need a new pump.
couple of sources for bath pumps for you.

First thing to consider is size of Load.
Leviton countdown-timer Load rating is 1800 Watt, 120Volt.
Look inside Jacuzzi at rating plate on motor.
Rating plate on motor should give Volts, Watts and Amps.
Formula Volts x Amps = Watts.
Sometimes motor shows VA which is Watts
Is Jacuzzi on 240Volt breaker or 120V breaker?
Leviton countdown timer is not for 240V load.

A) If 120Volt electric Load checks out, here's how to wire timer if 1 cable enter box.
Timer-black-wire connects to jacuzzi-black
Timer-white-wire connects to ground.
Timer-green connects to ground.
Timer-red connects to jacuzzi-blue.

B) Here's how to wire timer if 2 cables enter box.
120Volt cable coming from breaker box has black, white and bare copper wire.
Timer-black-wire connects to black-wire-from-breaker
Timer-white-wire connects to white-wire-from-breaker-box.
Timer-green and jacuzzi-ground connect to ground

Timer-red-wire connects to jacuzzi-black-wire.

Jacuzzi-blue-wire connects to white.
I am puzzled why this wire is blue if circuit is 120Volt.

is this a new install? if so you may need to adjust the air intake. Or if you have kids they may have messed with the settings. If the air is closed all the way off....no bubbles.

check for power at plug in if power your vacume switch is probably out replace switch.
