My American standard Jacuzzi tub hums when the button is pushed, but the jets do not turn on

Not normal for that to happen but the jet faces on the two back jets may be turned off or down.
Try turning the face of the jet clockwise and see if you get more water flow out of each jet.

The problem you are experiencing is common to many jetted bathtubs.It is a result of dried bathing water in the tub. There are a couple of solutions to resolve this ongoing problem.

1. Use your tub more frequently as the water will not have time to fester in the pipes.
2. Use a cleaning solution made for cleaning the pipes on jetted bathtubs once every three months.

You find Cleaning and Maintenance Products for jetted tubs at the following website. US Parts Center

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

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.

you have a bad motor - when a motor overheats there is a sensor inside the motor that will shut if down so as to not damage the windings and such. once your tub has cooled down for 10 mins or so it will turn back on. the fact that you can push the button multiple times just means that you are turning the air switch on the back of the motor on/off until you get to the point where the motor has cooled down and will turn back on. if you do not push the air button after the tub shuts down and you finish your bath then when the pump cools down it will come back on because the air switch in the motor is latching i.e. it is either on or off. Since you left it in the on position the motor will come back on once the motor has cooled down.

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.

All the electric power source to all jacuzzi tubs all required to be protected by a "ground fault" device. Have you noticed special wall receptacles in your kitchen and bathroom that have 'test' and 'reset' buttons? There may be a receptacle (or something that looks like a receptacle but without any slots for plugs) near the tub. Push the reset button. If the pump for the tub has an access panel, the device may be behind the panel. And last, the circuit breaker in the main electrical panel may be a ground fault type and needs reset there. Good Luck

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