When a motor is doing this it is overheating. You should replace the motor as soon as you are able to. This could cause more trouble for you soon because the motor is over heating.

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.

First the obvious, most are electrically connected to a ground fault device, ether an outlet or a breaker. BEFORE ADDING WATER, check these out to make sure they are not tripped. Most all tubs have a minimum water level which must be reached before the jets will operate. This is usually a piece of trim located above the depth of the jets. Make sure the tub is filled to cover this part. If you cant identify the water level device fill the tub so that all the jets are covered by an inch or 2. Some tubs have push button switches or touch pads to control the motor, some have touch sensitive trim. There may be some sort of medallion from the maker on the tub, simply touching it will start the tub. Once you get it going most tubs have a built in timer that turns off the pump in 15 - 20 minutes. For more tub time just hit the switch again but keep in mind that extended exposure in a hot tub can mess with your blood pressure and cause you to loose balance or pass out, hence the 20 minute timer.

Most jetted tubs turn off after 20 to 30 minutes. It is a safety feature as well as a thermal protection feature for the motor. I doubt if there is anything wrong with your tub. If you contact the manufacture of the tub, they will most likey confirm what I have said to be what is going on. If it was a hot tub, like the ones used outdoors, this would signify a problem.

Is it a jetted tub, or a air bath tub with holes or jets in the floor? If it has holes or jets in the floor, the control box is bad and needs replaced. If it is a jetted tub, there may be a water level sensor, if so the sensor may be bad causing the tub to turn on.

Sounds as if you may need a new switch to turn the tub on/off. You can find one on our site www.uspartscenter.com
