My jacuzzi tub motor will hum but does not run. I tried filling it up and plunging water into the jets. How can I check the motor. Is the motor located under the pushbutton on the tub? The motor is enclosed.
I had this same problem. I looked at the motor, and on one end (the end opposite where the water comes out) there is a hole in the middle. In that hole is a regular screw tip, which can be used to turn the motor. I filled the tub, inserted a slotted regular screwdriver and turned it about 8 times clockwise, then 8 times counterclockwise. You should see the whole motor turn. Doing this loosened it up, and then it started.
Once it started, all kinds or residue came out, which was probably why it had stopped working. I hadn't used it for a while.
After getting it running I'm going to run some cleaning solution through it, and make sure I run it more often to prevent this in the future.
It is also worth noting that my tub isn't jacuzzi, and it is a GE motor. But I'm guessing the problem is the same - you need to get the motor turned a few times. Just like unsticking a garbage disposal.
On second look, this didn't fix my problem, as there is now some water leaking. Did I break it? Was it already leaking? I don't know.
Fixed my problem.

Turning the motor manually (with a wrench in my case (Jacuzzi Magnum Plus)) worked for me, now the pump is pumping happily away, thank you!
There is a capacitor in the motoe (easily replacable, 10uF) that goes bad. When you replace this the motor will start as norma.
If the motor hums, it is seized and needs to be replaced. Call a reputable repair tech to make the necessary repairs.
David, What I have found is that when a motor seizes, it is the beginning of the end. I have freed a few by turning the screwdriver slot in the back. What I have found is that water found it's way in to the motor through the pump, then you have water leaking where the pump and motor are connected. I have pulled the pumps apart and replaced the seals. This is not difficult to do but requires some knowledge of the pump and the correct seals to be replaced. Buy a rebuilt pump/motor and throw out the old one. Nice try though, If it was mine, I would have done the same thing to see how long it would last before it leaked or quit.

With a small Phillips screwdriver, I removed the intake screen, inserted a water hose, and wrapped a rag around the opening to prevent backflow. I turned on the water, waited for the pressure to build, and turned on the pump. It started right up. So, I turned it off, replaced the intake screen, and the system works as advertised.

I found an easy way to fix my Jacuzzi tub when it just hums. I pop out one of the jets closest to the motor, fill the tub, and use a plunger on the jet. I keep plunging and then press the power button on. If it hums I turn it off and plung again. It usually only takes a few tries before it works.
