Whirlpool Jacuzzi with 10 jets one stopped working.

Check under skirt and see if gfci receptacle has tripped. If it has you should call electrician.

If the bubbles are not working on the tub it could be the check valve is stuck closed or the air blower is not working.

if the air blower will not shut off then it will either be the air switch in the blower or the control module that operates the blower will be bad.

LOOK FOR A RESET "RED" BUTTON ON THE MOTOR, PUSH IT IN.

It sounds like the machine uses security-type fasteners, which require special screw bits. You may be able to remove the screws with one of these security bits, such as those sold by Harbor Freight.

When a jetted tub will not turn off it is usually because the air switch in the motor has quit functioning.
A new air switch for your pump costs around $20

I assume you hooked the hose back up to the air switch on the motor.
There will only be a couple of things to check.
Make sure you have a good connection with the air hose to the air switch on the motor. Sounds like maybe the air switch may be bad.
The Air Switch is a latching air switch so if is broken then it won't latch when the air button is pushed.

you will have to look to see where the fitting is to install this heater.
there are two styles of heaters they use (mostly)
In-line pressure heater that installs after the discharge of the pump but before any of the jets.
the in-line Vacuum heater installs before the front of the pump in the suction line.

There is a small nipple on the back of the pump or the black box on top of the pump. This is where the tube attaches from the switch.

Hello. yes you can replace the switch. All of the parts come with instructions. plus you can call the jacuzzi repair technician directly and have him/her talk you through the procedure at 866-905-2289. here is the owner manual in case you don't have one
