Kohler whirlpool will not shut off and sounds like about to blow

Air Switch Repair
It sounds like you have a bad air switch located in your motor.
The air switch is what the air hose connects to on the back of the motor or on the box on top of the motor. The other end of the air hose is connected to the air button on the lip of the tub.
This is a latching air switch and when you push the air button it latches to send power to the motor. When the air button is pushed again it opens the latch in the air switch and stops power going to the motor shutting it off.

When a bath pump turns on but does not move any water it is usually because there is an Air Lock and needs to be released.Try this.

• Fill the tub with water
• Turn the pump on
• Unthread the discharge pump union until water starts to squirt out
• when this happens you should hear a big 'swoosh'

if the bath pump starts to discharge water through the jets then you have solved the problem.

The workings of a bath jet...From the inside of the Bath there is a wall fitting that threads from the inside of the tub into the jet body located on the outside wall of the tub.
If the jet is leaking at this point behind the tub then you should take the wall fitting out of the tub and put a small bead of 100% RTV silicone around the flange of the wall fitting and reinstall it.
If however, the leak is from the PVC piping going into the jet then you will need to replace the jet.

This is an automatic feature to dry out the pipes and prevent mold. The next time you turn on the pump after leaving these tubs for a few weeks you get lots of black **** in the water and this is what this feature prevents. Sounds like the tub is working fine :)

no not really the only way to fix it right is to open up the walls. this is a common problem with these units, the best thing you can do is contact the manufacture who made it and ask them what to do.

Check for an air switch at your local hot tub store

take the old one in so they can match it up to a new one

When you say turns off, is it tripping the safety circuit?

Most Kohler tubs have a water sensor or water level sensor. Is this an air bath tub (holes in the floor)? or a jetted tub? If it is an air bath, the tub will purge after using it 15 to 30 minutes ater it is drained. If it is programable it will come on every 24 hours if it has been programmed. If it is a jetted tub, there may have been water on the sensor and caused it to start up. If it is a single on/off button the switch could have gotten water and caused it to start up, or there is a problem with the control box. It usually will not start a fire if it comes on, most of the newer pumps have run dry seals. If you leave the house for vacation or weekends, I would advise unplugging the tub or turning off the breaker.
