I have a Kohler spa tub. I want to change the air switch on the top of a Kohler Proflex #1157 motor. I cannot seem to figure out how to get the top of the switch off. I cannot find any screw heads.

I don't know this specific tub, but here's the pictoral. The button (90105) should come out of its base, held by friction of O ring. This should allow you to disconnect the pressure line. If you are looking to replace the complete assembly, likely you will need a basin wrench to reach nut (65157).

How do I change jets in bathtub?


Do you wish to change the jets in the tub or just the trim?

If you just want to change the trim then you need to go the your local Kohler showroom and they can match up the correct replacements for you.

Kohler led lighting and jacuzzi motor + jets stopped working but automatic line clearing air still blows when tub is emptied.


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.

The air switch on my Kohler whirlpool tub, when depressed will not start the motor. However, if I take the plastic hose off the switch and blow into it, the motor starts fine. I've replaced the ai


There are Air Switches (at the motor or control box) and Air buttons (on the spa/bath side). The vinyl tube between them is the only other component to the 'switching' on/off a hole in the tube may cause this problem.
The air switch has a diaphragm which is activated by the air in the tube when the button is pressed. If the air pressure is not sufficient the switch will not operate.
As you've replaced your Air button, you might want to change the tubing and either adjust the Air Switch or replace it. The switch only needs 1-5psi to activate so the pressure from you blowing into the tube can damage the diaphragm in the switch.

When you depress the air presure butoon on the kohler whirpool tub a clicking sound is heard but the motor does not run. There nis powewr to the receptacle that the pump/motor is connected to.


What you need is a new air switch for the back of the motor. The air tubing connects to it on the motor. that is probably what is clicking when you push the air button on the top of the tub. Once you change that air switch you will be back in HOT WATER !!
Should be a TBS-310 or TBS-301 latching air switch is the one you need. Either of those models will work in a Kohler pump.

Where to buy a Kohler air switch and air button?


Most of the control buttons on a tub are not electrical. These buttons are connected to an air line that runs to the motor. Sometimes an aggressive button push can literally blow the air line right off of the bottom of the button.
This problem is as easy to fix as it sounds. Find the loose air line and push it back onto the button. You will need to open up your access panel. Bring a flashlight.
Be sure to check the connection at the motor too. Good luck

I have a kohler jetted tub and i am having a problem with the air switch. sometimes it works, sometimes it doesnt. sometimes i will have to hit it several times before it works. sometimes it shuts off then...


First, disconnect the air hosing from the back of the pump. Reconnect a new vinyl hose to the back of the pump, and blow into the other end. If your pump turns on/off by doing this, see 'A," if not, see "B."

A. The electronic switch in the pump is good, and there is a problem with the air switch or vinyl tubing. The vinyl tubing could be kinked or the air bellows has failed.

B. The electronic switch in the pump is bad, the capacitor is bad, or some other electronic part of the pump is bad. Buying a capacitor or an electronic switch is of course a cheaper fix than to replace the entire pump.

Hope that helps.

Kohler bathtub spa does not work at all


If the air tube is still connected to the air button on the side of the tub and you are pushing it with no results then either the motor is no good, the air button is no good or the air switch in the box is no good.
process of elimination, start with the pump. take the switch off the motor or out of the box and make sure you can get the motor to come on. If the motor comes on then move to the air switch and hook it back up and see if you can blow into the air switch with a new air button or a straw and see if the switch will activate the pump. if it does then you most likely have a bad air button ($12). If you cannot get it to activate the pump then the air switch is bad ($21).

Kohler bathtub spa does not work at all


you need to see if there is power to the pump 1st, there may be a switch somewhere thats not been switched on or it may have tripped out so check that. the air pressure switch maybe faulty or the plastic hose may have even come away from the switch.think of the basics 1st then look deeper, if you have power at the pump then it can only be the switch or worse case scenario a new pump.
you might have to remove the bath panel to gain access to the pump better?
