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 turns right back on. any suggestions?
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.
