HydroAir LD7 whirlpool bath pump won't turn off with air actuator.

SOURCE: Difference tubs and air baths

whirlpool tub has jets that circulate the water, where an air bath uses bubbles that rise gently from the bottom of the tub. Whirlpools are typically used for therapy, air baths are used for a much gentler experience. Air baths can be used with aromatherapy/essential oils. Both offer a spa-like experience.

First I would remove the switch hose from the pump. Pinch the end of the hose over and hold it in place with a piece of tape. Depress the button and hold. If the button has little to no resistance then there is a hole in the air line which is causing enough air to leak that there is not enough force to activate the switch. If that is not the problem then just consider leaving the switch in the hole on the tub surface but adding a regular wall swich to the wall near the tub. This move the switch action from the tub to the wall. This a really cheap solution compared to getting a new switch mechanism which is what is broken for about $200.

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 would guess there could be one of two problems. First, open the access pannel so you have acces to the motor and air tubes. From your actuator that turns on the jets, there should be a small tube (probably clear) that goes from the actuator to the motor. this tube controls the jets, make sure it is connected, finding the small nipple that this tube connects to on the motor can be difficult and they are often not connected when you buy the tub or come loose during instalation. If that is OK, check to make sure the Air Inlet pipe is not blocked. there should be one (maybe 2 but usually 1) of the large tubes that circle the tub undernieth that is open on one end. It is probably the tube that is the highest off the ground. this should not be connected to anything, it almostt appears that the water would rush out if you don't connect it to something, but that is where the air comes in for the bubbles. good Luck
