Re: Air switch not starting pump
Well, the eyeball and cage assembly you refer to here has nothing to do with the pump turning on and off.
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 button on your tub may be bad and not sending enough air to the air switch located on the bath pump. The way to check this is to remove the bath pump and see if you can turn the bath pump on by taking a large straw and blowing into the air switch on the bath pump to see if you can get the bath pump to turn on. If the bath pump comes on then you know you have a bad air button. If you cannot get the bath pump to turn on then remove the air switch and plug the two wires going to the air switch together and then plugging the pump into a power outlet you know has power. If the bath pump comes on then you know you need a new air switch in the motor. If the motor does not come on then you need a new bath pump.
Fill your tub and turn the pump on. Get under the tub down by the pump and while the pump is running, loosen the top pump union until some water starts spurting out. Once you loosen that pump union you should hear a loud swoosh of water kicking through the pump then you can tighten down the pump union.
Is the board getting power, is the control lighting up? Do you see any error codes on the top side control? Improper flow will give you an error code, caused by flow issues or a faulty flow switch. Make sure all gate valves are open and the water can flow freely. If not then check your Hi Limit sensor. This is the overheat safety sensor if it fails the tub will not function at all.
The dr error code is for "dry". Meaning that the control system is not sensing that water is flowing through the heating element.
With a new spa, and you just having drained it , it is probably an air locked pump.
What this means is that you have a small constant circulation pump with not much power, that got ait trapped in it when you drained. When you went to start back up, this "air lock" prevented the pump from fully priming.
Power down the spa at the breaker. Remove the filter element.Stick a garden hose with lots of pressure into the skimmer hole and open the hose valve to let water inject into the skimmer.
Restore power to the spa and check operation.
If after attempting this a few times you still get the code, there is an issue with your flowswitch, or with your circulation pump.
With a brand new spa, id like to hope that you just have an air lock.
Sounds like either the air button on the side of the tub has quit working or the air switch in the back of the motor is not working. Take the pump out. Get a straw, plug the pump into a working power outlet, blow into the straw into the air switch (where the air tubing was connected) on the motor. If the pump comes on/off when blowing into the straw then the air button on the tub is bad. If the pump will not come on or turn off when blowing into the air switch with the straw then the Air Switch is bad.
Issue with Safety Swich Over Flow ...Check for fail connection make shure Tub is empty When your container is full of water the unit wil not power on till you empty the container ...Also check for filter on the back top of the unit it important the filter as to be clean because the unit will over heat then damage the pump inside
There arn't any provisions for ejecting water out of the pumps that i know of. The pipes are installed on the tub so that they will gravity drain back into tub. The pump wouldn't be able to run unless fully submersed in water above the jets, i mean it will but not for long. I would sugest disconnecting elec. to pump until you resolve the issue or else the pump will burn.
-This sounds like some kind of air switch problem. Something is causing the air switch to sense the air pressure excerted through the air hose without the button being pushed. This is the only thing it really could be since the power to the pump goes through this switch. I cant imagine anything else causing this other than a faulty air switch on the pump itself. This would mean the pump would need to be replaced since the air switch is sealed in place at factory. Unless some how, some way, air pressure is increasing in the air hose all by itself, not likely. But check the air hose connections on the pump and the button on the tub, if you can even see it. The hose may be partially attached and any slight movement while partially attached could push air into the switch but thats kind of a long shot. I dont know if a craked or split air hose could cause this to happen but i guess its possible.
-If i had to bet on it i would definatly say the pump switch is defective.

Find the plug for the pump and plug it in ( tub full of water), if the pump works,the problem is in the contol box or switch. if the pump/motor has a plastic tube coming out of a black box, and the pump still does not work when plugged in, it is most likely the air switch connected to that plastic tube on the pump. the switch is avaliable online and not to hard to replace if you are mechanically inclined.
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).
This is a problem common to all whirlpool/air jet style tubs. The pumps become air locked due to the water evaporating from lack of use. All tubs need, and have, SOME means of priming the pump, this is most likely what the problem was, originally, for you. This time in particular you found it to be electrical in nature but for future reference, for you and all who have these style of tubs, I am putting this out there. Some where on the tub, usually along the top edge of the tub is a vent knob that controls the amount of air that the pump is allowed to mix with the water for the jets, usually by closing this valve all the way (tub needs to be full of water of course) and running the pump for a minute or 2, you should be able to get the pump pumping water again, if not you may need to do something else with your particular set-up to get it purged of air, the pumps in jacuzzi tubs are designed to pump water, not air, so if the motor is running but you get no jet action, your most likely air locked and need to prime pump/purge air.
