I have recently been given 6 man outdoor hot tub...
After re-wiring most of the control panel, I finally have the pump
running and the switch seems to work between low and high speed.
The pump sounds like it is running fine, all valves seem to be open,
but there is no water pumping out of the jets.
Can anyone suggest some troubleshooting steps to find out why?
Is there any way the pump is not working, even though it sounds like
its running between the two speeds?
The jets do not seem to have an on / off option.
Any advice would be greatly appreciated.
Thanks - Matt
GENERALLY, when the water isn't flowing through the pump, there is a message
on the panel that says FLO or FLOW, or a light comes on.
What happens is .......
When the thing is drained, there is an air bubble in the pump. You have to
find the bleeder, turn the pump on, open the bleeder, and let the air out,
or at least until it catches prime.
On mine, I drain the spa into the pool, then refill the spa from the pool so
I don't have to heat up as much water. Any time the spa is drained, the air
bubble phenomenon occurs. On mine, I can turn the pump on and off, and
sometimes it catches prime. Not always, and I have to take off the side
panel and reach in there in all the spider webs and insects and open the
DO NOT let the pump run for long with nothing coming out.
It is an easy fix unless you fry the pump, then you're talking serious.
No biggie once you've done it once.
Also, kill the juice to your spa. Take off the electrical access panel.
There is usually fuses in there. Go get extras. When the thing just won't
work, check the fuses, and change them. If that don't work, then you call
the repairman. No sense calling them out for an $80 call that you can fix
for a buck.
Enjoy your spa. We love ours.
If it is air locked, another way to get the air out of the pump is to
use a garden hose to force some water through the system under
pressure. I can do this on mine through the filter housing, with the
filter removed. Of course, you want to do this with the pump turned
Normally, a spa should self prime. I've drained mine many times over
15 years and only had it get air locked once. Why it happened that one
time, I don't know.
On mine, I need a person with a tiny crooked arm. Using my big ham, I have
to reach in there between pipes, do a ninety at the wrist, then turn the
bleeder with the last 1/2" of my fingertips. One of the bleeders is right
out there, and the other is in a bunch of pipes.
It all depends on your spa.
"That's not normal on a large number of spas. Priming by bleeding is so
easy, it's not worth the effort to argue against doing it, needed or
I'd beg to differ. Why anyone would want to remove screws and an
access cover, then a plug in a pump, every time you change the water if
it's not needed is beyond me. Plus now you have homeowners who may not
even be comfortable with basic safety, inside the spa where you can get
into trouble if you don't know what you're doing. Like letting water
run into the power pack. These are supposed to be simple consumer
friendly units by now. And the ones I've seen have been. There's no
mention in my owners manual of the need to do this. This isn't rocket
science, they should be able to make them so they self prime.

If you are commissioning a spa, you already have the access panel off. I have no
idea what "pump" you are plugging in. The power is OFF to the entire unit while
you are bleeding, which takes less than a minute. This is a matter of loosening
and then tightening a couple of unions so that a little air escapes and water
trickles in. You are correct it isn't rocket science. So why are you trying to
make it sound as if it is?
Do you own a spa?
If the answer is no, please do not go on to the second or subsequent
How can you bleed a spa with the pump off? You need positive pressure to
drive the air out.
Why would anyone in their right brain mind want to break apart a union that
is sealed, and risk creating a problem?
How in the world would one get a pipe wrench into all that tangle of pipes
and wires to break a union loose?
How big are the unions on your spa? Mine are about four inches across the
How long is a pipe wrench that will loosen that big a nut? Or, even, how
big a set of channel locks would that take?
Bleeding spa lines by breaking unions? Sounds as rational as swatting flies
with a sledge hammer.
You folks are describing a spa with a serious <plumbing> design flaw.
There are no bleeders in my spa or my pool and I have never seen a
need for one.
If you have an "air trap" in your plumbing you should have hired a
That would be Catalina Spas, one of the top ten in the world. I believe if
you have no bleeders in your spa, you must have a cheap0 Home Depot special.
Your filter on your pool does not have an air relief valve? How strange.
My spa was field assembled and there are no air traps in the suction
side plumbing. We did that on purpose. You statement about the filter
is pure bullshit. That is on the pressure side of the pump and has
nothing to do with priming problems.
If you have bleed screws in a properly designed spa, that is for
DRAINING the spa, not priming it.
