Blower turns off quickly

[ajw22]

It should not take a hacked opening if the housing was built for air and water lines.

Did you try running the air and water together with the jets removed?

Ok I ran the blower with the jets out and pump on and no issues, the blower stayed on and air blew out the housings. With the jets out, there is no pressure. So I'm thinking I have the following possible problems:

1. I have the wrong jets

2. I have the jets installed incorrectly. They are screw on jets so hard to get this wrong but my I did something wrong.

3. Too much blower horsepower. When there is pressure or a few of the jets closed, this creates back pressure and blower overheats and goes into protective mode and shuts down. This may make sense because as I drilled a bunch of holes in the 2" pipe to alleviate some pressure the blower ran longer but eventually still shut down.

Maybe all of the above...thoughts? because I'm just using common sense here and have no experience with pools or spas.

Assuming I have the 210-5830 jet body. Does that mean I need one of these model jets below. Can't find much on their website on compatible jets.

210-6040	Adjustable – Caged Style	11.6 lbs.	75
210-8750	Monster – Caged Style (5/16″ – 3/8″ – 7/16″ – ½” Orifice)	8.39 lbs.	50
210-9790	Whirlpool – Caged Style (3/4″ Orifice)	6.05 lbs.	50

We need to find someone who knows what housing that is, why you have the hacked cuts on top, and what are the correct jets. I am at the limit of my knowledge and search capability but will try and get other folks pointed to this thread.

My guess is the jets are not mating properly with the air and water outlets in the housing.

 

[Davie]

sounds good appreciate your time and help with this.

I haven’t plowed through this thread.

Take the blower off the stand pipe & run pump & blower as usual and see if the symptom remains.

Please take a look at the pics in post #17. Trying to understand how housing in wall and jets fit together with water and air lines.

Does the OP has the correct screw in jets?

Also, when I took the jets out, the blower ran fine for about 20 minutes and never shut down. I'm thinking i have the wrong Jets installed and it was blocking the air hole. I'm believe I have housing 210-5830 and I need jet part number 210-6040 jets.

Blowers should have a bypass built in. I thought it should be able to run even if the pipe was completely closed.

Our Spa uses the same jet nozzle by Waterway as shown in post#17 but the jet body on mine looks different from OP. We don't have a motorized blower but water will come out of the blower pipe if I close all the jet nozzles. My guess is, OP is using the wrong jet nozzle for his existing poly jet body assembly.

I have very limited knowledge on this but here's a complete line of poly jet body and jet nozzle assembly that might help.

 

[Davie]

Thanks, I think so too...I've ordered 6 of the older poly jets 210-6040 Waterway 210-6040 Poly Jet Adjustable Jet Internal White

Will keep you posted on the status

It’s fixed!!! It turns out I had two issues.

First issue was the Jets. I definitely had the wrong model jets installed. The correct jets 210-6040 function correctly in my spa.

However even with the new jets installed the 2.0 HP blower was too much power and eventually would overheat and trigger the safety turnoff relay. While I was waiting for the new 1.0 HP blower to show up I decided to drill holes in the down pipe to relieve pressure on the blower. The more holes I drilled the longer the blower would stay on. I ended up drilling eleven small
holes in the pipe and the 2.0 HP would continue to run without shutting down. This confirms I have way too much HP for the distance and jets as in post #7.

In this case bigger is not better! The 1.0 HP is installed with no holes in the down pipe and the blower runs as long as I want it to 1hr and counting.

Hope this helps anyone else with similar issue.

Thanks again for everyones advice in helping me troubleshoot this problem.

Glad you got it figured out. Having multiple problems always makes it more difficult.

I’m curious is your blower glued to the stand pipe?

Interesting. I had not thought of that as the over pressure release.

 

[Davie]

Definitely not glued! It says on the blower do not glue on the warming label.
