Hotspring Moto massage fault - no air

Recommended Posts

I have a 2012 Hotspring Sovereign. My double Moto massage jets has stopped going up and down, and I have narrowed the problem down to the air flow in the moto massage compartment. No air comes out of the nozzle in the Moto Massage compartment.

I have already gone through the following steps:

-Changed the Moto Massage jets ( vertebrae tubes)
-Changed the air hose with manifold
- Turned all control valves in different directions
-Cleaned filters (Tri-X)
- Run the jets with filters off for a couple of minutes
-Checked the air inlet in the service compartment
 

All other jets works fine and are stable

 

Any suggestions from you??

I do recommend checking out the air control valve to that seat. It's likely that you have a misaligned piston in the valve or an obstruction that is preventing air pressure from driving the jet up and down.

Thank you for that. Will I get to the piston by dismantling the valve from the top..? Would appreciate it if you could explain closer how I get "under the hood"

*EDIT*

Found a How-To online. Will try tomorrow. :)

Hi again. I have checked the valve,and compared to the valve next to it,it looks good. When valve is removed,there is no airflow in the "valve hole" no matter what position the Smart Lever is in. 

Any other tips?

Hi, I was wondering of you ever found an answer to your problem?

 I discovered the exact same issue with my single moto massage today. My neck jets (along with everything else that uses air) in that seat work fine, did yours? I was suspecting, since the neck jets worked, it was the air hose from the valve to the MM may have split or came off.  I have not opened the covers to check this out at all, (it's too cold out there today!) However, it would seem to make sense,  that a single air hose would feed both of the dials that control that seat's MM, then individual hoses would go from each dial to the shoulder/ back ports of the MM? Anyone know if my thinking is correct? 

I seldom use the single MM seat, so I may wait till it's warm again to tackle, but would appreciate any guidance.

thank you,

Randy

Hi, I did find the issue, and it was a simple fix.

I popped off the air adj. valve dials (on top of tub, they just pry off) that went to the problem Moto-Massage and using an air compressor with an air blower end, blew air into each one. Bubbles came out if each air jet except for the problem MM. Assuming it was plugged somehow, I then took the air hose off the MM, and stuck the air valve into the jet, holding a towel to help seal around the air hose. This would reverse the usual air flow, and hopefully clear the line. When I released the air, it took a few seconds, but a piece of fuzzy garbage blew out of the removed air valve on top. So somehow, something got sucked in the air line and plugged that line.

So if you have access to an air compressor, it’s an easy fix.

Hope this helps, Randy
