HI All ... It's a new season and I've got a question right out of the gate! :)

I opened the pool on Saturday and after runing my equipment through it's paces I found an issue. When going into spa mode, the actuator controlling the jets does nothing so I tried testing it with the dipstick and still, no response. However, I hear a faint clicking sound so I know there was some level of activity going on. So, upon removing the cover, I can see that the motor (spindle) turns without issue but doesnt seem to be engaging the underlying gears.

Could this be a micro switch issue? Something with the gear pack? ... I'd love to be able to repair the actuator rather than replace it but I;m not sure how to isolate the problem.

As always, any thoughts or suggestions are greatly appreciated!
 
You have to fully remove it and check the gear assembly beneath the motor. Could be an issue there.

The valves are rebuild able if you wish to spend the time on them. None of the parts are all that expensive. If you plan to rebuild and tinker with them in the future, it’s best to have a spare on hand so you can swap them out quickly.

As a side note - all three of my actuators died this winter. I have two spares so I can replace some of them but I will have to rebuild them all. I’m seriously considering just buying three new ones but not the OEM Pentair CVA’s as they are ridiculously overpriced now that Pentair has moved on to IntelliValves.
 
Thanks for all the feedback!

So, after some thought, I'm actually going to do both ... I ordered the housing with lower gear pack as a starting point to see if that fixes things straight away but will diagnose beyond that if I'm still having issues. However, I do have an actuator on a cleaner line that was installed but is completely inactive due to the fact that the pool company failed to plumb in the booster pump so they gave me a Polaris Cleaner. SInce this is never used, I figured why let it go to waste! So, my plan is to remove the cleaner line actuator and swap it with the actuator on the spa. From there, I'll have the spa actuator working and then be able to breakdown the malfunctioning one and get that working in the event I need a spare.

My question is this ... how complicated is it to configure the position stops when I swap things over from the cleaner line? I ask, because the "normal" position on the spa has the valve partially open (~45 deg) ....

and in spa mode ...

From the manual, I see that it should simply be a matter of setting the dial arrows to the limit switches for the respective stopping points but thought i'd see if there were any things to be on the lookout for?

Thanks again for the inisghts!
 
When you open it up there are two cams on the main shaft and a locking nut. All you have to do is loosen the locking nut and then adjust the cam stop positions. You can do that while the actuator is mounted on the valve is that’s easiest. Once you get the cams where you want them you just use the switch to test their stop points to see if they line up. You can make all the adjustments right there at the equipment pad. Then just make sure everything is tightened up and sealed. It’s really very simple.
