iaqualink trouble shooting help

[RodB]

Hello automation members! I'll do my best to explain whats happening. I'm a novice at best with electricity just enough to keep from getting shocked. Opened this year equipment is 3 years old. All Jandy equipment. My JVAs connected to my subpanel are not working properly all seem to have the same issue however when I opened one of them it did smell as if it was burnt but can't be sure on that. First thing I found was the fuse in the subpanel was blown I replace it and began pulling the connection to each JVA and I did find that the smelly JVA did blow the fuse how ever when I replace it and left that connection diconnected the other JVAs still did not fuction. Thats a bit confusing because if the one blew the fuse why would the others not work? Theres only three JVA hooked to the subpanel. I've included photos for more deatil and maybe help with my issue. I have three pumps filter, and two for the spa, the spa bumps have dual purposes thats where the JVAs come into play I have a slide, a shallow fountain and two deep end fountains. The three JVA on the subpanel direct the water to the features using the app. Everything worked when I closed last year. Any help would be greatly appriciated! The photos provide the main and subpanels.

Turn off power to Aqualink
Ensure fuse is good.
Then unplug all 3 JVA’s from the socket on the board.
Then plug in 1 JVA to the INTAKE socket. Turn on power and boot up.
There is a switch on the JVA that goes from ON to OFF to ON. When moving from ON to ON the JVA should rotate if it has power.
If it does, then you know this socket and JVA is good.
Then plug that same JVA into the RETURN socket, Check if it moves when going from ON to ON again.
If so then that socket is good. Continue to check all sockets with a know JVA that works.
Then move on to checking each JVA into a known socket that works.
Basically, trying to figure out if the socket or the JVA is bad - or both.

Thanks for the reply even on a holiday! The JVAs are in the sub panel all others are in the main panel. Explain what you mean by intake and return sockets

Ok. I have not used a subpanel but thought the sockets may be marked same as on main panel. The 4 sockets are normally marked Intake, Return, JVA 3 and JVA 4. However on the subpanel board I now see they are named JVA 3, 4 , 5, 6. . Hard to see in your photo.
So try to determine if one JVA and on Socket work.
Do other items on the Subpanel work? Want to rule out that there is not an overall outage on the subpanel before we just look at the JVA sockets.

I only have those three JVAs on the sub panel. I'll try #4 to see if its good. when I had a good fuse in the sub panel and selected the feature i.e. 1, 2, or 3 it seemed to have power because when I manually switched the JVA I could feel it trying to move but it seemed to not have enough power "I'm only speculating on that" Also when I only put the middle plug in the socket #2 and powered the subpanel the fuse blew. I'm confused if that JVA is bad why would it affect the operation of the other two? I'll try what you said using #4 which is not currently being used.

Is that all the subpanel powers? No pump? No lights? Anything that you could try to determine that the whole subpanel is getting power?

The sub gets power until the fuse blows

Thanks - another idea - are all your JVA sockets on the main AquaLink panel used?
If not or if you can disconnect those and put in these JVAs to test. The goal is to try to find if the JVA is bad or is the board in the subpanel bad.
Have you priced a new board for the subpanel?

You also indicated one JVA was smelly. Have you purchased a new one to replace it?

Which picture is the subpanel showing the JVAs plugged in?

Show us where the subpanel connects to the main panel.

It is #3931 and 3932

I have not purchased a new JVA I’ve been shopping around they’re very expensive trying to find the best deal. Thanks
