Goldline Aqua Logic AQL-PS-8. Defective Relay?

[CC57]

I can NOT turn off the filter pump from the panel. I have to throw the breaker for the pump to stop.
Other options, such as turning the cleaner or water feature on to off and back, function properly.

I pulled the panel cover off. Took some measurements with my VOM. The main board seems to be controlling the voltage going into the relay correctly: filter to On, 24v present. filter to Off, 0 volts. So I'm thinking the relay is defective.

Would y'all agree, defective relay?

And I have a couple of other relays positions that are not in use. I was thinking of swapping relays around, see if that clears the problem. Anyone know if all of the relays on the panel are the same?

Thanks all

They are all the same.

How to determine the model number of my Jandy Power controller

I am trying to diagnose a problem. My pool filter pump is continuously running. I suspect the relay might need replacing. In order to find the compatible relay, i need to determine the part number of my jandy controller, see picture attached. I have a pool, spa , light, blower and propane heater...

JamesW, thank you very much for all the info.
Do you suspect my issue is a bad relay?
So I just watched the video you included, which gives me something else in the relay to check. Thanks

Did a little percussion maintenance on the defective relay. It started working again and did for a few days while I waited on the delivery of the new replacement relay.

Even though the old one seemed to be working fine now, never know when it might start failing again.

So I installed the new one but kept the old one as a just in case next time spare.

Thanks again JamesW

When the new relay comes in remove the tan part to inspect the contacts by prying at the arrows.

Most likely, the contacts are burned from arcing.
