Sundance '05 Capri - FLO error

Hi, I have a '05 Sundance Capri that has just started to display the FLO message. Per info on the boards, I replaced the filter and the pressure switch. I still get the same message.

I don't know what to troubleshoot next, and I'd rather not call a repair person just yet.

I saw some postings about the circulation pump maybe causing the message. How do I inspect/troubleshoot to determine if this is the issue? Pumps appear to be working normally.

Any suggestions would be great!

Thanks!

Yes you would want to check your circulation pump. It should be a small little pump that runs 24 hours a day. It should have 3/4" plumbing lines running to it. If that is running you should see a small stream of water flowing out of the return fitting in the spa. If that pump has stopped operating you will get a FLO error code. This pump is not the same as the large therapy pump that comes on when you push the jets button.
