Sundance '05 Capri - FLO error

[natc]

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 (http://www.hottubworks.com/part-6500-035-item-laing-spa-pump.php). 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.
