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!
