We have a 2007 Sundance Marin that still runs awesome for its age. Currently I've come across a small issue where I get a FLO message when filter is fully connected. If I loosen one side its fine. I've replaced the switch about 5 years ago, circ pump about 3 years ago, and change the filter every 6 mos. I'm wondering if I should d/c the line to the circ pump and check for debris.
Any suggestions?
