We have a 2001 Sundance Altamar. I replaced the circ pump again yesterday, it was not running and I had the FLO message. The only time the pump runs is when it is heating. I have the owners manual and I followed the instructions to change the program to run 24 hours, but it does not change anything. The other programing is in the standard mode and the panel in not locked. We have had this tub since new and the circ pump running has always seemed like it has a mind of it's own. This is the first time I have tried to program the circ pump. Am I missing something? Thanks
