We have a 2004 Victory Series 1500 Cal Spa which was filled yesterday in preparation for use this fall. After a few hours of being fille I could hear it out my window turning on and off, so i went outside to see what was wrong. The pump is circulating on and off at about a 2 second interval, as well as the light. I took a quick glance through the manual but didnt notice anything on this situation. Anyone have any ideas?
