I have a spillover spa that slowed to barely a trickle yesterday and my Polaris 360 wouldn't move at all. I took apart the Pentair filter and cleaned all 4 cartridges today and the flow greatly increased but my Polaris still isn't working correctly.
During the summer, the Polaris had good flow, worked great, and the spillover was very active. Now, the Polaris is giving me a lot of problems and the spillover has slowed. Tonight it's about half of what it usually is (and I just cleaned the filter cartridges!).
There is a diverting valve that can direct additional water to the Polaris 360 and if I turn that Jandy valve to send more water to the Polaris the loud whining lessens and the Polaris starts working. But then the spillover is a trickle.
What is going on here? Is my pump dying? Are the cartridges bad?
