wassup all. havent posted here in a while. my fx5 keeps making this gurgling sound like there's air in it. i know it shuts itself off to clear the air but the sound comes back shortly after. i even shut the power off and cleared all the air in the canister, but the air comes back and my outlet has lots of air bubbles flowing thru it. just want to post maybe something wrong with my filter if anyone has ever gone thru this already. any input?
