did you do anything to it in the first place to make it stop???? did you clean it before it stopped??
NO, turned it off and removed the skim cup. I put the cup back on plugged it in, had to blow through the half inch tube on the pump intake to jump start and waa laa - big bubbles - no foam. I have since taken it apart again. Everything looks fine, needlewheel is in center on the ceramic shaft. Ron when you plug your's in does it fill the skimmer and start up on it's own, or do you have to get it going like I do? I'm guessing yours just fills and goes when you plug it in. I think my pump is defective.
