I've had a issue latley with my whisper HOB making grinding sounds. I thought it was the impeller so I drained the hob and cleaned the impeller and the well it sits in. I am still getting the noise and the motor is warm (not hot). Thinking it was the intake sucking up the occasional air pocket from my bubbler I turned off the bubbler...still grinding away. anyone have any suggestions on this?
I would first suggest once again removing the impeller and checking it for dents, bent areas, or other damage. Typically the whisper filters rattle as you described when the impeller magnet has been damaged or the shaft has been bent. You might want to try ordering a new impeller for it. If your lfs doesn't stock the part you can contact the company to find somewhere that does.
Well the impeller is pristine. straight as an arrow and no damage. I thought the little retaining rinng in the intake tube might be the culprit. Im gonna check that tonight when I do my weekly PWC. Im gonna lube the impeller seat with some petroleum jelly and see what happens.
