If you just cleaned it, then you may of freed some debris and is caught in the impeller. Can you take it offline, clean out the impeller section? Did you lube it? You may be able to find a diagram Online to take it apart and lube if necessary, goggle it!

my ampmaster is getting less noisy ...what are my chances that debris in impeller can just eliminate itself?

I would clean it out of before you damage the impeller which could be worse then leaving it alone and cleaning it's self out.

I do not have a check valve on the return so I get a little backwash. Last week my pump was spitting air bubbles and clicking. Power off and out comes a section of macro. I would vote debris.

Dolphin Ampmasters will usually clean themselves out with a few power cycles. Just unplug it and restart a few times. If this doesnt work then tear it down.

I found the same as what Don says. Best if possible when you shut it down to not have any check-valve preventing the water return. Sort of wash/backwash/wash/backwash. Like working a car out of a rut. The pebble in there can get knocked loose and blasted out.

Did the pump clear itself?

It got much quieter but never back to perfectly silent

Hello nata, is the sound scraping or whining?

 

[Scooterman]

Maybe time to take it apart clean it & lube If necessary, these aren't that hard to do!
