Roger help with new 9015

[Billy Rocket]

Got a 9015 a few months ago and I LOVE IT!!!
However, in the last few days, it has started to growl. It sounds like it is clearing its throat? The sound lasts for less than a second. It makes the sound once every minute or two. It is still working GREAT.

Any idea what it is and how to fix it?

Thanks in advance for your help.

Bill

It could have two causes, the pump or the air system. If it is coffee maker kind of noise it is from water entering the air intake and it is probably just submerged too deep. If the noise is a growling from the pump, it is likely that a part has a bad fit/ came loose. The usual cause is the bush bearing which is a collar under the impeller, around the hole the magnet sits in. This often slides out a bit in shipping and just needs to be pushed in all the way.
