Weird noise coming from Grundfos macerator

[hsadat]

Hey guys, hope you're all good

My macerator is making a strange noise which is hard describe so below is a link to a video to make it easier to understand the noise. You can hear the noise at around 10 seconds! I've checked inside the tank and assessed the motor and everything seems clear. The unit still operates as normal with the addition of the noise.


Should I be worried ? I am still under guarantee so I can replace the unit if the noise is a indicator of a failing unit.

@rpm I'm sure you might have an idea

Thanks

Never mind, I fixed the problem. Tightened the screw for the blade and the noise disappeared.

I was going to suggest removing the spokey dokey’s
