After two weeks, the steamer setting was making a loud, and I mean A LOUD, screeching sound while steaming

Another common issue is that the machine will make a loud "buzzing" sound and/or leak water out of the bottom of the machine

and then it started making a horrible mechanical grinding sound when the water would flow

The machine makes all the right sounds as an industrial/commercial machine which I am used to

Now it makes a horrible screeching sound when the pump first starts

Third, the sound is really loud

The weekly cleaning sound intensive but really takes maybe 5 minutes

The steam arm is easy to use (as noted by others, it pulses and the output is loud sounding in the milk frother at

Do not get any moisture in the bean grinder, it will jam up and make an annoying clicking sound, forcing you to dis-assemble the grinder with beans still in it, usually making a mess

Even after descaling, the fog was still present and the sound was incredibly louder than when I first purchased the machine

To be exact, after 6 months it started making a terrible buzzing sound

Both had the same issue, the pump seems to stop working correctly and emits a loud buzzing sound.
