Hello

A few months ago I bought an old Brasilia Mini Classic from 2006. Both a machine that has been well taken care of and one that had been on a shelf for a good amount of years.
It's been running smoothly but yesterday when brewing it started making a loud noise. When I first pull the lever I get the nice buzzing sound from the pump but as soon as pressure is created it get really loud.
Pressure reaches 12bars and the needle vibrates but it's been like this the whole time and since I make steady brews without any problems I have not paid attention to this.

I am posting two videos. One of the noise and one where you can see the needle at 12bars. I'm adding links to PCloud which is the cloud storage I use. I didn't know how else to post videos here.

Any help and guidance will be highly appreciated.

I'd take the cover off and see if something is touching when it reaches full pressure. I don't think it's sounds wrong, but I did here something that sounds like the pump is hitting the case, It should be isolated on rubber mounts.

Thank you. I'll do that and see if that works. Thanks for getting back to me

Agree...nothing too egregious. Sounded like my old Andreja. Over years of usage, perhaps the rubber (used to isolate the pump) is gaining flexibility/degrading. Perhaps you should replace those mounts/brackets.
