I got a Quick Mill Andreja Premium about a month and a half ago. Nice machine and I'm enjoying the coffee it makes a lot.

One thing that concerns me however is the sound it makes. My machine basically sounds exactly like the one in this link:



The comments to the video mostly say what I'm thinking - that the sound is from the OPV and that the brew pressure might be too high. My brew pressure is set a bit high (about 10.2 bar - factory setting) but the coffee is fine nonetheless.

Now, you lot are a much more knowledgeable resource than YouTube . So what do you say - is this merely the OPV? And would lowering the brew pressure help at all?

Thanks,
C

Claus, I merged your topic with a thread on the same subject.

Yes and probably. For more details, see the posts above.

Thanks Dan.

Did a quick search before posting but didn't find this post. I guess one man's screech is another man's squeal
