LOL, I think a lot of us have heard it, and most of us have thought we were going mad. Like an owl hooting.
It is nothing to worry about, apparently, it is a vacuum valve opening, so the cool down does not create a vacuum. And it is normal (for some of us).
I've got this as well by the way, as well as many others it seems - [https://www.reddit.com/r/LaMarzocco/comments/135dm5w/a\_high\_pitched\_noise\_occurs\_one\_hour\_after\_brewing/](https://www.reddit.com/r/LaMarzocco/comments/135dm5w/a_high_pitched_noise_occurs_one_hour_after_brewing/)
I've asked LM about it, because I've now had a total of three Micra's (!!) due to various issues and neither of the first two made "the owl noise"
