espressso machine question

[bitterbird]

hi guys, i just got a new espresso machine asa gift,
its a breville cafe roma stainless one

everytime i steam some milk when i turn the steam off all steam comes out from the coffee filter area and makes a hissing noise for a second or so.
is this normal

yeah i've had one of those for a while now. i'm sure it's normal, mine works fine (when i can get the damn grind right for it.. but that's another story)

Mine also does it, and I think it's normal. I especially notice it when the machine is truly up to temp.
