I've lost my steaming mojo
I'm not sure what's happened. I was getting great microfoam on my old Oscar since forever, but after going away for a fortnight, I came back and the milk stays thin. I did some descaling and steam pressure looks all right (not that I can tell for sure), but I'm still having trouble finding the zone between normal milk and useless big bubbles. Might it be a pressurestat or other mechanical problem? Or is it just me?
Hi Mate, Is this happening with all brands of milk your using?
It's funny you mention this because I've been having the exact same problem, though with a different machine.
I have 2x EM6910's one at home and one at work. I get perfect foam at home but at work lately I've been getting a horrible mix of watery milk and giant bubbles that haven't incorporated.
Both using the same milk though my machine at home uses a big jug and milk quantity.
I was having an issue at home as well but discovered I was just trying to make my milk too hot (I think my temp gauge is inaccurate) and by stopping 5 degrees earlier it made all the difference.
I did my milk at work this morning and it came out much better (though still not as good as home). I have been putting more milk in the jug and I tried steaming into the back corner to create less swirling. It helped.
It could depend on the brand, or sometimes it can be a seasonal thing, something with the enzymes in the milk. Sounds crazy but it's true!
In with the daft but (imho) obvious question... have you checked your steam tip and tube to makes sure they're not clogged up?
I was about to post a thread asking if anyone else has problems with the tips crudding up a lot.. in extreme cases i've seen you're symptoms due to insufficient pressure to form the micro foam.
