Got a hand-me-down machine in December. From use #1 I was able to create a solid foam using the methods commonly linked to on here (youtube videos).
About a month ago, things started going badly. All of a sudden, the milk simply won't foam. I haven't changed anything. Instead of foaming, it is boiling. In my small pitcher, it is violently bubbling and splashing liquid out of the top (a few burns result). Milk is the same, container is the same, method is the same.
I've tweaked around with more or less milk. I've removed the steam wand and completely cleaned it. I'm at a loss at this point and can't even find someone with the same problem.
My setup isn't great. Hell, it's probably not even considered good. But, I was doing totally fine for 3 months and now I can't seem to figure this out. Some help in what to do would be great appreciated. I have a gut feeling it's going to be "buy a good machine" which is fine with me. Since I got this one free from the folks.
