When I press the middle button to brew espresso, hot water shoots out of the frothing wand instead of the espresso brewer. I don't see any sort of obstruction in either one, but I can't get the machine to do anything else.
I'm a college student, so it hasn't been used in a few weeks.
I don't understand how it worked fine before and doesn't now. Please help!
