Hissing La Marzocco

[BarMaidden]

Hi there! I'm a barista up in Bozeman, Montana. Our La Marzocco is hissing something fierce. I thought at first it would be the boiler heating up for the morning, but it has continued for three hours. The weather is extremely erratic here an I was wondering if the cool temperature is messing with the boiler. Or is this is because of a leak or a busted boiler. Thanks!

You turn it off everyday?

No, we don't. However, it gets below freezing here during the night. It was the only thing I could think of that would be happening (aside from the blown gasket theory, which is far scarier).

I would assume there's steam escaping somewhere. Better to have it checked out.
Chances are, it won't heal on it's own.
