Probably your pressurestat has stuck and is sending power to the steam boiler when it shouldn’t. The hissing is the over pressure relief on top of the boiler, preventing you from having a bomb on your countertop.
There are lots of previous threads on this, and you can bypass it or reverse it temporarily to get coffee today (ie power to brew boiler directly), but do NOT leave it in this configuration. Sometimes tapping on the p-stat will let it come unstuck also, but you’ll still need to replace it. Lastly, you can disconnect the lead that goes to the steam boiler if you don’t use steam for your morning shot, until you get the new p-stat installed.
