Without a pressure release, they might explode right? Seems bad, I would expect it to be standard equipment.

- menaerus 4y agoThey are not going to explode but on such machines if you remove the portafilter straight after extracting the espresso, the puck will "explode" and is going to create a mess. In more expensive machines this is regulated through OPV and solenoid valve through which the pressure built up is going to be released.
