Hi. My name is Jim Piccinich with 1st-Line Equipment
and we’ll be going over on how to backflush an espresso machine. But, before we do that, there’s a reason why
you want to backflush an espresso machine that is capable of backflushing – it’s because
folks leave their coffee in the portafilter. The oils from the coffee end up in the dispersion
screen. Basically, what happens is it gets very bitter
coffee and espresso out of the machine, so you don’t want to leave the ground coffee
in the portafilter.
