The Nespresso Le Cube is a fully automatic espresso machine that can heat up and pump out an espresso shot in less than five minutes. The Nespresso Le Cube comes preset with two shot sizes: espresso and lungo. While the machine is automatic and requires no lever pulling to brew a shot, you can customize the size of the espresso shot to something other than these two preset sizes. Fortunately, you can reset the machine back to its default setting and erase the custom espresso size.
Turn the machine off by pressing the power button on the top left.
Hold down the “Lungo” button under the brew options.
Turn the machine back but do not release the “Lungo” button.
Release the “Lungo” button once it starts flashing.
