ADJUSTING PUMP
BREW PRESSURE
STEP 01
The Vetrano 2B Evo has a dual manometer (12/13). There is one gauge that
displays the brew and steam boiler pressure. We will be referring to the bottom
needle (13) for your brew pressure. For an accurate reading, insert the backflush
disk in place of the insert basket into the portafilter. Always check pump pressure
with the backflush disk in place of the insert basket prior to making any adjustments.
STEP 02
Remove the rubber grommet/plug on the right-hand side
of your Vetrano 2B Evo. This will expose the rotary pump's
adjustment screw, as shown.
STEP 03
Raise the brew/cam lever (11). If the desired pressure is not reached in a couple of
seconds with the brew/cam lever (11) raised and the backflush disk in place of the
insert basket within the portafilter (10) adjust accordingly.
REDUCE BREW PRESSURE
Turn the pump's adjustment screw clockwise to decrease the brew pressure.
INCREASE BREW PRESSURE
Turn the pump's adjustment screw counter-clockwise to increase the brew pressure.
STEP 06
Once the desired pressure is reached and determined with the backflush disk
installed in place of the insert basket in your portafilter.
After adjusting the pressure on your machine, you may notice that an adjustment on your grinder will also be required.
