with a few minor differences. The first difference is backflushing with espresso machine
cleaner only needs to be done approximately once every 1-2 weeks depending on usage.
To begin, place no more than 1/4 of a teaspoon of espresso machine cleaner into the
backflush disc in the portafilter and then lock the portafilter into the grouphead. Now follow
the same procedure as above until the cleaner is dissolved and the water runs clear (about
5-10 flushes). Remove the portafilter from the group and rinse thoroughly. Then take a
damp cloth and wipe the underside of the group. After you have finished this procedure, I
recommend you pull a shot of espresso and dispose of it to cure the group. You're finished
and ready for another month of espresso.
Setting Pump (Brew) Pressure
To set the pump pressure, install the backflush
disc into your portafilter and then lock it into the
group head.
Activate the brew switch and then wait for the pump
pressure to rise on the gauge.
Use a flat blade screwdriver to adjust the expansion valve screw located to the right
under side of the group head shown in the picture above.
Turn it clockwise to increase the pressure, counter clockwise to decrease.
The recommended setting with the backflush disc is 9.5 - 10bar. When you make
espresso the pressure will be slightly less. If the machine puts out 9.5 - 10 bar of
pressure with the backflush disc, but then when you make coffee the pressure is less
than 8 bar then the machine is fine, it‟s the grind that needs to be adjusted finer.
Setting Pump Pressure On Older Models
The older style machines have a different style expansion valve which involves opening
up the machine. Should you need to adjust the pump pressure on an older style
machine please visit our FAQ section for instructions:
