Cleaning Brewing Components
Clea
ning the brew head on the lever
-
style machines is necessary for optimal
flavor
a
nd
brewing pleasure. Three different processes
are
involved with cleaning the brew head
:
backflush
ing
with water only, backflush
ing
with cleaner and removing the showe
r screen
for cleaning by hand.
Under normal household conditions
,
we recommend t
hat you
backflush your machine with
water about ever
y
10 to 14 days.
You shoul
d backflush with
cleaner about
12
times a year. It is also recommended that you remove the shower s
creen,
inspect and clean it as well as
the brew group behind the shower screen a
s often
as
necessary. When you remove the brew group
for inspection
,
you will be a
ble to judge
how often you
want to clean it by how dirty it is.
To prepare for a backflush cycle, your machine must be up to brew temperature and
pressure.
Backflushing wi
th
Water Only
:
1.
Place
the single
-
shot filter baske
t into the portafilter and insert
the rubb
er
backflush disc into the
filter basket with the nipple side facing up or use
a
stainless steel blind filter basket.
2.
Raise the control l
ever for 5
-
10 secon
ds or until the pressure builds up. Then
,
move the lever to the down position to release the pressure.
3.
You will notice
a
pressurized stream of water released into the drip tray a moment
after you turn the lever to the
DOWN
position. This is the backpr
essure release, or
the backflush. Check the water in the drip tray. Is it dirty? If so, then repeat the
process until the released water is clean.
Backflush w
ith Cleaner:
You
should
backflush with a detergent
12
times a year
. We recommend using Urnex
Caf
iza
, which delivers excellent results
. Add 1 tablespoon of the espresso machine
cleaner to the blind filer basket/backflush disc an
d follow the procedure above.
It may
take 5 cycles or more to completely clean the machine. Rinse the brew group thoroughly
a
nd backflush 4 times without cleaner to make sure that there is no cleaner left.
