Backflushing
is a vital maintenance procedure you must follow to help keep your machine
running flawlessly for years to come. There are two types of backflushing; one with plain
water, and the other with espresso machine cleaner. The S1 Dream is equipped with a
group cleaning feature to make this a simple process.
Plain water backflushing
should be done at least once a week, however if you are so
inclined, feel free to backflush with plain water as often as you like. It won't harm the
machine and keeps the shower screens clean.
To backflush, you insert the rubber backflush disc into your single portafilter and then lock
the portafilter into the group head. Then enter the menu and cycle through to the
“Group
Cleaning”
section and then press the
OK/Menu
button. The display will prompt you to press
the
Free Flow/Manual
shot button. This will start the backflushing procedure. The pump will
run for 5 seconds and then turn off and will repeat this cycle indefinitely until you press the
Free Flow/Manual
shot button to stop. For a water backflush it is recommended to do this
for 5 cycles and then press the
Free Flow/Manual
shot button to stop the procedure. Then
press the
OK/Menu
button to exit the group cleaning menu.
Backflushing with espresso machine cleaner
is the same procedure as above with a few
minor differences. The first difference is backflushing with espresso machine cleaner only
needs to be done approximately once every 2 weeks or every 35-50 espressos. I don't
recommend backflushing with cleaner more often than once every two weeks unless the
machine gets heavy use.
To begin, place 1/4 of a teaspoon of espresso machine cleaner into the backflush disc 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 and rinse thoroughly. After rinsing then perform a plain water backflush for
another 5 cycles to remove the cleaner residue. 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 and then you’re finished.
