by inserting your blank (blind) basket into the portafilter, and then
add no more than 1/2 teaspoon of approved espresso machine cleaner into
the blank. Secure the portafilter firmly into the group and activate the pump; let it run for approximately 10 seconds.
- Turn the pump off and wait 10 seconds to give the detergent time to dissolve the coffee oils.
- Repeat the previous two steps 4 to 5 more times; you may need to repeat these steps even more if you used too much detergent.
it appears that all the detergent is dissolved, remove the portafilter
and run more water through the group. Continue to do so until all the
detergent is gone.
- Moisten a soft cloth
towel, then push it up in the gasket groove and trace the full inner
circumference to do an even more thorough cleaning.
- Once you finish, pull a shot and throw it away. This tossed shot ""cures"" the group by coating it with oils. Note! There are just as many machines that have problems as a result of improper or too frequent backflushing as those with problems because they were not backflushed at all.
