Backflushing: How do I backflush using espresso cleaner?


  • Start 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.
  • Once 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.
