Barista Tips – Back Flushing Your Espresso Machine

A Step By Step Guide

Espresso Machine Care

  1. Detach the filter basket from the group handles of your espresso machine, and let them soak in cold water overnight.
  2. Replace the filter basket with a blind back flush disk or rubber blanking disc in the group handle.
  3. Once the blank is fitted, add a heaped tablespoon of espresso machine cleaner to the group handle. Flush out the espresso machine by pressing the button on your espresso machine to let the water run through the machine for no longer than 10 seconds.
  4. Separate the group handle from your espresso machine, and clear it out of any water, cleaner and old coffee grounds.
  5. Repeat steps 3 and 4 a few times, but without the espresso machine cleaner. Be sure that all the espresso machine cleaner that has run through the machine has been cleared out, as if it hasn’t been, the following espressos made by the machine will be tainted with espresso machine cleaner.
  6. Whilst the group handle is detached, gently clean in circular motions the group seal, using only a head cleaning brush.
  7. Reattach the group handle back onto the espresso machine, and flush the machine out with clean water once more.
  8. For machines with more than one group handle, repeat the first seven steps on each other group handle of the espresso machine.

The cleaning of group handles should occur once a week to remove the coffee oils, which can easily be done by soaking them, handle up, overnight in a large bowl of boiling water and espresso machine cleaner.

Ensure that the rubber handles stay out of contact with the boiling water, as this could damage them. Rinse the group handles the following day with fresh water to ensure all cleaner is removed.

These simple steps will ensure that your espresso machine is producing the best tasting coffees and is keeping the machine free from coffee bean and oil build up.
