How to Backflush an Espresso Machine

Back-flushing is an important part of cleaning the espresso machine.

Back-flushing an espresso machine is an important part of cleaning the machine at the end of the day. If you allow oils, coffee grinds and coffee splatter to accumulate, you can actually alter the flavor of the espresso. This in turn lowers the quality of the espresso you are making. Any particles that build up will also interfere with the extraction process. Back-flushing the machine is an important part of cleaning that ensures your espresso is made properly each and every time.

Things You'll Need

• Blind Filter
• Espresso machine cleaning solution

Instructions

1. Place a blind filter into the group handle of the espresso machine. Normal filters will have an opening so the water and espresso can pour out. A blind filter does not have an opening.

2. Add one teaspoon of espresso machine cleaner into the blind filter. Secure the group handle into place on the group head.

3. Press the brew button or the manual override. The button to use will depend on your machine. Press and hold down the button for three seconds and then release. This causes the water to flow int o the group handle. The blind filter forces the water back into the machine, creating a back-flush.

4. Repeat holding down the button and back-flushing the machine eight times.

5. Take off the group handle. Remove and rinse the blind filter that was placed in the group handle. Proceed with cleaning the espresso machine.
