Backflush

Does this work the same way on the Barista Express? A video on how to do that would be awesome!!

Hi; When I start the backflushing process, pressure rises to more than 13 and nothing comes out of portafilter. Once the machine forced portafilter out and it was really scary! I wasn't in the kitchen but It was like bullet when the machine pushed portafilter out. Whats the problem?

Do you also use the dual wall basket when back flushing with the cleaning tablet?

Bi wiggling you risk to damage the plastic slider on which the porta filter sits in the group head.
