Do I need a solid portofilter to use this product?

Hi Steve, I am taking a stab at what is meant by a solid portafilter. You would need a backflush disc for the portafilter to use this product. (Backflush Disc- Basket without holes)
Do you need a closed portofilter to backflush with Caffiza? I have a single shot for a Gazzia RED.

Answer by Sanfam
While Gaggia does not recommend backflushing the classic, the 3-way solenoid it uses allows this to be done. Should you want to backflush the machine, Cafiza is the right product for the job!
