Hi all,
I have Portofino Del-1 that I am learning how to operate. I have read that these machines have an electronic pre-infusion cycle but I have no idea what that means other than pre-infusion leads to better espresso. Does anyone know how the pre-infusion cycle works on these machines and if and how it is programmable? Also I have been looking for parts diagrams, operating, and service manuals but they seem to be hard to come by. I would appreciate any and all advice concerning this machine. . . Thanks so much.
Ben
