David, The pod kit for the Rancilio Silvia only works in the newest version (the "V2"). If your machine has a drip grid that has the same size holes over the entire surface of it, you have the version that can not use the new pod kit. The V2 has a different pattern on the drip grid. On the steam wand side there is a curved pattern of holes. on the brew side is a circle of slits.
