Another newbie question re: rebuilding a La Pavoni Millennium. I've descaled w/ Cafiza, replaced all the seals, lubed it up and put it back together.
It heats up fine, the steam wand releases a ton of pressure, doesn't appear to be leaking anywhere. All good. However, when I lift up the lever and try to do any sort of pumps, no water, nor any pressure that I can discern, builds and passes through the shower screen. Something seems to be blocking the
water. I've checked the metal group tube, and it is clear, and the screen itself is clear. When looking into the group, is it supposed to look like this (pic attached) w/ that plastic cylinder as placed? Thanks.
