Cuprajake ah that’s really interesting, thanks Jake. I’ve never used a lever or an E61-based machine, so it’s good to know about their different cleaning requirements. I think I’m lucky with the DE1 as it has a separate water path for clean and dirty water. They’ve also just changed the upper and lower brass parts of the group head from brass to PPS, which aside from being less of a heat sink and thereby making temperature profiling more accurate, is also easier to keep clean.
