Flat_Eric - 👍- that will keep you busy for sure!
If your Pavoni has the teflon sleeve, try the “dry pump” method. You’ll see how fast it heats the group, without having to waste any water. It also helps in removing trapped air and you ending up with a “sponge pull”. I’m not sure if it works with the sleeveless groups, 49mm pre millennium. Anything, just ask away! 👍
Another thing to keep yourself occupied with is coffee roasting. A lot of fun, and sooooo much to take in.
