Recognizing this discussion spans many years... I have an original X1 bought in 2001 with the aluminum boiler. After many hours spent trying to extract 3 of the 4 screws that broke when we tried to remove them so that I could lean the boiler, I have tried every tool and YouTube video, and, it's not looking good. I was finally able to drill through one, I inserted the drill bit for threading to try and expand the hole size to the original, and the bit instantly broke, wedged into the hole I created. Now I can't drill through that bit because of what its made out of... I love my X1. I don't want a new coffee machine. I now have the other replacement parts it needs, but am stuck on the boiler. Also, I live in CA. If anyone has an aluminum boiler they are willing to ship to CA, you will be my hero. Thanks! Suzan
