Title
How to Descale the BES900/BES900XL Breville Dual Boiler
Introduction
I decided to write this simple guide as I had a hard time finding a comprehensive description for how to descale the BDB 900 in one place. It's really quite easy, but it takes a little extra patience and time to do it safely.
As you may know, the BES900/XL wasn't designed to be descaled easily. The boilers do not have drains, and due to the electrical current carrying capability of descaling solution, the boilers may think they are full when they are not, and can trip the thermal fuse if they heat up while mostly empty. As long as we take this into account, we can descale safely with just a few simple supplies and tools.
