We've descaled double boilers, heat exchangers, every superautomatic under the sun and even simple thermoblock-driven machines, but in all of our years giving scale the what-for inside espresso machines, we had not descaled a The first part of the process, of course, was to find a willing participant, and Bunny stepped in to do the job. After working in our retail store for years and performing tune-ups for customers, she knows a thing or two about descaling machines, so we tasked her with researching how to perform it on a manual lever style machine like the La Pavoni. What she learned (and what we then filmed) was deceptively simple! It will take some time, patience, a little elbow grease and, of course, some Dezcal, but it was a very effective method for removing scale within the La Pavoni's boiler and on its heating element. Watch as she guides us through the process. And if you happen to have a La Pavoni or a lever machine that you descale in a different way, we'd love to learn new techniques! Post your process in the comments and we'll share with the class.
