It is important to regularly clean your Breville Bambino Plus espresso machine to ensure that it continues to operate at peak performance and to prevent any buildup of oils or residue that can affect the taste of your coffee. Breville recommends cleaning the machine after every use, particularly the 54mm portafilter, steam wand, and drip tray. This involves rinsing these parts with hot water and wiping them down with a clean cloth. It is also recommended that you descale the machine every 2-3 months, depending on the level of usage, to remove any mineral buildup that can occur from using hard water.
