Group head purge

Crafting third wave specialty coffee has never been easier than with the Breville Bambino®. However, to experience flavorful, rich, and perfectly extracted espresso daily, proper routine maintenance is necessary. 
To clean your machine just like professional baristas, do a group head purge. This will remove espresso residue and stabilize your water temperature prior to extraction. 
1) To start, select the filter basket you intend to use and place it empty in the portafilter. 
2) Insert and lock the portafilter, then press the '1-Cup' button, allowing the water to run for five seconds. 
3) Press the button again to stop the flow of water, discard the water, and then rinse the glass. Now you're ready to fill your filter basket with the freshly ground espresso of your choice.
