How to clean the shower screen

Enjoy café-quality third wave specialty coffee at home with the Oracle®. To ensure that every Americano you create tastes its best, you’ll need to properly clean and maintain your machine. 
One essential step is to periodically rinse your shower screen. To clean it, we recommend running hot water through the group head with the filter basket and portafilter in place, but without ground coffee. This hot water rinse removes loose grounds and any coffee oil residue. 
Keeping the shower screen clean like this helps to ensure each extraction is perfect, with nothing coming between you and the delicious flavors of espresso. 
With the Oracle®, making coffee drinks like a professional barista has never been easier.
