A blind filter basket is an important tool for cleaning and maintaining your espresso machine. It's a small basket that fits into the portafilter and is used to backflush the machine - that is, to clean the grouphead and internal parts of the machine.

To use a blind filter basket, you'll need to add a cleaning agent, such as a specialized espresso machine detergent, to the basket. Then, you'll lock the portafilter into the grouphead and activate the backflush function on your machine. This forces the cleaning agent through the machine's internal components, removing any buildup or residue.

The blind filter basket is called "blind" because it doesn't have any holes in the bottom, which allows the cleaning agent to build up pressure and flow back through the machine's internal components more effectively. 

Using this type of filter basket is an important part of regular espresso machine maintenance. It helps to remove any buildup or residue from the grouphead and internal components, ensuring that your machine is running smoothly and delivering consistent and delicious espresso shots. It's recommended to backflush your machine with a blind filter basket at least once a week for optimal performance.

I can't express enough how a blind filter basket is an essential tool for cleaning and maintaining your espresso machine. By using it regularly, you can ensure that it's running smoothly and delivering the best possible espresso shots. So, add a blind filter basket to your espresso machine maintenance routine today and keep your machine in top shape!
