What is the best practice for maintaining the espresso machine?

Regular cleaning and back-flushing are essential practices for maintaining an espresso machine effectively. This process involves running water through the machine’s group head and using a special back-flush detergent to remove coffee oils and residues that accumulate over time. This not only ensures optimal flavor extraction for the espresso but also prolongs the life of the machine.

When machines are not cleaned regularly, these residues can affect the taste of the coffee, leading to bitterness or stale flavors. Moreover, neglecting the cleaning routine can lead to mechanical issues that may require costly repairs or even replacement of components. By prioritizing regular cleaning and back-flushing, baristas can maintain the espresso machine's performance and ensure high-quality coffee extraction for customers consistently.
