Regular cleaning with appropriate products is essential to tackle these challenges and keep the machine in optimal working condition.

2. How Espresso Machines Get Dirty

2.1 Coffee Oil and Residue Build-Up

During the brewing process, coffee beans release oils and soluble compounds that contribute to the rich flavor and crema of an espresso. However, these oils can adhere to the surfaces of the machine’s internal components, such as the group head, portafilter, and shower screen. Over time, this residue becomes sticky and can accumulate, affecting the taste of the espresso by adding unwanted bitterness.

If left uncleaned, this build-up can also clog the machine’s internal pathways, reducing water flow and causing uneven extraction. This not only impacts the flavor but can also place strain on the machine’s pump and heating elements.

2.2 Mineral Deposits and Scaling

Mineral scaling is another common issue, especially in areas with hard water. As water is heated within the espresso machine, minerals like calcium and magnesium precipitate out and form scale deposits on the heating elements and internal plumbing. These deposits can lead to reduced water flow, inconsistent water temperature, and even damage to the machine’s boiler.

Descaling tablets or solutions are required to remove these mineral deposits, but regular cleaning tablets can help prevent minor scaling and ensure that the brewing system remains free from other residues.

2.3 Potential Impact on Machine Performance and Taste

When an espresso machine is not properly cleaned, the build-up of residues and scale can have several negative effects:
