Before we delve into the importance of descaling, let’s take a closer look at how a coffee machine works. Understanding the inner workings of your machine can help you appreciate why descaling is essential for its proper functioning.

A typical coffee machine consists of several key components that work together to brew your favorite cup of java. These include:

• Water reservoir: This is where you fill the machine with water. The water is then heated and used in the brewing process.
• Heating element: Responsible for heating the water to the optimal brewing temperature.
• Pump: Draws water from the reservoir and pushes it through the system.
• Portafilter: The part of the machine that holds the coffee grounds. Water passes through the grounds, extracting the flavors and oils.
• Filter: Ensures that only the brewed coffee passes through while trapping the coffee grounds.

When you turn on your coffee machine and initiate the brewing process, here is what happens:

1. The heating element heats up the water in the reservoir to the ideal temperature, usually around 195-205°F (90-96°C).
2. The pump draws the heated water from the reservoir and forces it through the system.
3. The water passes through the coffee grounds in the portafilter, extracting the flavors and oils through a process called infusion.
4. The brewed coffee then flows through the filter, leaving the coffee grounds behind.
5. Finally, the brewed coffee is dispensed into your waiting cup.

This entire process happens within a matter of minutes, providing you with a freshly brewed cup of coffee. However, during this process, the water comes into contact with minerals present in the water, such as calcium and limescale.

Over time, these minerals can accumulate and form deposits inside the machine. These deposits can interfere with the smooth flow of water, disrupt the temperature control, and affect the extraction process. The result is a compromised brewing performance and a less-than-optimal cup of coffee.
