Coffee lovers know that a clean machine is the secret to a perfect cup of coffee. One crucial aspect of maintaining your Nespresso coffee machine is descaling. Descaling is the process of removing mineral buildup from your machine to ensure it continues to function optimally.

Understanding the Need for Descaling

Every time you use your Nespresso machine, minerals in the water, such as calcium and magnesium, accumulate inside the machine. Over time, this buildup can affect the machine’s performance, leading to slower brewing times and even altering the taste of your coffee.

Regular descaling not only ensures that your coffee tastes as it should but also extends the lifespan of your machine, making it a necessary part of coffee machine maintenance.

Identifying When Your Nespresso Machine Needs Descaling

Your Nespresso machine will often show signs when it needs descaling. These signs may include slower brewing times, irregular coffee flow, or even a change in the taste of your coffee.

While these signs can help, it’s recommended to descale your machine every three months as a general rule. However, if you use your machine very frequently or use hard water, you may need to descale more often.

Materials Needed for Descaling

Descaling your Nespresso machine requires a few key materials. You’ll need a descaling solution, which can be purchased from Nespresso or other retailers, and fresh water. When choosing a descaling solution, ensure it’s suitable for under £100 coffee machines.

Always handle descaling solutions with care, as they can be harmful if ingested or if they come into contact with your skin or eyes.

Step-by-Step Guide to Descaling Your Nespresso Machine

Descaling your Nespresso machine is a straightforward process. Here’s a step-by-step guide:

  • Empty the drip tray and the capsule container of your machine.
  • Dissolve the descaling agent in the water tank filled with fresh water and place it back.
  • Place a container capable of holding up to a liter of liquid under the coffee outlet.
  • For most Nespresso models, you can enter the descaling mode by pressing both the espresso and lungo buttons for three seconds. The buttons will start to flash quickly, indicating that descaling mode is activated.
  • Start the descaling process by pressing one of the flashing buttons. The descaling solution will flow through the machine and into the container.
  • Once the water tank is empty, refill it with the used solution and repeat the process.
  • After the second cycle, rinse the water tank thoroughly and fill it with fresh water. Run a brewing cycle with the fresh water to rinse the machine.
  • Exit the descaling mode by pressing both buttons for three seconds.

Troubleshooting Common Issues During Descaling

Sometimes, you may encounter issues during the descaling process. If the machine doesn’t enter descaling mode, try resetting it or consult the user manual. If the descaling solution doesn’t flow through the machine, there may be a blockage. In this case, try the process again or contact Nespresso’s customer service.

Maintaining Your Nespresso Machine Post-Descaling

After descaling your Nespresso machine, regular maintenance can help prevent mineral buildup. Rinse the machine after each use and clean the drip tray and capsule container regularly. Using filtered or bottled water can also reduce the amount of mineral buildup.


Descaling your Nespresso coffee machine is an essential part of ensuring it continues to make delicious coffee and has a long lifespan. By recognizing when your machine needs descaling, understanding the process, and performing regular maintenance, you can keep your machine in top condition.

So, don’t wait until your coffee tastes off or your machine slows down – make descaling a regular part of your coffee routine.
