Coffee plays an important role in many people’s daily lives, providing an energy boost and a comforting ritual to start the day.

Nespresso Citiz is a popular coffee machine that offers convenience and high-quality coffee, making it a beloved appliance in many households.

To ensure the longevity and optimal performance of the Nespresso Citiz, regular maintenance is necessary, and descaling is an effective solution to remove mineral buildup and improve the machine’s functionality.

Understanding Descaling

The Role of Water in brewing coffee

Water is crucial in brewing coffee as it is the primary ingredient in any cup of coffee.

The water quality affects the taste, aroma, and flavor of the coffee.

It is essential to use clean and pure water for the best coffee experience.

The minerals in water and how they affect the machine

Water contains minerals like calcium and magnesium that can build up in the machine over time, causing blockages and damaging the internal components.

This build-up can also affect the taste of the coffee by altering the water temperature, flow rate, and pressure.

What is descaling?

Descaling is the process of removing mineral buildup, or scale, from the internal components of the coffee machine.

Descaling is an essential maintenance task that should be performed regularly to keep the machine functioning correctly and ensure the coffee tastes great.

It involves using a descaling solution or a mixture of vinegar and water to dissolve and remove the mineral buildup from the machine’s internal components.

How Often to Descale Your Nespresso Citiz

Recommended frequency

Nespresso recommends descaling your Citiz machine at least once every six months to ensure optimal performance and maintain the quality of your coffee.

However, the frequency may vary depending on the water hardness in your area and the frequency of machine usage.

Here is a table that should give you a better idea on how often to descale your Nespresso Citiz machine:

UsageDescaling Frequency
Home use, soft water (<10°dH)Every 3-6 months
Home use, hard water (>10°dH)Every 1-3 months
Office use, soft water (<10°dH)Every 3 months
Office use, hard water (>10°dH)Every month

Importance of descaling for machine maintenance

Descaling your Nespresso Citiz helps to remove mineral build-up in the machine’s internal system.

Over time, mineral deposits can clog the machine’s pipes, affecting water flow and pressure.

Descaling also helps to maintain the temperature stability of the machine, which is crucial for brewing quality coffee.

The consequences of neglecting descaling

Neglecting descaling can lead to various problems, including a reduction in the quality of your coffee, slower brewing time, and even damage to the machine.

Over time, the mineral build-up can cause the machine to overheat, resulting in permanent damage that may require costly repairs or even replacement of the machine.

Therefore, it is crucial to descale your Nespresso Citiz regularly to avoid these consequences.

Tools Needed for Descaling Nespresso Citiz

Descaling your Nespresso Citiz requires a few basic tools:

  • Urnex Dezcal Activated Scale Remover Kit: This is a descaling solution that is specifically designed for use with Nespresso machines. It comes with packets of citric acid that dissolve mineral buildup in the machine.
  • Water: You will need to use water to mix the descaling solution and rinse the machine after descaling.
  • Large container: You will need a large container to hold enough water to fill the water tank of your Nespresso Citiz. This container should be able to hold at least 1 liter of water.

Steps to Descaling Nespresso Citiz

Before starting the descaling process, make sure to gather all the necessary tools and ingredients.

Follow these steps to descale your Nespresso Citiz:

Getting Your Citiz Ready

  1. Ensure that no capsule is loaded in the machine.
  2. Remove the empty capsule container and drip tray from the machine.
  3. Place a container that can hold at least 1 liter of water under the dispenser spout.
  4. Fill the water tank with 500ml of water and add the descaling solution to the tank.
  5. Turn on the machine by pressing any button.

Starting the Descaling Process

  1. Activate the descaling mode on your machine by pressing both buttons at the same time and holding them for three seconds. The two buttons will start flashing to indicate that the machine is in descaling mode.
  2. Wait until the two buttons stop flashing.
  3. Press both buttons again for three seconds to start the descaling process.
  4. Press the Lungo button to begin the descaling process.
  5. Allow the water to drain, flow through the machine, and dispense into the container. The descaling solution will remove any build-up of limescale and mineral deposits in the machine.
  6. Repeat the process with the used solution in the water tank to ensure that the machine is thoroughly descaled.

Rinsing Your Nespresso Machine

  1. Empty the water tank and rinse it thoroughly.
  2. Refill the tank with fresh water.
  3. Restart the cycle for a third time by following the same steps as in the previous section.
  4. Empty the tank and dispose of the water.

Exiting Descaling Mode

  1. Press the two front buttons simultaneously for three seconds to exit the descaling mode.
  2. Confirm that the descaling mode is off by checking that the two buttons are no longer flashing.

By following these steps, you can maintain the performance of your Nespresso Citiz and ensure that your coffee continues to taste great.

Nespresso Citiz Key Features

If you’re not already familiar with the Nespresso Citiz, it’s a pretty cool machine with a lot of great features! Here are some of the highlights:

Compact design: The Citiz is designed to be space-saving, so it’s great for small kitchens or offices.

Pre-programmed buttons for espresso and lungo drinks: If you’re in a hurry and don’t have time to customize your drink, just press one of these buttons and the Citiz will do the rest.

Customizable buttons: On the other hand, if you like to customize your coffee, you can set the Citiz to dispense exactly the amount of water you want for your drink.

19 bars of pressure: This is what gives your coffee that rich, smooth crema on top.

Quick heating time: The Citiz heats up in just 25 seconds, so you don’t have to wait long to get your coffee fix.

Milk Frother Add-On

The Aero 3 Milk Frother is an add-on device for Nespresso Citiz that allows users to create frothy milk for their coffee drinks.

Using a frother can enhance the flavor and texture of coffee drinks, particularly those that call for milk or milk-based ingredients.

Descaling the Nespresso Citiz does not require including the Aero 3 Milk Frother in the process, but it is recommended to clean it separately to ensure optimal performance.

Why Should You Go Organic?

Some people may doubt the effectiveness of using an organic descaler for their coffee machine because it’s made from natural ingredients.

However, organic descalers are just as effective as other descaling solutions, while also being much better for the environment.

They are non-toxic, biodegradable, and won’t harm the ecosystem.

Additionally, choosing organic coffee products can further reduce your environmental impact.

Many coffee brands offer organic options that are grown without harmful pesticides and chemicals, helping to preserve the soil and promote biodiversity.

By choosing these products, you can enjoy great-tasting coffee while also doing your part to protect the planet.

How To Clean Your Nespresso Citiz

It’s easy to forget to rinse your Nespresso machine after every use, but it’s important to make it a habit.

Over time, coffee sediment can build up in the spout of the machine, and it could even block the whole system.

To clean the coffee buildup inside the spout, you can use a straightened paper clip, pipe cleaner, or q-tip to scrape around inside the spout.

Once you’re done, close the lever and rinse through a couple of times to wash out any particles that have become dislodged.

It’s not just the spout that can get clogged up – coffee grinds can also accumulate against the spikey pyramids inside the capsule mechanism that are used to pop open the foil lid of the coffee capsules.

This can result in a blocked or restricted flow of water, making it difficult for it to pass through the pods.

To prevent this from happening, we suggest using an old toothbrush to scrub the inside of the capsule mechanism clean from time to time.

Once you’re done, close the lever and rinse through a couple of times to wash out any particles that have become dislodged.

Keeping your Nespresso machine clean can ensure that you get the best possible coffee experience every time.


Descaling is an essential step in maintaining the longevity of your Nespresso Citiz machine and ensuring a quality coffee experience.

Thankfully, the Nespresso Citiz has a user-friendly descaling process that can easily be incorporated into your regular maintenance routine.

We encourage all readers to make descaling a regular habit to keep their Nespresso Citiz in top condition for the best coffee experience possible. Happy brewing!
