What Is Descaling and Why Does It Matter?
Descaling is the removal of limescale from the internal components of a coffee machine. Limescale forms when water containing calcium and magnesium is heated. These minerals do not evaporate with the water; instead, they crystallize on surfaces such as the heating element, pump, and tubing. Over time, this layer thickens and restricts water flow.
For the Nespresso Citiz, limescale buildup can cause several problems. It may reduce the temperature of the water reaching your capsule, resulting in under-extracted espresso that tastes sour or weak. It can also reduce pressure, leading to slower flow or incomplete brewing. In severe cases, heavy buildup can damage the pump or heating element, resulting in costly repairs.
Descaling works by circulating a mild acidic solution through the machine. The acid reacts with the calcium carbonate deposits, dissolving them so they can be flushed out. Nespresso recommends using their official descaling kit, which is formulated to be effective yet safe for the machine’s internal materials.
Descaling is not the same as cleaning. Cleaning removes coffee oils and residue from the capsule area, drip tray, and water tank. Descaling targets mineral deposits inside the machine. Both are necessary, but they serve different purposes.
Signs Your Nespresso Citiz Needs Descaling
Your Nespresso Citiz is designed to alert you when descaling is required. The machine’s two cup buttons, Espresso and Lungo, will blink alternately when the descaling cycle is overdue. This is the most reliable indicator that you should descale soon.
Even before the alert appears, you may notice other signs of limescale buildup:
- The coffee tastes weaker, more acidic, or less aromatic than usual.
- The brewing process takes longer than normal.
- Water flow is reduced or inconsistent.
- The machine makes louder or unusual noises during brewing.
- The coffee is not as hot as it used to be.
- The machine takes longer to heat up.
If you notice any of these symptoms, do not wait for the alert. Descaling proactively can prevent further buildup and protect the machine. In areas with hard water, you may need to descale more frequently than the alert suggests.
What You Need Before You Start
Before you begin the descaling process, gather the following items so the procedure goes smoothly:
- A Nespresso descaling kit or an approved descaling solution.
- Fresh water for rinsing.
- A large container or jug that can hold at least one liter of liquid, placed under the coffee outlet.
- A clean cloth or paper towels.
- Access to a sink for emptying the water tank and container.
- Approximately 20 to 30 minutes of uninterrupted time.
Make sure the machine is turned on and has completed its initial heat-up cycle. Remove any used capsule from the lever area and empty the capsule container. It is also a good idea to remove the drip tray and clean it separately.
Choose a location near a sink so you can easily empty and refill the water tank. Descaling produces wastewater that should not be poured down a drain that connects to septic systems without dilution, so check local guidelines if applicable.
Recommended Descaling Solutions
Nespresso strongly recommends using their official descaling kit, which contains two sachets of descaling solution. Each sachet is designed to be mixed with water for one descaling cycle. The formula is tested to be safe for the machine’s internal components and effective at dissolving limescale.
The official kit is widely available from Nespresso boutiques, the Nespresso website, and authorized retailers. Using the official solution also helps preserve your warranty, as third-party products may not be covered if they cause damage.
Some users prefer homemade solutions such as citric acid or white vinegar. While these can dissolve limescale, they may leave odors, damage seals over time, or be less effective at the concentrations used. If you choose a third-party product, ensure it is specifically labeled as safe for espresso machines and follow the manufacturer’s instructions carefully.
How to Descale Nespresso Citiz Coffee Machine?
This section provides the complete step-by-step instructions for descaling your Nespresso Citiz. Follow each step carefully and in order. Do not skip the rinsing phase, as residual descaling solution can affect coffee taste and may be harmful if ingested.
Step 1: Prepare the Machine
Turn on the Nespresso Citiz and wait for it to heat up. The lights on the Espresso and Lungo buttons will stop blinking when the machine is ready. Open the lever and remove any capsule. Empty the capsule container and the drip tray. Place a large container under the coffee outlet to catch the liquid during descaling.
Step 2: Add Descaling Solution and Water
Open the water tank. If using the Nespresso descaling kit, pour one sachet of descaling solution into the tank. Then fill the tank with fresh water up to the maximum level line. Close the water tank lid securely. If using a liquid descaler, follow the dilution instructions on the product label.
Step 3: Enter Descaling Mode
With the machine turned on and ready, press and hold both the Espresso and Lungo buttons simultaneously for three seconds. The lights on both buttons will begin to blink, indicating that the machine has entered descaling mode. This mode changes the machine’s behavior so it can run the descaling cycle.
Step 4: Start the Descaling Cycle
Press the Lungo button once to begin the descaling cycle. The machine will pump the descaling solution through the internal system and out through the coffee outlet into your container. The process takes several minutes. Do not interrupt the cycle. The buttons will continue to blink while the cycle runs.
When the water tank is empty, the machine will stop automatically. Empty the container into the sink. Do not yet turn off the machine.
Step 5: Rinse the Water Tank
Remove the water tank and rinse it thoroughly with clean water to remove any remaining descaling solution. Refill the tank with fresh water up to the maximum level line. Reattach the tank to the machine. Empty the container under the outlet again and place it back.
Step 6: Run the Rinse Cycle
Press the Lungo button again to run a rinse cycle using fresh water. The machine will pump clean water through the system, flushing out any residual descaling solution. Allow the tank to empty completely. If you want extra assurance, refill the tank with fresh water and repeat the rinse cycle once more.
Step 7: Exit Descaling Mode
Once rinsing is complete, press and hold both the Espresso and Lungo buttons simultaneously for three seconds. The blinking lights will stop, and the machine will return to normal operating mode. The descaling alert should now be cleared.
Step 8: Final Check and Clean Up
Empty and clean the container, drip tray, and capsule container. Wipe the machine exterior with a damp cloth. Run one normal brewing cycle without a capsule to ensure the water runs clear and the machine functions correctly. Your Nespresso Citiz is now descaled and ready to use.
Using Third-Party Descaling Products
While Nespresso recommends their official descaling kit, some users prefer third-party descaling products. These are available in powder, liquid, and tablet form. If you choose this route, select a product specifically designed for espresso or coffee machines, and follow the manufacturer’s dilution and usage instructions.
Key considerations when using third-party products include compatibility, concentration, and residue. Some products may be too acidic and can damage internal seals or leave a lingering taste. Always rinse thoroughly after using any descaling product. If you notice a chemical taste or odor after descaling, run additional rinse cycles with fresh water until it disappears.
Keep in mind that using non-approved products may affect warranty coverage if damage occurs. For most users, the official Nespresso descaling kit offers the safest and most reliable results.

- Using vinegar excessively: Frequent vinegar use can degrade rubber seals and gaskets.
- Not emptying the container in time: The container can overflow, creating a mess and potential electrical hazard.
- Interrupting the cycle: Stopping mid-cycle can leave solution trapped inside the machine.
- Forgetting to exit descaling mode: The machine may not brew normally until you exit the mode by holding both buttons.
- Ignoring the descaling alert: Delaying descaling allows scale to harden, making it harder to remove later.
By avoiding these mistakes, you can ensure a safe and effective descaling process every time.
Troubleshooting After Descaling
Sometimes issues arise after descaling. Here are common problems and solutions:
- Coffee tastes sour or chemical: Run additional rinse cycles with fresh water until the taste disappears.
- Machine still shows descaling alert: Repeat the process to ensure you properly exited descaling mode by holding both buttons for three seconds.
- Water flow is still weak: Scale may be severe; repeat descaling or contact Nespresso support.
- Machine will not brew: Ensure the water tank is properly seated and the machine is out of descaling mode.
- Leaking from the machine: Check that the water tank and drip tray are correctly positioned; if leaking persists, contact support.
If problems continue after troubleshooting, reach out to Nespresso customer service for professional assistance.
How Often Should You Descale?
The frequency of descaling depends on your water hardness and usage. Nespresso generally recommends descaling every three months or after approximately 300 capsules, whichever comes first. However, this can vary based on local water conditions.
If you live in an area with hard water, you may need to descale every one to two months. In soft water areas, you might extend the interval to four months. Using filtered or bottled water can reduce mineral buildup and lengthen the time between descaling sessions.
Pay attention to the machine’s descaling alert, but also monitor coffee taste and flow. If you notice changes before the alert appears, descale sooner rather than later. Regular descaling is one of the most important maintenance tasks for keeping your Nespresso Citiz in top condition.
Frequently Asked Questions
How long does it take to descale a Nespresso Citiz?
The entire descaling process, including preparation, the descaling cycle, and rinsing, takes approximately 20 to 30 minutes. The actual descaling cycle runs for several minutes, followed by one or more rinse cycles. Plan for uninterrupted time to complete all steps properly.
Can I descale without the Nespresso kit?
Yes, you can use third-party descaling products or homemade solutions such as citric acid. However, Nespresso recommends their official kit for best results and warranty protection. If you use an alternative, ensure it is safe for espresso machines and rinse thoroughly afterward.
Is vinegar safe for descaling Nespresso Citiz?
Vinegar can dissolve limescale but is not recommended by Nespresso. It may leave a strong odor, affect coffee taste, and potentially damage internal seals over time. If you use vinegar, dilute it well and rinse extensively. For best results, use the official descaling kit.
