Signs Your DeLonghi Espresso Machine Needs Descaling

If you're a proud owner of a DeLonghi espresso machine, ensuring its proper maintenance is essential to consistently enjoy your favorite brews. One crucial aspect of maintenance is descaling, which removes mineral buildup that can affect your machine's performance and the taste of your espresso. Here are some signs that indicate your DeLonghi espresso machine is due for descaling:

Poor Espresso Quality

If you notice a decline in the taste and quality of your espresso, such as a bitter or sour flavor, it could be a sign of mineral buildup affecting the extraction process. You may also notice inconsistencies in crema formation or a lack of richness in the flavor profile, indicating that descaling is necessary to restore optimal brewing conditions.

Unusual Noises

Another indication that your coffee machine needs descaling is the emergence of unusual noises during operation. Mineral buildup can cause components such as the pump or boiler to work harder than usual, resulting in loud or irregular noises. These noises may signify that the machine struggles to function optimally due to mineral deposits. Descaling can help eliminate these deposits, restoring smooth and quiet operation.

Slow Brewing

If you notice that your DeLonghi espresso machine is taking longer than usual to brew an espresso, it could be a sign of mineral buildup within the machine's internal components. As mineral deposits accumulate, they can obstruct water flow through the machine, causing brewing times to increase significantly. Descaling removes these obstructions, allowing water to flow freely and ensuring prompt and consistent brewing.

Materials Needed for Descaling

Materials Needed for Descaling outlines the essential components required to effectively descale a DeLonghi espresso machine. These include DeLonghi descaling solution, which is specifically formulated to remove mineral deposits and scale buildup from internal components.

DeLonghi Descaling Solution

Delonghi offers specially formulated descaling solutions designed to remove mineral deposits and limescale buildup from the internal components of your coffee machine. Using a manufacturer-recommended solution helps maintain the integrity of your appliance and ensures thorough descaling.


Pure, clean water is essential for the descaling process. You'll need water to dilute the descaling solution and to rinse the internal components of your coffee maker thoroughly. Using distilled or filtered water can help prevent additional mineral buildup.

Soft Cloth

A soft, lint-free cloth is necessary for wiping down the exterior of your coffee machine after the descaling process. This helps remove any residue or descaling solution that may have splashed or dripped onto the surface, keeping your appliance clean and well-maintained.

Preparing Your DeLonghi Espresso Machine

Your DeLonghi espresso machine is not just a kitchen appliance; it's the gateway to your daily dose of rich, aromatic espresso. However, to ensure its longevity and peak performance, it's crucial to start with proper preparation. Here's a closer look at the essential steps:

Turn Off and Unplug

Before any maintenance or cleaning, prioritize safety by turning off your De'Longhi espresso machine and disconnecting it from the power source. This simple yet crucial step prevents any accidental activation during the cleaning process, keeping you safe from electrical mishaps.

Empty Water Reservoir and Drip Tray

Next, remove the water reservoir and drip tray from your DeLonghi espresso machine. Emptying these components helps prevent spills and ensures that the descaling solution can effectively reach all parts of the machine's internal system.

Remove Coffee Grounds

Dispose of any remaining coffee grounds in your DeLonghi espresso machine's portafilter and brewing chamber. Removing the coffee grounds prevents them from interfering with the descaling process and ensures thorough cleaning of the machine's brewing components.

Step-by-Step Descaling Process

Descaling your coffee maker is an essential maintenance task to ensure optimal performance and the longevity of your machine. Follow these simple steps to descale your coffee maker effectively:

Mixing Descaling Solution

Start by following the manufacturer's instructions to mix the appropriate commercial descaling solution with water in a separate container. Ensure that the solution is well-dissolved before proceeding to the next step.

Filling the Water Reservoir

Carefully pour the descaling solution and hot water into the water reservoir of your espresso machine. Be sure to fill the reservoir according to the manufacturer's guidelines, not to overfill.

Running the Descaling Cycle

Turn on your DeLonghi espresso machine and initiate the descaling cycle as outlined in the user manual. This typically involves pressing specific buttons or following menu prompts to begin the descaling process. Allow the machine to run the descaling cycle until the solution has flowed through the internal components.

Flushing with Clean Water

Once the descaling cycle is complete, empty the water reservoir and refill it with clean, fresh water. Run a few cycles of plain water through the machine to thoroughly rinse any remaining descaling solution. This helps prevent any residual taste or odor from lingering in your espresso.

Frequency of Descaling

Typically, it's recommended for appliances like coffee makers and kettles to descale every one to three months, considering usage and water hardness. Regular descaling maintains efficiency and extends appliance lifespan, ensuring consistent results.

Recommended Descaling Schedule

Depending on usage and water hardness, it is generally recommended to descale your DeLonghi espresso machine every 1-2 months. Following a regular descaling schedule helps prevent mineral buildup and ensures the optimal performance of your espresso machine over time.

Factors Affecting Frequency

Several factors can affect how often you must descale your DeLonghi espresso machine. These include the hardness of the water in your area, the frequency of use, and the type of coffee beans you use.

Hard water with high mineral content may require more frequent descaling, while soft water may allow longer intervals between descaling cycles. Additionally, heavy usage of the machine or using oily, dark-roasted coffee beans can contribute to faster mineral buildup and necessitate more frequent descaling.

Importance of Rinsing

Rinsing is an indispensable practice in maintaining the performance and taste integrity of your DeLonghi espresso machine, particularly after the descaling process. It serves two primary purposes:

Removing Residual Descaling Solution

Rinsing your DeLonghi espresso machine after descaling is crucial for removing any residual descaling solution and cleaning solution from the internal components.

Leaving the solution behind can affect the taste of your espresso and may lead to unwanted chemical residues in your beverages. Thorough rinsing ensures that your espresso machine is free from any lingering descaling solution or soap residue, preserving the flavor and quality of your espresso.

Ensuring Cleanliness

Rinsing also clears away loosened mineral deposits and debris, preventing clogs and maintaining smooth machine operation. Regularly cleaning and purging the steam wand after each use helps prevent milk residue buildup and ensures the machine's continued performance and hygiene.


Maintaining DeLonghi espresso machines, we emphasized the significance of regular maintenance and effective descaling. Knowing how to clean DeLonghi espresso machine is essential for ensuring its optimal performance and longevity.

Regular descaling, a critical maintenance task, involves mixing a descaling solution, running a descaling cycle, and flushing with clean water. This process eliminates mineral deposits that can compromise the machine's performance and taste of espresso. Equally important is regular maintenance, which prevents issues like clogging and poor extraction, ensuring the machine's longevity.

By adhering to a maintenance routine and understanding the descaling process, users can sustain the optimal performance of their DeLonghi espresso machines, guaranteeing consistently delicious espresso with every brew.
