In this article, I’ll share my tips on how to Descale a DeLonghi Espresso Machine and also include some information about why descaling is important and how often you should do it.

The Importance of Descaling and How Often To Do It

Descaling your DeLonghi Espresso machine is a crucial maintenance task that should not be overlooked. Over time, mineral deposits from the water supply can accumulate within the machine’s water system. These deposits can lead to a host of issues that can affect both the performance and the flavor of your coffee.

Mineral deposits can clog the machine’s water pipes, making it difficult for water to flow through. It can lead to a decrease in the water flow, affecting the taste of your coffee and making it difficult to extract the desired amount of espresso. If mineral deposits are not removed, they can eventually damage the machine’s internal components. It can lead to costly repairs or even needing to replace the appliance.

Mineral deposits can also affect the taste of your coffee. They can make your coffee taste sour or bitter and interfere with the extraction process, resulting in a weaker cup of coffee. The frequency with which you need to descale your machine will depend on the hardness of your water. You must descale your machine every 3-4 months if you have hard water. If you have soft water, you may only need to descale your appliance once a year.

How To Descale Delonghi Espresso Machine (Simple Steps)

Ensure that you read and understand the manual with your DeLonghi espresso machine. Each model has a different design, and descaling processes may differ according to these features.


Gathering all the needed materials before you begin descaling your DeLonghi espresso machine is important. To descale your DeLonghi espresso machine, you will need the following:

  • DeLonghi or a homemade descaling solution
  • Clean water – freshness is key for that perfect brew!
  • A container to mix the descaling solution and water – we’re about to create some espresso magic!
  • A trusty cloth or sponge to wipe down the machine’s exterior – a little cleaning never hurts!
  • Don’t forget a towel or cloth to catch any potential spills – better safe than sorry.

Ensure the espresso machine is turned off and unplugged to prevent any accidents during the descaling process. Remove any coffee grounds or leftover coffee from the portafilter and group head.

Empty the water tank and remove the water filter

The first step to descaling your DeLonghi espresso machine is to empty the water tank. If the tank is removable, remove it and empty its contents. If the tank is not removable, use a measuring cup or pitcher to scoop out the water.

Pro Tip: If you have hard water, rinse the water tank with vinegar before emptying it. It will help remove some limescale deposits that can build up over time.

Prepare Your Descaling Solution

Once the water has been emptied, you need to prepare the descaling solution. The descaling solution is made up of water and a descaling agent. Remember to be careful not to spill the descaling solution. If you spill the descaling solution, be sure to wipe it up immediately. The descaling solution can be corrosive and damage surfaces if not cleaned up properly.

To prepare your descaling solution, you have several options. Concentrated solutions typically mix 1 part descaler with 1 part water. Tablets may require dissolving a certain number in water, like 2 tablets in 500ml. For a natural approach, use 1 part white vinegar to 1 part water. Some brands offer ready-to-use solutions, while others provide pre-measured packets.

Always follow the product instructions for accurate measurements and safe descaling of your espresso machine.

Fill the water tank with a Mixture

The descaling solution should be poured into the water tank after the descaling solution has been prepared. If the water tank can be removed, place it back in the machine.

Start Descaling

Turn on your espresso machine and select the descaling cycle and the process will start automatically. The descaling cycle will vary depending on the model of your espresso machine. Using your user guide, determine how to start the descaling process. Typically it takes around 30 minutes. However, the exact time may vary depending on the model of your machine and the severity of the limescale buildup.

Every Delonghi Espresso Model is different. Make sure to follow the instructions on the label. This will help to ensure that you descale your machine properly and avoid damaging it.

Run the Machine with Clean Water

After the descaling cycle, rinse the water tank thoroughly, fill it with clean water, and run the machine again. This will help to remove any residual descaling solution from the machine.

To run the machine in order to Rinse it, just press the Settings button and choose the Rinse option displayed on the screen. This function will deliver hot water from the coffee spouts to clean.

Repeat the Process

It is possible that you will need to repeat the descaling process more than once, depending on the severity of the scale buildup. After each descaling process, be sure to rinse the water tank and run clean water through the machine.

Descaling a DeLonghi Espresso Machine with Other Alternative Products

While it’s recommended to use a descaling solution specifically designed for espresso machines, you can try some other handy alternatives. Citric acid is a natural and safe descaling solution that can remove limescale buildup from your DeLonghi espresso machine. Here’s how to do it:

  • Ingredients
  • Citric Acid – 1 tbsp
  • Water – 2 Liter


  • Take 1 tablespoon of citric acid with 1 liter of distilled water to prevent the citric acid from reacting with any minerals in the water, which could reduce its effectiveness.
  • You can now add the solution to your DeLonghi espresso maker’s water tank.
  • Start your DeLonghi espresso machine and let it run for a few minutes or until half the solution is gone.
  • Allow the solution to sit inside your DeLonghi espresso machine for 20-30 minutes before turning it back on.
  • The rest of the solution will run through your DeLonghi espresso machine as soon as you turn it on again.
  • After the solution has passed through the machine, rinse the water tank and fill it with clean water.

If any solution remains in the engine, Rinse the machine thoroughly after descaling. This will help to remove any residual citric acid solution from the machine. Be careful not to overfill the water tank. If you fill the tank, the citric acid solution could overflow and damage the machine.

How To Clean Delonghi Espresso Machine

This is important to do regularly to prevent the build-up of these substances, which can affect the taste of your coffee.
