How to protect your Delonghi coffee machine against limescale?

Scaling is one of the reasons that stops your Delonghi coffee machine from working. Due to using excessive energy to heat the water, the scaling is built up near the heating area of the machine and this area of your coffee machine quickly breaks down.

You can protect your Delonghi coffee machine from the consequences of hard water with a water softener.

Can scale get into my coffee?

If scaling appears in your Delonghi coffee machine, you need to descale it soon, otherwise, a small number of scale particles get into your coffee.

Though the scale is not harmful to your body but it can change the taste of your coffee because it includes various minerals.

Can I use vinegar to descale my DeLonghi espresso machine?

Citric acid is the main ingredient to descale DeLonghi espresso machines. So while you clean your coffee maker, you need to use such products which include citric acid.

If you do not have this kind of product around you, you have to purchase it. But I never encourage you to use vinegar on a regular basis for descaling your DeLonghi espresso machine.

Vinegar contains acetic acid which can harm the pipes within your machine. The pipes can be leaked and slowly you will be down.

If you need to use vinegar, first you should mix it with water then use. I always recommend applying a descaling solution.

How much vinegar do you use to descale?

Mix 16 ounces of white vinegar with clear water and pour the mixer into the coffeemaker.

Next, you need to start boiling. Some people say that vinegar keeps a sour taste. Usually, it keeps if you do not rinse the kettle off the machine properly.

Is descaling solution better than vinegar?

If you use the DeLonghi espresso machine every day, it will be better to clean it every day with normal water.

After using it it will be hot so that you can easily clean it with a damp sponge and water.

But if you do not clean it every day, scaling will stick on different parts of the machine. So, you need to use a descaling solution.

Many people use vinegar in place of this solution. While you use vinegar, you need to use it with water in the proper ratio.

If you do not maintain the ratio, it causes leakage issues in the coffee machine. For safety, I will recommend using a descaling solution instead of vinegar.

How do you unclog a DeLonghi espresso filter?

The DeLonghi espresso machine can work well if you clean it regularly. But if a clog appears in the filter of the machine, it is needed to remove the entire unit to clean the clog and reinstall again.

If you clean the filter regularly after use it will be good. After use, the filter is warm so it is easy to clean.

 Following are some ways to clear clogs from the filter:

Start The Steam Cycle

Steam is most powerful for cleaning clogs from the filter of the DeLonghi espresso machine.

To produce steam, you need to pour water into the tank of the coffee maker and turn the steam selector knob to steam, and start boiling the water.

If the steam nozzle does not work, switch off the steam selector and clean the nozzle with a pin.

Clean the entire machine

To clean the entire machine, you need to add water to the tank and dip a descaling tablet into it. Usually, these tablets come with the machine but they also can be available in offline and online stores.

Next, close the lid of the tank. Select “Program” from the program selector, then select “descaling.” press the start button. You should keep a container under the nozzle.

How often should I descale my DeLonghi coffee machine?

If you keep your coffee maker with harder water, then it builds up minerals and you will start to face some issues.

The common problems that users experience are reducing the water flow, changing the taste of coffee, leaking, noises, reducing the water pressure, etc.

Usually, every De’Longhi coffee machine tells you when you need to descale it but I always suggest cleaning it every week.


Cleaning your DeLonghi espresso machine regularly is important to keep it in working condition. It not only increases the lifespan of your machine, but it is also important for the taste of your coffee.
