Avoid Limescale Buildup on Your Delonghi Espresso Machine

Keeping your Delonghi espresso machine free of limescale buildup is key to ensuring that it works properly. Limescale can clog up valves and tubes, interfere with the taste of your coffee, and even damage the heating element if left too long. 

The best way to avoid this is to regularly descale and clean your machine with a mild detergent solution. Additionally, use only water that has been filtered or softened, as hard water will exacerbate limescale buildup. 

How Often Should I Descale My Delonghi Magnifica?

Regular descaling of your Delonghi Magnifica espresso machine is essential for optimal performance and longevity. On average, it’s recommended to descale it every 3-4 months, depending on the mineral content of the water in your area. 

Descaling keeps your machine from being clogged by calcification and removes tastes and odors caused by calcium buildup. It can be done quickly with a descale liquid, powder, or tablet that can easily be found online or in stores. 

Furthermore, the process may cause a bit of a mess. Following the manufacturer’s instructions will ensure that you get between two to three years more out of your Delonghi Magnifica before needing any major maintenance.

The Benefits of Descaling a DeLonghi Espresso Machine 

1. Improved Flavor Quality 

Descaling your DeLonghi espresso machine helps improve the quality of the flavor of the coffee produced by your machine. Also, you will feel that steam milk quality is improved.

Limescale buildup can cause bitter or sour flavors in your coffee, as well as cause mineral deposits to form on the metal parts inside your machine.

Which can affect its performance and taste. By regularly descaling your DeLonghi espresso machine, you can make sure that you’re getting the full flavor out of every cup of coffee you brew with it. 

2. Longer Lifespan 

A regular descale will help to extend the lifespan of your DeLonghi espresso machine by removing built-up lime scale from inside its components. It also helps in preventing further damage from occurring due to corrosion or other wear and tear caused by mineral deposits. 

If left unchecked, this build-up could eventually lead to serious mechanical issues with the machinery that would require costly repairs or replacements in order to be fixed. 

Regular descales will help ensure that these problems never arise so you get maximum use out of your DeLonghi espresso machine for years to come. Meanwhile, you should also reset the Delonghi espresso machine sometime after descaling.

3. Improved Efficiency 

Descaling will help improve efficiency because it removes any limescale build-up from inside the components of your DeLonghi espresso machine. 

That could slow down its performance and cause it to take longer than necessary to produce a cup of coffee. This means less waiting time for you between cups and more convenience overall when using your DeLonghi espresso maker.

Frequently Asked Questions (FAQ)

Does Scaling Affect My Coffee’s Cream Layer?

It depends on the coffee. Arabica beans have a more delicate flavor and will be affected more by scaling than Robusta beans which have a higher caffeine content and a stronger flavor. The crema of the espresso is mainly composed of oils from the coffee bean, so if your coffee machine isn’t cleaned regularly, those oils will build up and create a thicker cream layer. 

What is the Proper Amount of Scaling Solution to Use on Delonghi?

You should use 2 tablespoons of scale remover per gallon of water. Soak the coffee maker in the solution for about 15 minutes, then rinse it with clean water. You can also try using a vinegar and water mixture to clean your coffee maker. 


In a nutshell, In order to keep a DeLonghi Espresso Machine operating smoothly and efficiently for many years to come, it needs to be descaled regularly. 

Not only does it improve flavor quality. But it also helps extend its lifespan by preventing mechanical issues caused by mineral deposits and corrosion. As well as improving efficiency by eliminating build-up that could slow down performance time. If you are using our other preferred brand, JURA, check out our article on how to descale a Jura here.
