A Guide To The Delonghi Magnifica Descaling Process

The water used to brew coffee causes lime scale and calcium mineral buildup inside your Delonghi Magnifica machine. While not toxic, these can block the unit’s water flow and impact temperature and overall performance. It can affect the taste of your coffee too. Descaling is the name of the cleaning process that removes these minerals to extend the life of your Delonghi espresso machine. Keep reading to find instructions on how to clean and descale a Delonghi Magnifica espresso machine.

How Often To Descale Delonghi Magnifica Espresso Machines

Your Delonghi espresso maker will have a pair of flashing lights that will turn on when it is time to descale. One light will look like water drops and the other will show triangles. Some models like the Magnifica S may only have the triangles. You will still be able to brew coffee after this light has come on, but you should descale as soon as possible.

However, you don’t have to wait for this light to turn on. A good rule of thumb is that a you should descale your coffee maker after 3 months or 90 uses, whichever comes first.

This is true if you are using filtered water, bottled water or tap water with a low to normal mineral count. You should clean your Delonghi espresso machine more often if your tap has “hard water,” meaning it contains higher level of minerals. If you are not sure about the level of minerals in your water, you can get a low-cost water testing kit. This will allow you to set the water hardness level on your Magnifica machine so that the descale alert activates at the right time.

Can You Descale Delonghi Espresso Machines With Vinegar Or Another DIY Solution?

You should not use water and vinegar for cleaning an espresso machine made by Delonghi. White vinegar contains 5-8% acetic acid and apple cider has 5-6%. This type of acid can wear down metal and cause leaks. Plus, vinegar cannot remove oils left by used coffee beans.

Instead, the best way to clean an espresso machine is with a descaling agent made by Delonghi. It has safe and effective types of cleansers, like lactic or citric acid, that won’t damage your brewer. Using DIY solutions to clean your De’Longhi may damage your machine and void your warranty.
