How To Run A Delonghi Dinamica Descale Cycle The Right Way

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

Delonghi Dinamica Descale Frequency

An alert on your Delonghi Dinamica espresso maker will start flashing when it is time to descale. It will look like a bunch of triangles in between two lines. You will still be able to brew espresso 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 descale your Delonghi Dinamica 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 Dinamica machine so that the descale alert activates at the right time.

Can You Descale Delonghi Dinamica With Vinegar?

You should not use water and vinegar for descaling Delonghi Dinamica machines. 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 espresso beans.

Instead, the best way to descale a Dinamica 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 descale your De’Longhi may damage your machine and void your warranty.

  1. Turn the machine off. Empty the drip tray and grounds container. Empty

What To Do If the Delonghi Dinamica Descale Light Still Flashes After Descaling?

You can repeat the process, this time using only water from start to finish and no solution. Note that it is also critical that you fill the tank to the MAX line during every rinse cycle. If you don’t additional rinse cycles will be required to make sure there is no residue left in the machine.
