How to descale a Dolce Gusto coffee Machine

We have already covered in our blog how to clean a Dolce Gusto coffee machine, but in that article, we left out one of the most important parts of the cleaning process of a coffee machine; the process of descaling the Dolce Gusto coffee machine.

You do not consider descaling when buying a Dolce Gusto capsule coffee machine. If the machine is brand new, there is no point worrying about maintenance beyond cleaning the exterior, the drip tray and changing the water in the water tank. Many coffee machine users did not even know that the machine had to be descaled regularly.

There can be several different situations why you need to descale your coffee machine, from solving a problem with the water pressure to improving the taste of the coffee. However, most Dolce Gusto coffee machine users only decide to descale their coffee machine when the blinking orange light appears.

What do I need to descale a Dolce Gusto coffee machine?

To descale a Dolce Gusto coffee machine, you don’t need many items, as the most important thing in decalcifying is not the materials but following the steps correctly. In any case, you should have the following items ready:

  • A container with a capacity greater than half a litre can be placed under the spout of the coffee machine.
  • A bottle of descaling liquid specifically for Dolce Gusto, or 250ml of another brand, but suitable for coffee machines.
  • A water tap is nearby to rinse all the components and refill the water tank.

This process may be new to you, but these are special liquids that remove all the limescale deposited in the water system when mixed with water and run through the machine. The official Dolce Gusto descalers are made by the Swiss brand Durgol and are sold in 2 x 125ml units and are about £12 for a two-unit kit. Here are some good products:

When should I descale my Dolce Gusto coffee machine?

Unlike other brands, Dolce Gusto coffee machines did not have an automatic alarm or warning system until a few years ago to tell us when to descale the machine. The first models to incorporate descaling warnings were the Jovia and Oblo, using the familiar orange light on the power button.

However, there are several unmistakable signs that our Dolce Gusto coffee machine needs to be descaled:

  • The drink is not as hot as it used to be.
  • No or very little water comes out.
  • The taste of the coffee is no longer as pure and strong as before.

If you encounter any of these signs, do not hesitate to descale your Dolce Gusto coffee machine as soon as possible.

How to descale a Dolce Gusto coffee machine

The step-by-step process outlined below is easy to follow, so you should have no problem locating your Dolce Gusto coffee machine. It would be best if you didn’t skip any of the steps. Otherwise, the result of the descaling process may not be the desired one.

  • Check the capsule holder, making sure it is empty before starting the descaling process.
  • Empty the water tank and, using the container indicated in the previous section, fill it with half a litre of clean cold water.
  • Add the 250mml descaling liquid into the water tank and the previously added water.
  • Place the container under the coffee machine’s spout and the water tank with the mixture.
  • With the coffee maker switched off, press the power button for 5 seconds until the green light starts flashing (in manual models, the light flashes orange).
  • Select the largest coffee size and turn the brew lever to the hot water position.
  • The descaling process has started, and the machine will pour water for approximately two minutes. Once it has finished with the water, the green light will flash for another 2 minutes. Once it stays steady green, the process is finished.
  • Rinse the machine; on the one hand, rinse the water tank so that no descaler remains; on the other hand, prepare several coffees without a capsule to clean the entire internal circuit.

This is how easy it is to descale a Dolce Gusto coffee machine. Now you can enjoy coffees with the best possible flavour.
