In this blog, I previously covered how to clean a Dolce Gusto coffee machine. However, we unintentionally omitted a vital aspect of the cleaning process: descaling the machine. Descaling is an essential step that should not be overlooked in maintenance.
It is easy to overlook the descaling process when purchasing a new Dolce Gusto capsule coffee machine. The only maintenance requirements are typically cleaning the exterior, changing the water in the tank, and emptying the drip tray.
As a result, many coffee machine users are unaware that their machine must be descaled regularly. Only when the orange light begins to flash do most Dolce Gusto coffee machine users decide to descale their machine, despite several other situations where descaling is necessary, such as correcting water pressure issues or improving coffee flavour.
What do I need to descale a Dolce Gusto coffee machine?
You don’t need a long list of items when it comes to descaling your Dolce Gusto coffee machine. However, it’s recommended to have the following items at hand:
- A container with a capacity greater than half a litre that can fit under the machine’s spout
- A bottle of descaling liquid specifically designed for Dolce Gusto machines or 250ml of another brand that is suitable for coffee machines
- A nearby water tap for rinsing all the components and refilling the water tank.
Although this process may be unfamiliar, the descaling liquids are specially formulated to remove limescale build-up from the machine’s water system.
The official Dolce Gusto descalers are made by the Swiss brand Durgol and come in a two-unit kit, each containing 125ml. The cost is approximately £12 for the kit. Alternatively, there are other suitable products available in the market as well:
- De’Longhi EcoDecalk Descaler for Coffee Machines DLSC500, 500ml
- EcoZone Multi-Purpose Appliance Descaler
When should I descale my Dolce Gusto coffee machine?
Most modern coffee pod machines now have a warning light to indicate when a descaling process is necessary. In the case of Dolce Gusto machines, the power button illuminates in orange to notify the user that the machine needs to be descaled.
Nevertheless, there are several noticeable indications that your Dolce Gusto coffee machine requires descaling:
- The drink is not as hot as it previously was.
- No or very little water comes out of the machine.
- The taste of the coffee is no longer as rich and strong as before.
If you experience any of these signs, it is recommended to descale your Dolce Gusto coffee machine as soon as possible.
How to descale a Dolce Gusto coffee machine
The step-by-step process for descaling your Dolce Gusto coffee machine is straightforward to follow. It is crucial to follow each step carefully to ensure the best possible outcome of the descaling process.
- Begin by emptying the coffee pod holder before starting the descaling process.
- Next, empty the water tank and fill it with half a litre of clean cold water using the container suggested in the previous section.
- Add the 250ml descaling liquid with the previously added water into the tank.
- Place the container under the coffee machine’s spout and position the water tank with the mixture.
- With the coffee maker turned off, press the power button for 5 seconds until the green light starts flashing (or in manual models, the light flashes orange).
- Select the largest coffee size and turn the brew lever to the hot water position to start the descaling process.
- The machine will pour water for approximately two minutes, and once it finishes, the green light will flash for another 2 minutes. Once it remains steadily green, the descaling process is complete.
- Rinse the machine by rinsing the water tank to remove any residual descaler and preparing several coffees without a capsule to clean the entire internal circuit.
Following these steps will help you quickly descale your Dolce Gusto coffee machine, enabling you to enjoy the perfect flavour of your coffee.
