About My Dolce Gusto Coffee Machine FAQs

The NESCAFÉ® Dolce Gusto® machine pumps water into its capsules at up to maximum 15 bar pump pressure. The high pressure, and the coffee pod design, deliver an even distribution of pressure to extract the coffee’s full flavour.

The system uses a pump pressure similar to that of professional machines, while coffee percolators operate at one bar of pressure (normal atmospheric pressure).

Using a Dolce Gusto® coffee machine is really simple, just head over to our machine care page and select your coffee machine to find out how to make your perfect brew.

Cleaning and Descaling FAQs

Over time, limescale slows waterflow, reduces the capacity and could reduce the effectiveness of heating the water used to make your drinks. 

Descaling every 3-4 months gets rid of the build-up of limescale, keeping water flow fast and pump pressure high. It’s super simple to descale your Dolce Gusto® coffee machine, check out our guide and find out what you need to do.

To maintain the performance of your Dolce Gusto® coffee machine, it’s important to keep it clean in between uses. If you’re wondering which areas of your machine you need to pay special attention to and how to keep it clean and in good working order, read our guide on descaling and cleaning your Dolce Gusto® coffee machine.

You can buy Dolce Gusto® descaler liquid directly from us. We sell descaling liquid, specially designed for use with your Dolce Gusto® machine to keep it running as smoothly as possible.

Most of our coffee machines have an alert to tell you when it needs descaling and after a set number of uses, an orange or amber light will show up, which is the machine’s way of telling you it’s time for descaling. If your machine doesn’t have this feature, make sure to clean it every 3 to 4 months.

Coffee Machine Troubleshooting

If your coffee machine isn’t working, it may be because it needs to be descaled and unblocked. Check out our machine use and maintenance guides to find out how to solve any potential issues.

If you’ve tried descaling and unblocking and are still having problems, please call the NESCAFÉ® Dolce Gusto® hotline free on 0800 707 6066 in the UK or 00800 6378 5385 in ROI.

If water’s leaking outside the machine whilst you’re preparing your drink, it may be due to an insufficient seal between the coffee pod and the machine. To fix this issue follow these steps:

  • Check the coffee pod’s in the holder
  • Stop the machine, wait for the light to stop blinking and remove the coffee pod
  • Make sure the coffee pod’s not been pierced twice
  • Repeat the process with a new coffee pod

If the problem still occurs, contact us or phone us on: 0800 707 6066

Firstly, check that there’s water in the tank, if not, fill the tank and start again. If the problem persists, there may be a blockage. Use the descaling solution recommended for your machine to remedy this. If after following this advice you’re still having issues, get in touch or phone us on: 0800 707 6066

If your coffee machine is displaying a yellow light instead of the usual green one, it’s time for descaling. The machine will do this depending on the number of times it’s been used and regular descaling helps to keep it in good working order. Simply purchase the correct descaling equipment recommended for your machine, run through the descaling process, then the next time you use it, the light will return to green.

Please re-check the box in case the missing part is still in there and, if it is not, please return the entire machine to its point of purchase for a replacement.

If you purchase from the NESCAFE® Dolce Gusto® webshop, please call our hotline free on 0800 707 6066 in the UK or 00800 6378 5385 in ROI.
