Step 1: Disassemble, wash, reassemble.

Take your machine apart – remove its lid, drip tray, capsule container – and give each of these components a good, thorough soap wash in warm water. While you leave them out to dry after rinsing them, wipe down the body of your machine with a damp, soapy cloth.

Once all the components have dried up, it's time to reassemble them so the descaling process can begin.

This step will take about an hour.

Step 2: Prepare your Nespresso Descaling Kit

The Nespresso Descaling Kit is designed to gently eliminate the limescale that builds up in your machine over time, so your coffee tastes great today as it did on the first day.

Put in 100ml of Nespresso's descaling agent into the water tank of your machine, before filling the rest with clean water.

Step 3: Start the descaling process.

Make sure that your machine is set to its Descaling Mode. This usually involves holding down both Espresso and Lungo buttons for a few seconds. Once the buttons begin to blink, press the Lungo button to allow the descaling agent to run through your machine and fill up your cup, as you would a cup of coffee. Once it's filled, pour its content back into the water tank to repeat the rinsing cycle.

Descaling Mode differs from machine to machine. To find out how to enter Descaling Mode on your machine specifically, refer to our guide.

Step 4: Run it through clean water.

Carefully clean the water tank and wipe down the inside of your machine to remove all traces of the descaling agent.

Finally, fill up the water tank with clean water to flush out any remaining agent.

Step 5: Fill, pour, fill, pour.

Similar to Step 3, set your machine for a regular, full cup of coffee. Then, pour it away and have your cup filled again. Repeat this process until you've depleted two full, water-filled tank, as that's the amount needed to flush your machine properly.

Step 6: Taste-testing.

Once you're convinced that you've flushed your machine properly, perform a taste test. See if you could taste any of the remaining descaler agents in the water. If you could, that means you'll have to flush your machine once more.

Repeat this tasting-and-flushing process until you can't taste the agent anymore.

Step 7: Coffee time!

Make yourself a cup of coffee, because its time your machine worked hard for you in return.
