Descaling… it’s something that needs to be done, and yet somehow you can’t help the feeling of dread that surfaces when you see that blinking light. Like servicing a car, descaling a Nespresso machine is essential to keep your coffee machine operating at its best and churning out great-tasting coffee. 

Thankfully, Nespresso has made the descaling process straightforward, with all of their machines having a descaling program. So don’t panic if that descaling alert has popped on, and read our guide to Nespresso descaling for step-by-step instructions.

What is Descaling?

You can think of descaling Nespresso machines as performing a deep internal clean. While most of the other routine cleaning tasks focus on the exterior or removable parts, descaling cleans the internal components. But, you may ask, why does this need to be done?

As you will likely know, water is an essential component of coffee. However, water (even filtered water) contains minerals like magnesium and calcium which, over time, can build up inside the coffee machine and form limescale. If left unchecked, this mineral build-up will negatively impact the performance of the machine and also the taste and temperature of the coffee. 

Nespresso recommends descaling every 3 months or every 300 capsules, whichever comes first. Most Nespresso machines have a descaling alert to notify you when this is due; this is usually a blinking light, or on the more upmarket Nespresso machines, an on-screen alert or app to notify you.

Descaling involves running an acidic solution through the Nespresso machine to strip away any limescale. We recommend using the Nespresso descaling kit, which contains a lactic acid solution, to gently eliminate any built-up limescale. The solution is diluted in 0.5 L of water and added to the water reservoir. The descaling process takes around 15-20 minutes to complete.

Signs That Your Nespresso Machine Needs Descaling

Asides from a blinking light indicating your Nespresso needs descaling, there are a few other symptoms that may indicate descaling is due.

  • If you notice your coffee has a burnt or off taste to it.
  • Your coffee is not as hot as normal.
  • Your Nespresso machine is making strange noises when brewing coffee.
  • The coffee is coming out more slowly than normal.

If you notice any of these, the first step in diagnosing the problem should be to descale your Nespresso machine to see if that solves the problem. 

How to descale a nespresso machine

So without further ado, here are the instructions for how to descale your Nespresso machine. No matter what model you have, the process is the same. The only difference will be in how you activate the descaling mode.

Nespresso Descaling Instructions

What you will need:


  1. Prepare The Coffee Machine. First, lift and close the lever to eject the used capsule. Next empty the used capsule container, drip tray, and water tank. Replace the used capsule container and the drip tray.
  2. Make Up The Descaling Solution. Make up the solution according to the instructions. If you are using the Nespresso Descaling Kit this involves filling the water reservoir with 0.5L of water and then pouring in one pack from the Nespresso descaling kit. Replace the water reservoir back into the machine.
  3. Place A Container Under The Coffee Outlet. Don’t forget this step! Place an empty container, with a minimum volume of 1 liter under the coffee outlet to collect the used solution.
  4. Start The Descaling Process. Turn the coffee machine on and put it into descaling mode. How this is done will vary depending on the Nespresso machine model, if you are not sure how to do this, refer to your manual. The descaling process will begin and the machine will run the descaling liquid through the machine. The process takes around 15 minutes to complete.
  5. Run A Rinse Cycle. Once the descaling process is finished, discard the water from the reservoir, drip tray, and container. Rinse and clean these parts thoroughly with warm water to remove any residue solution. Refill the water tank with clean water and reassemble the machine. Replace the empty container under the outlet and push the start button. This will start the first rinse cycle where the machine runs fresh water through it to remove any remaining solution. 
  6. Run a Second Rinse Cycle. Once the rinse cycle is complete, repeat step 5 again and perform a second rinsing cycle. This is important to ensure no solution remains in the Nespresso machine which can contaminate the coffee.
  7. Exit Descaling Mode. Once the second rinse cycle is complete, exit the descaling mode. Rinse and clean the water tank and drip tray, fill the water with fresh drinking water and reassemble the machine. Wipe the machine down with a damp cloth. Leave the Nespresso machine to dry for 10 minutes before use. 

Can You Make Your Own Descaling Solution?

While we recommend you use the Nespresso Descaling Kit which is designed for Nespresso coffee makers, there are other options. You can make your own descaling solution using either lemon juice, citric acid, or vinegar.

  • Lemon Juice: To make a descaling liquid, mix equal parts lemon juice and water. Run the solution through the Nespresso machine as normal and follow with two rinsing cycles to remove any residual lemon juice.
  • Citric Acid: Mix 1 part Citric Acid with 20 parts water and add to the water tank. Run through the descaling program and then follow with 2 rinse cycles. 
  • Vinegar: Make a solution using one part vinegar, and one part water. Run the solution through the Nespresso machine. Following this, you will need to run at least four rinsing cycles to remove the residual vinegar. Note: Nespresso does not recommend you use vinegar as a descaling solution as it can damage the machine.

A Guide to Nespresso Descaling Alerts

If you have a more basic Nespresso machine like the Essenza, Pixie, Inissia, or Citiz you will find that they do not have a descaling alert built in. While it can be hard to remember when to descale your Nespresso machine, you should aim to do this a minimum of once a year. Preferably every 3 months or 300 capsules used as Nespresso recommends. If you have one of the other Nespresso models they will have an alert to notify you when this is due. We have summarized the descaling alerts below: 

  • Essenza Plus: Orange descaling light blinks.
  • Lattissima One/ Touch or Gran Lattissima: Descaling indicator light shines orange.
  • Lattisima Plus: The cappuccino button shines orange.
  • Creatista/ Creatista Plus: Descale your Nespresso machine now alert will appear on the screen.
  • Vertuo: Light blinks alternately 3 times then steady.
  • Vertuo Evoluo: Light blinks alternately 3 times then steady.
  • Vertuo Next: Orange and white light alternately blinking 3 times then steady on.
  • Vertuo Plus: Simultaneous red and green light.
