How to Descale a Nespresso Machine: Vertuo and Original (2026)

Nespresso recommends descaling every 3 to 6 months, or roughly every 300 capsules. The right interval depends mostly on your water hardness. With hard water (above 120 ppm), mineral deposits build up faster and you may need to descale closer to every 3 months. With soft or filtered water, 6 months is reasonable.

Most Nespresso machines alert you when descaling is due. On Vertuo machines, the button blinks orange. On Original line machines, the lights pulse in a specific pattern. When you see that alert, run the descaling cycle before the next brew session. Ignoring it for weeks means slower flow and weaker coffee in the meantime. You can check your machine's specific alert behavior on Nespresso's machine assistance page, which also includes model-specific troubleshooting.

I set a calendar reminder for every 3 months regardless of the alert light. That way the machine never gets to the point where the pump is visibly struggling.

You only need three things. Have them ready before you start and the whole process is straightforward.

The Vertuo line uses Nespresso's Centrifusion brewing technology and reads barcodes on each capsule. Descaling mode on Vertuo machines requires a specific lever-and-button sequence. Follow these five steps in order. The full procedure is documented in Nespresso's official VertuoLine Descaling Guide.

The Original line includes machines like the Inissia, Essenza Mini, Pixie, and CitiZ. These machines brew using a 19-bar pump and standard Nespresso Original capsules. Descaling mode on the Original line uses a simpler two-button combo. The steps below follow Nespresso's official Inissia Descaling Guide, which applies to all Original line machines using the two-button entry.

The Vertuo Next, Vertuo Pop, Lattissima, and Creatista machines each have their own descaling sequences that differ from the standard combos above. Nespresso has not published a universal button combo that covers all of these models, so providing a single verified sequence for them would be misleading.

Machines with a screen or menu (like the Nespresso Creatista Plus and Lattissima series) typically guide you through descaling via on-screen prompts. Navigate to the maintenance or settings menu to find the descaling option. The steps on-screen will walk you through preparation, running the solution, and rinsing.

For the Vertuo Next and Vertuo Pop, the sequence is similar in concept to the VertuoLine combo but the button timing and lever positions can vary. Before descaling one of these machines, confirm the exact steps for your model on Nespresso's official machine assistance page. Enter your model name and the page returns the exact descaling sequence for that machine.

Nespresso recommends using only its own descaling solution. That said, a citric acid substitute works if you do not have the official kit on hand. Dissolve approximately 1 tablespoon of food-grade citric acid in 1 liter of fresh water. Use this solution in place of the Nespresso descaling solution, following the same steps. Citric acid dissolves calcium carbonate effectively, rinses clean, and leaves no aftertaste.

White vinegar is a different case. It does dissolve some scale, but acetic acid absorbs into the rubber seals and internal tubing inside Nespresso machines. Even after multiple rinse cycles, the vinegar taste can persist in your coffee for days. Over time, repeated vinegar descaling degrades the rubber components that form the machine's water-tight seals. Nespresso advises against vinegar specifically, and using it may affect your warranty coverage.

Using a non-Nespresso descaler (including citric acid) may also affect your warranty, depending on when and how the machine fails. If your machine is within its warranty period, the official Nespresso Descaling Kit is the low-risk choice. For out-of-warranty machines, food-grade citric acid is a practical and effective alternative. You can read more about descaling solution choices across all machine types in our guide on how to descale espresso machines.

The rinse cycle is the step people most often rush. After the descaling solution has run through, a full tank of fresh water needs to cycle through the machine before you brew coffee. That rinse carries out the dissolved scale and any remaining descaling solution. Skipping it or running only a partial rinse means your first few capsules will taste off, with a faint chemical or citric note.

After rinsing, you need to exit descaling mode using the same button combo you used to enter it. If you skip this step, the machine stays in descaling mode and will not brew normally. On Vertuo machines, the button will continue blinking as a reminder. On Original line machines, the lights keep pulsing.

Once you exit descaling mode, let the machine rest for about 10 minutes before brewing. The internal temperature stabilizes during that brief rest period and your first cup will taste clean and properly extracted.

If the descale indicator light stays on after you have completed all steps, the machine may not have registered that the full cycle was completed. Run one more fresh-water rinse cycle, then exit descaling mode again. This resolves the issue in most cases. If the light persists, contact Nespresso support for model-specific guidance.

Most descaling issues fall into one of three categories. Here is what to do in each case.
