To descale a Nespresso Vertuo Next, empty the capsule container and drip tray, add one unit of Nespresso descaling liquid plus 0.5 L (17 fl oz) of water, and place a container of at least 1 L under the outlet. Enter descaling mode with the 7-second button sequence below, then complete both the descaling and fresh-water rinse stages. Allow about 20 minutes, plus 10 minutes for the machine to dry.
Quick answer
The part most people miss is the 45-second setup window. After the first 7-second hold, the button flashes rapidly. Within 45 seconds, lock and unlock the head, hold the button for another 7 seconds while the lever is unlocked, then lock the machine and press the button once to begin. Do not unplug the Vertuo Next once the cycle has started.

Before you begin
This procedure is for the Nespresso Vertuo Next with the single top button and mechanical locking lever. Do not use the instructions for Vertuo Plus, Vertuo Pop, Evoluo, or an Original-line machine: their controls and maintenance sequences differ. If the label under your machine identifies a different Vertuo model, use that model’s manual.
Nespresso states that its descaling solution can irritate eyes and skin and may damage surfaces. Keep the liquid away from children, wear suitable protection if you have sensitive skin, and wipe spills immediately. Never open the head while water is flowing.
Important: the official manual says descaling mode cannot be interrupted or exited midway. If the machine is unplugged during the procedure, it returns to descaling mode when restarted and both the descaling and rinsing stages must be repeated.
What you need
- One unit of Nespresso descaling liquid.
- 0.5 L (17 fl oz) of water for the descaling mixture.
- Enough fresh drinking water to fill the tank for the rinse.
- A heat-resistant container holding at least 1 L (34 fl oz).
- A clean, dry cloth for any water that collects around the machine head.
Use the manufacturer’s descaling kit rather than vinegar, bleach, dish soap, or a mixture of household chemicals. Cleaning removes coffee residue; descaling dissolves mineral deposits inside the water path. Running a normal cleaning cycle is not a substitute for the programmed descaling cycle.
How to descale a Nespresso Vertuo Next
1. Empty and prepare the machine
- Remove and empty the drip tray and used-capsule container, then reinstall them.
- Open the machine head so any capsule is ejected. Never run the descaling program with a capsule inside.
- Close the head. For now, leave the lever in the unlocked position, pointing toward the front of the machine.
- Pour one unit of Nespresso descaling liquid into the water tank and add 0.5 L of water.
- Reinstall the water tank and place a container of at least 1 L beneath the coffee outlet.
2. Enter descaling mode
- Turn on the machine. The light flashes while the Vertuo Next heats; wait until it becomes steady.
- With the machine closed and the lever still unlocked, press and hold the top button for at least 7 seconds. The button should begin flashing rapidly.
- You now have 45 seconds to finish entering descaling mode. Turn the lever left to the locked symbol, then turn it right again to unlock.
- While the lever is unlocked, press and hold the button again for at least 7 seconds.
- Turn the lever left to lock the machine. The Vertuo Next is now ready to start the programmed cycle.
3. Run the descaling stage
- Confirm the collection container is centered below the outlet and the machine is locked.
- Press the button once. Water should begin flowing after the machine prepares the cycle.
- Let the program run without opening the head, pressing the button again, or disconnecting power. The machine stops automatically when the first stage is complete.
The pump may change pitch and the flow may pause during the program. That alone does not indicate a fault. Stop using the machine only if you see an electrical problem, smell burning, or find water leaking from inside the body rather than into the drip tray.
4. Complete the fresh-water rinse
- When the first stage stops, remove and empty the collection container.
- Remove the water tank, discard any remaining solution, and rinse the tank thoroughly.
- Rinse the drip tray and cup support. Reinstall all removable parts correctly.
- Fill the water tank with fresh drinking water and return the empty 1 L container beneath the outlet.
- Press the button once to start rinsing. The machine completes and stops the rinse automatically.
5. Finish the procedure
- Wait until the rapidly flashing button becomes steady. This confirms that the programmed descaling procedure is complete.
- Empty the collection container and check for water around the visible area inside the machine head. If present, wipe it with a clean, dry cloth.
- Allow the Vertuo Next to dry for 10 minutes before brewing coffee.
What the Vertuo Next lights mean during descaling
| Light pattern | Meaning |
|---|---|
| Orange and white alternates three times, then steady | The machine is requesting descaling. The manual warns that only a limited number of brews may remain before descaling becomes necessary. |
| Orange flashing very rapidly, about three times per second | The machine is performing a descaling or system-emptying program. |
| Rapid flashing after the first 7-second hold | The 45-second window for completing the descaling-mode sequence is open. |
| Steady light after rinsing | The cycle has completed and the machine can dry before its next use. |
Other orange patterns can indicate a different condition. If your main problem is an unexplained warning light rather than routine maintenance, return to the Vertuo Next troubleshooting hub and identify the exact blink pattern before starting another cycle.
If Vertuo Next descaling will not start or finish
| Symptom | Most likely check |
|---|---|
| The machine returns to ready mode | The 45-second setup window probably expired. Start again and complete the lock, unlock, second 7-second hold, and final lock within that window. |
| The cycle does not begin | Confirm there is no capsule, the head is fully closed, the lever is locked for the final start, the tank is seated, and you pressed the button once. |
| No water flows | Check that the tank contains the prepared mixture and is seated correctly. Do not repeatedly run a dry pump. If the full tank is recognized but no water moves, stop and contact Nespresso support. |
| The machine returns to descaling after being unplugged | This is expected behavior described in the manual. Restart the complete descaling and rinsing procedure rather than attempting a factory reset midway. |
| The light keeps flashing after the solution stage | The rinse is still required. Rinse and refill the tank with fresh water, reinstall it, and press the button to complete the automatic rinse. |
| Water is visible inside the head after rinsing | The manual notes that this can occur. Once the machine has stopped, dry only the visible accessible surfaces with a clean cloth. |
How often should you descale a Vertuo Next?
Descale when the machine displays its descaling alert. Water hardness and usage affect how quickly mineral deposits accumulate. An official Krups support page for the Vertuo Next recommends descaling at least every three months for an average of four coffees per day with hard water, and more often in very hard-water areas. Treat that as a maintenance guide, not a replacement for the machine’s alert.
Between descaling sessions, use fresh drinking water and run the normal rinse/cleaning procedure when coffee residue accumulates. Browse the Nespresso troubleshooting database for model-specific maintenance information, or view all coffee-machine guides.
Frequently asked questions
How long does Nespresso Vertuo Next descaling take?
The official manual gives an approximate program time of 20 minutes. Allow another 10 minutes for the machine to dry before using it.
How much water do I use?
Mix one unit of Nespresso descaling liquid with 0.5 L (about 17 fl oz) of water for the first stage. Use fresh drinking water for the separate rinse stage.
Can I descale a Vertuo Next with vinegar?
The Vertuo Next manual instructs owners to use the Nespresso descaling kit and warns against other products. Vinegar can leave an odor, uses an unverified concentration, and does not complete the electronic sequence by itself. Follow the model-specific instructions instead.
How do I exit descaling mode?
Complete both the solution stage and the fresh-water rinse. The manual states that descaling mode cannot be exited midway; disconnecting power causes the machine to return to the program when restarted.
Is the three-button-press cleaning cycle the same thing?
No. Pressing the button three times within two seconds starts the normal cleaning cycle. Descaling uses the two 7-second holds, lever sequence, descaling liquid, and subsequent rinse described above.
