If you own a Nespresso Vertuo Plus coffee machine and have noticed a perplexing half red and half green light on its display, fear not – it’s not an enigmatic code but rather a friendly indicator that your coffee maker requires some attention.
In this comprehensive guide, I’ll walk you through the steps to resolve this light issue while providing essential insights to keep your Nespresso machine in tip-top shape.
Understanding the Half Red Half Green Light Issue
To begin, let’s demystify the purpose of this dual-colored light. When your Nespresso Vertuo Plus displays the half red half green light, it’s signaling the need for a thorough descaling process. Over time, minerals naturally present in the water used to brew your coffee can accumulate within the machine, leading to what’s commonly referred to as “scale” or mineral buildup.
This accumulation can significantly affect both the taste of your coffee and the overall functionality of your Nespresso machine. Therefore, timely descaling is key to ensuring your coffee remains flavorful, and your machine operates efficiently.
Determining the Frequency of Descaling
Cleaning your Nespresso Vertuo Plus is an essential part of its maintenance. The manufacturer recommends performing a descaling procedure every three months or after you’ve brewed around 300 cups of coffee. However, this frequency can vary depending on the mineral content of your tap water.
If you’re uncertain about the hardness of your water, consider using a simple and cost-effective water testing kit to assess its mineral composition. This will help you determine whether you need to descale more or less frequently.
Why Vinegar Isn’t the Solution
While some DIY enthusiasts might suggest using vinegar to descale your coffee machine, it’s essential to proceed with caution. Standard white vinegar typically contains acetic acid at a concentration of 5-8%. While it’s useful for many household cleaning tasks, this type of acid can be overly aggressive when used for descaling coffee machines.
It can potentially harm certain components of your Nespresso machine and, perhaps more importantly, could void your Nespresso warranty. Therefore, it’s advisable to explore safer and more effective alternatives for descaling.
Recommended Descaling Solutions
For the safe and effective descaling of your Nespresso Vertuo Plus or Vertuo Plus Deluxe, consider the following descaling solutions:
1. Official Nespresso Descaling Solution
This solution is specially formulated for use with Nespresso machines. It features lactic acid as the primary cleaning agent, which effectively and gently removes the buildup of mineral deposits inside your coffee maker. Each package typically contains enough solution for two complete descaling sessions, ensuring long-term maintenance.

The Caffenu Eco Descaler offers an affordable yet equally effective descaling option. Like the Nespresso solution, it utilizes lactic acid, ensuring safe and efficient descaling. Each package includes two bottles, providing you with enough solution for four descaling sessions if you adhere to the recommended three-month descaling schedule.
Check At Amazon3. Impresa Coffee Machine Descaler
The Impresa Coffee Machine Descaler is a popular choice known for its compatibility with various coffee machines, including Nespresso models. It employs citric and sulfamic acids, both of which are gentle on metal and aluminum components. A single package contains two bottles, each sufficient for two descaling sessions.

Now that you’ve selected a descaling solution, let’s walk through the process of descaling your Nespresso machine. Your Nespresso Vertuo Plus user manual provides detailed instructions, but here’s a summarized step-by-step guide:
- Turn Off the Machine: Begin by pressing the power button to switch off your Nespresso machine.
- Empty Used Capsules: Open the machine’s lid and remove any used coffee capsules, ensuring the chamber is clear.
- Prepare Descaling Solution: Follow the instructions provided with your chosen descaling kit to prepare the descaling solution. For Nespresso’s official descaling solution, typically, you’ll use one packet with 0.5 liters (approximately 17 fluid ounces) of water. Avoid adding excessive water to maintain the solution’s effectiveness.
- Enter Descaling Mode: While the machine remains powered off, press and hold both the power button and the lever simultaneously for three seconds. The machine will power on, and you should see a steady orange light.
- Initiate Descaling: Within the next two minutes, press the lever down once to initiate the descaling process. You’ll know it’s working when you see a blinking orange light.
- Position a Bowl: Place a sufficiently large bowl or container under the coffee outlet to collect any discharged liquids.
- Commence Descaling: Press the start button to begin the descaling process. The machine will automatically stop once the process is complete and the tank is empty.
- Thorough Rinse: After descaling, empty and rinse both the water tank and the cup support thoroughly. Then, refill the water tank with fresh water and reattach it.
- Rinse Again: Press the start button once more to initiate a rinsing cycle. Ensure the water tank runs dry during this rinse cycle, and avoid stopping it prematurely.
- Exit Descaling Mode: To exit the descaling mode, press and hold both the power button and the lever for three seconds. The light should change to green.
- Allow Drying: Let your Nespresso machine sit undisturbed for approximately 10 minutes to allow it to dry fully before resuming normal use.
Troubleshooting the Red and Green Light
In most cases, following the descaling steps should automatically fix the half red half green light on your Nespresso machine. However, if you encounter any issues or if the light remains unchanged, consider the following troubleshooting tips:
- Time Between Steps: Ensure that you complete each step within the recommended two-minute timeframe. Failing to do so may cause the machine to exit descale mode prematurely.
- Incomplete Tank Emptying: If you accidentally stopped either the descaling or rinse cycle before the water tank was entirely empty, it could result in issues. To rectify this, run another cycle using only water (without descaling solution). Your machine won’t differentiate between the two.
- Considering Additional Descaling: If you’ve been consistently ignoring the descale warning for an extended period or if your tap water is exceptionally hard, additional descaling cycles may be required using the descaling solution to ensure thorough cleaning.
Manually Resetting the Light
If, despite your best efforts, the red and green light remains unchanged, you can attempt a manual reset following these steps:
- Turn Off the Machine: Start by pressing the power button to switch off your Nespresso machine.
- Access Factory Settings Mode: Simultaneously press and hold both the power button and the lever for three seconds. You’ll notice an orange light indicating you’ve entered the Special Functions menu.
- Reset to Factory Settings: Press the lever down three times, confirming the action by pressing the power button.
- Completion of Reset: The orange light will blink rapidly three times before transitioning to a steady green light, signifying that your machine is ready for regular use again.
In Conclusion
Regular maintenance, including descaling, is paramount for preserving your Nespresso Vertuo Plus coffee machine. By adhering to the guidelines outlined in this comprehensive guide, you can ensure that your coffee retains its exceptional flavor, your machine operates at its best, and your warranty remains valid.
Instead of feeling puzzled by the half red half green light, use it as a reminder to savor outstanding coffee brewed by a well-maintained coffee maker.
