How to Fix Nespresso Vertuo Red and Green Light Issue

Nespresso VertuoPlus has a system of lights to show if they’re working okay. When their button flashes red and green light, it means there’s minerals buildup inside the machine, which can be resolved with a quick descaling process.

Mineral buildup might not seem like a big deal, but it can actually have a significant impact on both the taste and temperature of your coffee, as well as the flow of water through your machine. If left untreated, this buildup can eventually lead to problems with the functionality of your machine.

I’ve seen this issue before, and I’m here to walk you through the steps to get your VertuoPlus back up.

So let’s get started!

How To Fix Red and Green Light on Nespresso VertuoPlus

If you see a flashing half red and green light on your Nespresso Vertuo, you need to descale the machine. This is a normal occurrence, and there is no need to worry. Follow these steps to descale and fix this half red and green light error.

SIDENOTE: Complete each step within 2 minutes of the previous step. If you don’t, the VertuoPlus will exit descaling mode.

  1. First, turn the machine ON by pressing the “Coffee” button.
  2. Open the machine head, eject any capsule, and close it again. 
  3. Turn OFF the machine by pushing the “Lever” down position for 3 seconds.
  4. Remove the capsule holder and empty the pods that are in them. Also, eject the drip tray.
  5. Pour 500 ml water and one descaling unit into a water tank.
  6. Push the “Coffee” button and “Lever” for 3-5 seconds at the same time until the orange lights start flashing.
  7. When the orange light is steady, your machine is in menu mode. To enter the descaling mode, push the “Lever” one time.
  8. Place the container (1L) on the coffee outlet and press the “Coffee” button to start descaling. The orange light will be blinking during the descaling process.
  9. After the tank is empty, the machine will automatically turn off. Discard the solution in the sink and rinse the water tank and refill it with 500 ml of fresh water.
  10. Place the container back under the coffee outlet.
  11. Press the “Coffee” button 3 times in 2 seconds to start the rinsing process. This process takes about 2-3 minutes and stops automatically when it’s done.
  12. The green light will come on when the descaling is finished.
  13. To exit the descaling mode, push the “Lever” and “Coffee” buttons at the same time for 3 seconds. You are done!
  14. Let the machine cool down for 10 minutes before using it again.

What To Do If Red and Green Light Still ON After Descaling?

If you have followed the descaling instructions correctly without interruption, the descale light should auto reset. Sometimes, people make the mistake of waiting longer than two minutes in between descaling steps or not letting the water tank empty completely.

If you’ve answered YES to any of the following questions. Then, you may need to repeat the descaling process one or two more times using the descaling solution.

  • Have you ignored the red and green light for a long time?
  • Does your water have a really hard?

But, if you’ve answered NO to all the questions above, you may just need to reset your Vertuo machine to make sure the descaling process was successful.

After careful analysis, it appears that the Nespresso red and green light issue can be easily resolved with a few simple steps. The most common cause of this error is a buildup of minerals in the internal components of the coffee maker. To fix this problem, all you need to do is run a complete descaling cycle for the machine using the Official Nespresso Descaler. Once you have completed this process, your Nespresso should return to its normal working condition.
