In this article, we’ll delve into the meaning behind the Nespresso red and yellow light and provide you with the necessary insights to troubleshoot this problem effectively.

Why do Nespresso Vertuo Red And Yellow Light Appear?

The appearance of the red and yellow light on your Nespresso VertuoPlus button is attributed to a specific issue: scale buildup. Over time, the minerals in the water used to brew your coffee can accumulate inside the machine, leading to scale formation.

This buildup can negatively impact the temperature and taste of your coffee and hinder the flow of water within the machine.

Descaling is necessary to address this issue and restore your machine’s functionality.
