What Happens If You Ignore The Light And Do Not Descale Your Nespresso For a While?

Over time, mineral deposits from the water, known as limescale, will build up inside the machine if you ignore the descaling light on your Nespresso Vertuo Plus. This buildup can negatively impact water flow and temperature, leading to longer brewing times, inconsistent coffee extraction, and uneven taste.

Furthermore, the accumulation of limescale may clog internal components like the water pump, heating element, and brewing chamber, resulting in the machine not working properly or even failing to operate.

Regular descaling is crucial for maintaining the machine’s performance and prolonging its lifespan. By ignoring the descaling process, you risk causing permanent damage to the internal components, which may require costly repairs or replacement of the machine.
