What does red-yellow light indicate?

If you are noticing a reddish-yellow or yellowish-green hue emanating from your Nespresso machine then it means that you have to descale your coffee machine. What does descaling mean? You may have noticed that your coffee consists of mainly water. This water, regardless of whether it is tap or filtered, might contain some minerals like calcium and magnesium. If you have noticed white solid deposits near your tap, it might be due to these mineral deposits that make the water hard. If you do not descale or remove these mineral deposits regularly, you might end up clogging your coffee machine.

Cleaning your Nespresso coffee machine might be extremely beneficial to you and your family or friends. A clean Nespresso machine gives you a delicious cup of your chosen coffee capsule flavour. If you do not scale this stainless and smooth Nespresso coffee machine often, then the coffee machine might end up getting clogged and give bitter-tasting coffee with a rancid smell. To avoid bacteria growing on old and stuck coffee grinds, Nespresso recommends cleaning and descaling their coffee machine every 300 brews or three months, whichever comes first.

There might yet be multiple reasons for your Nespresso machine to show half-red or yellow light. Some of them are mentioned in the table given below. If none of the fixes seem to be working even after descaling your coffee machine, you can connect with their customer care.
