What should you do if your Keurig descale light stays on? This article is going to guide you. Read on and follow the instructions to descale your coffee machine properly.

Keurig is among the leading coffee machines worldwide. However, there is a common issue that these coffee machines encounter that will lead to the descale light staying on. 

Why Is the Descale Light On?

A descale light is a standard feature on coffee machines. When the descale light switches on, it signifies the coffee maker needs cleaning.

The descale light can come on when calcium particles or dirt accumulate on the internal parts of the coffee maker which can block the machine. Often, when this occurs, the machine will stop running.

Packing refillable K-cups too tightly can also cause the descaling light to come on. This will limit the water flow within the unit and might trigger the descaling light to turn on.

In short, the Keurig descale light comes on when something blocks water flow.

So, if the light still stays on, you have to identify what is blocking the flow of water through the machine. Perhaps a bad pipe, a strong buildup, or a cup in your machine that’s too large could be the reason.

What to Do If Keurig Descale Light Stays On

Scale develops as calcium and mineral deposits in the water dry up. Using water with high mineral content in a Keurig can cause this buildup and prevent the machine from working properly.

It affects the taste of your coffee as well. The following are different methods to descale a Keurig.

How Often Should I Descale My Keurig?

In order to prevent mineral deposits or scale buildup in your Keurig Coffee Maker, descale it every 3 to 6 months. Apart from descaling, it is also advisable to keep all other parts of the machine clean.

If you are a coffee lover and use your machines every day to brew a K-cup, then make it a habit to clean it at least once a week.

Regular cleaning of your Keurig will extend its life and ensure you can enjoy fresh-brewed coffee any time of the day.
