Why Keurig descaling light stays on?

Keurig coffee makers are a staple in many households, providing quick and convenient cups of coffee at the touch of a button. One common problem that Keurig users encounter is Keurig descaling light stays on.

If you’ve ever found yourself staring at your Keurig with a flashing descale light and no idea what to do, fear not!

In this article, we’ll explore some common reasons why the descale light stays on, and what you can do to fix the problem and get your Keurig brewing again.

Why Keurig descaling light stays on?

There are several common reasons why the descale light on a Keurig coffee maker may stay on:

Mineral buildup:

Over time, minerals in the water you use to brew coffee can build up and clog the machine, triggering the descale light.

Clogged water lines:

Similar to mineral buildup, water lines can become clogged with debris and prevent water from flowing properly through the machine.

Faulty sensors:

Occasionally, the descale light may stay on due to faulty sensors within the machine.

Incomplete descaling:

If you’ve recently descaled your Keurig, but the light is still on, it’s possible that the process was not completed properly.

Water quality:

Poor water quality can contribute to mineral buildup and clogged water lines. If you’re using hard water or unfiltered water, it’s more likely that your Keurig will require more frequent descaling.

Machine age:

If your Keurig coffee maker is old or has been used frequently, it may be more prone to issues like the descale light staying on.

Brewing at high altitudes:

If you live at a high altitude, the reduced air pressure can cause water to boil at a lower temperature, which can result in incomplete descaling and trigger the descale light to stay on.

In this case, you may need to descale your Keurig more frequently or use bottled or filtered water instead.

Keurig descaling light stays on: How to fix?

Here are some possible solutions to fix the common issues that may cause the descale light on a Keurig coffee maker to stay on:

Solution for mineral buildup:

To fix this issue, you’ll need to descale your Keurig. This involves running a solution of water and descaling solution through the machine to remove any mineral buildup.

Be sure to follow the instructions in your Keurig’s manual or on the descaling solution package carefully.

Solution for clogged water lines:

To fix this issue, you can try using a paper clip to clean out any debris or buildup from the water lines. Simply straighten a paper clip and insert it into the water nozzle and the exit needle to remove any blockages.

Solution for faulty sensors:

If you suspect that the descale light is staying on due to faulty sensors, you may need to contact Keurig’s customer service for assistance or take the machine to a repair shop for diagnosis and repair.

Solution for incomplete descaling:

If the descale light stays on even after you’ve completed the descaling process, try repeating the process to ensure that all mineral buildup is removed.

You can also try using a more powerful descaling solution or running additional water cycles to flush out any remaining buildup.

Solution for poor water quality:

To prevent mineral buildup and clogged water lines, consider using filtered water or a water softener. This can help prolong the life of your Keurig and reduce the need for frequent descaling.

Solution for machine age:

If your Keurig is old or has been used frequently, it may be time to replace it. Consider purchasing a new machine or having your old one serviced by a professional.

Solution for brewing at high altitudes:

To prevent incomplete descaling at high altitudes, try using bottled or filtered water instead of tap water. You may also need to descale your Keurig more frequently to prevent mineral buildup.


How do I get the descale light off my Keurig?

To get the descale light off your Keurig, you'll need to descale the machine. Follow the instructions in your Keurig's manual or on the descaling solution package carefully to ensure that you complete the process correctly. Once the descaling is complete, the light should turn off.

Why is the descaling light still on after descaling?

If the descaling light is still on after descaling, the machine may not have been rinsed with enough water after using the descaling solution. Try flushing the machine with fresh water to ensure that all the solution is removed.

How do I get my machine out of descaling mode?

To exit descaling mode on a Nespresso machine, press and hold the button and the lever at the same time for 3 seconds, or until the light becomes green. Allow the machine to rest for 10 minutes. The machine is now ready for use.

What to do if the descale light stays on?

If the descale light stays on, it could be due to incomplete descaling, clogged water lines, or faulty sensors. Try repeating the descaling process, using a paper clip to clean out any blockages.


Keeping your Keurig coffee maker well-maintained is crucial for optimal performance and longevity. The descale light is an important indicator that your machine needs cleaning to prevent mineral buildup.

This can impact the flavor and quality of your coffee. If you encounter issues with the descale light staying on, don’t panic.

With proper troubleshooting steps get your Keurig back to normal functioning. And enjoy a fresh cup of coffee in no time.
