How to Turn Off the Descale Light on a Keurig? A Quick Guide

When the Keurig descale light starts flashing on your coffee maker, it’s a signal that your machine needs some attention. Ignoring this indicator can lead to performance issues and affect the taste of your coffee. In this post, we’ll explore what the descale light means and why it turns on.

What is a Keurig Descale Light?

The descale light is a crucial feature on Keurig coffee makers. It’s designed to alert you when it’s time to remove mineral deposits and scale buildup from the internal components of your machine. Over time, these deposits can accumulate and affect the machine’s efficiency and the quality of your coffee. The descale light serves as a reminder to perform this essential maintenance task.

Why Does the Descale Light Turn On?

The descale light activates primarily due to the accumulation of mineral deposits and scale inside your Keurig. These deposits can clog the water lines, heating element, and other crucial components, making it harder for the machine to brew properly. When the Keurig detects a decrease in performance due to scale buildup, it triggers the descale light to alert you.

Mineral buildup occurs because of the minerals present in the water you use to brew coffee. If you have hard water, which contains higher mineral concentrations, scale buildup may happen more quickly. The descale light is a proactive measure to ensure your Keurig continues to function efficiently and your coffee remains delicious.

By understanding the purpose of the descale light and the reasons behind its activation, you can take the necessary steps to address it and keep your Keurig in top-notch condition. In the next sections, we’ll explore how to turn off the descale light and perform the required maintenance.

How to get the descale light off on a keurig?

When that pesky descale light on your Keurig won’t turn off, it’s time to take action. Here’s a step-by-step guide to help you reset or turn off the descale light.

General Steps to Turn Off the Descale Light

  1. Prepare Your Keurig: Make sure your Keurig coffee maker is plugged in and powered on.
  2. Empty the Water Reservoir: Start with an empty water reservoir. Remove any water that may be present.
  3. Reset the Descale Light: The method to reset the descale light varies depending on your Keurig model. Here are two common ways:
    a. Keurig with a Descale Button: If your Keurig features a dedicated descale button, press and hold it for a few seconds until the descale light goes off.
    b. Keurig without a Descale Button: For models without a specific descale button, perform a general reset. Unplug your Keurig, wait a few seconds, and then plug it back in. Check to see if the descale light has turned off. If it hasn’t, proceed to the next step.
  4. Descaling with Solution or Vinegar: Sometimes, the descale light remains stubborn because it’s time for a thorough descaling process. Follow your Keurig model’s instructions to descale using a descaling solution or white vinegar. Descaling helps remove mineral buildup, ensuring your Keurig functions optimally.

Troubleshooting Descale Light Won’t Turn Off After Descaling

At times, despite performing the descaling process, your Keurig still says “descale” after descaling. Let’s troubleshoot this issue and explore solutions to ensure your Keurig operates smoothly:

Issue 1: Incomplete Descaling Process

Solution: Ensure that you followed the descaling process correctly and used the recommended descaling solution or white vinegar. Double-check your steps and repeat the descaling process if necessary.

Issue 2: Residue Buildup

Solution: Residue buildup in the water reservoir, K-Cup holder, or other components can trigger the descale light. Regularly clean and maintain these parts to prevent future issues.

Issue 3: Water Quality

Solution: If you have hard water in your area, mineral deposits can accumulate quickly. Consider using filtered or distilled water in your Keurig to reduce scale buildup.

Issue 4: Internal Component Problems

Solution: If none of the above solutions work and the descale light persists, there may be underlying issues with internal components. It’s best to leave complex repairs to professionals. Contact Keurig’s customer support or a qualified technician to diagnose and resolve any internal problems.

Issue 5: Faulty Sensors

Solution: Sometimes, the descale light may remain on due to faulty sensors. Check the sensors inside the water reservoir and around the machine’s components. Clean them gently with a soft, damp cloth to ensure they are free from any residue or debris. If the problem persists, contact Keurig’s customer support for further assistance.

Issue 6: Software Glitch

Solution: In some cases, a software glitch can cause the descale light to malfunction. To resolve this, perform a factory reset on your Keurig. Instructions for a factory reset can usually be found in your user manual or on Keurig’s official website. After the reset, check if the descale light has turned off.

Issue 7: Outdated Firmware

Solution: Some Keurig models receive firmware updates to address known issues. Check if there are any available updates for your machine on Keurig’s website. Updating the firmware may resolve descale light issues.

Issue 8: Electronic Malfunction

Solution: In rare cases, electronic malfunctions can cause the descale light to stay on. If your Keurig is still under warranty, contact Keurig’s customer support for a repair or replacement. If it’s out of warranty, consider consulting a professional technician for assessment and repair.

  1. Check the Water Level: Make sure that the water reservoir is filled up to the MAX FILL line. If the water level is too low, the coffee maker may not be able to brew properly and the descale light may stay on.
  2. Perform a Hard Reset: Try performing a hard reset on your Keurig coffee maker. Unplug the machine from the power source and remove the water reservoir. Wait for a few minutes and then plug the machine back in. Replace the water reservoir and turn on the machine. This may help to reset the sensors and turn off the descale light.

Regular Maintenance Recommendations

Regular maintenance is key to preventing the descale light from coming on and ensuring your Keurig coffee maker functions optimally. Here are some essential recommendations:

  1. Descaling Frequency: To prevent mineral buildup and keep your coffee maker in top shape, it’s advisable to descale your Keurig regularly. The frequency may vary depending on factors like water hardness and usage. As a general guideline, descaling every 3 to 6 months is recommended. However, in areas with very hard water or for heavy coffee drinkers, more frequent descaling may be necessary.
  2. Routine Cleaning: In addition to descaling, incorporate routine cleaning into your maintenance schedule. Daily tasks like emptying the drip tray and discarding used K-Cups help keep your Keurig clean and ready for brewing.


In a nutshell, addressing the descale light on your Keurig is essential to maintain its performance and enjoy a fresh cup of coffee every time. Whether it’s a quick reset or troubleshooting common issues, these methods can help you turn off the descale light and keep your Keurig in top-notch condition.

Remember to follow the manufacturer’s guidelines and recommendations for descaling to ensure the longevity of your coffee maker. A well-maintained Keurig will continue to brew your favorite beverages for many mornings to come.
