Why the Keurig Descaling Light Stays On

You’ve likely seen the descaling light on your Keurig stay on for seemingly no reason. While this can be frustrating, it’s important to remember that descaling your Keurig is necessary for its upkeep.

This article will explain what descaling is, why it’s important, and how to describe your Keurig. We’ll also provide tips on preventing the descale light from staying on so that you can enjoy your cup of coffee without any added stress.

What Is Descaling and How It Works

Before you panic and run to Google, let’s take a step back and answer some basic questions. What is descaling, and how does it work? Descaling is removing calcium deposits, lime scale, or other mineral build-ups from the heating element of your Keurig.

This build-up can not only impede brewer function, but it can also be a breeding ground for bacteria. The descaling light staying on means that your Keurig needs to be descaled.

It doesn’t necessarily mean that something is wrong—descaling is an important part of keeping your brewer in good working order. But if you’ve never descaled your Keurig before, or if it’s been a while since you last did so, now is a good time to give it a go.

Reasons Why the Descaling Light Stays On

There are a few reasons why the descaling light might stay on even after you’ve descaled your Keurig. Let’s take a look at some of the most common reasons:

You didn’t use enough descaling solution: When you’re descaling your Keurig, it’s important to use enough descaling solution. If you don’t use enough, it won’t be able to clean all of the calcium and mineral build-ups, and the light will stay on.

• You didn’t rinse all the descaling solutions out: After you descale your Keurig, it’s important to rinse all the descaling solutions. If you don’t, it can cause problems with future brews.

• You need to clean your water reservoir: Over time, the mineral build-up can occur in your water reservoir. This can cause issues with future brews and can also activate the descaling light.

If the light stays on after you’ve followed these instructions, it might be time to call customer service for help.

Tips to Get the Descaling Light to Turn Off

If the descaling light on your Keurig stays on, it’s time to descale your coffee maker. This is a very important step to keep your Keurig running smoothly and produce great-tasting coffee.

But don’t worry, descaling your Keurig is easier than you might think. Here are a few tips to help you get the descaling light to turn off:

  • Use a descaling solution specifically made for Keurigs. Do not use vinegar or any other type of household cleaner.
  • Follow the instructions closely when using the descaling solution. Don’t try to shortcut the process in any way.
  • Run several water cycles through your machine after descaling to flush out any lingering chemicals or residue.

How Often Should I Descale My Keurig?

If your descale light stays on, you must describe your Keurig more often. According to Keurig, you should descale your brewer at least every three to six months, depending on the hardness of your water. You should descale even more often if you have particularly hard water.

It’s also important to note that if you use other cleaning solutions besides Keurig’s Descaling Solution, it could cause damage to the machine. That’s why it’s best to always stick with their solutions—they know their product best!

Keep in mind that if you don’t descale your machine regularly enough, not only can it lead to mineral deposits buildup and affect the taste of your coffee, but it can also cause corrosion and problems with the machine’s internal workings. So yes, regular descaling is important if you want your Keurig to keep running in tip-top shape!

What Type of Vinegar Should I Use to Descale My Keurig?

Another question you might have is which type of vinegar you should use to describe your Keurig. The answer is simple: plain white distilled vinegar.

Avoid using any other type of vinegar, as the acidity levels can vary, and this could cause damage to the Keurig’s components. The same goes for lemon or lime juice—they are too acidic and will likely do more harm than good.

It’s also best to avoid using any descaling solution specifically designed for a coffee machine, as these solutions may contain ingredients that could negatively affect Keurig’s performance.

So, all in all, you can descale your Keurig using plain white distilled vinegar for safer and more reliable results.

Troubleshooting Tips if the Descale Light Still Stays On

If, after completing the descaling process, you find that the descale light on your Keurig is still illuminated, there are a few troubleshooting tips to try.

First, ensure that the entire descaling solution has been flushed from the system. This is done by running at least four full-size carafes of plain water through the machine.

If that doesn’t work, another option is to wipe down any visible surfaces with a damp cloth and vinegar solution. This helps loosen any stubborn mineral build-up left behind, causing the descale light to stay on. Finally, if all else fails, we recommend consulting your user manual for specific instructions or contacting Keurig support directly for more help.


The descaling light staying on indicates that it’s time to descale your Keurig. If you’ve been putting it off, now is the time to take care of the problem. Regular descaling will help your Keurig run more smoothly and prolong its lifespan.
