The most common reason the descale light won’t turn off is that the descaling cycle isn’t complete. You must run two full water tanks through the machine to finish the descaling cycle. Depending on the model of your Keurig, the descaling cycle can take anywhere from 15 minutes to an hour.

Your Keurig is Overdue for a Descaling

Descaling a Keurig coffee maker is essential for keeping it in good condition.

Over time, minerals and other contaminants can build up and cause your machine to perform less optimally.

The water reservoir is full.

When the Keurig descale light stays on, it is often because the water reservoir is full. This is because the descaling process requires water, and it is the water reservoir that contains the water. If the water reservoir is complete, then the descaling process won’t be able to start, and the light won’t turn off.

1. Run Vinegar Through It Until the Light Turns Off

The first thing you can try is running vinegar through your Keurig until the descale light turns off. All you need to do is fill the water reservoir with white vinegar, run it through your Keurig, and then dump out the vinegar when it’s finished. Do this a few times until the descale light turns off.

If the vinegar trick doesn’t work, you can try using CLR or Lime Away on the inside of your Keurig to get the descale light to turn off.

What Not To Do When Your Keurig Descale Light Won’t Turn Off

The first and most important thing to remember is that you should never use your Keurig if the descale light is on. This is because it indicates that your machine needs to be descaled, and failure to do so can cause damage to the internal components, leading to a shorter lifespan for your Keurig.

The next thing you should not do is to ignore the descale light. You should take the necessary steps to fix the issue as soon as possible. The best way to do this is to run a vinegar or water cycle to clean out your machine. This will remove any mineral deposits, debris, and other contaminants causing the descale light to stay on.

Finally, don’t try to perform any repairs on your own. Attempting to repair it yourself can lead to more costly problems in the long run. If you’re unsure what to do, contact a professional for help.

What Type of Water Should You Use in Your Keurig?

When it comes to Keurig machines, two types of water work best: filtered water, reverse osmosis (RO) water, and distilled water.

Filtered Water

Using filtered water in your Keurig is ideal for most types of water. Filtered water has been treated to remove impurities like chlorine, sediment, and other particles. This helps to improve the taste of your coffee and reduces the chances of a clogged machine.

When using filtered water, you should use an activated carbon filter. This type of filter will remove up to 99% of the impurities found in tap water. Changing your filter regularly is also important to ensure you get the best-tasting coffee possible.

Distilled Water

Distilled water is another option for your Keurig. Distilled water is pure water that has been boiled and condensed into liquid form. This process removes all impurities from the water, making it one of the purest forms of water available.

The downside to distilled water is that it can be slightly more expensive than filtered water. It also may not taste as good as filtered water, which could affect the taste of your coffee.

Reverse osmosis (RO) water

RO water is filtered through a semi-permeable membrane, which removes impurities like chlorine, minerals, and bacteria. As a result, it’s much purer than regular tap water.

Using RO water in your Keurig will improve the taste of your coffee. In addition, it can help reduce the buildup of scale in the machine’s internal components, which can lead to poor-tasting coffee or even machine malfunction. Furthermore, if you use RO water, you won’t have to describe your machine repeatedly.


When it comes to using tap water in your Keurig, it is not recommended. Tap water can contain various chemicals, minerals, and other contaminants that can affect the taste of your coffee or tea. In addition, tap water can sometimes lead to clogs in your coffee maker, which can be a hassle to clean up.

How often should I descale my Keurig?

The frequency of descaling your Keurig depends on how often you use it and how hard your water is. If you use your Keurig daily, you should describe it every three months. If you use it less often, you may be able to wait six months between descaling. You may need to descale your Keurig more frequently if you use very hard water.


Descaling the machine is an important part of the maintenance process, so it’s important to ensure you follow the manual’s instructions. The process typically involves running a cleaning solution through the machine and flushing it out. This helps remove any mineral deposits clogging up the water line and causing the machine to malfunction.

If the descale light is still on after descaling the machine, you may need to check for more serious issues. It’s possible that the descaling process wasn’t done the first time correctly or that there is a more serious issue with the machine. If this is the case, it’s best to contact a professional.

We hope this blog helped you understand why the Keurig descale light won’t turn off and what to do if it happens. If you’re still having trouble with your Keurig machine, contacting a professional is always best.
