But what if your Keurig coffee maker ruins your night by flashing lights instead of brewing coffee? Sometimes all the turn lights are on, and you stand there wondering if your Keurig has broken down.

Keurig can start flashing lights because there could be a problem with the water reservoir; it’s either empty or not correctly attached. Secondly, the charcoal water filter can be missing or loose. Lastly, the most common cause is your Keurig needs descaling and cleaning.

The Keurig Brewer is Dirty

The most frequent issue which causes all lights to turn on is when the coffee maker is dirty. The build-up and gunk can clog the coffee maker’s internal parts, causing brewing problems.

It is the most common reason behind Keurig malfunctioning and flashing lights if you don’t descale and clean it regularly.

The puncturing needles, water tank, K-cup holder, and internal parts of the coffee maker can contain limescale and residue that disrupts normal working.

Solution: Clean your Keurig Coffee Maker.

To clean your coffee maker, make sure you first unplug it.

If you want to clean the puncturing needles, the first step is to open the machine head and remove the K-cup holder. Once you remove the K-cup holder, insert a paper clip into the puncturing needles.

Carefully wiggle around the paper clip to scrap off the coffee residue from the needles. Once done, wash the K-cup holder and the needle under running water to remove any residue.

While cleaning your Keurig, remove its drip tray and water reservoir. Wash them with soapy water and rinse them under fresh water. Next up, dry all the parts with a soft cloth and attach them back to the brewer.

Your Keurig has a Misaligned Charcoal Filter.

The Keurig coffee makers use a charcoal filter to purify water to brew your coffee. The water filter is inside a plastic holder in the water reservoir of your coffee maker.

If the water filter is placed incorrectly inside the water reservoir, it will cause a problem for your coffee maker.

Another thing to remember while using the charcoal filter is that it can become dirty and cause the brewer to malfunction.

Solution: Reposition the Charcoal Filter

Ensure you use the correct water filter handle according to your Keurig model. Use a tall handle water filter if you own a Keurig with a side water reservoir like the K-Supreme, K-Duo, K-Café, K-Slim, etc.

On the other hand, use a short-handle water filter if your brewer has a rear water filter like the K-Compact, K-Latte, K-Duo Essentials, etc.

Once you are sure you use the correct water filter handle, insert the charcoal filter properly. Learn more about installing the water filter correctly.

The charcoal water filter needs replacement every two months or after 60 tank refills to do its job effectively, and your brewer keeps working smoothly.

There is a Hole in the Water Tubing 

If your coffee machine not having sufficient pressure to push water through the coffee, it can be because one of the internal tubes leaks. As a result of the leak, the water will not have enough pressure to pierce through the K-cup and brew coffee for you.

To detect a water tubing leak, you must open your brewer apart and find the leak. Another way of seeing a leak is, hearing weird noises from the brewer during the brewing process,

Solution: Fix or Replace the Water Tubes

If you can handle technical things, unscrew the side of the brewer. Once you remove the sides, you will see the water tubing clearly, so look for any visible leaks.

Once you find the leak, use heat-resistant tape and wrap it tightly around it. Contact Keurig customer service if the problem persists or you are not up for opening your brewer apart. They will repair the leak or replace the water tubing.

Troubleshooting Flashing Lights of Specific Keurig Models 

A Keurig coffee maker’s flashing lights might indicate several reasons. The following are some potential causes in specific Keurig models:

K-Café (Flashing Frothier Light)

K-Café is one of the two models that allow milk in a Keurig, which can sometimes cause trouble. The frothier light can blink for various reasons. Sometimes it is because the whisk is not in the correct position in the frothier, or you need to add more milk. Once you address these problems, the frothing light should cease.

K-Elite (Flashing Clock and Power Buttons)

Keurig’s K-Elite is among the higher-tier models, but it also has its problems. Your K-Elite’s clock and power buttons can start flashing suddenly. To counter this, turn off the machine, unplug it, let it rest, and then power it back on. If the problem persists, you must contact Keurig customer support.

K-Mini Plus and K-15 (Flashing Red Brew Button)

When heating or brewing, the red light from a K-15 or K-Mini Plus blinks. When flashing lights persist for more than three minutes, this may indicate a problem. Keurig customer support is the best place to address your concerns.

Note: If none of these fixes succeeds, there could be a problem with the coffee machine itself. For more help in this situation, it is advisable to contact Keurig customer service.

How long does a Keurig last?

The amount of use and maintenance a Keurig coffee maker receives will determine how long it will last. A Keurig coffee machine should last 2 to 5 years with appropriate usage and care. 

It’s crucial to periodically clean and maintain your Keurig coffee machine to increase its lifespan. Descaling the coffee machine to remove mineral buildup, cleaning the brewer’s exterior, and changing worn-out or broken parts can extend its life.

Operating and maintaining the equipment according to the manufacturer’s recommendations is also crucial. It includes not overloading the device and using just K-Cup pods that are compatible with it.

How to keep your Keurig well-maintained?

The following advice will help you maintain your Keurig coffee maker:

Regularly use a moist towel on your Keurig’s exterior. Clean the Machine’s exterior, paying particular attention to the water reservoir and control panel.

Descale your brewer to remove mineral deposits that may accumulate in the coffee machine and have an impact on its performance. You may use a Keurig descaling solution or a combination of white vinegar and water in equal amounts.

 To learn more about descaling, watch this video, or refer to your brewer’s manual.  

Additionally, you must change the water filter every two to three months. The impurities in the water might alter the flavor of your coffee; thus, the water filter helps to eliminate them. As a result, the water filter gets prone to accumulating bacteria and hazardous substances.

In conclusion, your Keurig machine is one of the most frequently used household coffee makers. It works well for quickly brewing a whole pot or just one cup of coffee. Issues can arise occasionally. In the eventuality that the lights remain on continuously. Three options are available:

  • Your Keurig coffee maker has clogs, or the water has a misaligned water filter.
  • You need to reset your Keurig.
  • Fix a leak in your coffee maker’s tubes.


Where is the reset button on my Keurig?

Unfortunately, there is no reset button on Keurig coffee machines. To reset your brewer, you can simply unplug it, remove its water reservoir, and let it sit for one to two hours. If it doesn’t work, refer to the user manual of your coffee maker.

How do I unfreeze my Keurig?

There are a few methods you may attempt to unfreeze your Keurig coffee maker if it isn’t working correctly. Allow the device to sit for a few hours after unplugging it. If you think the water tubing has frozen, try using a hair dryer or running a hot water brew cycle. Make sure to keep the machine in a dry, indoor place shielded from excessive temperatures to avoid this problem in the future.
