10 main reasons for blinking lights on your Keurig:

Water Reservoir not Seated Correctly:

Keurig lights blinks may be the indication that the water reservoir is not seated properly. This is a common issue and can be easily resolved by removing the reservoir and reseating it firmly in place.


Remove the water reservoir and check if it is properly seated. If not, adjust it correctly and make sure it is firmly in place. The blinking lights should stop once the reservoir is seated properly.

Clogged Needles:

Clogging of needles is another common problem that can lead to Keurig lights blinks.

Over time, the needles that puncture the K-cups can become clogged with coffee grinds, making it difficult for the machine to brew properly.


Turn off the machine and unplug it. Remove the K-cup holder and use a paper clip or a toothpick to clean the needles.

Be careful not to damage the needles while cleaning. Once the needles are clean, reassemble the K-cup holder and restart the machine. The blinking lights should stop.

Mineral Buildup:

If you use hard water in your Keurig, mineral buildup can occur in the machine over time. This buildup can cause clogs and lead to blinking lights on your Keurig.


Fill the reservoir with equal parts white vinegar and water, run the machine, and then run a cycle of plain water to rinse.

The vinegar will dissolve the mineral buildup and clean the machine, which should stop the blinking lights.

Empty Water Reservoir:

If the water reservoir is empty, the machine will not be able to brew and will show blinking lights.


Check the water level and refill the reservoir if necessary. The blinking lights should stop once the water reservoir is filled.

Power Outage or Surges:

If there was a power outage or surge, the Keurig machine may not function properly and show blinking lights.


Unplug the machine and wait for a few seconds. Then, plug it back in and restart the machine. This should reset the machine and stop the blinking lights.

Brew Button is Jammed:

If the brew button is jammed or obstructed, the machine will not be able to start the brewing process.


Unplug the machine and remove the K-cup holder. Check to make sure the brew button is not obstructed. If it is, remove the obstruction and restart the machine. The blinking lights should stop.

Air Bubbles in Water Line:

Air bubbles can form in the water line of the Keurig machine, which can prevent the machine from brewing properly.


Unplug the machine and remove the water reservoir. Tilt the machine to release any trapped air bubbles. Then, reassemble the machine and restart it. The blinking lights should stop.

Debris in the Water Line:

If debris or coffee grounds are clogging the water line, the machine will not be able to function properly and will show blinking lights.


Unplug the machine and remove the water reservoir. Use a paper clip or toothpick to clear out any debris or coffee grounds that may be clogging the water line. Reassemble the machine and restart it.

The blinking lights should stop.

Defective Sensor:

If none of the above solutions work, it is possible that the machine has a defective sensor that is causing the blinking lights.


Contact Keurig customer service for further assistance. They may be able to provide you with a solution or offer a repair or replacement.

K-cups Packed Too Tightly:

If the K-cups are packed too tightly, it can cause the machine to malfunction and show blinking lights. This can occur if you are using reusable K-cups and packing them too tightly.


Use the correct amount of coffee in the reusable K-cup and make sure it is not packed too tightly. If you are using pre-packaged K-cups, try a different brand as some K-cups may be packed more tightly than others.

Once you have adjusted the K-cup, restart the machine. The blinking lights should stop.


What might be the problem if all the lights on my Keurig coffee machine are flashing?

If all the lights on your Keurig coffee machine keep flashing, it might indicate a problem with the water filter or needle. Try cleaning the water filters first, and if that doesn't work, clean the needles.

How can I fix my Keurig if the lights are blinking?

To fix your Keurig if the lights are blinking, you can perform a basic reset by turning off the machine and unplugging it for several minutes before plugging it back in and trying to brew again.

Alternatively, you can remove and reseat the cold water reservoir, perform a water-only brew, or perform multiple water-only brews without pods.

How can I force my Keurig to reboot?

To force your Keurig to reboot, turn the machine off, unplug it for several minutes, then plug it back in and try brewing again.

What are some signs that my Keurig might be dying?

Signs that your Keurig might be reaching the end of its lifespan include the machine either stopping brewing altogether or taking longer than usual to brew a cup.


Keurig blinking lights can be caused by various issues ranging from water filter problems to machine malfunctions. It’s important to properly diagnose the issue.
