Then:

You pop a K-Cup pod in, set your mug on the drip tray, and power on your Keurig, anticipating the smooth deliciousness.

Much to your surprise:

You watch with dismay as all or some indicator lights blink continuously and erratically, and your Keurig refuses to brew.

If your Keurig’s lights are flashing, it is probably a signal that something needs to be repaired or adjusted.

Thankfully:

These repairs are not too technical, and you can easily get them done. To this end, we have compiled some useful suggestions to help you.

Here’s what to do when your Keurig’s indicator lights are flashing.

Keurig Is Flashing Lights

Your Keurig’s indicator lights may be flashing for various reasons, usually signs that something needs fixing. To stop your Keurig’s lights from blinking, unclog the exit needle, readjust the water reservoir and filter, or descale your Keurig. You can also fill the K-Cup and reservoir to their required limits or reset your Keurig.

1. Clean and Unclog Your Keurig’s Exit Needle

Here’s the thing:

If all the lights on your Keurig coffee machine keep flashing erratically, it is likely due to a clogged exit needle. Such a clog occurs due to compounded mineral deposits, coffee grounds, and other debris.

Don’t worry:

This issue has a pretty simple remedy. All you need to do is unclog your Keurig’s exit needle.

Here’s how to go about it:

Straighten one end of a paper clip or needle and use it to dislodge the debris in your Keurig’s exit needle.

Then:

Rinse the K-Cup holder thoroughly and unclog the puncture needle for good measure.

Remember to:

Turn your Keurig off and unplug it before fiddling with the needles to avoid hazards.

Now:

The lights should stop blinking after you’ve completed the cleaning. You can then run a water-only rinse cycle to ensure that your Keurig needles are properly cleaned and unclogged.

2. Drain and Realign the Water Reservoir, Then Readjust and Clean the Water Filter

Potentially:

All the lights on your Keurig coffee maker could flash rapidly because the water filter or reservoir is faulty or mispositioned.

Water will not effectively flow when the filter is defective, or the reservoir is misaligned.

Easy fix:

Drain the water tank and readjust the charcoal or carbon filter if it is mispositioned and replace it if faulty.

Next:

Check for any blockage in the valves at the bottom of the water reservoir and clear it out. Also, check for damage or cracks on the water reservoir.

Then:

Fill the reservoir with clean water and reattach it to the Keurig, ensuring it is properly aligned.

Again:

Ensure that your Keurig is unplugged from the power source before attempting to move the reservoir around.

3. Avoid Overfilling the Reusable K-Cup

Look:

Your Keurig coffee machine might be flashing red lights because you have overfilled your reusable K-Cup with too much coffee grind.

It could also be because you have tamped your coffee too hard, and water cannot seep through.

You see:

The Keurig will interpret it as a clog and start to indicate with the continuous flash of the descaling light.

Obviously:

The solution would be only to fill the K-Cup to the required level, roughly three to five centimeters. Also, it would help if you didn’t tamp the coffee too hard.

After following these tips:

Your Keurig’s red lights should stop flashing incessantly and run a brew like normal.

4. Fill the Water Reservoir to the Max Fill Line

Listen:

If your Keurig is flashing blue lights, it is a sign that the water level in the reservoir is low or empty.

Simple solution:

Refill your Keurig’s water tank with filtered or bottled water to the dotted line that denotes the maximum water level.

Get this:

Your Keurig coffee maker will not brew if the water level is below the requirement.

Alternatively:

If adding water doesn’t stop the flashing blue light, switch the device off and turn it back on again. Your Keurig should be back to normal after this.

5. Descale Your Keurig Coffee Maker

So:

Is the descale light on your Keurig flashing? What does that mean, and how do you stop it from flashing?

As you guessed:

If the descale indicator light is flashing on your Keurig, your device is due for descaling.

Your Keurig is clogged with excess mineral buildup called limescale that needs to be eradicated ASAP!

Grab your descaling solution or vinegar and follow these steps:

Pour a mixture of your Keurig descaling solution or vinegar and water into your reservoir.

Next:

Place a large mug on the drip tray and run a brewing cycle to flush the system.

After the cycle is complete, let the descaling solution sit for a while in the reservoir to break down the limescale.

Then:

Discard the mixture, wash your water tank, fill it with plain water and run several rinse cycles to eliminate leftover debris.

Now:

Once you have completely descaled your Keurig, the lights should shut off immediately.

Note:

For proper maintenance of your Keurig, experts recommend that you descale once every three to six months.

6. Reset Your Keurig Coffee Maker

Fact:

Resetting your Keurig is a reliable troubleshooting hack for most of your Keurig’s issues. It is rudimentary, and you can count on it to work.

So:

If all your Keurig’s indicator lights are blinking erratically, giving your Keurig a hard reset should effectively solve this error.

Now:

To reset your Keurig, turn off and unplug the device from the power source for a few minutes. Remove the water reservoir and set it aside for a while as well.

Then:

Put the reservoir properly back in place, plug your Keurig and switch it on. After this, your machine should be reset to factory settings, and all the lights will stop blinking.
