how to turn off descale light on keurig? Detailed guide

I just can’t imagine my day without a cup of coffee, and Keurig proved to be a miracle for me. Just put a k-cup pod inside the machine and push the button and you get a hot cup of coffee within a minute.

How easy that is! But I am really frustrated when Keurig descaling light stays on and won’t brew. This is more ignoring if the descaling light stays on even after descaling the machine.

Until today Keurig has manufactured more than 100 models featured with some unique built-in features to provide ease to their customers. Although these new Keurig models proved to be miracles to those newbies coffee lovers who don’t have handover brewing experience but unfortunately also proved to be a nightmare for some customers.

So, I have discussed the detailed article on how I fix Keurig descale light stays on even though no water is being dispersed issue and discussed some hacks so you can resolve this issue. Keep reading to learn how!

What causes descale light to appear?

The ultimate solo purpose of descaling light features in most coffee makers is to inform or indicate that your coffee machine is filthy and requires thoroughly cleaning/descaling.

Descaling indicator on your Keurig responds to too much gunk built inside the machine, leading to scaling. Hard water(containing a high concentration of calcium and magnesium) consider the prominent culprit in clogging but other factors too also contribute to descaling indicator lights up like air bubbles, loose coffee grounds, dirt, or other tiny particles.

Keurig doesn’t tell about what’s clogging its inner ward, but you will definitely get a clue in the sense as water flow slows down too much and the brewing process won’t proceed properly.

Limescale (layer of while residues accumulating around the sides) is the most common reason of descale lights turn on, and if you ignored it for a while, these residues get big enough that it affects not only your machine performance efficiency but you need to descale your machine most frequently (around 2-3 times).

In the nutshell, we conclude that your machine descaling indicator stays on when the machine requires cleaning. If the machine becomes extremely dirty, it will stop operating.

How do I reset the descale light on my Keurig?

So the ultimate culprit of descaling light is the usage of hard water which leads to scaling. I also had to go through all these, and I knew the frustration behind it. So, I recommend you choose gentler water in your Keurig to avoid this scaling buildup. Also, avoid using filter water as it creates a mess and lights up the room.

So the descaling light is an indicator that you need to descale the machine. I recommend you to go with Keurig’s recommended descaling solution, or you can also go with citric acid and Vinegar solution.

How to turn off the descale light on Keurig?

To get Keurig to descale light off, you need to put Keurig in descaling mode. Keurig supreme series and Keurig slim series are models which come with descale mode.

Follow these steps to turn off the descaling light on Keurig.

  1. Unplug the machine, and drain any water left in the reservoir.
  2. Take the water filter and coffee pods out of the machine.
  3. Place coffee mug underneath the coffee outlet to catch water or descaling solution.
  4. Hold down the 8-ounce & 12-ounce buttons on the Keurig machine for almost three seconds to activate the Descale Mode. The machine will turn on, and the brew button should start to flash. If descale light starts blinking, it should turn solid.
  5. Put Keurig descaling solution inside the machine.
  6. Even if you’ve descaled your machine recently, you’ll need to brew through two full reservoirs of water before the lights turn off. Fill your reservoir half with water, then push the flashing brew button.
  7. Continue to run brews until the light indicator blinks, indicating that the machine requires water. Fill the reservoir again, and then repeat the previous steps until the ‘ADD WATER‘ light illuminates for the second time.
  8. After cycling through reservoirs, your Keurig should exit Descale Mode and the light should turn off.

What to do if the Keurig descaling light won’t turn off?

Gunk buildup inside the Keurig is not only the reason behind the descaling light staying on, there are many other reasons behind the Keurig descaling light won’t turn off or keep coming.

Clogged needle.

A clogged needle is one of the most prominent reasons Keurig descaling light stays on. While using the Keurig coffee machine, there are two needles present- the entrance needle (present under the brewer’s head) and exist needle (bottom of the pod holder). These needles make holes to allow easy flow of water through K-cup pods and make its way to a cup of coffee.

Make sure that the entrance and existing needles are not clogged up. If they are clogged then you need to clean the clogged needle.

1)Cleaning the clogged needles of the Keurig coffee machine

Cleaning entrance needle

  • Unplug the machine
  • Open the brewer handle, you can see the entrance needle under the brewer handle.
  • It has two small holes. Make sure to unclog both of them. You can use a safety pin, a needle, or a straightened paper clip.

Cleaning Keurig existing needle

Exist needle clogged up due to coffee ground or gunk that gets sick to needle making brewing process difficult and also due to this buildup, Keurig stop pumping water.

Follow this procedure to clean the exit needle.

  • Remove the pod holder and the funnel from the bottom
  • A tube is the present underside of the pod holder.
  • Clear off any clogs in the tube with a paper clip, safety pin, or needle.
  • Rinse the pod holder and funnel with tap water to remove any loose particles.

2)Tightly packed pods

I encounter this problem while using refillable coffee pods, obliviously buying new k-cup pods cost me much (recommended to buy budget-friendly k-cup pods). Packing too much coffee in pods makes it difficult for water to pass through, which ultimately triggers Descaler alert.

I resolve this problem by packing the pods loosely. I suggest you if you’re using refillable coffee pods, don’ts fill them all the way to the brim, and never pack the coffee grounds down so you can fit more in.

If you think your problem is due to tightly packed pods, try taking out the pod to check if your machine lets you run a pod-less brew cycle.

3)Plugged tubes

If the problem is something else, then you might have some stubborn air bubbles or dirt particles caught inside of your Keurig. You may push them out by lightly slapping your machine.

If you encounter this problem, follow this procedure

  • Remove the reservoir, drip tray, filter, and any coffee pods from the machine.
  • Hold your Keurig over your kitchen sink and smash it on the side and base a few times.
  • This little Keurig-quake should release anything that has become lodged in the tubes.
  • Finally, perform a brew cycle with clean water to clear up whatever was clogging your water flow.

What to do if the Keurig descaling light is still on after descaling?

The Keurig descale light indicates that something is blocking the water flow, so if the light stays on, you should identify what is blocking the water flow through the machine, which might be faulty piping or a cup that is too large for your machine.

How to prevent descaling light to come up again?

If you are using tap water for brewing coffee, then it is normal for lime scale and other particles to slowly build up inside the Keurig leading to scaling.

So in order to avoid it, I recommend you to use gentler water for Keurig or use a water filtration unit on your tap, but you need to descale your machine after 3-6 months.


Descaling alert is an important feature that reminds you to keep your machine clean and safe to use. But if descaling still didn’t turn off the light, then you might accidentally put your machine on descale mode before it recognizes that you’ve cleaned it.

Make sure to thoroughly clean the machine, don’t pack coffee pods too tightly, use paper clips, and clean the entrance and existing needles to unclog them. Descale your machine once in 3-6 months and using gentler water for Keurig helps in resolving this issue.
