The Simple Fix to Turn Off Your Keurig's Descale Light

5 min read SEP 05, 2023

The descale light in a coffee machine can illuminate for various reasons, and one is the accumulation of calcium or dirt particles that impede the machine's internal components, ultimately leading to a malfunction. Another factor that can trigger the descaling light is when refillable K-cups are used and packed too tightly, causing water flow restriction within the machine.

It is recommended that users descale their coffee machines regularly to remove any mineral buildup and use refillable K-cups with a moderate amount of coffee grounds to ensure proper water flow to prevent such occurrences. Neglecting these maintenance practices can result in the machine breaking down, leading to costly repairs or replacements.

How to Fix It?

It is important to clean/descale the machine every three months to maintain the optimal functionality of your Keurig. If the Keurig descale light has turned on, it is time to perform this essential cleaning process. Fortunately, we have a helpful, in-depth guide on effectively descaling your Keurig and restoring your machine to its prime condition.

The following are the step-by-step instructions to describe your Keurig and eliminate the pesky descale light. Following these instructions will ensure that your Keurig functions at its best.

1. Ensure that your Keurig is turned off and all power sources are disconnected.

2. Locate the water filter and remove it from inside the machine.

3. Once this has been done, it is time to pour in the descaling solution to thoroughly clean out any buildup or debris lingering in the machine.

4. After adding the solution, switch the machine on and place a cup underneath to catch any excess liquid.

5. Pour the mixture down a safe spot, such as a sink.

6. Once the brewing cycle is complete, it is important to rinse the water reservoir to remove any remaining solution.

Although we have provided steps for fixing this issue, there may still be instances where the descale message persists. To address this, further troubleshooting may be required to ensure that your Keurig machine is functioning correctly.

Keurig Duo Descale Light Stays On

The Keurig Duo descale light staying on is a typical issue users face. However, your Keurig Duo can be easy; follow the simple steps. If cleaning the machine does not turn off the descale light, simply press the 8oz and 10oz buttons for 5 seconds, and the light will switch off.

What If Descale Doesn't Work?

If the descaling process for your Keurig machine does not appear to be effective and the descale light remains lit, it is imperative to take further action. A significant amount of scale buildup may obstruct the water flow, impeding the descaling process's effectiveness. In such a case, it is recommended to repeat the process with an additional solution or opt for an even stronger solution, such as vinegar, to descale the machine.

Letting the machine sit for an extended period, up to an hour or two, is pertinent to allow the vinegar solution to dissolve the buildup effectively. In rare cases where the buildup is particularly tenacious, citric acid can be utilized to pierce through even the most stubborn accumulations.

The descale light on a Keurig machine is intended to indicate any blockages affecting the flow of water through the machine. If, despite your best efforts, the descale light remains on, it is essential to thoroughly investigate the cause of the obstruction- such as an obstructed pipe or the use of excessively large cups that could overwhelm the machine's functional capacity. By identifying and addressing the source of the blockage, you can ensure the optimal performance of your Keurig machine and enjoy endless cups of fresh, delicious coffee.

Cleaning The Keurig Exit Needle

If you've ever encountered an issue where your Keurig isn't brewing any coffee, it could be due to a blocked exit needle. This minuscule needle penetrates the bump at the bottom of your K-cup but can sometimes become clogged with coffee grounds or other debris.

Thankfully, resolving this issue is relatively simple. You can dislodge the blockage and clean the needle by inserting a sewing needle or paper clip. It is an important step to remember when descaling your Keurig, as it ensures that your machine is functioning properly and you can brew a fresh cup of coffee without any issues.

How Often Should You Descale My Keurig?

It is recommended that you descale it every three months To ensure that your Keurig always brews a perfect cup of coffee. However, the frequency may vary depending on your usage. If you are a regular user who consumes multiple cups every day, you may have to descale your machine more frequently.

But that's not all. You must also be proactive in changing the water filter every two months and cleaning it to avoid a stale taste in your coffee. Failing to do so may cause the taste to deteriorate, ruining your coffee experience. So, follow these steps diligently to keep your Keurig in excellent condition, ensuring a delightful cup of coffee every time.


A descaling light in your coffee maker is an essential feature that reminds you to frequently clean your machine, making it safer to use. Neglecting regular cleaning can cause a buildup of grime and dirt within the device, leading to the malfunctioning of the coffee maker. Therefore, cleaning your coffee maker thoroughly when the descale light illuminates is crucial.

However, if the light persists even after cleaning, you might need to perform an additional deep cleaning to remove stubborn dirt, preventing the device's proper functioning. Therefore, ensure you prioritize cleaning your coffee maker using the descale light feature to enhance your coffee experience and extend its lifespan.

Doesn’t work for me.. tried pressing any and all buttons with the power off and the descale stays on. I’ve run a cleaning pod through and I have a full stream- no blockages. What gives?!


Tried all the 8oz and 10oz tricks. Also 10 and 12.
It ONLY worked when I did this with the power off! (Not while the descale light is flashing)
Hope this helps!


Make sure power button is turned off while holding the 5 and 10 buttons. This finally worked for me.


I descaled my Keurig machine for the second time. Only 6 months old. Use only filtered water in machine. Descale light would not go off until I held the 10 and 8 oz buttons at the same time for 5 seconds. Tried several remedies and this worked.


Had the same problem like everyone else and did everything right also pushed 10 and 8oz buttons. Didn’t work finely I tried to push 12 and 10 instead and that worked 🙃

I have read the comments below and I have the same problem. The descale light will not turn off after the descaling process is complete. How is this problem resolved.

Linda Rybarczyk

I have descale my keurig several times and the light doesn’t go off!! This is a rather new and I clean it often. Help!!!

Evelyn Woods

Same problem as others. No matter what I do the descale light.stays on

Coffee Drinker

This is stupid, I use purified water and I don’t need to do this. There should be a way to disable this.


Same here. Descale light blinks. Frustrating to say the least. I have black electrical tape and I’m gonna cover it. Problem solved!

Followed manufacturers descale process without success. Then followed Jim’s (April 24, 2024) advice:
“Leave unit plugged in, but turn it OFF, then hold the 8 and 10 oz buttons for 5 seconds, then turn back ON. The light went OFF.”
This worked for me and my coffee unit. Thank you, Jim, for posting these instructions!


I agree with everyone about the descale light. I descaled my K slim at 3 months with no descale light, to be on the safe side. The descale came on about 2 months after. I have descaled again with Keurig solution per instructions and the blinking, irritating light has not and will not go off! When this one kicks the bucket, I will definitely select a different brand..

Descaled the product as required and the descale light never goes off even when I have done everything right and pressed the necessary buttons to turn the light off. Another piece of junk

Last cleaning descale light stayed on. Did the 8 & 10 trick & it worked. Didnt this time. Disgusted.


I just descaled, light didn’t go off by itself. I then did what was suggested, held the 8 and 10 button for 5 seconds and the light went off.
Thank you!


the descale light on my keurig k-supreme will not turn off. i have descaled several (3) times, rinsed with fresh water, clean the pod holder manually (there does not appear to be much debris present, as i use the machine daily and keep it clean.)

i have pressed the 8 oz and 10 oz button for about 1 dozen times over a period of several hours now. to me, this is a machine defect, and something i will keep in mind when purchasing another coffee maker…

i have unplugged the machine, run thru severl descale cycles, light stays on.

any suggestions?


When descaling the coffee machine how much vinegar can I use


Light will NOT go off, no matter what I do. So frustrating.


Clean by Keurig K 25 multiple times with a descaling solution and the light stays on. Any other solutions?


OK, so I use the descaling process with a descaling solution. To get the light to go off leave the unit plugged in but turn it off then hold the 8 and 10 buttons for five seconds then turn back on the light went off

Elaine Baldwin

Cleaning this coffee maker is the most aggravating thing I own!!! I clean it faithfully and no matter how many times I press the 8-10 buttons it doesn’t turn off. I’ve used the Keurig cleaner and vinegar and cleaned all the parts! My next step is to throw it out!! Little things, like the light blinking annoy me to no end

Louise Gross

I just turned off the machine, left it plugged in. Held the 8 and 10 for 5 second. Turn machine back on and the light was off.

I also have a second machine that won’t even turn on. Unplugged it for 30 min. Hoping it would reset…it didn’t .


Thank you so much.. I got tired of this.. Thanks for the help♥️♥️
