The invention of modern machinery propelled our domestic lives light years into the future. We might not have flying cars or a space colony, but we can dim our bedroom lights with a single voice command.
Every craft required years of practice and training up until a few years ago. However, a machine can now accomplish the same task in a fraction of the time it takes a human expert.
While the benefits of a machine are numerous, you can’t ignore certain drawbacks. If you’ve ever owned a car, you know how nerve-wracking the dashboard lights are.
As soon as they start blinking, a sense of impending doom settles within you. Machinery may be far more advanced than humans, but their way of communicating a fault is often primitive.
Summary
The main reason a Keurig K Supreme & Slim descale light stays on and won’t turn off after descaling is that the process hasn’t been completed yet.

I descaled my machine, and the light won’t turn off
Not every seed you sow will bear you a fruitful tree. Sometimes, you don’t get the result you were hoping for. But it can be especially infuriating after you’ve spent hours fixing a machine, only for the error to reappear.
If you read an instruction manual and follow each line to the dot, the descale light should turn off. But if that’s not the case, you may miss something. Here are all the possible solutions:
- Message not received
- The descaling process hasn’t been completed.
Message not received
After you’ve descaled your machine, you’re also supposed to communicate the same. It can’t detect the removal of calcium deposits by itself. So you hold down the 8oz and 10oz buttons simultaneously for about 3 seconds. However, the light may stay on even after that. In this case, you must press down the buttons for 5 seconds.
The process hasn’t been completed.
The buildup might be too tough even after you’ve spent multiple hours scrubbing the deposits away. To the naked eye, it might seem that most calcium has been removed. But to the machine, the minute deposits remaining might be significant.
Therefore, it’s always best to run a descaling process once more to be sure. All you have to do is pour vinegar into the water reservoir and start the brewing cycle. The method forces the machine to flush the minerals out of the system.
Why does the message pop up?
Before we figure out the ultimate solution, it helps to thoroughly understand the problem at hand. For an avid coffee drinker, descaling might not be a familiar term. But for a coffee machine owner, it’s a highly dreaded word.
A single cup of coffee is made up of 98% water. Only 2% is composed of caffeine, oils, and acids. Surprisingly, the water bit creates a certain waste that requires descaling.
Regardless of your water’s purity, it’s bound to contain some minerals. When you brew a cup of coffee, the water molecules are used up in the process.
However, the minerals and any other compounds remain in the coffee maker. Typically, calcium and magnesium are the biggest contributors to the waste created.
The problem might not become apparent immediately. But after you’ve brewed enough cups of coffee, the waste builds up. Consequently, the descaling light on your Keurig turns on.
How to turn off & reset
Your Keurig brewer must have come with an instructions manual. But often, reading these technical manuals requires another manual. So to make things simpler for you. Here’s what you need to do when the descale light turns on.
Before you look for ways to turn the light off manually, you must have descaled the machine. Because even if you can temporarily switch off the morning, it might turn right back on.
So after you’ve descaled thoroughly and are satisfied with your cleaning abilities, head over to your Keurig duo. If you hold down the 8oz and 10oz buttons simultaneously for about 3 seconds, the descale light will likely turn off.
