When cleaning your Keurig® brewer, descaling is an essential step in the process. Calcium deposits, often known as scale, may form on the inside of a coffee maker over time. This technique eliminates such deposits. Calcium and scale are not poisonous, but if they are allowed to accumulate in your brewer without being removed, they may reduce its efficiency.
Scale, also known as calcium deposits, may begin to accumulate in your Keurig coffee machine after some time has passed; this is especially the case if the mineral content of your water is quite high. How To Descale Keurig K-Supreme?
Over time, the accumulation of these compounds may have an effect on both the flavor and quality of the drinks you make with brewed coffee. Scale, although not being harmful to humans, may reduce the efficiency of your coffee maker if it is not removed. Because of this, I have always strongly suggested that you descale your brewer at least once every three to six months at the absolute least.
You will need a big ceramic coffee mug (not a paper cup), access to fresh water, and a sink in order to descale either the Keurig K910 (K-Supreme) or the Keurig K920 (K-Supreme Plus) maker. Both of these models may be descaled in the same manner.
Get the Coffee Machine ready for the Descaling Process.
Empty any water that may be present in the tank that houses your water reservoir into the sink. You’ll want to make sure the water reservoir is completely dry. In addition to this, you will want to check to see that the pod holder does not already contain a K-Cup pod. In the event that the reservoir has a charcoal water filter, this component should be removed as well. Finally, on the drip tray of your Keurig, insert a big ceramic cup in which to collect the descaling solution that has been dispensed.
Incorporate the Descaling Solution.
After taking off the top cover of your water tank, you should next pour your chosen descaling solution into the exposed area. You may alternatively use 90 ounces of white vinegar that has not been diluted if you want an option that is less expensive but also less effective.
UPDATE: It seems that some K-Supreme models are very sensitive to the descale solution, which might occasionally result in unanticipated complications during the process of descaling. In this particular scenario, I suggest putting a specialized formulation, such as this manufacturer’s descaling solution, to the test. Because it was designed to function in commercial brewers, which often have more delicate internal components, it is typically gentler on the heating elements as well. As a direct consequence of descaling, I have experienced a significant reduction in the number of problems, such as the power going out. If you do choose to use vinegar or another formulation, be sure to use extreme caution and avoid using an excessive amount at once.
Last but not least, fill the reservoir with water until it is almost completely full, or as the bottle of descaler solution that you are using directs you to do.
Switch the mode to descale now.
Your K-Supreme brewer is different from brewers of previous Keurig models in that it has a specialized “descaling mode,” which you have to set the brewer into before you can descaling it. Other Keurig models did not have this feature.
Make sure that your brewer is plugged in but turned off before attempting to engage the descaling mode. While simultaneously pressing and holding down the 8oz and 12oz buttons, the process will take between three and five seconds.
Once you see the light on a button begin to flash, you need to hit the BREW button once.
To complete descaling,
Your coffee cup made of ceramic ought to start filling up with the solution. Pour the piping hot contents of the cup into a sink after the brewing process is complete. Repeat the previous step, number 3, until the reservoir is almost, but not quite, depleted of its contents. This is essential because you do not want the internal components of the machine to heat up if there is not a sufficient amount of water moving through the brewer.
OPTIONAL: If you have the time, I always recommend letting the brewer sit for a couple of extra minutes while it is still turned on at this point. However, you should not let the brewer sit for more than 5 minutes at a time because the brewer’s auto-shutoff feature may activate and turn the brewer off by itself. My experience has shown that allowing the descaling solution to sink into the interior elements of the appliance and clean them more thoroughly is helpful. This is not required, and if you want to go on to the next step without completing it, it won’t make much of a difference.
Do a final rinsing and cleaning with fresh water.
In the end, pour any descaling solution that is still in the water reservoir tank of your Keurig K910 / K-Supreme or Keurig K920 / K-Supreme Plus brewer into the sink. This may be done with any model. Next, add clean water to the reservoir until it reaches the MAX line all the way to the top. Brew the water into the ceramic cup, and then drain it into the sink, repeating this process until the water tank is almost empty but not quite dry, or until the “ADD WATER” light comes on.
VERY IMPORTANT: You need to keep doing this step over and over again until the “DESCALE NOW” warning goes away. If you continue to see this warning, it indicates that your coffee machine is still stuck in the “Descale Mode,” which is a situation that may be pretty frustrating when it occurs.
After I descaled my Keurig brewer, I tried to turn it on, but it wouldn’t. What should we do now?
This is an unusual problem that I have seen on occasion, notably in some of the early versions of the K-Supreme (K910) and K-Supreme Plus (K920) models. In particular, I have observed this problem in the K910 model. If you have tried all of the troubleshooting methods, but the device is still not turning on, there may be a problem with the physical thermal switch that powers the in-line heater that is located within the machine. It would seem that some brewers are more likely than others to experience the “tripping” of this switch during the descaling process. This is particularly the case if the brewing process was started before there was sufficient water in the reservoir. Unfortunately, the only solution to this problem is taking the machine apart and reassembling it. In this particular scenario, you should think about using one of these alternatives instead.
My Keurig K-Supreme (K910) or my Keurig K-Supreme Plus (K920) Brewer is displaying a message that says “DESCALE NOW.” How can I make it go away?
When it is necessary to descale your Keurig brewer, a message that reads “Descale Now” will appear on the screen. Make sure that you descale your coffee maker in line with the methods that were provided above in order to get rid of this notice.
Even when I cleaned the scale off of my Keurig, the brewer is still showing that it needs to be cleaned. What action should I take?
Seeing this notification may be a very aggravating thing, especially if you have just descaled your K-Supreme brewer. It is likely an indication that your coffee machine is still in “Descale Mode,” or that one of the stages outlined above for descaling was not completed in the correct manner. Repeat the previous step, number 5, as many times as necessary until the “DESCALE NOW” warning is no longer shown.

How can I LOWER the temperature setting on a Keurig K supreme?
Put a big cup on the drip tray to catch the liquid. First, ensure that the coffee maker is plugged in and turned off. Next, simultaneously press and hold the 8-ounce and 12-ounce buttons for three seconds in order to activate the Descale Mode. To begin the descaling process, push the brew button when the flashing light appears. When the brew is finished, throw the scalding liquid down the garbage disposal.
Why does my Keurig K supreme constantly saying DESCALE?
The descale light on your Keurig indicates that something is preventing water from flowing through the machine. If the light does not turn off, you will need to investigate the cause of the problem, which might be a faulty piping or a cup that is too large for the machine to accommodate.
How long should you let the vinegar sit in the Keurig before attempting to descale it?
You should definitely give it some time to rest for at least an hour if you can. The scale will be removed from the machine by the acidic vinegar to a greater extent the longer it is allowed to sit. It shouldn’t be allowed to sit for more than three hours at a time. You are free to carry out this whole procedure again, all the way up to this stage, if you so choose.
