Regularly Descaling your Keurig Supreme coffee maker will keep it from developing a moldy smell and keep your coffee from getting a stale taste.

The Keurig Descale light lets you know when your coffee maker needs cleaning. However, it becomes an issue when the Descale light refuses to go off. So, how do you turn this light off?

To turn off the Descale light on Keurig Supreme when it stays on, hold down the 80-ounce and 10-ounce buttons for five seconds. The light should turn off after. If it does not turn off, there is still dirt on the coffee maker that you might have missed the first time. Do an extra cleaning to get rid of it.

How to Turn Off Descale Light On Keurig Supreme

The Keurig Descale light is a crucial feature of the Keurig Supreme plus coffee maker, which triggers when sediments of calcium, leftover coffee particles, or dust clog the machine up and slow it down.

In addition, packing refillable Keurig cups too tightly can restrict water flow and cause the Descale light to come on.

To get the Descale light to turn off, follow these steps.

#1. Step One

Switch off your Keurig supreme coffee maker and ensure no power is in it. Unplug the brewer as well.

#2. Step Two

Release the contents of the water reservoir as well as that of the water filter in the coffee maker. Remove the water filter.

#3. Step Three

Ready your Descale solution. It could be a commercial descaling solution or a homemade one made with vinegar or citric acid.

Pour it into your Keurig to clean out the scale within. Also, add a filled bottle of fresh water to the water reservoir of your Keurig. 

Avoid using filtered water, as this would cause scales to scratch the inner surfaces of the coffee maker during the Descale process.

Do not use boiling water either. There should be remnants of caffeine in the coffee maker, and caffeine is difficult to dissolve with boiling water.

If you instead use boiling water for the descaling process, let the machine rest for 30 minutes before Descale it.

#4. Step Four

Turn your Keurig back on and place a cup under it.

#5. Step Five

Throw the mixture in the cup into the sink.

#6. Step Six

The Keurig releases more fresh water to repeat the process. Switch on the brewer for 30 minutes.

#7. Step Seven

Rinse the water reservoir properly. To ensure your coffee maker is thoroughly clean, repeat these steps 10-12 times.

After following these steps, the Descale light will remain off when you power your Keurig supreme coffee maker back on.

You can turn off Descale light by resolving issues like clogged needles and plugged tubes which stubbornly keep the Descale light on no matter how hard you Descale your Keurig supreme.

The table below lists the possible causes and the solutions to them.

Clogged FilterUse rinse capsules once a week. Please remove the water filter and clean it under a strong flow of fresh water. Change the water filter every two months to avoid the faint gurgling noise of clogged filters.
Blocked TubesUnplug your Keurig. Remove the reservoir, water filter, tray, and leftover pods inside. Hold the coffee maker over the kitchen sink and firmly slap its base and sides. This action should dislodge stuck objects in the tubes. Finish off by running a brew cycle with fresh water to wash the particles.
Packed PodsRefill your coffee pods more loosely so water can quickly get through. To be sure if your pod is causing the Descale light to stay on, take it out and see if the light goes off.
Clogged NeedlesUnplug the Keurig and lift its handle. The entrance needle will be right under the head. It has two small holes, so use a straightened paper clip or a safety pin to remove the grime clogging it. Next, dislodge the pod holder and remove the funnel from the bottom. There will be a tube poking out from the bottom of the pod holder. Clear the grime from the tube with your safety pin or paper clip. Finally, rinse the pod holder and funnel to clear out leftover particles.

Other problem signs include visible sediments at the bottom of the water reservoir and layers of white residue at the bottom sides of the inner surfaces.

Mineral deposits from water can build up in your Keurig Supreme coffee maker over time, especially if your water is hard.

Eventually, this buildup of mineral residue, also called limescale, can affect the quality of coffee from that coffee maker.

Scale is usually not toxic, but it leaves a bad taste lingering in your coffee and is even capable of causing your coffee maker to break down if left unattended.

It is why Keurig highly recommends Descaling your coffee maker at least every three months.

How to Fix if K-Supreme Plus C Says Descale even After Descaling?

The K-Supreme Plus C has an official Descale mode, which you must activate before the Descaling process; then, the coffee maker recognizes it.

Otherwise, the machine’s computer will keep saying Descale after you have descaled it. To fix it, you must repeat the descaling process but put the coffee maker in Descale mode first.

These steps will guide you on how to carry out the Descale process in descale mode.

#1. Step One

Turn your machine off, and remove its plug from the power outlet.

#2. Step Two

Drain the water in the reservoir and water filter. Afterward, take the water filter and any coffee pods left within.

#3. Step Three

Place a cup under the Keurig where you usually place it. The cup will catch the mixture released during the Descale process.

#4. Step Four

Plug your coffee maker back in, but do not turn it on.

#5. Step Five

Put your Keurig into Descale mode by holding the 8-ounce and 12-ounce buttons simultaneously for 3 seconds.

It will power up your coffee maker, and the brew button will begin to flash. If your Descale light was flashing, the light should turn solid at this point.

#6. Step Six

Your Keurig is now in Descale mode. Since you have already descaled your coffee maker, there is no need to descale it again.

So brew through two full reservoirs of water. To do this, pour water into your reservoir till it’s full and push the flashing brew button. 

Note that if you have not to descale your Keurig for months, you should go through a Descale process with your Keurig Descaling solution after putting your machine on descale mode.

#7. Step Seven

When the cup is full of water, empty it, place it under the coffee maker and push the brew button again.

Repeat this process until a light blinks, which also tells you to pour more water. Then, refill the reservoir and continue running brews.

#8. Step Eight

When you complete two full reservoir cycles, your Keurig should exit Descale mode. Then the Descale light would finally turn off.

Keurig K-Supreme Plus Failure after Descale, Won’t Turn On?

It means the solution you used to Descale your coffee maker is too strong. The Keurig K-Supreme Plus is very sensitive to Descaling solutions.

When you use Descaling solutions that are too harsh for its sensitive internal parts, unexpected issues can arise during or after the Descaling process.

The heating elements may take the brunt of the problem and fail to restart. In addition, the machine may fail to come back on. 

One solution is to change your solution to Descale your Keurig K-Supreme Plus. For example, you can use a Keurig Descaling solution formulated to work in commercial breweries with more sensitive internal parts.


Before storing your Keurig Supreme coffee maker at the bed of the brewing season, clean it thoroughly.

As the most common reason for scaling is sediments and minerals in the water, it would be helpful to use softer water to brew coffee.

The more hard water you use, the more you would have to Descale your Keurig supreme.
