A Small Mistake Could Affect The Descale Process

With all the new models of Keurig, like the Keurig K-Supreme and Keurig K-Express, you must follow the proper descaling process to put your coffee maker in “descale mode” so that the descale light gets turned off. One small mistake, such as pressing the incorrect button, might disrupt the descaling process.

One simple piece of advice is to always try to descale your coffee maker in your free time because when you do it in your busy schedule, you might make some mistake, such as pressing the incorrect button or any other silly mistake that you could have avoided if you had done it in your free time.

Descale Your Keurig K-Supreme While In Descale Mode

With the older models of Keurig coffee makers, all you had to do was add some vinegar or descale solution to the coffee maker and run some brew, and then the descale light would turn off.

But with the Keurig K-Supreme and other newer models, like the Keurig K-Express, you have to put the machine in descale mode and follow the entire descaling procedure before the light goes off.

The guide to descaling the Keurig K-Supreme came with the original user manual when you bought your machine.

The following is the descaling procedure:

  1. Fill the water tank fully with the descaling solution and water.
  2. Press the 8 and 12oz buttons unless the “K” button blinks and the descale light turns on solidly.
  3. Press the K button three or four times, and you’ll turn on the add water light.
  4. Fill the water tank with new water after cleaning it.
  5. Press the K button 3 to 4 times unless the K-Supreme shuts off.

What Should I Do When The Descaling Light Stays On?

After doing the entire procedure, the descale lights still stay on. This happens in some cases when you make a little mistake while doing the procedure.

Always remember not to remove the water tank or open the lid while the machine is in descale mode. This will cancel the descaling mode, and you will have to do the whole procedure again.

Also, try to avoid touching other buttons than those instructed above because it can also take your machine out of descaling mode.

If any of the tricks don’t work, then the simplest solution is to do the entire descaling process again. But this time, you just need to use water because you have previously descaled your coffee machine.

The Last Thing You Could Try

After many attempts, if your machine does not leave descaling mode yet while going through this same descaling process, the first thing you can do is unplug the machine and wait for four to five minutes before plugging it back in. Doing this can fix your problem.

This trick only works if you have completed the descaling process correctly. If, after doing the process correctly, your machine still shows the descale light on, your coffee machine might be damaged from the inside.

If you have a little doubt that your coffee maker might be damaged from the inside, then you should contact the Keurig customer service department. They should be aware of other solutions.

Final Words

It happens sometimes when you descale your coffee maker and the descale lights are still on even after the descaling process.

This could happen when you make a little mistake during the descaling process, and you can solve this issue by following the steps that we have mentioned above.

If those steps don’t work for you, you can simply contact Keurig customer service. They might have more solutions to this problem.
