How To Brew Coffee in Keurig K-Duo Plus Coffee Maker

As I already told you that Keurig K-Duo Plus is a dual coffee maker, so I will tell you how to make coffee in both the ways;

Brew Coffee in Carafe Style

To brew coffee in Carafe style, you will need a few essentials, such as;

If you do not have ground coffee, you can either buy ground coffee directly or use the coffee beans after grinding them in a grinder.

For this you can see the article of best coffee maker with grinder.

By following the steps below, you’ll be able to brew coffee in a carafe style on the Keurig K-Duo Plus;

  • Fill the water reservoir with water
  • Switch on the coffee maker with the help of the power button
  • Press the coffee pot button in the control panel
  • Select the desired size
  • Open the front brewing compartment
  • Place the coffee filter in its filter basket
  • Add ground coffee as needed (one tablespoon equals one cup)
  • Close the compartment
  • Press the K button in the control panel
  • Make sure the carafe is properly placed

That’s how you’ll be able to brew coffee in a carafe style on the Keurig K-Duo Plus.

With its thermal carafe, you can easily pour coffee into your cup.

Brew Coffee in Single Cup

To brew a single cup in a Keurig K-Duo Plus, you’ll need a K-cup coffee pod.

Follow the instructions below to start the brewing process;

  • Make sure that the required water is filled in the water reservoir
  • Press the button of the K cup pod
  • Select the desired cup size
  • Open the upper brewing compartment of the coffee maker
  • Place the K-cup pod
  • Close the compartment lid
  • Press the large K button
  • Make sure the coffee mug is in its proper place

Note:- Keep in mind, you have to place the coffee mug a little behind the place of the carafe because while brewing coffee for a single cup, the coffee comes out from the second one which is slightly behind the carafe style location.

This way you can easily brew a single cup of coffee from the k-cup pod.

How To Program Keurig K-Duo Plus Coffee Maker

You can use the control panel to program the Keurig K-Duo Plus.

First of all, you have to press the Auto button, after which you will start showing the time in the display.

The hours and minutes buttons on the control panel allow you to set the time when you want the automatic brewing process to start.

If you set the time for night, you will be able to see “PM” in the display whereas you will not see “AM” if you set the time for morning.

So make sure that if you are setting the time for morning then “PM” should not be showing in the display.

After setting the time, you have to press the brew button (K button), after which you can choose the size of the cup.

If you are fond of strong coffee, then you can also press the strong button.

Finally you have to program the coffee maker by pressing the brew button.

Note:- In Keurig K-Duo Plus you can program coffee maker only for carafe.

Once programmed, you can check that programming has been completed successfully in the coffee maker with an indication light next to the Auto button.

If for any reason you have to cancel programming, just press the auto button once.

How To Clean Keurig K-Duo Plus Coffee Maker

You can use Keurig’s descaling solution to clean the Keurig K-Duo Plus.

Although some people also use white vinegar, but if you do not want any kind of smell in the coffee after cleaning the coffee maker.

So you should use Keurig’s descaling solution.

I am doing this process of descaling Keurig K-Duo Plus with Keurig’s descaling solution.

You can also use this white vinegar instead.

So, let’s get started;

  • Pour the descaling solution into the water reservoir
  • Fill the same amount of water in the Reservoir
  • Press the K cup button and start the single cup brewing process
  • Make sure there is no k cup in the brewing compartment
  • Similarly, start the carafe style brewing process by selecting the coffee pot button
  • After this leave the coffee maker to cool for 30 minutes
  • After 30 minutes fill the water reservoir completely with fresh water and repeat both the brewing methods 3 to 4 times so that the descaling solution is rinsed out

This way you can descale the Keurig K-Duo Plus coffee maker very easily.

You can do this process every 3 to 6 months.

How To Change Water Reservoir’s Position in Keurig K-Duo Plus

You can attach the water reservoir of the Keurig K-Duo Plus coffee maker in 3 different positions.

However, for this you have to be a little careful.

To change the position, first you have to keep the coffee maker upside down, after which you will see 2 tabs.

Then you have to remove them by pushing them inside.

After which you will also have to remove the water reservoir.

Let me tell you that the water reservoir is not completely removable, due to which be careful while removing it.

Above this you will see a button, by pressing which slide the reservoir outwards, after which it will be removed.

After the water reservoir is removed, lift it up and rotate it and attach it to the side where you want it.
