The problems you are facing:

It is the basic solution for any device, be it your phone or washing machine, turning off and getting it on do wonders for your machine. The same is the case with Keurig.

2. Overfilled or Too Less Water In Reservoir

Too much or less water in a water reservoir can lead to a dysfunctional carafe. Because machine can get water inside of it or if the water is less so it won’t work with this amount of water.

In the case of overfilled Reservoir, Just take some water out of the machine and try again to start brewing coffee. It will surely start working again without any problem.

In case if there is too less water in the reservoir: get all the water out of the reservoir. Refill it again to the preferred amount of water in the reservoir, and your problem will get resolved.

If your machine is still not working, I have listed down the following reasons that can be the issue and there are solutions to these problems as well. Check it out!

3. Check the Brewing Settings

Sometimes, the issue may not lie with the machine itself but rather with the brewing settings. The Keurig K-Duo offers different brewing options, including single-cup and carafe brewing. If your carafe side is not working or only making half a pot, it’s possible that the brewing settings are not configured correctly.

To check and adjust the brewing settings on your Keurig K-Duo, follow these steps:

  1. Ensure the machine is turned on and ready for use.
  2. Press the “BREW SETTINGS” button on the control panel.
  3. Use the arrow keys to navigate through the available options.
  4. Select the desired brewing setting for the carafe side, such as “Full Pot” or “Half Pot.”
  5. Confirm your selection by pressing the “OK” button.
  6. Try brewing a pot of coffee again to see if the issue is resolved.

4. Water Pumping Issue

If your carafe is not making full pots or not working, this might be linked to the water not being pumped properly to the carafe. Because of food particles or maybe mold is getting tubes clogged that is making your machine stuck every time you need a cup of coffee. It is a common issue that arises in coffee makers, and there is a simple solution to it.

To prevent this issue, follow these steps:

  1. Begin by removing and emptying the water tank. Also, take out the water filter holder.
  2. Flip the reservoir upside down and locate the nozzle with the spring. Use something like the eraser end of a pencil to push the spring a few times.
  3. If the spring moves smoothly, it means that the issue lies with the water line.
  4. Attach the tank back to the machine and fill it with a few inches of water.
  5. Get a Turkey Baster and draw up some water into it.
  6. Directly splash the water from the Baster into the nozzle where the tank connects to the water line. This action will help flush out the water line and nozzle.

Repeat this process multiple times until the water line runs clear.

5. Its Time For Descaling

Now we can come to the next part, which is quite easy, and since you are done with the unclogging part, this is a nice time to descale your machine.

Descaling is highly important for your machine to function. This process eliminates the accumulation of calcium deposits, known as scale, inside the coffee maker over time. Although calcium and scale are not harmful, neglecting them can affect your brewer’s performance.

How to Descale Keurig K-Duo

Here’s a simplified step-by-step guide for descaling your Keurig® brewer:

  1. Power off the Duo and remove the water tank, K-cup pod holder, and water filter (if applicable). Ensure there are no coffee pods inside.
  2. Pour the descaling solution into the empty water tank.
  3. Fill the empty bottle with water and pour it into the reservoir.
  4. Place a large mug on the drip tray.
  5. Power on the machine, press the POD button, select the 12 button, and press brew to initiate a cleansing brew. Discard the liquid into a sink.
  6. Place the carafe on the heating plate, press the CARAFE button, and perform another cleansing brew by selecting the 12 button and pressing the brew button.
  7. Empty the carafe into the sink and turn off the heating plate by pressing and holding the Power button.
  8. Allow the brewer to rest for 30 minutes, during which the descaler will clean the interior of the Duo. Do not power off or unplug your Keurig during this step.
  9. Discard any remaining solution from the tank.
  10. Rinse the tank thoroughly and add fresh water, filling it up to the MAX line.
  11. Place the empty and rinsed carafe on the heating plate. Press the CARAFE button and perform a cleansing brew by selecting the 12 button and pressing brew. Once finished, dispose of the liquid.
  12. Repeat step 11 three more times, refilling the tank with clean water to the MAX fill line each time.
  13. Finally, remove the water tank, fill it to the MAX fill line, place a large mug on the drip tray, press the POD button, select the 12 button, and press brew to perform a cleansing brew. Dispose of the liquid into the sink. Repeat this step three more times.

6. Power Supply Problem

If your Keurig machine is still not working, then it can be a problem with your Keurig K-Duo power supply system and this can be the reason behind your coffee maker not making a full pot or not working.

  • To check the power supply, take a current meter and see whether the volt is being matched to the volt this machine requires (220v).
  • If it is below 220 volts, it needs more power. Make sure you take the wiring into consideration.

7. The Basket Switch

We are coming down the lane of reasons for your Keurig K-duo carafe not working, and we have pretty much covered all the considerations but maybe there is something left. Check your coffee basket. Is it placed properly? Your Keurig’s carafe side is not working may be due to the fact that it does not fit in.

Place some weight to make sure it is pressed properly, and this will surely help you in a functional carafe, and the machine will hopefully give you your favorite coffee.

Tip: you can use stones as well for the weight.
