You turn on your Keurig K-Duo, put a filter in, press the carafe button, and if your Duo works how it should, you get a full pot of coffee.
Sometimes, the carafe side on your Keurig K-Duo does not make a full pot or does not work at all. It can be very annoying when this happens.
In this article, I will tell you all the possible solutions to this problem.
Why Is The Carafe Side On My Duo Not Working Or Making a Full Pot?
Your Keurig Duo not making a full pot is probably caused by the coffee basket switch, which prevents brewing if the coffee basket is not fully in place. Adding some extra weight to the filter ensures the switch is pressed down. A few small decorative stones will do the trick. Other reasons may be that the tubes in the K-Duo are clogged or that the K-Duo needs to be descaled.
Scroll down for an explanation of exactly how to do these things.

Fix The Coffee Basket Switch
Your Keurig Duo not making a full pot is probably caused by the coffee basket switch, which prevents brewing if the coffee basket is not fully in place.
Although you got the coffee basket fully seated, moisture and coffee grounds in the basket switch can cause it to work inconsistently.
Adding some extra weight to the filter ensures the switch is pressed down. A few small decorative stones will do the trick.
If it still doesn’t work with the extra weight, the second thing you want to try is to clean the entire filter section of the machine (especially the coffee basket switch) with a damp cloth.
If you’re a really handy person, you could try to unplug the switch from the main board and add a jumper so the Duo thinks the coffee basket is always seated properly.
The Tubes Inside The Coffee Maker Are Clogged
Mineral deposits can accumulate in the tubes. This can restrict the water flow and even block it. When this is the case, you will only get half a carafe of coffee because the coffeemaker cannot pass more water through.
Or an air bubble can get stuck in there if you had pressed the brew button when there was not enough water in the reservoir.
To get the clogging or air bubble out, first, fill up the water tank halfway. Then grab something like a turkey baster suck up some water out of the water tank and put it on the water suction port in the tank. Press the brewing button and then firmly spray the water in as the coffee maker is trying to brew a cup.
Tip: An alternative to the turkey baster could be a straw or syringe.
In the water tank there is a small spring in the suction port, take the top of the turkey baster and wiggle that spring a few times to make sure nothing is stuck.
You could also remove the water tank and put a tube on the water suction port. Make sure the tube fits nicely on it. Fill the tube with water and blow into it from the other side. This should have the same effect.
Your Keurig K-Duo Needs Descaling
So now that you got the blockage out of the way it’s still a good idea to run a descale cycle with your K-Duo to ensure you get all the scales out that came loose when you pumped water into the tubes.
Descaling doesn’t only get rid of the scales that came loose, it also gets rid of the other build up mineral deposits that can also restrict the water flow. Plus, the scale build-up can also affect the taste of your coffee, it will taste more bitter and there will be no crema.
To prevent these problems, Keurig recommends descaling your coffee maker at least once every 3 months.
I wrote a full guide on how to descale your Keurig K-Duo.
Here is a short version:
- Add a bottle of Keurig descaling solution and add the same amount of water to the tank.
- Put a Large cup on the drip tray. Press the pod button, select the 12 oz cup size, and press the “K” Button.
- Pour the liquid into the sink.
- Press the carafe button, select the 12 oz cup size, and press the “K” button. Press and hold the carafe button to turn off the heating plate.
- Let the K-duo sit for at least 30 minutes.
- After 30 minutes throw the remaining descaling solution in the water tank into the sink and rinse the water tank.
- Fill the water tank to the max and rinse both the carafe and pod side four times with the 12 oz button.
The Carafe Side Is Still Not Working Properly
