Keurig K-Duo Carafe Side Not Working

If you are getting a full pot of coffee with your Keurig K-Duo, it means the carafe button on your Keurig K-Duo is working as it should.

Sometimes this happens when your Keurig K-Duo carafe side fails to produce a full pot or isn’t working at all. This can be frustrating. So, don’t worry about this issue; if you are reading this article, it means you are in the right place.

We will guide you through this issue with all the possible solutions.

Why Is My Duo’s Carafe Side Not Working or Making A Full Pot?

One of the major reasons that your K-Duo is not giving a full pot is most likely due to the coffee basket switch, which prohibits brewing if the coffee basket is not completely inserted. Putting some weight on the filter guarantees that the switch is pressed. This can be done with some decorative stones. Another reason for this issue could be that the K-Duo tubes are clogged or need to be descaled.

Fix The Coffee Basket Switch

Your K-Duo is not giving a full pot, which is most likely due to the coffee basket switch, which prohibits brewing if the coffee basket is not completely inserted. 

Even if you keep the coffee basket fully placed, moisture and coffee grounds in the basket switch might cause it to operate in an inconsistent manner.

Putting some weight on the filter guarantees that the switch is pressed. This can be done with some decorative stones.

If it still does not work with the additional weight, then the other thing you should attempt is cleaning the whole filter portion of the machine with a moist cloth (particularly the coffee basket switch).

If it’s really beneficial, you may try disconnecting the switch from the main power board. and adding a jumper so the Duo can grip the coffee basket and stay in position.

The Coffee Maker’s Tubes Are Clogged.

Debris of minerals can form in the tubes. This may slow down or block the water flow. Because the coffeemaker cannot allow more water through, you will only receive half a carafe of coffee.

If you clicked the brew button when there wasn’t enough water in the reservoir, an air bubble may have become caught in there.

To remove the air bubbles and clogging from the tube, Initially, half-fill the water tank. Then, using equipment like a turkey baster, suck up some water from the water tank and place it on the tank’s water suction port. While your coffee maker is working to produce a cup, press the brewing button and then firmly spray the water in.

A straw or syringe might be used instead of the turkey baster.

A little spring is located in the suction port of the water tank. With the help of the turkey baster, wiggle the spring several times to ensure that nothing is trapped.

You may alternatively remove the water tank and attach a tube to the water suction port. Check that the tube fits snugly on it. Fill the tube halfway with water and blow through the other end. This should have the same outcome.

Your Keurig K-Duo Needs Descaling

So, now that you’ve cleared the blockage, it’s an appropriate time to run a descale cycle on your K-Duo in order to ensure that it gets rid of all the scales that became loose after you pumped water into the tubes. 

Descaling not only removes the loose scales, but it also removes any additional deposits of minerals that have accumulated and can potentially obstruct water flow. Also, scale build-up can ruin the taste of your coffee and make it more bitter.

To stay away from these issues, Keurig suggests descaling your coffee maker every three months.
