Keurig Duo Carafe Side Not Working – Reasons & Solutions:

1. Inaccurate Descaling:

Descaling refers to the cleaning of the Keurig Duo Carafe machine’s inside. When you make beverages regularly, minerals can add up and clog this side of the machine. Therefore, it requires proper cleaning after a certain time limit.

To fix this, open the Carafe’s interior and use a mixture of Vinegar and water to clean all components inside. Try using WD40 in case of any rust. When you are done cleaning, test run the water flow inside the Carafe and Coffee machine to wrap things up.

2. Wrong Settings:

Sometimes, the new Keurig Duo Carafe machines have the wrong settings. The user is responsible for looking after and correcting them using the instructions. 

When the machine is turned on, all its settings get jumbled up. This also happens in the old machines if they are in use for a long time.

To fix this error, reset the machine by pressing and holding its red power button for about 5 seconds. Then, turn off the machine, unplug it, and give it some rest. Now, you would plug it back, turn it on, and again check the results by adding the beverages.

3. Water & Power Instability:

Adding too much water to making coffee simultaneously can also damage the machine’s digital motherboard. Once the water reservoir gets overfilled, it doesn’t allow a proper water flow to the Carafe side. This can be solved by removing the extra water by opening the machine and cleaning its needle for proper brewing actions.

Moreover, an unstable power supply can also burn out your digital board in this Keurig Duo coffee machine. As a result, no current flows to the Carafe side, and it doesn’t work. So, having a proper supply of at least 220V can save you from such issues.
