1. Faulty Plastic Pieces 

Keurig K-Duos has plastic pieces at its handle for design and safety purposes. But often, they become problematic, as they prevent the pot from closing correctly. When the lid cannot be closed, the brew leaks while pouring, leading to a mess and inconvenience.

The best immediate solution to this problem is to remove the plastic piece from the handle. The lid will close once you remove the plastic, and the carafe will no longer leak. 

2. Ridge in the Spout

The parting line on the spout can become uneven with time or might be like that from the start. This irregular ridge in the spout can be why the K-Duo Carafe leaks every time you pour coffee. 

You can check for this problem by moving your hand over the spout to inspect the bumpy ridge. When you run your fingers over it, you will feel a line on the spout, which mysteriously causes the brew to leak. 

How to Fix this Issue?

This problem is relatively quick and easy to solve. All you need is a nail filer or a sandpaper. Rub it over the spout and sand it down until the surface becomes smooth. Rerun your fingers over the area. You will notice that the ridge is no longer present, implying that the issue is resolved. 

3. Alignment Issues 

Issues related to alignment have nothing to do with the manufacturer. Instead, it is a generic problem that usually arises after a repair or re-alignment. The carafe pours brew in the pot from a certain angle and length. 

When the required criteria are unmet, the space between the carafe and the pot increases. This eventually leads to the leaking issue. Similarly, improper placement of the water reservoir can ignite an identical problem. 

How to Fix this Issue?

To solve this issue, you will first need to check the origin of the problem. If it is the reservoir, you can re-adjust its position within minutes. But if the problem is at the counter, ensure that the space between the filler and the pot is manageable. 

4. Problematic Water Reservoir

Another reason for a leaking carafe is a reservoir with pressure issues. When the tank is not attached correctly, it loses its inner pressure and becomes less watertight. Consequently, the water starts dripping off its edges, which leads to leakage. 

How to Fix this Issue?

The solution to this problem is dismantling the reservoir and checking for the ailment causing the pressure to escape. You can resolve the issue with a screwdriver if the reservoir is not attached correctly. 

However, if the reservoir is damaged, you must replace it. Only after that will the K-Duo stop dripping. Besides, prolonging this problem can be fatal, leading to many other malfunctions.

What to Do If the Problem Is Not Solved?
