Descaling Required

The brewing frequency and intensity scale the insides of the Keurig K-Duo Carafe so much that it seizes to function at all. This results in a dysfunctional Carafe side of your Keurig K-Duo.

Now, you can brew yourself a nice coffee carafe easily.

Too Much Water

If the water reservoir of the Keurig K-Duo is overfilled with water, the carafe will not work. This is because the machine does not allow the water to pass.
