Keurig K-Duo: POD and CARAFE buttons blinking after you press POWER
The brewer is asking which way you want to brew: a single cup from a pod, or a carafe. Once you pick one, the four brew-size buttons blink for the size.
- Which light
- Cup, drink or strength buttons
- Colour
- Colour not named by the maker
- Steady or flashing
- Flashing or blinking
What Keurig says to do
- Press POD for a single cup or CARAFE for the carafe, then choose the size and press BREW.
- For a single cup, press STRONG before BREW for a bolder cup (single cup only).

The same need shows up as a different light on each machine — which is why a light cannot be read without the machine.
