What Keurig says to do
- Wait for the light to go out before lifting the handle or removing the carafe.
- After hot cocoa or other sweetened pods, Keurig recommends a rinse pod or a cleansing brew to keep the needles clean.
From K-Duo Use & Care Guide: Before You Brew, cleansing brews, Brewer Features, Auto Brew, Caring for your carafe and Troubleshooting. This is the K-Duo’s pattern; another Keurig machine may use the same light for something else — check the manual for your model.

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