Keurig K-Supreme and K-Supreme Plus: DESCALE light on
The descale notification: the brewer wants descaling. Keurig also says to descale every 3 months regardless. The light only goes off once the full descaling procedure has been done.

What Keurig says to do
- Pour a whole bottle of Keurig Descaling Solution into the empty reservoir, then a bottle-full of water; no pod; large ceramic mug on the tray.
- With the brewer plugged in and powered off, hold 8oz and 12oz together for 3 seconds to enter Descale Mode (see the next page).
- Allow about 15 to 20 minutes in all.

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