Descaling Procedure

Note: the full descaling procedure must be completed to turn
off the Descale light.
You will need: a large ceramic mug (414 ml/14 oz minimum),
fresh water, Keurig® Descaling Solution, and access to a sink.
Do not use a paper cup. Ensure that there is no beverage
pod in the K-Cup® pod holder. The descaling procedure takes
approximately 20 minutes.
STEP 1: Prepare the Coffee Maker
Pour the entire bottle of Keurig® Descaling Solution into an
empty water reservoir.
Then, fill the empty bottle with water and pour into the
water reservoir.
Do not insert a recyclable* K-Cup® pod.
Place a large mug on the drip tray.
STEP 2: Descale the Coffee Maker
To activate Descale Mode, begin with the coffee maker
plugged in and powered off, then press and hold the 8 oz and
12 oz buttons together for 3 seconds.
When flashing, press the 12 oz button to start the descaling
*Recyclable in select locations.

Grounds in Your Coffee
Grounds may have gathered in the exit or entrance needles
and can be cleaned using a straightened paper clip or similar
• Clean the exit needle of the K-Cup® pod holder. Refer to the
Exit Needle care instructions.
• Clean the coffee maker entrance needle. Refer to the
Entrance Needle care instructions.
For optimal enjoyment and to limit grounds in your cup
during hot water brews or when transitioning from brewing
a coffee pod to a non-coffee pod (i.e. tea or cocoa), clean the
exit and entrance needle per the instructions provided and
perform 2 cleansing brews.
Coffee Maker Will Not Brew
• The water level must be at the minimum line to brew.
Add an additional 59 ml (2 oz) of water to the reservoir to
ensure the minimum fill level has been met, then press
the size button. Repeat until the coffee maker begins
to dispense.
• Lift up and replace the reservoir to ensure a secure fit on
the base.
Once the brew is complete, pour the hot liquid into the sink.
Continue to brew until the ADD WATER light illuminates.
STEP 3: Fresh Water Rinse
Empty the water reservoir, rinse the tank, and refill to the MAX
fill line with fresh water.
When flashing, press the 12 oz button to start the rinsing
Once the brew is complete, pour the hot liquid into the sink.
Continue to brew 12 oz until the DESCALE notification
turns off.
The coffee maker has now exited Descale Mode and will be
ready for use!
NOTE: The cleaning action of Keurig® Descaling Solution may result in a "foam" dispensed
from the coffee maker. This is natural, as the solution is reacting with the scale inside. For a
coffee maker that is heavily scaled, the coffee maker may not fill properly after the descaler
is added. If this occurs, you may see only a small or no output dispensed, followed by the
sound of air blowing out. If this occurs:
• Turn off and unplug the coffee maker.
• If there is Keurig® Descaling Solution in the water reservoir, discard the contents, rinse
the water reservoir thoroughly, and refill with water.
• Plug the coffee maker back in, power on, and repeat the Step 3 Fresh Water Rinse cycle.
The coffee maker should begin to function normally as the solution is rinsed out and the
scale is removed. If problem persists, allow coffee maker to sit unplugged for at least
30 minutes before continuing with the rinse.
Brewing a Partial Cup
• Power the coffee maker off. Press and hold the 12 oz
button for 5 seconds until water starts dispensing. Then
release and let the water purge. Discard the contents into
the sink. Press the power button to restart.
• The exit needle may be clogged. Refer to the Exit Needle
care instructions.
• Clean the K-Cup® Pod Holder, see K-Cup® Pod Holder care
• The coffee maker may need to be descaled. If you have
repeated the descale procedure on your coffee maker two
times and it is still only brewing a partial cup, contact
Customer Service.
Coffee Maker Does Not Have Power or Shuts Off
• Make sure that the power button has been turned on.
• Plug coffee maker into its own outlet. If the electric circuit
is overloaded with other appliances, your coffee maker may
not function properly. The coffee maker should be operated
on its own circuit, separate from other appliances.
• For energy savings, the coffee maker automatically turns
off 5 minutes after the last brew. Press the power button
to restart.
• If the coffee maker still doesn't have power, contact
Customer Service.
