Descaling Your Brewer - Keurig K-Duo Plus Use & Care Manual

Caring for your Brewer (continued)
K-Cup® Pod Holder
To remove the K-Cup® pod holder
from the brewer, lift the handle
and grasp the top of the K-Cup®
pod holder with one hand while
pushing up on the bottom of
the K-Cup® pod holder from
underneath with the other until
it releases. After cleaning, align
the K-Cup® pod holder with the
opening using the two front ribs as
a guide and snap into place from
the top.
CAUTION: There are sharp needles that puncture the K-Cup® pod above the K-Cup® pod holder and in the
bottom of the K-Cup® pod holder. To avoid risk of injury, do not put your fingers in the K-Cup® pod holder.
NOTE: Used K-Cup® pod should be removed from the K-Cup® Pod Holder after brewing, or in part with the
daily cleaning routine.

Descaling your Brewer

You should descale your brewer every 3 months. Properly
follow the descaling procedure.
Depending on the mineral content of your water, calcium
deposits or scale may build up in your brewer. Scale is non-
toxic but if left unattended can hinder brewer performance.
Regularly descaling your brewer every 3-6 months helps
maintain the heating element, and other internal parts that
come in contact with water. Calcium deposits may build up
faster, making it necessary to descale more often.
Descaling Procedure
Before you begin, you will need a large ceramic mug, 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. Please allow approximately
75 minutes for the descaling procedure.
Empty the water from the water reservoir. If using a Keurig®
Water Filter, remove and set aside.
STEP 1: Descaling Solution Rinse
Power the brewer off.
Pour the entire bottle of Keurig® Descaling Solution into an
emptied water reservoir. Then, fill the empty bottle with
water and pour into the water reservoir. Do not add any
K-Cup® pods or ground coffee.
Place a large mug on the drip tray, then press the POWER
button. Select POD, then press the 12 button. Press the brew
button to start a single cup rinse brew. Pour the hot liquid
into the sink.
Place the carafe on the drip tray. Press the CARAFE button,
Exit Needle
Remove the pod holder assembly.
Locate the exit needle on the inside
bottom of the K-Cup® pod holder.
Insert a straightened paper clip into
the exit needle to loosen any coffee
grounds.
Entrance Needle
Lift the brewer handle and locate the entrance needle on the
underside of the lid. To clean all three holes in the needle, hold
the brewer handle in the upward position and with your other
hand, carefully insert a straightened paper clip into all three
holes. Gently move it around to loosen any coffee grounds.
Lower the handle completely and run two water-only brew
cycles. Do not insert a K-Cup® pod.
TIP: Refer to support.Keurig.com for video instructions on cleaning the entrance/exit needles.
then select the 12 button and press the brew button to start
a carafe rinse brew. When the brew is complete, pour the hot
liquid into the sink.
STEP 2: Rinse & Rest
Let brewer stand for at least 30 minutes.
After 30 minutes, discard any residual solution from the
water reservoir and rinse thoroughly.
STEP 3: Fresh Water Rinse
Fill the water reservoir with fresh water to the MAX fill line.
Place the carafe on the drip tray. Press the POWER button
and select CARAFE. Then press the 12 button and press the
brew button to start a carafe water brew. When the brew is
complete, pour the hot liquid into the sink.
Fill the water reservoir to the MAX fill line. Repeat the 12-cup
carafe rinse 3 more times for a total of 4 brews.
Refill the water reservoir and place a large mug on the drip
tray. Press the POWER button. Select POD, then press the
12 button. Press the brew button to start a single cup water
brew. Pour the hot liquid into the sink.
Repeat the 12 oz brew process three more times for a total
of 4 brews.
NOTE: The cleaning action of Keurig® Descaling Solution may result in a "foam" dispensed from the brewer. This
is natural, as the solution is reacting with the scale inside. For a brewer that is heavily scaled, the brewer 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 brewer.
• If there is Keurig® Descaling Solution in the water reservoir, discard the contents, rinse the water reservoir
thoroughly and refill with water.
• Plug the brewer back in, power on, and repeat the Step 3 Fresh Water Rinse cycle. The brewer should begin to
function normally as the solution is rinsed out and the scale is removed. If problem persists, allow brewer to sit
unplugged for at least 30 minutes before continuing with the rinse.
