Brewer Exterior
Keep your Keurig® brewer looking its
best by cleaning the exterior from
time to time. Just clean with a damp,
soapy, lint-free, non-abrasive cloth.
Never immerse the brewer in water or
other liquids.
Drip Tray
The drip tray can hold up to 8 ounces
of overflow and should be emptied
and cleaned occasionally. To remove,
slide it toward you, keeping it level
to avoid spilling. Clean with a damp,
soapy, lint-free, non-abrasive cloth.
Caring For Your Brewer
Regular cleaning keeps your brewer running smoothly. Always be sure to turn off and unplug your brewer before cleaning.
We recommend using a Keurig® Rinse Pod or running a cleansing brew immediately after brewing hot cocoa or other sweetened
pods to keep the needles clean.
CAUTION: Parts are not dishwasher safe.
Water Reservoir & Reservoir Lid
The water reservoir lid and water
reservoir should be cleaned
periodically with a damp, soapy,
non-abrasive cloth. Rinse the
reservoir thoroughly after cleaning.
This will ensure that no cleaning
solutions remain in the area as they
may contaminate the water supply.
After rinsing, fill the reservoir with
clean water and return it to the
brewer. Do not dry the inside of the
water reservoir with a cloth as lint
may remain. The water reservoir lid
and water reservoir should not be
put into the dishwasher.
NOTE: If you are using a water filter inside the water reservoir,
remove it before cleaning. The filter cartridge should be replaced
regularly as needed per filter instructions.

cleaning routine

Caring For Your Brewer (continued)
As part of your preventative maintenance routine, you should
descale your brewer every 3 months (or if you experience low
coffee volume or slower performance). 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 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.
Make sure the carafe is on the heating plate. Press the
CARAFE Button, 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. Press the POWER
button to turn the heating plate off.
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.
Make sure the carafe is on the heating plate. 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, press and hold the CARAFE button to turn off the
heating plate. 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.
Descaling your Brewer
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.
Funnel
The funnel can be removed from the
K-Cup® pod holder by pulling on it until
it pops off. To replace it, orient the
snaps to the indent and just snap it
back onto the K-Cup® pod holder.
Exit Needle
Remove the pod holder assembly
and detach the funnel. 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.

Troubleshooting
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 tool.
• Clean the exit needle of the K-Cup® pod holder. Refer to the
Exit Needle care instructions.
• Clean the brewer entrance needle. Refer to the Entrance
Needle care instructions.
• Carafe brewing - The maximum capacity for regular ground
coffee is 15 tablespoons and 12 tablespoons for decaf.
Exceeding this amount may cause overflow.
Brewer Will Not Brew
• After placing the K-Cup® pod in the K-Cup® pod holder,
make sure that the handle is pushed down securely.
• If the add water light is illuminated, add water to water
reservoir. Fill to and not beyond the MAX fill line. Make sure
the water reservoir is seated properly in its base. If the add
water light continues to be illuminated even after refilling,
contact Customer Service.
• If all of the buttons blink simultaneously, contact Customer
Service.
Brewing a Partial Cup or Carafe
• Make sure there is enough water in the water reservoir to
perform the selected brew size.
• The exit needle may be clogged. Refer to the Exit Needle
care instructions.
• The water reservoir may have been removed during
brewing. Replace the water reservoir and perform a rinsing
brew without a K-Cup® pod.
• The brewer may need to be descaled. If you have repeated
the descale procedure on your brewer two times and it is
still only brewing a partial cup, contact Customer Service.
• The drip stop may be clogged. Remove the filter basket
drawer and filter basket and rinse thoroughly to remove
any grounds in the plunger.
• If you live at a high altitude and experience short carafe
brews, please contact Customer Service.
Brewer Does Not Have Power or Shuts Off
• Make sure that you have pressed the POWER button to
turn the brewer on.
• Plug brewer into its own grounded outlet. If the electric
circuit is overloaded with other appliances, your brewer may
not function properly. The brewer should be operated on its
own circuit, separate from other appliances.
• For energy savings, your brewer is set to turn off
automatically 5 minutes after your last brew.
• If the brewer still doesn’t have power, contact Customer
Service.

LIMITED ONE YEAR WARRANTY
Keurig Green Mountain, Inc. (Keurig) warrants that your brewer will
be free of defects in materials or workmanship under normal home
use for one year from the date of purchase. It is recommended
that you register your brewer on keurig.com/new so that your
purchase information will be stored in our system. Keurig will, at its
option, repair or replace a defective brewer without charge upon its
receipt of proof of the date of purchase. If a replacement brewer is
necessary to service this warranty, the replacement brewer may be
new or reconditioned. If a replacement brewer is sent, a new limited
one year warranty will be applied to the replacement brewer.
This warranty only applies to brewers operated in the United States
and Canada. This warranty gives you specific legal rights, and you
may also have other rights that vary from state to state and, in the
case of Canada, from province to province.
Only the use of Keurig® K-Cup® brand pods and accessories will
guarantee the proper functioning and lifetime of your Keurig®
brewer. Any damage to or malfunction of your brewer resulting
from the use of non-Keurig® pods and accessories may not be
covered by this warranty or may result in a service fee if the damage
or malfunction is determined to be caused by such use.
WHAT IS NOT COVERED BY THE LIMITED WARRANTY?
THIS WARRANTY DOES NOT COVER CONSEQUENTIAL OR
INCIDENTAL DAMAGES SUCH AS PROPERTY DAMAGE AND
DOES NOT COVER INCIDENTAL COSTS AND EXPENSES
RESULTING FROM ANY BREACH OF THIS WARRANTY, EVEN IF
FORESEEABLE. Some states or provinces do not allow the exclusion
or limitations of incidental or consequential damages, so the above
limitation or exclusion may not apply to you depending on the state
or province of purchase.
Nor does this warranty cover damages caused by use of non-Keurig®
pods or accessories, services performed by anyone other than
Keurig or its authorized service providers, use of parts other than
genuine Keurig® parts, or external causes such as abuse, misuse,
inappropriate power supply, or acts of God.
OTHER LIMITATIONS
THIS WARRANTY IS EXCLUSIVE AND IS IN LIEU OF ANY OTHER
EXPRESS WARRANTY, WHETHER WRITTEN OR ORAL. IN
ADDITION, KEURIG HEREBY SPECIFICALLY DISCLAIMS ALL
OTHER WARRANTIES WITH RESPECT TO YOUR K-DUO™ BREWER,
INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY
OR FITNESS FOR ANY PARTICULAR PURPOSE. Some states or
provinces do not allow disclaimers of such implied warranties or
limitations on how long an implied warranty lasts, so the above
limitation may not apply to you depending on the state or the
province of purchase.
HOW DO YOU OBTAIN WARRANTY SERVICE?
Keurig® brewers are high-quality appliances and, with proper care,
are intended to provide years of satisfying performance. However,
should the need arise for warranty servicing, simply call Keurig
Customer Service at our toll free phone number 1.866.901.BREW
(2739). Please do not return your brewer for servicing without first
speaking to Keurig Customer Service to obtain a Return Materials
Authorization (RMA) number. Keurig® brewers returned without an

Warranty
Helpful Hints
Water quality varies greatly. If you notice an undesirable
taste in your beverage (such as chlorine or mineral tastes),
we recommend using bottled or filtered water. Do not use
distilled water. You can also install a Keurig® Water Filter to
help remove water impurities and improve beverage taste.
Carafe Brewing
• The maximum capacity for regular ground coffee is 15
tablespoons and 12 tablespoons for decaf. Exceeding this
amount may cause overflow.
• When inserting a paper filter to the filter basket, make sure
it is properly seated flat.
• If the brewer is not used for a few days, run a full carafe rinse
brew to flush out the internal water.
Service
Beyond these recommended cleaning and maintenance
procedures, this brewer is not user serviceable. For service,
please refer to the Warranty section of this guide.
Storage
Empty the water reservoir before storing or transporting and
take care to ensure that you store your brewer in a safe and
frost free environment. Please be sure to store your brewer
in its upright position to avoid water leakage from the inner
tank. If you store the brewer in a cold environment, you run
the risk of water freezing inside the brewer and causing
damage. When you prepare to use it after storage, we
recommend rinsing the water reservoir with fresh water and
running three rinsing brews without a K-Cup® pod, as well as
running a 12 cup carafe brew with no ground coffee.
If you plan to move your brewer to a different location, turn
the brewer off, unplug it, and empty the water reservoir.
If your brewer has been in an environment below freezing,
please be sure to let it warm to room temperature for at
least 2 hours before using.
CAUTION: Please ensure brewer is powered off and heating plate is cooled to room temperature before
storing.
NOTE: If the brewer needs to be stored for an extended period of time (a few months or more), a full descaling
can be conducted before and after storage to ensure the brewer is in its best condition.
