Common Questions
20 totalHow do I set up my Keurig K-Duo for the first time?
Remove packing tape and plug the coffee maker into an outlet. Rinse the carafe and place it on the heating plate. Remove the water reservoir, fill it with fresh water to the MAX fill line, and replace it ensuring the lock tabs engage. Press the POWER button, then use the H/M buttons to set the clock and press the blinking brew button to confirm the time. The clock must be set to use Auto Brew functionality. (Page 2)
What is a cleansing brew and how do I run one?
A cleansing brew is an initial rinse cycle that prepares the coffee maker. For single cup: press the POD button, do not insert a K-Cup pod, press the 8 button, then press the brew button. For carafe: press the CARAFE button, press the 8 button, then press the brew button. Do not fill the filter basket with coffee grounds. The initial heating process takes about 4 minutes, and pour the hot water into the sink when complete. (Page 2)
How do I enable High Altitude mode?
Press and hold the POD and CARAFE buttons simultaneously for 3 seconds to enable High Altitude mode. When enabled, a mountain icon will appear on the display screen. This setting ensures your coffee maker works properly at higher altitudes (1,500 metres/5,000 feet). (Page 3)
How often should I descale my coffee maker?
You should descale your coffee maker every 3 months. Properly descaling helps maintain the heating element and other internal parts that come in contact with water. Calcium deposits may build up faster depending on the mineral content of your water, making it necessary to descale more often. (Page 5)
What should I do if my coffee maker won't brew?
Check that the K-Cup pod handle is pushed down securely. If the add water light is illuminated, fill the water reservoir to the MAX fill line and ensure it is seated properly. If all buttons blink simultaneously, contact Customer Service. If the 8, 10, and 12 button lights illuminate solid simultaneously, lift the handle, remove any K-Cup pod, close the handle, place a large mug on the drip tray, press the POD button once, and the coffee maker may dispense hot water and lights will turn off. (Page 6)
What do I do if the descaling solution causes foam or low output?
Foam dispensed from the coffee maker during descaling is natural as the solution reacts with scale inside. If the coffee maker does not fill properly and you see only small or no output followed by air blowing sounds, turn off and unplug the coffee maker. Discard the descaling solution from the water reservoir, rinse thoroughly, refill with water, and repeat the Step 3 Fresh Water Rinse cycle. If the problem persists, allow the coffee maker to sit unplugged for at least 30 minutes before continuing. (Page 5)

Coffee Maker Exterior Keep your Keurig® coffee maker 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 coffee maker in water or other liquids. Drip Tray The drip tray can hold up to 237 ml/8 oz 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 Coffee Maker Regular cleaning keeps your coffee maker running smoothly. Always be sure to turn off and unplug your coffee maker before cleaning. We recommend 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 coffee maker. 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. 12 10 8 6

Carafe & Carafe Lid The Carafe and Carafe Lid should be cleaned after each brew. Rinse and clean with a damp, soapy, lint-free, non-abrasive cloth. Heating Plate Once the heating plate has cooled completely, gently wipe with a clean, damp cloth. Never use rough, abrasive materials or cleansers to clean the heating plate. NOTE: To turn off the heating plate you can either press the power button or press and hold the CARAFE button until the red light is no longer illuminated. Filter Basket Remove the filter basket from the coffee maker. Remove and discard the paper filter and ground coffee. The filter basket should be washed in warm, soapy water and rinsed thoroughly. Dry all parts after use. NOTE: Coffee grounds should be discarded and the filter basket should be rinsed clean after brewing, or in part with the daily cleaning routine.
Caring for your Coffee Maker (continued) You should descale your coffee maker 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 coffee maker. Scale is non-toxic but if left unattended can hinder coffee maker performance. Regularly descaling your coffee maker 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 coffee maker 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 coffee maker 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 355 ml/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 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:
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 coffee maker handle and locate the entrance needle on the underside of the lid. To clean all three holes in the needle, hold the coffee maker 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 keurig.ca 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.
