Cleaning

1. How often should I clean my brewer?

Regular cleaning keeps your brewer running smoothly. Always be sure to unplug your brewer and allow it to cool before cleaning. Periodically hand-wash the water reservoir and lid, carafe and lid, drip tray, and filter basket with warm soapy water and rinse clean. For detailed brewer cleaning and descale instructions, videos, and the full Use & Care Guide, visit support.keurig.com.

2. How often should I descale my 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 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. For detailed brewer cleaning and descale instructions, videos, and the full Use & Care Guide, visit support.keurig.com.

3. Are any of the removable parts (carafe/lid, water reservoir/lid, drip tray, filter basket) dishwasher safe?

No, all removable parts are hand-wash only.

4. How do I clean...

• 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 accumulate 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. Rinse and clean with a damp, soapy, lint-free, non-abrasive cloth.
• Water Reservoir & Reservoir Lid: The water reservoir lid and water reservoir should be periodically cleaned with a damp, soapy, non-abrasive cloth and rinsed thoroughly. The water reservoir lid and water reservoir should not be put into the dishwasher. Do not dry the inside of the water reservoir with a cloth as lint may remain. Fill the water reservoir with approximately two inches of clean water and agitate (shake) the water reservoir. Empty the water reservoir, fill with clean water, and return it to the brewer. If needed, repeat above procedures. CAUTION: Please rinse the water reservoir thoroughly after cleaning. This will ensure that no cleaners or cleaning solutions remain in this area as they may contaminate the water supply in the brewer.
• K-Cup® Pod Holder Assembly: To remove the K-Cup® pod holder from the brewer, lift the handle and grasp the top of the K-Cup® pod holder and firmly pull upward 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.
• Funnel: The funnel can be removed from the K-Cup® pod holder by pulling on it until it pops off. To replace it, 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 the clog and push it out.
• Entrance Needle: Lift the brewer handle and locate the entrance needle on the underside of the lid. To clean both holes in the needle, hold the brewer handle in the upward position and with your other hand, carefully insert a straightened paper clip into both 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 www.keurig.com/support for video instructions on cleaning the entrance/exit needles.
• Carafe and 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.
• Filter Basket and filter basket drawer: Remove the filter basket from the brewer. Remove and discard any ground coffee. The filter basket should be washed in warm, soapy water and rinsed thoroughly. Dry after use. Periodically the filter basket drawer should be removed and washed in warm soapy water, rinse thoroughly. Dry after use.

Carafe Brewing General Troubleshooting

1. I finished brewing a 12 cup carafe, but there is still water in the water reservoir.

If you fill the water reservoir to the max fill line, you may notice there is a small amount of water left over after brewing a 12 cup carafe; this is normal. The MAX fill line is 63 oz and a 12 cup brew is 60 oz.

2. Why did my brew basket overflow?

Most likely you are using too much coffee. The maximum capacity for regular ground coffee is 15 tablespoons and 12 tablespoons for decaf. Exceeding this amount may cause overflow.

3. Can I microwave the carafe?

No, the stainless steel carafe is not microwavable.

4. Why is my brew not starting?

Make sure your brewer is plugged in and powered on.

5. Why are there grounds in my coffee?

Most likely you are using too much coffee. The maximum capacity for regular ground coffee is 15 tablespoons and 12 tablespoons for decaf. Exceeding this amount may cause overflow.

6. Why does the brew basket drip after the cycle is complete?

When a carafe brew is complete, you may experience a few drips. Keurig® recommends waiting about a minute after the brew cycle is complete to allow the excess liquid in the coffee grounds to drain into the carafe.

7. Why is there sediment in my coffee?

Sediment is normal in a carafe brew. Typically, sediment is due to using finely ground coffee. To reduce the amount of sediment, try using a slightly coarser grind.

8. My Keurig® K-Duo Plus™ Single Serve & Carafe coffee maker will not brew.

• After placing the mesh filter or paper filter in the filter basket, make sure that the drip basket drawer is completely closed.
• If the LCD screen says 'add water', add water to the 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 the brew size lights all blink simultaneously, contact Customer Service.

9. What does it mean if the AUTO button blinks 3 times?

If you try to brew a carafe when Auto-Brew is set up, the AUTO button will blink 3 times to signal AUTO is active. You can only brew a single cup when AUTO is on. If you wish to brew a carafe prior to the AUTO brew, you must turn AUTO off. Press the AUTO button; it will no longer be illuminated, and the clock icon on the LCD screen will no longer be on.

Single Cup Brewing General Troubleshooting

1. 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 and the brew buttons are flashing.
• If the LCD screen says 'add water', add water to the water reservoir. Fill to and not beyond the MAX line. Make sure the water reservoir is seated properly in its base. If the 'add water' icon continues to appear on the screen even after refilling, contact Customer Service.
• If the brew size lights all blink simultaneously, contact Keurig® Customer Service at 1-866-901-BREW (2739).

2. Brewing a Partial Cup

• 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 Keurig® Customer Service at 1-866-901-BREW (2739).

Other Troubleshooting

1. Why doesn't the brew start when I press the brew button?

If you have selected POD or CARAFE, then selected your brew size and pressed the BREW button, and your brew doesn't immediately begin, this means the brewer is most likely heating. During the heating process, the BREW INDICATOR light will slowly pulse. Once the brewer is heated, the BREW INDICATOR light will turn solid and begin to brew.

2. Where is the serial number located?

The serial number can be found on the bottom of the K-Duo™ coffee maker box and on the bottom of the drip tray base of the coffee maker. The number will be in the format: 5200.3100.xxxxxxx.

3. What do I do if my brewer shuts off by itself?

Auto off will shut your brewer off 5 minutes after the last brew. Turn the brewer on by pressing the POWER button. If the power does not turn on, unplug the power cord, plug it back in, and press the POWER button. If that doesn't work, please call Keurig® Customer Service at 1-866-901-BREW (2739).

4. None of the buttons on my brewer are working when pressed. What should I do?

If the buttons are non-responsive, please first attempt to press the POWER button. If this does not work, try unplugging the power cord and plugging it back in (after a short period of time). Then, try pressing the POWER button. If this doesn't work, please call Keurig® Customer Service at 1-866-901-BREW (2739).

5. Where can I find detailed cleaning instructions?

Detailed brewer cleaning instructions can be found in the Use & Care Guide on support.keurig.com. Video instructions on how to clean your brewer can be found at support.keurig.com.

6. Descale instructions

Detailed descale instructions can be found in the Use & Care Guide at support.keurig.com. Video instructions on how to descale your brewer can be found at support.keurig.com.

7. It says 'add water' but there is plenty of water...

• Power unit off then power back on.
• Make sure there is water to the Min fill line.
• Make sure the water reservoir is seated firmly on the brewer.

8. I pressed the BREW button but nothing happened

If you press the BREW button after selecting the brew method and size and it doesn't start brewing immediately, this means the brewer is heating. You can tell the brewer is heating when the BREW INDICATOR light is slowly pulsing, aka “breathing”. If the brewer is heating, you can still press the BREW button, and once it has heated, it will begin to brew automatically.

If the unit has already heated up, the BREW INDICATOR light will blink quickly. If you press the BREW button and nothing happens, power the brewer off, then turn it back on and begin the process again. If it still does not brew, contact Customer Service at 1-866-901-BREW (2739).
