Caring For Your Brewer
Regular cleaning keeps your brewer running smoothly. Always be sure to turn off and unplug your brewer before cleaning.
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, nonabrasive 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 it, 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. If needed, repeat the above procedures. CAUTION: Please rinse the water reservoir thoroughly after cleaning. This will ensure that no cleaning solutions remain in this area as they may contaminate the water supply in the brewer.
Cleaning Entrance Needles
Lift the brewer handle and locate the top entrance needles on the underside of the lid. To clean both holes in the needles, hold the brewer handle in the upward position, and with your other hand, carefully insert a straightened paper clip into the 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. NOTE: You can also use a Brewer Maintenance Accessory tool to clean the entrance needles. Reach out to Customer Service to get a Brewer Maintenance Accessory.
Pod Holder
Lift the handle. Push up while grabbing the sides of the pod holder assembly. Pull away from the brewer. Pull out the pod holder assembly and base. Press the release buttons on both sides of the pod holder assembly. Separate the pod holder from the housing. Clean the pod holder (1), housing (2), and base (3) with a damp, soapy, lint-free, non-abrasive cloth and rinse thoroughly. After all, the pieces are cleaned, reassemble the pod holder assembly by inserting the pod holder back into the housing. Place the base, then the pod holder assembly into the brew head. Lower the handle. CAUTION: Sharp needles. Do not put your fingers in the chamber.
Cleaning the Exit Needle
If a clog arises in the exit needle, push the lever of the pod holder to reveal the exit needle. Use a paper clip or similar tool to loosen the clog. Rinse thoroughly with hot water. After all the pieces are cleaned, place the base and then the pod holder assembly into the brew head. Lower the handle. CAUTION: Sharp needles. Do not put your fingers in the chamber.
Descaling Your Brewer
You should descale your brewer every 3-6 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. You should promptly descale when the touch screen indicates “Time to descale the brewer!”
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 45 minutes for the descaling procedure. Empty the water from the water reservoir. If there is a Keurig® Water Filter, remove it and set it aside.
STEP 1: Descaling Solution Rinse
Press and hold the power button to 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 it into the water reservoir. Press and hold the power button to turn the brewer back on. Place a large mug on the drip tray and run a cleansing brew by lifting and lowering the handle, selecting the largest brew size, and pressing the brew button.
STEP 2: Descaling Rinse & Repeat
Repeat the rinsing brew process until the touch screen indicates “More Water Please”. Do not use a K-Cup® pod. Let the brewer stand for at least 30 minutes while still on. 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 and not beyond the MAX line. Place a large mug on the drip tray plate and run a rinsing brew using the largest brew size. Do not use a K-Cup® pod. Pour the contents of the mug into the sink. Repeat the brewing process until you have completed at least 12 rinsing brews. You may need to refill the water reservoir at least one time during this process.
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 it with water.
- Plug the brewer back in, power it 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 the problem persists, allow the brewer to sit unplugged for at least 30 minutes before continuing with the rinse.
NOTE: If the “Time to descale the brewer!” alert is still indicated on the touch screen, repeat the descaling procedure.
Troubleshooting
Brewer Does Not Have Power or Shuts Off
- Press and hold the power button and ensure the touch screen is illuminated.
- Plug the 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.
- If the brewer still doesn’t have power, contact Customer Service.
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 needles. Refer to the Entrance Needles care instructions.
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 descaling procedure on your brewer two times and it is still only brewing a partial cup, contact Customer Service.
Brewer Will Not Brew
After placing a pod in the pod holder, make sure the handle is lowered completely and the touch screen displays the appropriate brew screen. Follow the brewing instructions. If the touch screen indicates “More Water Please” add water to the water reservoir or make sure the water reservoir is seated properly in its base. If the touch screen indicates “More Water Please” even after refilling, remove the water reservoir and empty the water. Then thoroughly clean the reservoir. Fill the water reservoir to the MAX line, return it to the brewer, and ensure it is seated properly in its base. The pod holder may need to be cleaned or the brewer may need to be descaled. Refer to Caring For Your Brewer for instructions.
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.
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. 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 it.
