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.


Parts are not dishwasher safe.

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.

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.

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.

Filter Basket & Filter Basket Drawer
Remove the filter basket drawer from the brewer. Remove and discard the paper filter and ground coffee. The filter basket and filter basket drawer 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

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.

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.

Descaling your Brewer

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 nontoxic 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 OZ button to turn on the single cup side. Press the 12 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 CUPS button to turn on the carafe side, then press the 12 button to start a carafe rinse brew. When the brew is complete, pour the hot liquid into the sink. Press and hold the CUPS button to turn off the heating plate.
  • 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 CUPS button to turn on the carafe side, then press the 12 button to start a carafe water brew. When the brew is complete, press and hold the CUPS 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 OZ button to turn on the single cup side, then press the 12 button to start a single cup water brew. 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.

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.

Reinserting the Filter Basket Drawer

To reinsert the filter basket drawer, line up the tab on the filter basket drawer with the rails on the front of the brewer. Insert the tab to the rails and push in firmly until it clicks.
Reinserting the Filter Basket Drawer

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 OZ button or the CUPS 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 60 seconds after your last brew.
  • If the brewer still doesn't have power, contact Customer Service.

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.

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.
