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, 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 it, slide it toward you, keeping it level to avoid spilling. Clean with a damp, soapy, lint-free, non-abrasive cloth.

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.

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.

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 the 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 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.

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.

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 using a Keurig® Water Filter, remove and set aside.

STEP 1: Descaling Solution Rinse
Press 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 into the water reservoir. Press the power button to turn the brewer back on.Place a large mug on the drip tray and run a rinsing brew by selecting the hot water button and selecting the largest brew size.

STEP 2: Descaling Rinse & Repeat
Repeat the rinsing brew process until the add water light is illuminated. 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 fill line.Place a large mug on the drip tray 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 brew process until you have completed at least 12 rinsing brews using the largest brew size. 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 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.

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 add water light is illuminated, 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 4, 6, 8, 10, 12oz, and ICED button lights are all on simultaneously, lift the handle and remove the K-Cup® pod (if present in the brewer). Close the handle and place a large mug on the drip tray. Press the power button once. The brewer may dispense hot water.
If 4, 6, 8, 10, 12oz lights all blink simultaneously, contact Customer Service.

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.

Make sure that the power button has been turned on.

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.
For energy savings, your brewer is set to turn off automatically 2 hours after your last brew. You can program your brewer to automatically turn off in 15-minute increments by adjusting the settings.
If the brewer still doesn’t have power, contact Customer Service.

Adjustable Temperature Not Working

The temperature is not adjustable when set to High Altitude mode. When High Altitude mode is enabled, a mountain icon will be displayed on the screen. If you attempt to adjust the temperature, the mountain icon will flash indicating you are in high altitude mode.

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.

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.
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.
