Stopping the Brewing Process and Cleansing Brew

If you need to stop the brewing after the process has started, press the Power Button and turn the Brewer ‘OFF’. The flow of coffee or tea will stop and the heating element will shut off and the green light illuminating the Power Button will disappear

Important Tip: After an interrupted brew, your cup may have less coffee or tea. To ensure the desired volume for your next brew, we advise running a cleansing brew with water only before your next brewing cycle.

Maintaining Water Level in the Brewer

The LCD Message Center on your Keurig B-50 will indicate when the water level in the tank is low or if the Water Reservoir has been removed by displaying the message ‘ADD WATER’. Brewing is not possible when the ‘ADD WATER’ indication is flashing.

You have two options to fill the Water Reservoir: 

1. While the Water Reservoir is still attached to the Brewer, lift off the Water Reservoir Lid and pour water directly into it, then replace the Lid. 

2. Alternatively, remove the Water Reservoir by lifting it up and away from the Brewer, then fill it with water. After filling, replace the Lid and place the Water Reservoir back in its base.

IMPORTANT: It is essential not to remove the Water Reservoir while the brewing process is underway.

Brewer Operation Modes and Time Programming

  • Leave it ON all the time (recommended)
  • The Brewer offers the option to stay ON continuously, ensuring it is readily available to brew a fresh cup of gourmet coffee or tea at any moment. If you prefer, you can set the time on the clock, although it is optional. To turn off the Brewer, simply press the Power Button. Although the clock will remain on, brewing will be disabled. When you want to use the Brewer again, press the Power Button to restore power. However, it’s important to note that you’ll need to wait for the water to heat up before the Brewer becomes fully ready to brew.

Cleaning and Maintenance of Keurig B-50

Cleaning External Components

Regular cleaning of the external parts of your Keurig B-50 Brewer is recommended to maintain its performance and appearance.

1. Cleaning the Housing

Never submerge the base unit in water or other liquids. You can clean the Housing and other external components with a soapy, damp, non-abrasive cloth.

2. Cleaning the Drip Tray Assembly

The Drip Tray can accumulate overflow, up to 8 ounces. Periodically inspect and rinse the Drip Tray and Drip Tray Plate. To remove the Drip Tray Assembly, slide it toward you while keeping it level to avoid spilling. Both the Drip Tray and Drip Tray Plate are dishwasher safe.

Cleaning the K-Cup Holder Assembly:

1.Cleaning the Parts

The K-Cup Holder Assembly is dishwasher safe. To remove it from the Brewer, lift the Handle to open the cover. Grasp the outside housing of the K-Cup Holder with your thumbs and the bottom of the Funnel with your fingers. Push the Funnel straight up with your fingertips while holding the housing firmly. To replace the K-Cup Holder Assembly, align it with the slots and press until it snaps into place.

2. Cleaning the Funnel

The Funnel can be removed from the K-Cup Holder by pulling on it until it snaps off. The Funnel is dishwasher safe. To replace it, snap it back onto the K-Cup Holder Assembly.

3. Cleaning the Exit Needle

The Exit Needle is located on the inside bottom of the K-Cup Holder Assembly. If a clog occurs due to coffee grinds, use a paper clip or similar tool to clean it. Insert the paper clip into the Needle to loosen the clog and push it out. Wash the Needle with warm soapy water and rinse thoroughly.

WARNING: The K-Cup Holder contains sharp needles that puncture the K-Cup both above and at the bottom. Exercise caution to avoid injury.

Cleaning the Water Reservoir and Water Reservoir Lid:

The Water Reservoir Lid should be cleaned with a damp, soapy, non-abrasive cloth and should not be put into the dishwasher. The Water Reservoir can be cleaned with soapy water and rinsed thoroughly. It is safe to place the Water Reservoir into the dishwasher for cleaning. Avoid drying the inside of the Water Reservoir with a cloth to prevent lint from remaining.

WARNING: After cleaning, make sure to thoroughly rinse the Water Reservoir to eliminate any traces of cleaners or cleaning solutions, as they may taint the water used in the Brewer

De-Scaling Your Brewer: Maintenance for Optimal Performance

Maintaining Water Quality: The mineral content in water can vary, and depending on your location, calcium deposits or scale may accumulate in your Brewer over time. While scale is not harmful, it can affect the performance of your Brewer if left unattended. To preserve the heating element and internal components in contact with water, it’s essential to regularly de-scale your Brewer. We recommend de-scaling every 6 months for optimal performance, but more frequent de-scaling may be required in areas with higher calcium buildup. The Brewer is equipped with sensors to detect scale buildup, indicated by the De-Scale indicator on the LCD Message Center. When lit, it’s time to de-scale following the procedure described below.

IMPORTANT: Even when the De-scale indicator is illuminated, your Brewer will continue to work. However, it is crucial to de-scale promptly after the indicator lights up to prevent potential damage caused by continued scale buildup. If de-scaling is not performed promptly, the De-Scale indicator will start blinking, indicating the urgency to de-scale immediately to avoid any harm to the Brewer.


Step 1: Gather the Supplies

  1. Ensure you have at least 48 ounces of undiluted white vinegar on hand.
  2. Prepare an empty sink and a ceramic cup (avoid using a paper cup).

Step 2: Empty the Water Reservoir

  1. Remove any water present in the Water Reservoir.

Step 3: Fill and Clean the Brewer

  1. Pour the white vinegar into the Water Reservoir, filling it to the top edge of the clear viewing area.
  2. Place a ceramic cup in the Drip Tray and run a brew cycle. Press the Large Cup Button, but do not use a K-Cup. Pour the contents of the cup into the sink.
  3. Repeat the brew process until the Water Reservoir is empty, emptying the contents of the cup into the sink after each cycle. Remember to open and close the lid between each cycle.
  4. Thoroughly rinse the Water Reservoir and fill it with fresh water.
  5. Let the Brewer stand for 4 hours while it remains turned on.

Step 4: Rinse the Brewer

  1. Ensure the Water Reservoir is filled with fresh water.
  2. Place a ceramic cup on the Drip Tray and run a regular brew cycle. Pour the contents of the cup into the sink.
  3. Repeat the brew process until the Water Reservoir is empty.
  4. If any residual taste remains, perform additional rinse cycles as needed.

IMPORTANT: If the De-scale indicator on the LCD Message Center continues to display after finishing the procedure, you should repeat the de-scaling process outlined above.

Storing and Moving the Brewer: Precautions and Recommendations

Proper Storage and Moving Precautions: To ensure the longevity of your Brewer, it’s essential to empty the Water Reservoir before storing it and select a safe, frost-free environment for storage. Avoid storing the Brewer in extremely cold conditions, as water freezing inside the unit can lead to damage. When you’re ready to use the Brewer after storage, remember to rinse the Water Reservoir with fresh water and perform three cleansing brews to prepare it for brewing again. If you need to move your Brewer to a different location, be sure to turn it off, unplug it, and empty the Water Reservoir for safe transportation.
