Descaling Your Coffee Maker; Troubleshooting - Keurig K-Mini Plus Use & Care Manual

Descaling your Coffee Maker

You should descale your coffee maker 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 coffee maker. Scale
is non-toxic but if left unattended can hinder coffee maker
performance. Regularly descaling your coffee maker 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.
STEP 1: Cleansing Rinse
Turn on your coffee maker.
Pour one third (136 ml/4.6 oz) of the Keurig® Descaling
Solution into the water reservoir then add fresh water to the
296 ml/10 oz fill level.
Place a large ceramic mug on the drip tray plate.
Lift and lower the handle but do not add a K-Cup® pod.
Press the brew button.
Once solution is dispensed, pour the contents into the sink.

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 coffee maker entrance needle. Refer to the
Entrance Needle care instructions.
Coffee Maker Will Not Brew
• A minimum of 177 ml/6 oz of water is required to brew. Add
an additional 59 ml/2 oz of water to the reservoir to ensure
the minimum fill level has been met, then press the brew
button. Repeat until the coffee maker begins to dispense.
Brewing a Partial Cup
• Press the power button. Press and hold the brew button
for 5 seconds until all of the water has been dispensed.
Discard the contents into the sink. Press the power button
to restart.
• The exit needle may be clogged. Refer to the Exit Needle
care instructions.
• Clean the K-Cup® Pod Holder, see K-Cup® Pod Holder care
instructions.
• The coffee maker may need to be descaled. If you have
repeated the descale procedure on your coffee maker
two times and it is still only brewing a partial cup, contact
Customer Service.
STEP 2: Internal Tank Soak
Repeat step 1, but when the brew indicator light turns
solid, press the power button as the coffee maker starts
to dispense.
Let the coffee maker stand for at least 30 minutes.
Press and hold the brew button until the solution begins to
dispense. Continue to hold the button until all of the solution
has been dispensed.
Pour the contents of the mug into the sink.
STEP 3: Fresh Water Rinse
Repeat step 1 using 355 ml/12 oz of fresh water only. Do
not add Keurig® Descaling Solution. Repeat this step two
additional times. You may need to perform additional fresh
water rinse cycles if you notice any residual taste.
NOTE: The cleaning action of Keurig® Descaling Solution may result in a "foam" dispensed from the coffee
maker. This is natural, as the solution is reacting with the scale inside. For a coffee maker that is heavily scaled,
the coffee maker 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 coffee maker.
• If there is Keurig® Descaling Solution in the water reservoir, discard the contents, rinse the water reservoir
thoroughly and refill with water.
• Plug the coffee maker back in, power on, and repeat the Step 3 Fresh Water Rinse cycle. The coffee maker
should begin to function normally as the solution is rinsed out and the scale is removed. If problem persists,
allow coffee maker to sit unplugged for at least 30 minutes before continuing with the rinse.
Coffee Maker Does Not Have Power or Shuts Off
• Make sure that the power button has been turned on.
• Plug coffee maker into its own grounded outlet. If the
electric circuit is overloaded with other appliances, your
coffee maker may not function properly. The coffee maker
should be operated on its own circuit, separate from other
appliances.
• For energy savings, the coffee maker automatically turns
off 90 seconds after the last brew. Press the power
button to restart.
• If the coffee maker still doesn't have power, contact
Customer Service.
