Entrance Needle

Lift the brewer handle and locate the entrance needle on the underside of the lid. To clean both holes in the needle, hold the brewer handle in the upward position, and with your other hand, carefully insert a straightened paper clip into both 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 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 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, freshwater, 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 15-20 minutes for the descaling procedure.

STEP 1: Descaling Solution Rinse

Pour the entire bottle of Keurig® Descale Solution into an emptied water reservoir. Then, fill the empty bottle with water and pour it into the water reservoir. Do not insert a K-Cup® pod.
Place a large mug on the drip tray. To activate Descale Mode, begin with the brewer powered off, then press and hold the 8oz and 12oz buttons together for 3 seconds until the DESCALE light turns solid.

When the brew button begins flashing, press the brew button to start the cleansing rinse brew. Pour the hot liquid into the sink. Repeat the cleansing rinse process until the ADD WATER light illuminates.

STEP 2: Rest and Rinse

Empty the water reservoir and refill to the MAX fill line with fresh water.

STEP 3: Fresh Water Rinse

Press the brew button once it begins flashing. Repeat this process until the ADD WATER light illuminates.

The brewer will now exit Descale Mode and will be ready for use!

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 the problem persists, allow the brewer to sit unplugged for at least 30 minutes before continuing with the rinse.
