Routine Cleaning of the Brewer

  1. Empty the water reservoir and wipe it clean with a damp cloth. Remove any mineral deposits or residue.
  2. Remove the drip tray and wash it with warm, soapy water. Dry thoroughly before reattaching.
  3. Clean the exterior of the machine with a soft, damp cloth. Avoid abrasive cleaners that could damage the matte finish.
  4. Check the brew head and needle for any clogs or debris. Use a paperclip or the cleaning tool provided in the maintenance kit to clear obstructions.

Descaling Your Keurig K-Mini

Mineral deposits from water can build up inside your Keurig, affecting taste and performance. Descaling every 3-6 months is recommended, especially in areas with hard water.

  1. Pour the descaling solution into the water reservoir according to the instructions on the kit.
  2. Fill the reservoir with water to the max line.
  3. Place a large mug on the drip tray and run a brew cycle without a K-Cup. Repeat until the reservoir is empty.
  4. Let the machine sit for 30 minutes to allow the solution to work on scale buildup.
  5. Rinse the reservoir thoroughly and fill with fresh water. Run multiple brew cycles to clear any residual descaling solution.

Troubleshooting Common Issues

If your Keurig K-Mini isn’t brewing properly, check these common problems:

  • No water brewing: Ensure the water reservoir is filled and properly seated.
  • Slow brewing or weak coffee: Clean the needle and descale the machine.
  • Leaks or drips: Check for blockages or cracks in the water reservoir or drip tray.
  • Strange taste or flavor carry-over: Run a cleaning cycle with rinse pods or perform a full descaling.

Using Reusable Coffee Filters

If you prefer ground coffee over K-Cups, the Keurig My K-Cup® Reusable Coffee Filter is highly recommended. It allows you to brew your favorite ground coffee and is compatible with the Keurig K-Mini. Regular use of a reusable filter can save money and offer more variety in your brew.
