Before starting maintenance, gather essential supplies: a descaling solution (such as the Keurig Descale Solution or a compatible descaling kit), clean water, a soft cloth, and optionally, a reusable coffee filter like the My K-Cup® Reusable Coffee Filter (asin=B0FN6NKZGT). Ensure your machine is unplugged and cooled down after use. Clear the water reservoir to make cleaning easier, and remove any used K-Cup pods.

Cleaning the External and Water Reservoir
- Wipe down the exterior of your Keurig with a damp, soft cloth to remove dust and coffee splashes.
- Remove the water reservoir and wash it with warm, soapy water. Rinse thoroughly to remove any soap residue.
- Dry all parts with a clean towel and reassemble the machine.
Descaling Your Keurig K-Mini
- Fill the water reservoir with a descaling solution mixed with water or just use the Keurig Descale Solution according to the package instructions.
- Place a large mug on the drip tray to catch the rinse water.
- Run a brew cycle without inserting a K-Cup, allowing the descaling solution to flow through the machine. Repeat until the reservoir is empty.
- Fill the reservoir with fresh water and run several rinse cycles to flush out any remaining descaling solution.
Cleaning the Brew Path and K-Cup Holder
Periodically, remove and clean the K-Cup holder and the brew needle to prevent clogs. Use a soft brush or a toothpick to clear any coffee grounds or mineral deposits. Run hot water through the brew path to wash away residue. This step helps maintain optimal water flow and flavor quality.
Troubleshooting Common Issues
- Weak Coffee or No Water Flow: Check for clogs in the brew needle or K-Cup holder. Clean thoroughly and descale if needed.
- Leaking or Overflow: Ensure the water reservoir is seated correctly and not overfilled. Clean the drip tray and check for cracks.
- Machine Not Turning Off: Use the auto-off feature by setting a timer or unplugging after use. Reset the machine by unplugging and replugging if necessary.
