Routine Cleaning of the Brewer
- Empty the water reservoir and wipe it clean with a damp cloth. Remove any mineral deposits or residue.
- Remove the drip tray and wash it with warm, soapy water. Dry thoroughly before reattaching.
- Clean the exterior of the machine with a soft, damp cloth. Avoid abrasive cleaners that could damage the matte finish.
- 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.
- Pour the descaling solution into the water reservoir according to the instructions on the kit.
- Fill the reservoir with water to the max line.
- Place a large mug on the drip tray and run a brew cycle without a K-Cup. Repeat until the reservoir is empty.
- Let the machine sit for 30 minutes to allow the solution to work on scale buildup.
- 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.
