Cleaning the Exterior and Drip Tray
- Wipe down the exterior with a damp, soft cloth to remove dust and coffee splashes.
- Remove the drip tray and rinse it thoroughly with warm water. Use a soft brush if needed to dislodge any stubborn residue.
- Dry all parts with a clean towel before reassembling.
Cleaning the Water Reservoir and Accessory
Detach the water reservoir and wash it with warm, soapy water. Rinse thoroughly and dry before reattaching. If your model uses a water filter, replace it periodically as recommended by the manufacturer to ensure optimal water quality.
Descaling Your Keurig K-Mini
- Fill the water reservoir with a descaling solution mixed with water, following the instructions on the descaling product.
- Place a large mug on the drip tray and run a brew cycle without a K-Cup, allowing the solution to flow through.
- Repeat the process until the reservoir is empty, then let the machine sit for 20 minutes to allow the solution to break down mineral deposits.
- Run several plain water brew cycles to rinse out any remaining descaling solution.
Troubleshooting Common Issues
- Weak or no water flow: Check for clogs or mineral buildup. Descale the machine and clean the needle port if necessary.
- Leaking: Ensure all parts are assembled correctly and the water reservoir is seated properly.
- Inconsistent brew size: Clean or replace the water filter and check for blockages.
