Cleaning and Descaling Your Keurig
Mineral deposits from water can clog your brewer, affecting taste and performance. Regular descaling is vital, especially if you notice slower brewing or strange tastes.
Use a descaling solution or a mixture of equal parts white vinegar and water. Run the solution through a brewing cycle without a K-Cup, then rinse with fresh water to clear residues.
How to Fix Common Brewing Issues
- Brewer Won’t Turn On: Check the power cord and outlet. Reset by unplugging and replugging. Replace the outlet if needed.
- Brewing Too Slowly: Descale with a solution to remove mineral buildup.
- Leaks During Brewing: Ensure the water reservoir isn’t overfilled and the K-Cup pod is correctly inserted.
- No Water Flow: Check for clogs at the water inlet or the K-Cup holder. Clean as described below.
Cleaning the K-Cup Holder and Water Reservoir
Build-up of coffee oils and minerals can block water flow and affect taste. Regular cleaning keeps your brewer functioning properly.
Remove the K-Cup holder and rinse with warm water, scrubbing gently if needed. Wipe the water reservoir with a damp cloth and dry thoroughly before refilling.
Using Reusable Filters and Accessories
For cost savings and environmental benefits, consider using a reusable filter like the My K-Cup® Reusable Coffee Filter. It allows you to brew with your favorite ground coffee.
Ensure the reusable filter is properly seated and compatible with your K-Mini. Regularly clean it to prevent clogging and ensure flavor extraction.
