Step 1: Empty and Rinse the Water Reservoir

- Remove the water reservoir and empty any remaining water.
- Rinse the reservoir thoroughly with clean water to remove any residues or mold.
Step 2: Clean the Brew Basket and Needle
- Remove the brew basket and rinse it with warm water.

- Ensure no coffee grounds or debris are blocking the needle or spray head.
Step 3: Descale Your Keurig
- Fill the water reservoir with a descaling solution or a mixture of equal parts white vinegar and water.
