| Filter Maintenance | Replace or clean water filters for optimal performance. |
Check the Water Reservoir
- Ensure the water reservoir is filled with fresh water.
- Remove the reservoir and rinse it thoroughly.
- Re-seat the reservoir securely in its place.
Clean the Needle
- Turn off and unplug your Keurig.
- Lift the handle and inspect the needle for clogs or debris.
- Use a straightened paperclip or the cleaning tool provided to gently clear any blockages.
- Run a water-only brew cycle to test.
Descale the Machine
Mineral deposits can restrict water flow. Use a descaling solution or a mixture of equal parts water and white vinegar.
- Fill the water reservoir with the descaling mixture.
- Run a brew cycle without a K-Cup pod.
- Repeat with plain water to rinse.
Inspect and Clean the Water Filter
If your model has a water filter, remove and clean or replace it according to the manufacturer’s instructions. A clogged filter can reduce water flow.
Test the Brewer
After completing the above steps, brew a full cup to check if the issue is resolved. Repeat descaling periodically to maintain performance.
