Key Takeaways
| Regular cleaning is essential | Mineral deposits and residue can cause brewing issues. |
| Descaling prolongs your machine’s life | Use descaling solutions every 3 months. |
| Check for clogs | Blocked needles or water lines reduce brew volume. |
| Ensure proper reservoir placement | Incorrect water level or placement affects brewing. |
Check and Refill the Water Reservoir
- Ensure the water reservoir is properly seated and filled with fresh water.
- Remove and inspect the reservoir for any cracks or blockages.
- Refill to the MAX line if necessary, and make sure it’s correctly placed back in the machine.
Clean the Needle and Brew Path
- Turn off the machine and unplug it for safety.
- Use a paperclip or a Keurig cleaning tool to gently clear the exit needle and the entry needle of any debris or coffee grounds.
- Run a descaling cycle or brew water without a pod to flush the lines.
Descale Your Keurig
Mineral buildup can cause poor brewing performance. Use a descaling solution or a mixture of equal parts water and white vinegar. Follow these steps:
- Fill the water reservoir with the descaling solution.
- Run a brewing cycle without a pod, allowing the solution to flow through.
- Repeat with clean water to rinse the system thoroughly.
Check for Clogged or Faulty Parts
Inspect the brew basket and needle for clogs or residue. If you notice buildup, clean them thoroughly. Also, verify that the drip tray and water reservoir are positioned correctly.
Test and Confirm Fix
After cleaning and descaling, run several water-only brews to test if the cup fills properly. Adjust or repeat cleaning if necessary. If issues persist, consider replacing the reusable filter or contacting customer support.
