Clean the Needle and Water Pathways
- Turn off and unplug the Keurig for safety.
- Open the lid and carefully clean the K-Cup holder and needle with a paperclip or a needle cleaning tool to remove any obstructions.

Mineral deposits can cause inconsistent brewing. Use a descaling solution or a mixture of equal parts water and white vinegar.

- Repeat with fresh water to rinse thoroughly.
