Clean the Needle and Brew Path
- Turn off the machine and unplug it for safety.
- Open the top and locate the needle that punctures the K-Cup.
- Use a paperclip or a Keurig cleaning tool to gently clear any clogs or coffee grounds blocking the needle.

Descale the Coffee Maker
Mineral deposits can cause water flow issues, leading to partial brews. Use a descaling product like the Keurig Descaling Solution or similar approved cleaner.

- Run several brewing cycles without a K-Cup until the reservoir is empty.
- Rinse thoroughly by running 2-3 cycles with clean water.
Inspect and Clean the Brew Chamber
Residue or mold can accumulate inside the brew chamber, affecting water flow.
- Remove and clean the brew chamber and surrounding areas with a damp cloth.
- Check for any visible blockages or mold and clean thoroughly.
Test the Machine
- Fill the reservoir with fresh water.
- Run a brew cycle to confirm full cup brewing.
- If the problem persists, repeat descaling or check for other blockages.
