Check Water Level and Reservoir
- Ensure the water reservoir is filled to the appropriate level, at least 6oz for a minimal brew.
- Remove and clean the reservoir if it appears dirty or obstructed.
Perform a Descaling Cycle
Mineral deposits can clog internal components, reducing water flow. Use a descaling solution or a mixture of equal parts vinegar and water.
- Fill the water reservoir with the descaling solution or vinegar mixture.
- Run a brew cycle without a K-Cup, allowing the solution to flow through the machine.
- Repeat with clean water to rinse out any residue.
Clean the Needle and Pod Holder
- Turn off the machine and unplug it.
- Remove the used K-Cup or reusable filter, if present.
- Use a paperclip or Keurig needle cleaning tool to clear any clogs in the needle.
- Wipe the needle area with a damp cloth.
Inspect and Clear the Water Path
Check for any visible blockages or build-up in the water flow path. Use a soft brush or cloth to remove debris.
Test and Adjust Settings
Ensure you’ve selected the correct brew size (6-12oz). If issues persist, reset the machine or try a different brew size.
