Perform Descaling to Remove Mineral Buildup
Mineral deposits can block water flow, causing incomplete brews. Use a descaling solution or white vinegar as follows:
- Fill the water reservoir with equal parts water and descaling solution (or vinegar).
- Run a brew cycle without a K-Cup, allowing the solution to pass through.
- Repeat with clean water to rinse out any residue.
Clean the Needle and Water Path
- Turn off and unplug your Keurig.
- Open the top and insert a paperclip into the needle to remove any clogs or debris.
- Run a water-only brew cycle to flush out residual debris.
Check Water Level and Reservoir
Ensure the water reservoir is filled to the recommended level and properly seated. Low water or misalignment can affect brewing volume.
Test and Confirm Fixes
Repeat a brew cycle after cleaning and descaling. If the cup fills correctly, the issue is resolved. If not, consider additional maintenance or professional servicing.
