Check the Water Reservoir
- Ensure the water reservoir is filled to the appropriate level with fresh water.
- Remove the reservoir and rinse it thoroughly to remove any buildup or debris.
- Reattach the reservoir securely to ensure proper connection.
Clean the Brew Needle
- Turn off and unplug your Keurig before cleaning.
- Lift the brewing head and inspect the needle for clogs or debris.
- Use a paperclip or needle cleaning tool to carefully clear any obstructions from the needle.
- Wipe the area with a damp cloth and reassemble.
Descale Your Keurig
Mineral buildup inside the machine can restrict water flow, leading to incomplete brews. Use a descaling solution or a mixture of equal parts water and vinegar.
- Fill the water reservoir with the descaling solution.
- Run a brew cycle without a K-Cup to flush the system.
- Repeat with clean water to rinse thoroughly.
Inspect and Replace Water Filter (if applicable)
If your Keurig has a water filter, check if it needs replacement. A dirty filter can restrict water flow.
- Remove the filter and replace it with a new one.
- Rinse the filter before installation.
- Run a brew cycle to ensure proper operation.
Test and Adjust Brew Size
Make sure you select the correct brew size (6-12oz). Sometimes, selecting a smaller size can cause the machine to not fill the cup fully.
- Choose the largest brew size to verify full capacity.
- Ensure the cup is placed correctly and not blocking the outlet.
