Step 2: Empty and Clean the Water Reservoir
- Remove the water reservoir and empty any remaining water.
- Wash it with warm, soapy water to remove mineral deposits or buildup.
- Rinse thoroughly and dry before reattaching.
Step 3: Descale the Brewer
Use a descaling solution suitable for Keurig brewers, such as the Keurig 3-Month Brewer Maintenance Kit, to remove mineral buildup. Follow these steps:
- Fill the water reservoir with a descaling solution or a mixture of equal parts water and white vinegar.
- Place a large cup on the drip tray.
- Run a brew cycle without a K-Cup, allowing the solution to flow through.
- Repeat with plain water to rinse out any residual solution.
Step 4: Check and Clear the Exit Needle
Obstructions in the exit needle can cause incomplete brewing. Use a paperclip or a Keurig needle cleaning tool to gently clear any clogs:
- Lift the needle cover, if accessible.
- Carefully insert the tool into the needle to dislodge any debris.
- Wipe the area clean with a damp cloth.
Step 5: Test the Brewer and Adjust if Needed
Reassemble all parts, fill the reservoir with fresh water, and run a test brew. If the cup fills properly, your issue is resolved. If not, repeat descaling or cleaning steps, or consider replacing parts like the water filter if applicable.
