Clean the Brewer
Use a descaling solution or a mixture of vinegar and water to remove mineral buildup inside the machine. Run a cleaning cycle as instructed in your user manual, then rinse thoroughly with fresh water.
Check Cup Placement and Drip Tray
An improper placement can interfere with the brewing process and cause short pours.
Perform Descaling and Maintenance
Regularly descale your Keurig K-Mini every 3-6 months using a descaling kit or vinegar solution. This prevents mineral deposits from clogging internal components and ensures full cups each time.
