This blog post will guide you through troubleshooting common problems and provide solutions to get your coffee maker up and running again.

Common Causes of Keurig K-Duo Brewing Issues

1. Empty Water Reservoir: Ensure the water reservoir is filled with fresh, cold water.
2. Clogged Needles: The piercing needles in the K-Cup holder can become clogged with coffee grounds, preventing water flow.
3. Dirty Filter: A dirty filter can restrict water movement and cause insufficient brewing.
4. Air Lock: An air lock can occur when air enters the water line, blocking the flow of water.
5. Faulty Pump: The pump is responsible for circulating water through the machine. A faulty pump can prevent brewing.
6. Electrical Issues: Loose connections or faulty electrical components can hinder the machine’s operation.
7. Descaling Required: Mineral buildup from hard water can accumulate in the machine, affecting brewing performance.
