What To Know
- Air can get trapped in the water reservoir or the coffee maker’s internal system, creating a blockage that prevents water from flowing.
- Turn on the coffee maker and allow it to run a brew cycle without a K-Cup.
- By following the troubleshooting steps outlined in this guide, you can effectively resolve the issue of your Keurig coffee maker not brewing a full cup.
Keurig coffee makers are known for their convenience and ease of use. However, when your Keurig coffee maker stops brewing a full cup, it can be frustrating. Fortunately, there are several troubleshooting steps you can take to resolve this issue.
Causes of a Keurig Coffee Maker Not Brewing a Full Cup
- Clogged Needle: The needle that punctures the coffee pod can become clogged with coffee grounds or other debris, preventing water from flowing through properly.
- Air Lock: Air can get trapped in the water reservoir or the coffee maker’s internal system, creating a blockage that prevents water from flowing.
- Defective Water Pump: The water pump is responsible for pumping water into the coffee maker’s system. If the pump is defective, it may not be able to generate enough pressure to brew a full cup.
- Scale Buildup: Mineral buildup from hard water can accumulate inside the coffee maker, clogging passages and restricting water flow.
- Dirty Reservoir: A dirty water reservoir can harbor bacteria and mold, which can affect water flow and coffee taste.
- Incorrect Pod: Using an incompatible or damaged coffee pod can prevent the needle from puncturing it properly, resulting in an incomplete brew.
- Electrical Issues: Faulty wiring or a damaged power cord can disrupt the coffee maker’s electrical system, affecting its ability to brew properly.

1. Clean the Needle:
