Are you frustrated with your Keurig coffee maker only brewing half a cup of coffee? You’re not alone. Many Keurig users have experienced this issue, and it can be caused by a variety of factors. In this article, we’ll explore the possible reasons why your Keurig is only brewing half a cup of coffee and provide you with troubleshooting steps and solutions to get your coffee maker working properly again.
Understanding How Keurig Coffee Makers Work
Before we dive into the possible causes of the issue, it’s essential to understand how Keurig coffee makers work. Keurig coffee makers use a single-serve brewing system, which involves inserting a K-cup into the machine, selecting the desired brew size, and waiting for the coffee to be dispensed. The machine uses a combination of water pressure and temperature to extract the flavors and oils from the coffee grounds in the K-cup.
The Brewing Process
The brewing process in a Keurig coffee maker involves the following steps:
- Water is pumped from the water reservoir into the machine’s boiler.
- The water is heated to the optimal temperature for brewing coffee.
- The heated water is then pumped through the K-cup, which is pierced by a needle to allow the water to flow through.
- The coffee is dispensed into the cup, and the used K-cup is ejected from the machine.
Possible Causes of the Issue
Now that we understand how Keurig coffee makers work, let’s explore the possible causes of the issue:
Clogged Water Reservoir or Water Line
A clogged water reservoir or water line can restrict the flow of water into the machine, resulting in a half cup of coffee. Check the water reservoir and water line for any blockages or mineral buildup. Descale your Keurig regularly to prevent mineral buildup.
Incorrect Brew Size Selection
Make sure you’re selecting the correct brew size on your Keurig. If you’re selecting a smaller brew size, you’ll only get a half cup of coffee. Try selecting a larger brew size to see if that resolves the issue.
Low Water Pressure
Low water pressure can also cause your Keurig to only brew half a cup of coffee. Check the water pressure in your home to ensure it’s within the recommended range for your Keurig model.
Clogged K-cup Holder or Needle
A clogged K-cup holder or needle can prevent the water from flowing through the K-cup properly, resulting in a half cup of coffee. Check the K-cup holder and needle for any blockages or buildup. Clean the K-cup holder and needle regularly to prevent clogs.
Worn or Damaged Seals
Worn or damaged seals in the Keurig’s brewing system can cause leaks, which can result in a half cup of coffee. Inspect the seals for any signs of wear or damage. Replace the seals if necessary.
Scale Buildup
Scale buildup in the Keurig’s brewing system can restrict the flow of water, resulting in a half cup of coffee. Descale your Keurig regularly to prevent scale buildup.
Old or Expired K-cups
Using old or expired K-cups can affect the flavor and quality of your coffee. Try using fresh K-cups to see if that resolves the issue.

Why does my Keurig only brew half a cup of coffee?
Your Keurig may be brewing only half a cup of coffee due to a clogged water filter or a buildup of scale and mineral deposits within the machine. Over time, these deposits can reduce the water flow, resulting in a weaker or shorter brew. Regular descaling and cleaning of the machine can help resolve this issue.
Another possible cause could be a malfunctioning or faulty water pump. If the pump is not functioning correctly, it may not be able to draw enough water to fill the cup. In this case, you may need to contact Keurig’s customer support for further assistance or consider replacing the machine.
How do I descale my Keurig to resolve the half-cup issue?
Descaling your Keurig involves using a mixture of water and a descaling solution to remove mineral deposits and scale buildup. You can purchase a Keurig-approved descaling solution or use a mixture of equal parts water and white vinegar. Run the solution through the machine, following the manufacturer’s instructions, to help dissolve and remove any buildup.
After descaling, run several cycles of just water through the machine to rinse out any remaining solution. This will help ensure your coffee tastes fresh and clean. It’s recommended to descale your Keurig every 3-6 months, depending on usage, to prevent scale buildup and maintain optimal performance.
Can a clogged water filter cause my Keurig to brew only half a cup?
Yes, a clogged water filter can definitely cause your Keurig to brew only half a cup of coffee. The water filter is designed to remove impurities and contaminants from the water, but if it becomes clogged, it can restrict the water flow, resulting in a weaker or shorter brew. Check your water filter regularly and replace it every 6-12 months or as recommended by the manufacturer.
If you suspect a clogged water filter, try removing and cleaning it according to the manufacturer’s instructions. If the issue persists, consider replacing the filter with a new one. This should help restore the normal water flow and brewing performance of your Keurig.
How do I clean my Keurig’s brew head to resolve the half-cup issue?
Cleaning your Keurig’s brew head involves removing any buildup or debris that may be restricting the water flow. Start by turning off and unplugging the machine, then remove any K-cups or water from the reservoir. Use a mixture of equal parts water and white vinegar to soak the brew head, then use a soft brush or cloth to gently scrub away any buildup.
After cleaning the brew head, rinse it thoroughly with water to remove any remaining vinegar solution. Reassemble the machine and run several cycles of just water through it to test the brewing performance. Regular cleaning of the brew head can help prevent buildup and maintain optimal performance.
Can a faulty K-cup cause my Keurig to brew only half a cup?
Yes, a faulty K-cup can cause your Keurig to brew only half a cup of coffee. If the K-cup is not punctured correctly or is damaged, it can restrict the water flow, resulting in a weaker or shorter brew. Try using a different K-cup to see if the issue persists. If it does, the problem may be with the machine rather than the K-cup.
If you suspect a faulty K-cup, check the packaging for any damage or defects. You can also try contacting the manufacturer for a replacement or refund. In the meantime, try using a different K-cup to see if the issue resolves itself.
How do I reset my Keurig to resolve the half-cup issue?
Resetting your Keurig involves unplugging the machine, waiting for 30 seconds, and then plugging it back in. This can sometimes resolve issues with the machine’s electronics or programming. After resetting the machine, try brewing a cup of coffee to see if the issue persists.
If resetting the machine does not resolve the issue, you may need to try more advanced troubleshooting steps or contact Keurig’s customer support for further assistance. In some cases, a reset may not be enough to resolve the issue, and more extensive repairs or maintenance may be required.
When should I contact Keurig’s customer support for assistance with the half-cup issue?
You should contact Keurig’s customer support if you have tried all the troubleshooting steps and the issue persists. If you are unsure about how to descale or clean your Keurig, or if you suspect a faulty water pump or other internal issue, it’s best to contact the manufacturer for assistance.
