Keurig Not Making a Full Cup

If your Keurig is not brewing a full cup, there are several treatments for the problem. This issue is fairly common and can be resolved by descaling your coffee maker or cleaning the Keurig’s needles and reservoir tube. Also, shaking trapped air out of your device and replacing a faulty brew basket is helpful.

1. Descale Your Keurig Coffee Maker

Descale Your Keurig Coffee Maker

Naturally:

Your Keurig will accumulate mineral deposits, also known as limescale, and coffee grounds can get lodged in machine parts.

In addition:

These clogs limit the functionality of your Keurig and could be a likely cause for your partial servings of coffee.

As such:

To reduce the build-up of limescale in your reservoir, we recommend using filtered water and descaling regularly.

Descaling is a perfect way to get rid of the debris causing your Keurig device to malfunction.

To do this:

Fill the reservoir with an equal mixture of descaling solution or white vinegar and water, then run a brewing cycle.

After the cycle is complete:

Let the mixture sit for a few minutes to break down the mineral compounds in the tank.

Finally:

To eradicate any leftover debris, you should run multiple rinse cycles with plain water. Your Keurig should produce a full cup of steaming coffee after this simple maintenance hack.

2. Clean and Unclog Your Keurig Needles

Keurig The Entry and Exit Needles

Believe it or not:

Mineral compounds and debris like coffee grounds or foil commonly get stuck in the Keurig’s exit needles. This clog could likely be why your Keurig is not brewing full cups of coffee.

To that end:

A basic solution would be to clean and unclog your Keurig needles. But how do you go about this process?

Now:

There are two simple procedures to try. You can run a rinse cycle with plain water or insert a straightened paper clip to clear the lodged debris.

Either way:

Your Keurig should be back to its full capacity after trying these troubleshooting methods.

One more thing:

You should habitually run a rinse cycle to flush out clogs as a preventive measure.

3. Clean and Unclog the Water Reservoir Port

As expected:

Your Keurig coffee maker will not brew a full cup of coffee if the port connecting the water reservoir and the machine is clogged.

You see:

Mineral deposits and debris often lodge into machine parts, resulting in malfunctions.

Typically:

Descaling the Keurig should effectively solve this problem; however, there are other hacks you could try if it doesn’t properly work.

Look:

You can rinse the reservoir and manually clean the area where the tank connects to the machine.

You can also use high water or air pressure to attempt to dislodge and flush out the debris.

After this:

Your Keurig coffee machine should be as good as new and brew the right coffee portions.

4. Give Your Keurig a Shake or Tap to Release Trapped Air

Frequently:

Air gets trapped in the tubing system, limiting the outward flow of coffee during a brewing cycle.

Consequently:

This phenomenon could be why your Keurig is sputtering out insufficient amounts of coffee after brewing.

Off the record:

Give your Keurig a light tap or moderate shake to get the air loose and allow the brewing process to continue seamlessly.

Finally:

To prevent this from happening in the future, avoid letting the water reservoir get completely empty before giving it a refill.

All in all:

Sometimes all your Keurig needs is a loving nudge to get it to function right.

5. Avoid Removing the Water Reservoir During the Brewing Cycle

So:

You ran a cycle on your Keurig coffee maker, expecting a full cup of coffee only to be greeted with a measly serving.

Think back!

Did you remove the water reservoir during the brewing process?

Here’s the thing:

Tampering with, adjusting, or totally removing the water reservoir during a brewing cycle can affect the amount of coffee your Keurig turns out.

To fix this:

Set the water reservoir back in place and avoid moving it during a cycle. Then run a rinse cycle with plain water only to make sure the device is working fine.

6. Replace or Clean the Faulty Brew Basket

Listen:

If your Keurig is not brewing full cups of coffee, then it is likely that the brew basket is clogged or faulty. This problem is fairly common, so don’t be worried.

Now:

In the case of a clogged brew basket, you would need to spray it and leave it to soak for a few minutes. After this, you must scrub it clean with a soft-bristled brush.

In the same vein:

When the brew basket is damaged, you should replace it immediately.

Note:

You can call Keurig customer support for a free replacement if you haven’t used your brewer for more than a year. All you need is the serial number on the Keurig device, and you’re set.
