Why Is My Nespresso Machine Not Making a Full Cup? (5 Fixes)

Have you ever been ready for your morning coffee, only to find that your Nespresso machine is giving you less than a full cup? Frustrating, isn’t it? But, don’t worry, you are not alone.

This is something every Nespresso user can experience, but the good news is that it is usually easy to fix.

Let’s find out why this is happening and how you can solve the issue.

Why Isn’t My Nespresso Machine Making a Full Cup?

There are several reasons why your Nespresso machine is not making the right amount of coffee. Understanding these reasons is the first step toward solving the problem.

Descale Is Needed

Just like other coffee machines, Nespresso machines need regular descaling to remove calcium deposits from water. If haven’t descaled your Nespresso machine recently, this could be affecting the performance of your machine.

Capsule Issues

Sometimes, the problem could be with the coffee capsule itself. It is possible that it isn’t inserted properly, or there could be an issue with the capsule barcode.

Water Tank Problems

Check if your water tank is properly seated and filled. A misaligned tank or insufficient water can lead to incomplete cups.

Programming Needs Reset

Nespresso machines come with programmable cup sizes. If your settings have been accidentally altered, your machine might not make the correct amount of coffee.

Pump Or Internal Issues

If your machine has an internal issue, such as a failing pump, it might not be able to dispense the correct amount of water.

5 Ways To Solve Your Nespresso Cup Fill Problems

Now that we have identified the possible reasons, let’s go through the solutions:

Descale Your Nespresso Machine

To do this properly you will need a Nespresso descaling solution or a suitable alternative, and fresh water.


  1. Empty the drip tray and remove any capsules.
  2. Fill the water tank with the descaling solution and an equal part of water.
  3. Enter the machine into descaling mode (consult your machine’s manual as this varies by model).
  4. Place a container under the coffee outlet and start the descaling process. The solution will run through the machine, removing any limescale and mineral build-up.
  5. After descaling, refill the water tank with fresh water and run it through the machine several times to rinse out any remaining descaling solution.
  6. Follow your machine instructions to exit the descaling mode.

Check The Capsule And Its Compartment

This solution requires you to have a soft, damp cloth.


  1. Eject any capsule currently in the machine.
  2. Check the capsule compartment for any debris or leftover coffee grounds and clean it thoroughly with the damp cloth.
  3. Insert a new capsule. Make sure it is not damaged and is inserted correctly according to your machine’s instructions.

Align The Water Tank Properly

You don’t need anything for this solution, just your hands and eyes.


  1. Remove the water tank and check for any cracks or damages.
  2. Fill the tank with fresh water up to the maximum level mark.
  3. Carefully reattach the water tank to the machine, making sure it is properly aligned and securely in place.

Reset Or Adjust Your Cup Size

For this solution, you are going to need your Nespresso machine and its manual, mainly because adjusting or resetting the cup sizes can be different between models.


  1. Check the manual. Each Nespresso machine has a different method for adjusting and resetting cup sizes, so refer to your machine’s manual for specific instructions.
  2. Generally, you can set the cup size by holding down one of the brew buttons until you get the desired amount of coffee. In addition, to get back to the default settings you need to push the lever down for 3 seconds. Then push the button and the lever down for 3 seconds.
  3. Brew a cup of coffee to make sure the new settings are just the way you like it.

Contact Support

For this solution, you will need the Contact information for Nespresso customer service or a professional repair service.


  1. If your machine is still not working correctly after trying the above steps, contact Nespresso support.
  2. Be ready to provide your machine’s model, serial number, and a description of the issue.
  3. If recommended by Nespresso, take your machine to a professional repair service or follow the company’s instructions for sending it in for repair.
