Spread The Love!

If you’re a coffee lover, you know how important it is to have the right equipment to make the perfect cup of espresso.

One popular option is the Breville espresso machine, which boasts a reputation for producing high-quality espresso with ease.

However, what do you do when your Breville espresso machine starts to lose pressure and the espresso it produces is not up to par?

In this blog post, we’ll explore the common causes of no pressure in Breville espresso machines and offer tips and solutions to help you get back to brewing delicious espresso in no time.

Why Is Pressure Important for a Breville Espresso Machine?

Pressure is a critical component when it comes to making a great cup of espresso with a Breville espresso machine. Without sufficient pressure, your espresso shot may lack the crema and flavor that make it so desirable.

In general, a Breville espresso machine should produce a pressure of around 9 bars during the brewing process. This pressure is necessary to extract the flavors and aromas from the coffee grounds and create a thick, creamy layer of crema on top of the espresso shot.

During the extraction process of your Breville espresso machine, you can check the pressure by looking at its pressure gauge. Ideally, the gauge should display a pressure of around 9 bars, which is considered optimal for making a great espresso shot.

However, it’s important to note that if the pressure gauge shows a reading that is either too high or too low, it can lead to potential issues with the quality and consistency of your espresso.

Therefore, it’s crucial to pay attention to the pressure gauge and address any abnormal readings to ensure that your Breville espresso machine is functioning properly.

Without proper pressure, the water won’t be able to pass through the coffee grounds effectively, resulting in under-extracted and weak-tasting espresso.

In addition, a lack of pressure can cause the machine to produce inconsistent shots, which can be frustrating if you’re trying to perfect your barista skills.

If you notice that your Breville espresso machine is producing no pressure or lower pressure than usual, it’s important to address the issue as soon as possible to ensure that you’re getting the most out of your machine and your coffee.

Why Does My Breville Espresso Machine Have No Pressure?

There’s nothing more disappointing than pressing the button on your Breville espresso machine and finding out that there’s no pressure. It’s a common problem that can be caused by various factors.

In this section, we will discuss the 7 common reasons why your Breville espresso machine has no pressure.

From a broken pressure gauge to not using the correct grind size, we’ll cover everything you need to know to troubleshoot your machine and get back to enjoying a delicious cup of espresso.

1. A Broken Pressure Gauge

If your Breville espresso machine’s pressure gauge is not providing accurate readings, it may need to be calibrated.

Calibration involves adjusting the gauge to ensure that it is accurate and providing correct pressure readings.

This is especially important for ensuring that your espresso shots are consistent and of high quality.

Calibration is a technical process that requires specialized knowledge and equipment. It is recommended to have the gauge calibrated by a certified technician to ensure accuracy.

Attempting to calibrate the gauge yourself can lead to further damage or incorrect readings.

In some cases, the pressure gauge may be beyond repair and require a replacement. If the gauge is broken, it is recommended to take the espresso machine to a licensed repair shop.

A professional technician can assess the issue and determine whether the gauge needs to be replaced or if any other underlying issues need to be addressed.

Before agreeing to a seal or gasket replacement, it’s important to confirm whether the pressure problem is primarily caused by a faulty gauge.

This is because replacing a gauge is typically easier than replacing a seal or gasket.

By identifying the root cause of the pressure problem, you can ensure that the appropriate repair is performed and prevent unnecessary expenses.

A broken or inaccurate pressure gauge can significantly affect the performance of your Breville espresso machine and the quality of your espresso shots.

If you notice any issues with the pressure gauge, it’s crucial to have it calibrated or repaired by a professional technician to ensure accurate readings and consistent results.

2. Broken Seal or Gasket

A broken seal or gasket in a Breville espresso machine can result in pressure issues, causing the machine to not reach the right pressure setting.

The gasket plays a crucial role in ensuring a tight seal between the bottom and top of the machine, creating an airtight environment for the brewer to function normally.

If you suspect that the seal or gasket is damaged, it is recommended to take your espresso machine to a licensed repair shop for diagnosis and repair.

It’s important to confirm whether the gauge is the primary cause of the pressure issue before agreeing to a seal or gasket replacement, as replacing a bad gauge is typically easier than installing a new seal or gasket.

Another common issue that may occur with your Breville espresso machine is leakage from the bottom, particularly after brewing a cup of coffee.

However, if the seal or gasket is the primary issue, a licensed technician can replace it with a new one to restore your machine’s functionality.

3. The Water Line Might Be Clogged

Clogged water lines can cause a lot of issues with your Breville espresso machine. If you notice that the water reservoir is blocked, it could be a sign of a clogged line caused by debris, mineral buildup, or a buildup of coffee grounds.

This could lead to low pressure and reduced water flow, affecting the overall performance of the machine.

Using tap water instead of filtered water can also cause a clogged water line, as tap water often contains more minerals that can accumulate over time.

To fix a clogged water line, you can try cleaning the group head and shower head with a brush to remove any limescale buildup.

Regularly descaling your machine can also help prevent mineral buildup and clogs. If the issue persists, you may need to replace the water tube inside the machine.

It is important to take care of your Breville espresso machine to prevent issues like a clogged water line.

Using filtered water and regularly cleaning the machine can help prevent mineral buildup and other issues that can affect the quality of your espresso.

4. Not Using The Correct Dose Of Ground Beans

One of the essential factors in brewing a great shot of espresso is using the correct dose of ground coffee beans.

When using the tamper to press the ground coffee beans in the portafilter, you should be able to see the silver ring on the tamper after fully pressing it down.

If the silver edge of the tamper is not visible, it’s a sign that you’re not using enough ground coffee beans.

To ensure that you’re using the correct dose of ground beans, it’s recommended to always use the two-cup basket that comes with the Breville Barista Express.

The machine is specifically designed for the two-cup basket, so using it will help you achieve the perfect dose of coffee.

When you purchase the Barista Express, it comes with a razor tool that can be used to measure the exact amount of ground beans needed in the portafilter.

This tool ensures that you’re using the right dose of coffee and can help you achieve a perfect shot of espresso every time.

5. Not Tamping The Coffee

Not tamping the coffee properly is a common mistake that can cause issues with a Breville espresso machine.

Tamping is the process of compressing the coffee grounds into a compact puck using a tamper.

This step is essential in the brewing process, as it helps to create the necessary pressure for a good shot of espresso.

If the coffee is not tamped properly, the water will flow through the coffee too quickly, resulting in low pressure and a weak shot.

To avoid this, make sure to use the correct amount of coffee and tamp it down firmly and evenly.

It is also important to distribute the coffee grounds evenly in the portafilter before tamping to ensure consistent extraction.

By properly tamping the coffee, you can help to ensure that your Breville espresso machine is functioning at its best and producing high-quality shots.

6. Not Using The Correct Grind Size

Not using the correct grind size is a common mistake when making espresso with a Breville espresso machine.

Each type of coffee bean requires a specific grind size to achieve optimal results.

If the grind size is too coarse, the water will flow too quickly through the coffee and produce a weak shot with low pressure.

On the other hand, if the grind size is too fine, the water will not be able to pass through the coffee at all, resulting in no shot at all.

The ideal grind size for espresso is fine and consistent, similar to table salt.

To find the correct grind size for your espresso, you may need to experiment with different settings on your grinder.

It’s essential to take note of the grind size settings and make adjustments to achieve the right texture for your coffee.

If your Breville espresso machine has a built-in grinder, you can adjust the grind size by turning the dial on the machine.

It’s essential to use fresh beans for each shot and to clean the grinder regularly to ensure consistent results.

Using the incorrect grind size can result in low pressure in a Breville espresso machine.

To achieve the perfect shot, you need to find the right grind size that matches the type of coffee bean you are using.

Experimenting with different grind settings and keeping the grinder clean will help you achieve the best results.

7. Adjusting The Top Burr Grind Setting

The last solution on this list will be adjusting the top burr grind setting on a Breville espresso machine which can be another solution to fix low pressure.

Breville offers different ways to adjust the top burr grind setting depending on the machine model.

For example, the Barista Pro has 30 grind settings, and the grind dial is in the center. To adjust the grind size, turn the dial clockwise to make it finer and counterclockwise to make it coarser.

The Barista Express, on the other hand, has 16 settings to choose from, and the grind dial is located on the side of the machine. To adjust the grind size, turn the Grind Dial manually.

And if you have a Breville Smart Grinder Pro, you can adjust the range of grind sizes available with the grind size dial by adjusting the top burr.

It’s essential to note that adjusting the grind size can help you achieve the ideal extraction and create the perfect cup of coffee to suit your taste.
