In this blog post, we will explore the causes of low pressure in Breville dual boilers, troubleshooting steps to fix the issue, and preventative measures to avoid it in the future. Inconsistent tamping or dosing of espresso grounds”

Common causes of low pressure in Breville dual boilers:

Low pressure in a Breville dual boiler can be caused by a number of issues. Here are some common causes that you should be aware of:

Scale buildup in the boiler and/or group head:

Scale buildup is a common problem in espresso machines that use hard water. When minerals like calcium and magnesium accumulate in the boiler and group head, they can obstruct the flow of water and reduce the pressure. If left unchecked, scale buildup can also damage the machine’s internal components. To prevent this, it is recommended to descale the machine regularly with a descaling solution.

Clogged or dirty filters:

The filters in your Breville dual boiler are responsible for filtering out the espresso grounds and ensuring a smooth and consistent flow of water. If these filters become clogged or dirty, the pressure can drop. To fix this issue, you should clean the filters regularly and replace them when necessary.

Malfunctioning pressure gauge or control board:

If the pressure gauge or control board in your Breville dual boiler is not functioning properly, it can cause the machine to operate at a lower pressure than desired. To troubleshoot this issue, you can check the gauge for accuracy, and if it is not reading correctly, you may need to replace it. If the control board is the issue, you may need to contact Breville customer support for further assistance.

Inconsistent tamping or dosing of espresso grounds:

The quality of your espresso can be greatly affected by the consistency of tamping and dosing. Inconsistent tamping or dosing of the espresso grounds can cause variations in the resistance to the water flow, leading to low pressure. Ensure you are using the correct amount of espresso grounds and tamp them evenly before brewing.

Secret Solutions

Insufficient Water Supply 

One common reason for the Breville Dual Boiler not operating at full pressure is an insufficient water supply. Before brewing, ensure that the water tank is adequately filled and properly seated in its place. Additionally, check if the water filter is clean and not clogged, as this can restrict water flow and result in lower pressure. Regularly descaling your machine can also help prevent any blockages caused by mineral deposits. 

Grind Size and Tamping 

Another factor that can affect the pressure output is the grind size and tamping technique. If the coffee grounds are too fine or too coarse, it can impact the flow rate and subsequently reduce the pressure. Adjusting the grind size to a finer or coarser setting, depending on your preference, can help optimize the pressure. Similarly, ensuring proper tamping technique, applying consistent pressure, and distributing the grounds evenly in the portafilter can also improve the extraction process. 

Machine Maintenance 

Regular maintenance is crucial for the optimal functioning of any espresso machine. The Breville Dual Boiler requires periodic cleaning and maintenance to ensure it operates at its best. Cleaning the shower screen, group head, and portafilter regularly can prevent any buildup that may impede water flow and pressure. Additionally, checking and replacing worn-out gaskets or seals can help maintain proper pressure levels.

Why does my Breville have low pressure? 

There can be several reasons why your Breville machine might have low pressure. Here are a few possible causes:

  1. Coffee grind size: If the coffee grounds are too fine, they can create excessive resistance, leading to low pressure. Try adjusting the grind size to a coarser setting.
  2. Coffee dose: Using too much coffee in the portafilter can restrict water flow and result in low pressure. Ensure that you’re using the recommended dose for your machine.
  3. Coffee tamp: Inadequate tamping can cause uneven water distribution, leading to low pressure. Make sure you’re tamping the coffee evenly and with the correct pressure.
  4. Water flow: Check if there are any obstructions or blockages in the water line or the machine’s valves. Clean and descale the machine regularly to prevent mineral buildup that can impede water flow.

How do you adjust the pressure on a Breville dual boiler? 

To adjust the pressure on a Breville dual boiler espresso machine, you’ll typically need to access the machine’s settings menu. The exact steps may vary depending on the specific model you have, but here’s a general guideline:

  1. Turn on the machine and allow it to warm up.
  2. Locate the settings or menu button on the machine. It is usually labeled or represented by an icon.
  3. Press the settings/menu button to enter the menu.
  4. Navigate through the menu options until you find the pressure adjustment setting. This setting may be labeled as “pressure,” “brew pressure,” or similar.
  5. Use the arrow buttons or the dial, if available, to increase or decrease the pressure setting. The specific pressure range will depend on your machine model and personal preference.
  6. Once you’ve adjusted the pressure, save the setting and exit the menu.

How do I get the right pressure in Breville? 

To achieve the right pressure with your Breville espresso machine, follow these general guidelines:

  1. Grind size: Ensure that you’re using the appropriate grind size for your desired brewing method. Experiment with different grind settings to find the sweet spot where the water flow is balanced, resulting in the right pressure.
  2. Coffee dose: Use the recommended dose of coffee for your machine and adjust as needed. Using too much coffee can restrict water flow, while using too little may result in weak extraction and low pressure.
  3. Tamping: Consistently tamp the coffee evenly and with the right amount of pressure. This helps create an even surface for water distribution, leading to better pressure during extraction.
  4. Water quality: Use filtered water or water with low mineral content to prevent scaling and potential blockages that can affect pressure. Regularly descale your machine to remove any buildup.

What pressure is the pump on the Breville dual boiler? 

The pump pressure on a Breville dual boiler espresso machine is typically set to around 9 bars. This pressure range is commonly used in espresso machines to achieve optimal extraction. However, it’s important to note that different Breville models may have slight variations in the default pump pressure setting.

While 9 bars is a common standard, it’s worth mentioning that the pressure alone doesn’t guarantee the perfect espresso. Other factors, such as grind size, coffee dose, tamping, and water quality, also play important roles in achieving a balanced and flavorful extraction.
