If you are noticing that your Breville coffee machine is not producing enough pressure or no pressure at all, there are a few potential causes to investigate. Proper pressure is crucial for extracting flavor from coffee grounds and creating espresso-based drinks. Thankfully, most causes of low or no pressure on a Breville machine can be addressed with some troubleshooting and maintenance.
Check for Obstructions in the Portafilter
One of the most common reasons for lack of pressure on a Breville espresso machine is obstructions in the portafilter (the handle where the filter basket is locked in place). If there are obstructions in the portafilter, this can prevent water from flowing through properly and building up pressure. Here are some things to check:
- Make sure the portafilter is clean – Use a small brush to clean out any residual grounds that may be clogging the spouts
- Inspect the filter basket – Remove it from the portafilter and check for damage or blockages
- Try a different filter basket – Switch to a single shot rather than double shot basket, or vice versa
- Ensure the portafilter is inserted and rotated all the way – It needs to be fully locked into the group head for proper pressure
Taking the time to clean and inspect the portafilter can help dislodge any obstructions and restore proper pressure.
Check the Water Tank and Tubing
Issues with the water supply can also lead to problems with pressure. Here are some water system components to inspect:
- Water tank – Make sure it is full and properly inserted
- Water tubing – Check along the tubing for any kinks or blockages
- Water intake screen – Clean out any debris clogging the screen
- Water filter – Replace expired water filters
It’s a good idea to periodically descale your Breville machine to remove mineral deposits that can build up in the water lines and impact pressure. Refer to your owner’s manual for the descaling procedure.
Examine the Pump
The internal pump is responsible for pushing water through the heating system to brew espresso at the right pressure. Here are some signs of issues with the pump:
- No noise or vibration when brewing – The pump may not be turning on
- Weak noise or vibration – Indicates low pump pressure
- Leaking water near the pump – Points to a failing pump seal
If the pump seems to be malfunctioning, contact Breville support. The pump may need to be repaired or replaced. This repair requires technical skill and experience.
Check for Heating System Issues
Proper heating is crucial for generating pressure and extracting espresso. Here are some things to inspect in the heating system:
- Thermoblock or thermojet – Scale buildup reduces heating ability, descale regularly
- Temperature settings – Ensure not set too low to properly heat water
- Damaged heating element – May need repair or replacement
Watch the brewing process closely – if water flows through but does not get hot, there could be an issue with the heating element or temperature controls.
Inspect the Boiler
On Breville models with an internal boiler, low or no pressure can point to boiler problems. Check for these warning signs:
- Boiler temperature too low – Adjust to recommended 200-205°F
- Leaks or cracks in boiler tank – May need replacement
- Sputtering or pulsing flow – Indicates limescale buildup in boiler
- Failure to heat up – Could point to element or thermostat issue
Descale the boiler regularly to help prevent scale accumulation. Have a technician inspect the boiler if you suspect internal damage or failure.
Ensure Proper Coffee Dose and Tamp
While not a machine issue per se, an improper coffee dose or tamp can lead to problems with pressure. Follow these tips:
- Use recommended dose – Usually 14-18g for a double shot
- Distribute grounds evenly before tamping
- Tamp consistently with 30-40 lbs of pressure
- Make sure tamp is level and grounds are compressed evenly
- Avoid overfilling filter basket (causes resistance)
The dose, distribution, and tamp can significantly impact how easily water flows through the coffee puck. Taking care with these factors helps optimize pressure.
Perform Regular Maintenance
Like any appliance, espresso machines need regular maintenance to prevent issues like loss of pressure. Follow the manufacturer’s suggested schedule for tasks like:
- Backflushing – Helps clean brew head
- Descaling – Removes damaging mineral deposits
- Water filter changes – Provides clean water supply
- Part replacement – Worn parts like seals can cause problems
- Cleaning – Keeps components clear of debris buildup
Preventative maintenance helps maximize your Breville machine’s performance and lifespan.
Reset to Factory Settings
For computerized Breville models, resetting the machine to factory default settings can help resolve unexplained issues like lack of pressure:
- Power off the machine
- Hold down the “1-Cup” and “2-Cup” buttons together
- Power the machine back on while continuing to hold the buttons
- Release the buttons once the display indicates reset to factory settings
- The machine will power off and reset parameters
This can clear up any programming errors causing problems with pressure. Check the user manual for reset instructions specific to your model.
Contact Breville Support
If you have thoroughly tried the troubleshooting steps above but the machine still does not produce adequate pressure, it’s time to contact Breville support. They can provide additional customized troubleshooting or set up a repair if needed. Call the Breville support line or start a live chat on their website.
Be prepared to provide your machine’s model number and serial number. This helps the tech identify your exact machine and any common issues or recalls associated with it. Detail the troubleshooting steps you’ve already taken.
Breville can confirm whether you need a replacement part and guide you through any repairs. They may authorize shipping the machine to a service center if hands-on technical repair is required.
Consider Repairs vs. Replacement
If your Breville requires extensive repairs, evaluate the costs involved. Repair costs may start approaching the cost of a brand new machine. As home espresso machines age, replacement parts can become difficult to obtain too.
Compare the cost of repairs plus the machine’s age and condition to the price of a new purchase. This can help determine whether expensive repairs are worthwhile or if it’s better to put that money towards replacing the aging machine with a new one.
Conclusion
Lack of pressure on your Breville espresso machine can definitely be frustrating, but is usually fixable. In most cases, you can identify and resolve the cause with some DIY troubleshooting. Focus on common issues like blockages, water supply problems, improper coffee dosing, and lack of routine maintenance.
For tricky cases requiring specialty repair skills and parts, Breville’s customer support can provide technical guidance or authorized service. But take note of when repair costs start to exceed the value of the machine. Compare investing in repairs versus putting those funds towards purchasing a shiny new Breville model.
With some diligent troubleshooting and a willingness to properly maintain your machine, you can continue brewing café-quality espresso drinks at home.
