Check the Power Source and Basic Settings
- Ensure the espresso machine is plugged into a working electrical outlet. Test the outlet with another device to confirm it supplies power.
- Turn on the machine and wait for the power indicator lights. If there’s no response, check the power cord and ensure all connections are secure.
- Verify that the machine’s power switch is in the ‘On’ position and that the machine is not in standby mode.
- If your model has a display or indicator lights, confirm they are functioning properly. Sometimes, a simple reset by unplugging for 30 seconds can resolve minor electrical glitches.
If these steps do not resolve the heating issue, proceed to inspect internal components and cleaning routines.

Inspect and Clean the Water Reservoir and Filters
Mineral deposits and debris can interfere with the heating system. First, remove the water reservoir and check for any buildup or blockages. Rinse it thoroughly with clean water.
Next, inspect the charcoal filters (if installed). Dirty or clogged filters can restrict water flow, affecting heating performance. Replace filters as needed, using compatible options like the Breville Charcoal Filters or Possiave Water Filters.
Cleaning the machine’s shower screen and filter baskets with a dedicated espresso machine cleaning tablet (such as the Breville BEC250) can remove coffee oils and residues that may hinder proper water flow and heating.
Descale Your Espresso Machine
Mineral buildup inside the boiler or heating element can prevent the machine from reaching the correct temperature. Regular descaling is crucial. Use a descaling solution recommended by Breville or a compatible descaling product.
Follow these steps:
- Mix the descaling solution with water according to the manufacturer’s instructions.
- Pour the mixture into the water reservoir.
- Run the descaling cycle as per your machine’s user manual, ensuring you follow the recommended procedure for your model.
- After descaling, rinse the water reservoir and run several cycles with clean water to remove any residual descaling solution.
This process helps remove mineral deposits that can block heat transfer and reduce efficiency.
Test and Replace Faulty Components
If cleaning and descaling do not resolve the heating issue, the problem may lie with internal components such as the thermostat or temperature sensor. These parts regulate and maintain the correct temperature.
To test these components, you may need to access the internal parts, which involves removing panels carefully. If you’re not comfortable doing this, consider contacting a professional repair technician.
Replacing a faulty thermostat or sensor can restore proper heating. Use genuine replacement parts to ensure compatibility and safety. For example, parts like the thermostat or temperature sensor can be sourced from authorized suppliers or service centers.
When to Seek Professional Repair
If you’ve exhausted troubleshooting steps and your Breville Bambino Plus still isn’t heating, it’s time to consult a professional. Electrical issues or faulty internal parts often require specialized tools and knowledge to repair safely.
Contact authorized Breville service centers or qualified technicians for diagnosis and repair. Attempting complex repairs yourself can void your warranty or cause further damage.
Regular maintenance, including cleaning and descaling, can help prevent future heating problems and extend the lifespan of your espresso machine.
