Ensure Proper Power Supply and Basic Checks
- Start by verifying that your Breville Bambino Plus is properly plugged into a functioning outlet. Test the outlet with another appliance to confirm it supplies power.
- Check the power switch on the machine — make sure it’s turned on. Sometimes, accidental switches can be turned off or not fully engaged.
- Look for any visible signs of damage or loose cords. If you notice frayed wires or damaged power cords, do not attempt to repair them yourself; consult a professional or replace the unit.
- Unplug the machine, wait about 30 seconds, then plug it back in. Sometimes, a simple reset can resolve temporary electrical glitches.

Inspect and Reset the Circuit Breaker
If your espresso machine still isn’t heating, check your home’s circuit breaker panel. A tripped breaker can cut power to the outlet.
- Locate your circuit breaker panel and identify the breaker associated with the outlet you’re using.
- If it’s in the off position or in a tripped state, reset it by switching it off, then back on.
- Test the outlet again with a small appliance or multimeter to ensure it now supplies power.
If resetting the breaker doesn’t resolve the issue, move on to inspecting internal components.
Test the Heating Element and Thermostat
The heating element is responsible for warming water in your Breville Bambino Plus. If it’s faulty, the machine won’t heat properly.
- Unplug the machine and remove the water reservoir and drip tray for access.
- Access the internal panel (refer to your user manual for specific instructions). Use a multimeter to test continuity across the heating element; if there’s no continuity, it’s defective and needs replacing.
- Check the thermostat and temperature sensors for proper operation. Faulty sensors can prevent the heating element from activating.
Note: If you’re not comfortable with electrical testing, consider contacting a professional technician.
Reset the Machine and Check for Error Codes
Many Breville espresso machines have internal safety features that prevent heating if certain errors are detected.
- Ensure the water tank is filled and properly seated, as some units won’t heat if water isn’t detected.
- Perform a reset by unplugging the machine, waiting 10-15 minutes, then plugging it back in.
- Check the display panel for error codes or blinking lights. Refer to your user manual to interpret these signals and follow recommended troubleshooting steps.
If error codes persist, the internal sensors or circuit boards may need servicing.
Perform Regular Maintenance and Descaling
Mineral buildup from tap water can cause overheating or prevent the heating element from functioning efficiently.
- Remove and descale the machine using a descaling solution recommended by Breville, or use a mixture of vinegar and water.
- Follow the descaling instructions in your user manual carefully, ensuring all residues are flushed out.
- Clean the water reservoir, filters, and steam wand regularly to maintain optimal performance.
Consistent maintenance helps prevent future heating issues and prolongs your machine’s lifespan.
