1. Verify Power and Machine Settings
Start by confirming that your Breville Bambino Plus is properly plugged into a functioning outlet. Sometimes, the issue can be as simple as a loose power connection. Check the power cord for any visible damage. Next, ensure that the machine’s power switch is turned on, and the display panel indicates it’s active.
Also, verify that the machine is not in any standby or sleep mode. If your model has a temperature or heat indicator, ensure it is set to the desired temperature. Resetting the machine by turning it off, unplugging for a minute, then plugging back in can sometimes resolve minor electrical glitches.

2. Check the Water Reservoir and Filters
Insufficient water or clogged filters can prevent the heater from activating. Remove the water reservoir and inspect it for cleanliness and proper placement. Fill it with fresh, filtered water and ensure it’s seated correctly in the machine.
Next, examine the water filter (if installed). A clogged or old filter can restrict water flow and affect heating. If your machine uses charcoal filters or other water filters, replace them regularly—every 2 months is recommended—to maintain optimal performance.
Cleaning the water pathways and descaling the machine periodically can also prevent blockages that interfere with heating.
3. Inspect the Heating Element and Temperature Sensor
If the machine still isn’t heating, the issue might be with the internal heating element or temperature sensor. Accessing these components requires opening the machine’s casing, which involves removing screws and carefully disconnecting parts.
In your testing, look for signs of damage, corrosion, or mineral buildup on the heating element. If the element appears broken or burned out, it will need replacement. Similarly, a faulty temperature sensor can send incorrect signals to the control board, preventing the heater from activating.
Note: If you’re unfamiliar with electrical repairs, it’s advisable to have a professional handle this step to avoid risks.
4. Perform a Reset or Factory Reset
Many Breville models allow for a reset to clear errors and restore default settings. Check your user manual for specific reset procedures. Usually, this involves holding down certain buttons or unplugging the machine for a set period.
Resetting can clear minor firmware glitches that might prevent heating. After resetting, turn on the machine and see if it heats normally. If not, proceed with further inspections or professional repairs.
5. Consider Professional Repair or Replacement
If you’ve tried all the above steps and your Breville Bambino Plus still refuses to heat, it’s time to consult a professional technician. Internal component failure, like a broken heating element or control board, often requires specialized tools and knowledge to repair.
In some cases, replacing the heating element or other parts may be necessary. Contact Breville customer service or an authorized repair center for assistance. Remember, attempting complex repairs yourself can void warranties or cause further damage.
