Check Water Level and Filters
Low water levels or clogged filters can interfere with the heating process. Remove the water reservoir and refill it with fresh, filtered water. Ensure the water level is above the minimum line.
Inspect the charcoal filters (if equipped) for clogs or buildup. Replace filters if they are dirty, as they can restrict flow and impact heating efficiency.
Inspect the ThermoJet Heating System
The Breville Bambino Plus uses an innovative ThermoJet heating system designed for fast startup. If the machine is powered but not heating, the ThermoJet might be malfunctioning or blocked.
Unplug the machine, then carefully remove the outer panels following the manufacturer’s instructions. Check for any visible damage or debris around the heating element. Do not touch electrical components directly.
Test and Reset the Thermostat or Fuse
If you are comfortable working with electrical components, use a multimeter to test the thermostat and thermal fuse for continuity. If either component is faulty, replace it with a genuine part.
Before replacing, reset the system by unplugging the machine for at least 10 minutes. This can clear any temporary faults or error states.
Perform Maintenance and Consider Professional Repair
Regular cleaning and descaling can prevent overheating issues caused by mineral buildup. Use recommended cleaning tablets, such as the Breville BEC250, to keep internal components clean.
If the machine still does not heat after these steps, or if you are unsure about handling electrical parts, contact a certified repair technician for diagnosis and repair.
