Inspect the Heating System and ThermoJet System
The Bambino Plus employs an innovative ThermoJet system for fast heating. If the machine isn’t heating, the issue might be with this system or its components.
- Unplug the machine and wait for it to cool down completely.
- Remove the water reservoir and inspect the area around the heating element for any visible debris or damage.
- Check for any blockages or mineral buildup that could interfere with the heating process.
- If you notice corrosion or damage, the heating element or ThermoJet system may need professional servicing or replacement.
Reset the Machine and Check the Thermostat
Sometimes, a simple reset can resolve heating issues. Also, the thermostat may have failed, preventing the machine from heating.
- Unplug the Breville Bambino Plus and wait at least 10 minutes.
- Plug it back in and turn on the machine. Observe if it begins to heat up.
- If it still doesn’t heat, locate the thermostat (if accessible) and test it with a multimeter for continuity. This step is best performed by a qualified technician.
Perform Routine Maintenance and Descaling
Mineral buildup and clogged filters can interfere with heating and overall performance.
- Remove and clean the water filter regularly, replacing it if needed. Use compatible charcoal filters for better water quality.
- Descale your machine using a descaling solution recommended by Breville or the cleaning tablets listed below. Follow the manufacturer’s instructions carefully to prevent damage.
- Regular cleaning ensures that mineral deposits don’t insulate the heating element, which can cause it to malfunction.
Replace Faulty Parts or Seek Professional Help
If your troubleshooting steps haven’t resolved the issue, some parts may need replacement. Common faulty components include the heating element, thermostat, or internal wiring.
Because working with electrical components can be dangerous, it’s advisable to contact a certified service technician or Breville customer support for repairs.
