Inspect the Heating Element
Accessing and inspecting the heating element involves unplugging the machine, removing the top or side panels, and visually checking for damage or corrosion. If you notice any broken wires or corrosion, the heating element may need replacement or professional repair.
Test the Thermostat
The thermostat regulates the temperature. If it’s defective, it may prevent the machine from heating even when power is present. Use a multimeter to test for continuity; if it shows no continuity when the machine should be heating, the thermostat is faulty and should be replaced.
Address Scale and Mineral Buildup
- Descale your Breville Bambino Plus regularly using recommended descaling products or tablets.
- If descaling doesn’t resolve heating issues, internal mineral deposits might be interfering with the heating system, requiring professional cleaning or repair.
Perform Routine Maintenance
Regularly clean the water filter and replace charcoal filters as needed. Use official cleaning tablets to keep the machine free of coffee oil and residue, maintaining optimal performance.
