Step 2: Perform a Descaling Process
Mineral buildup inside the heating system can prevent proper temperature regulation. Descaling your Breville Bambino Plus can resolve heating issues caused by scale.
- Mix a descaling solution compatible with espresso machines, such as Breville BEC250 Cleaning Tablets or equivalent, following the product instructions.
- Fill the water reservoir with the descaling solution and run a descale cycle per your machine’s user manual.
- Ensure the machine heats up and runs the descaling solution through the system, paying attention to any error messages or irregular operation.
- After descaling, rinse thoroughly with clean water to remove residual deposits.
Step 3: Check and Reset the Thermostat
The thermostat regulates the heating temperature. If faulty or tripped, the machine may not heat properly.
- Unplug the machine and remove the outer casing with a screwdriver, following safety precautions.
- Locate the thermostat; in most models, it’s near the heating element.
- Use a multimeter to test the thermostat’s continuity. If it shows no continuity, it’s defective and needs replacement.
- Replace the thermostat if faulty, ensuring you use a compatible part specified for the Bambino Plus.
- Reassemble the machine and test if it heats up properly.
Step 4: Inspect and Replace the Heating Element
If the thermostat is functional, the issue might be with the heating element itself.
- With the machine unplugged, access the heating element by removing the casing.
- Test the element with a multimeter for continuity. No continuity indicates a broken element.
- Replace the heating element with a compatible model, following manufacturer guidelines.
- Reassemble and run a test cycle to confirm proper heating.
Step 5: Seek Professional Repair or Replacement
If after these steps your Breville Bambino Plus still does not heat, it may be time to consult a professional technician. Electrical faults, circuit board issues, or complex component failures require specialized skills.
Contact Breville customer service or an authorized repair center for further assistance. Sometimes, replacing the entire machine might be more cost-effective than extensive repairs.
