Ensure Proper Power Supply and Basic Checks
- Verify that the espresso machine is properly plugged into a functioning power outlet. Test the outlet with another device to confirm it’s working.
- Check that the power switch on the machine is turned on. Sometimes, the switch may be loose or not fully engaged.
- Inspect the power cord for any visible damage or frays. Do not attempt to use the machine if the cord is damaged—replace it or seek professional repair.

Perform Basic Cleaning and Descaling
Mineral buildup can interfere with the heating element’s function. Regular cleaning and descaling help maintain optimal performance.
- Turn off and unplug the machine before cleaning.
- Remove and clean the water reservoir. Use fresh water and a mild descaling solution if necessary.
- Run a descaling cycle using a descaling solution suitable for Breville machines, following the manufacturer’s instructions.
- Clean the shower screen, filter basket, and other removable parts with a soft brush or cloth.
This process can remove mineral deposits that cause the heating element to malfunction.
Test the Heating Element and Thermostat
If cleaning doesn’t resolve the issue, the problem may be with the internal components such as the heating element or thermostat.
- Unplug the machine and open the casing carefully, following your model’s service manual or a repair guide.
- Locate the heating element and thermostat—these are usually accessible once the casing is removed.
- Use a multimeter to test for continuity. If the heating element shows no continuity, it needs replacing.
- The thermostat should also be tested; if it’s faulty, it will need replacement.
Note: If you’re not experienced with electrical repairs, consider consulting a professional technician to avoid injury or further damage.
Replace Faulty Components and Reassemble
Once you identify faulty parts, replacing them is often straightforward but requires caution.
- Order genuine replacement parts, especially the heating element or thermostat, compatible with your Bambino Plus.
- Follow your service manual or online repair guides to remove and replace the defective components.
- Ensure all connections are secure and there are no loose wires.
- Reassemble the machine carefully, making sure all screws and panels are properly in place.
After reassembly, plug in the machine and run a test to see if it heats correctly.
Consult Professional Repair Services
If troubleshooting and replacing parts don’t restore heating, or if you’re uncomfortable performing internal repairs, it’s best to seek professional help.
- Contact Breville customer service or authorized repair centers.
- Provide details about your issue and the steps you’ve already taken.
- Professional technicians can diagnose complex electrical issues and perform safe repairs.
Trying to repair electrical components without proper training can be dangerous, so prioritize safety and expert assistance.
