Step 2: Reset the Machine
Sometimes, a simple reset can resolve temporary electronic glitches. Turn off the machine, unplug it from the power source, and wait for about 10 minutes. Then, plug it back in and turn it on. Observe whether the heating indicator lights up or if the machine begins to heat.
Step 3: Check for Scale Buildup and Descale
Mineral deposits can insulate the heating element, preventing proper temperature regulation. Use a descaling solution compatible with your Breville Bambino Plus to clean the internal components:
- Follow the manufacturer’s instructions for descaling, typically involving running a mixture of descaling solution and water through the machine.
- After descaling, run plain water to rinse out any residues.
- Regular descaling (every 1-3 months depending on water hardness) helps maintain optimal heating performance.
Step 4: Inspect Internal Components
If descaling doesn’t resolve the issue, the problem may lie within the machine’s heating element or temperature sensor. However, opening the machine involves risks and should only be done if you’re comfortable with electrical repairs:
- Unplug the machine and allow it to cool completely.
- Remove the outer panels carefully following the manufacturer’s instructions.
- Visually inspect the heating element for visible damage or corrosion.
- Check connections and wiring for loose or burnt-out wires.
Step 5: Test and Replace Faulty Parts
If you suspect the heating element or sensor is faulty, testing with a multimeter can confirm issues. Replace defective parts with original Breville-compatible replacements. If you’re unsure, it’s best to contact a professional technician for repairs.
Tips and Warnings
- Always unplug the machine before opening or working inside it to prevent electrical shock.
- Use only manufacturer-approved parts for replacements to avoid damage or voiding warranty.
- Regular maintenance, including descaling and cleaning, extends the lifespan and ensures proper heating.
- If your machine still doesn’t heat after these steps, professional servicing is recommended.
