Step 1: Turn Off and Unplug the Machine
Before performing any maintenance, ensure your Breville Bambino Plus is turned off and unplugged. Allow the machine to cool down if recently used, especially around the grinder area.
Step 2: Clear the Bean Hopper and Remove Grounds
- Open the bean hopper lid and remove any remaining beans.

This helps dissolve residual oils and clears minor blockages.
Step 6: Reassemble and Test
