Which step is NOT part of packing up a coffee machine?

The step that does not belong in the process of packing up a coffee machine is pouring fresh coffee grind into the dosing chamber. This action is typically associated with preparing the machine for immediate use rather than packing it up. When packing up, the focus is on cleaning and ensuring that the machine is properly maintained for future use, rather than preparing it with new ingredients.

The other actions—dusting the group heads, running water through the steam wand, and storing any remaining milk—are all critical components of the cleaning and maintenance process after a shift or service. Dusting the group heads helps keep the machine clean and prevents coffee residue buildup, running water through the steam wand clears any milk residue, and proper milk storage is essential for food safety and quality control. Thus, pouring fresh coffee grounds does not fit into the packing up process.
