Most machine failures are caused by lack of cleaning and many manufacturer warranties do not cover cleaning related breakdowns, so it is important to keep a regular maintenance schedule. Listed below is a suggested maintenance schedule for most Prosumer espresso machines:

Grouphead Cleaning
The grouphead should be taken apart on a monthly basis to remove scale buildup, remove coffee residues, and improve shot flavor.
