Why is my coffee machine making noises?

by Paul Sadler

  • Unusual noises from a manual Italian coffee machines with an E61 group is usually a sign of the group running dry. ie, without enough lubricant.

  • If you are handy and willing, take a look on YouTube and you will find plenty of step-by-step videos that show you how to disassemble and re-lubricate your espresso machine’s E61 group. All you will need are some basic tools and some food safe grease.

  • If you don’t want to get your hands dirty take it to a local Italian coffee machine technician for a quick, basic service. It won’t cost much.

  • Why does this sometimes happen earlier than expected? A simple reason. Too much back flushing with back flush detergent. Back flush detergent dissolves not only coffee oils, it also dissolves the good lubricating grease in the E61 group.
