LUCCA M58: Replacing Steam Boiler Element

Below you will find instructions for replacing the steam boiler element in a Quick Mill LUCCA M58 Espresso Machine.

Tools Needed:

  • 1 7/16" Socket + Impact Driver
  • Phillips Screwdriver
  • 7mm Crescent Wrench/Adjustable Wrench

1. Drain the boiler of the machine.

2. With the bottom panel removed, you will have access to the boilers. If the machine is laying on its right side, the element for the steam boiler will be up higher. It has a third wire coming out of it as well if you can't tell the difference between the two elements.
