Steam & Steam Boiler Maintenance

LUCCA M58: Cleaning fill probe

Below are instructions for cleaning a fill probe on a Quick Mill LUCCA M58 espresso machine. This is useful if the steam boiler looses pressure quickly from scale build.

Before doing this we recommend unplugging the machine and allowing it to fully cool off. Tools required:

  • adjustable wrench
  • wire brush

First, remove the panels.

Reassemble the machine, draw 4 oz of water out of the steam boiler, allow it to reheat and test for pressure retention.
