Steam Boiler Maintenance

LUCCA A53 Mini / Mini Vivaldi: Vacuum Breaker

Below are instructions for how to remove the vacuum breaker from your LUCCA A53 Mini or La Spaziale Mini Vivaldi espresso machine. This is useful for when the vacuum breaker doesn't create a good seal and is constantly leaking steam.

 

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

Tools required:

  • phillips screwdriver
  • metal brush
  • 19mm long socket & socket wrench

To access the vacuum breaker you need to remove the top panel.

Once the vacuum breaker is removed be sure to clean off the top of the boiler where the vacuum breaker sits and clean off the cup the vacuum breaker sits inside so that when installing a new vacuum breaker you can create a proper seal.
