LUCCA A53 Mini / Mini Vivaldi: Replacing Safety Valve

Below you will find instructions for replacing the 3/8" safety valve on the La Spaziale LUCCA A53 Mini espresso machine.

Tools Needed:

• Phillips Screwdriver
• 2 Adjustable Wrenches
• New 3/8" Safety Valve

NOTE: New model Lucca A53 and La Spaziale S1 machines come equipped with an updated safety valve. These new valves look different, but they are functionally identical.

1. Remove the panels of the machine

2. The safety valve is located behind the water tank.

3. Using 2 wrenches, hold the top nut in place and remove the safety valve with the second wrench.

4. Before installing the new safety valve, wrap the threads with PTFE tape to create a better seal.
