LUCCA A53 Mini / Mini Vivaldi: OPV / Steam Gauge Fitting LeakUpdated 5 months ago

Before attempting this we recommend unplugging the machine and allowing it to fully cool off. Also, before beginning you will need to remove the panels from the machine.

Tools required:

• adjustable wrench
• 17mm wrench
• teflon tape

At this point you may be able to skip to the last photo and just tight down the nut sealing the elbow to the boiler. If the machine heats up and continues leaking though you will need to follow all the steps to clean the connection points of the fittings and create a better seal.
