hi coffee snobs
im currently in the process of re building my LA DORIO machine , and was wondering why do most older machines have a hole in the front fascia , tried to post a pic but failed sorry.
its between the the two pistons and centre of the machine behind the drip tray.
i cant see any practical use for it.
It's most likely the port for checking the flame height on the gas burner.
Java "Old what?" phile
