La Marzocco Technical Bulletin #41
New Steam Wand Assembly on GB/5s and FB/80s
Dear La Marzocco Family Member,
Herewith we would like to inform you about the latest modifications on our machines:
1) Beginning with machine SN# 2487, ALL GB/5 and FB/80 models will be equipped with a new steam wand
valve assembly, inclusive of a built-in anti-suction valve. SEE IMAGE BELOW
This feature will avoid the milk suction effect caused by a pressure drop in the boiler occurring after the
frothing phase. The anti-suction valve will automatically divert the milk drops sucked through the wand and
discharge them into the drain box.
Furthermore, the new and particular shape of the steam valve body (A.1.001.01) allows you to grasp it easily
with a wrench in order to unlock the steam wand adaptor (A.1.005) and change the wand effortlessly.
