IMPORTANT: We don’t yet know if this is a one off glitch or common to all machines.
This is probably of interest to anyone who has competed or watched competitions since 2005.
In some competitions the La Marzoccos used were GB5 and FB80 AV machines – meaning they have a line of buttons linked to volumetric controls. More recently a lot of machines just had one big on/off button.
Anyway – I remember back in 2005 in Seattle and in other barista competitions that during a competitors set the machines just seemed to switch off. Everyone was very confused how a barista could have done this as you have to push and hold an on/off button for at least 3 (or maybe 5) seconds.
A few months ago Matt Buckley at Milk Bar showed me this weird little thing (he didn’t want to be in the video). Here is an explanation:

If anyone else can verify this bug I’d be interested/grateful and also I’d like to know if it affects 2 groups too. Comment away!

In the event that a machine did this during a competition what was the protocol? Did the competitor just have to lump it and carry on, or were they allowed to restart?

competitors are allowed to call a “technical,” which will pause their clock until the issue is resolved. kind of a “time-out.”
the rules should be somewhere online, probably at any of the SCA sites.

I wouldn’t be so sure that its a bug. Its probably just a back-up in case something happens to the real on/off switch that prevents you from switching the machine on/off. And if it isn’t, La M will say it is ;)

There is a normal button push on/off as well as a main switched on off already. It seems weird to be able to completel switch off a machine by just mispushing two buttons for a split second.

I’d agree that she fact that its only a split second that you need to hold it for suggests that it wasn’t planned. Have LaM anything to say about it?

It seems this is a known bug in Australia. i tried it on a 2 group gb5 and a 4 group and both machines were responsive to the bug. When I asked the boss, he mentioned that EES had already notified him of it.

I’ll verify this as well… surely odd.

Confirming the same thing for the grouphead with the ON/OFF button on a 4grp FB80. I switch it off in this manner at least once a month… and of course only when the queue is at least 10-deep.
