[tech] Coke machine fault, was Re: [ucc] Minutes of Meeting on 14th July 2020

[James Arcus]

The machine has been left off.

I'll be in over the next couple of days, so can poke around for info. 
But I don't want to do too much touching of the electronics. What's the 
best way to go about emptying it whilst powered off?

Cheers,

James [MPT]
