HarveyMushman It’s not really easy/possible on the Linea Mini as it won’t let you run the reservoir dry due to the low water cutout.
You really don’t want to do that. It will be a pain to prime the circuit :-), let alone other potential problems.
For 10 days? I wouldn’t bother, personally. I’ve been away for 3, 4 weeks before. Never took any action, apart from giving it a good water refresh when I turned the machine on again (wash tank, recycle water in boilers, etc). I wouldn’t worry leaving the machine alone for 10 days, at all.
