I tried a search on storing coffee machine, but I probably am not clever enough to use the right terminology.

I want to put my Super Domobar in Storage for a long run, and wanted any advice ? Do I need to empty the boiler completely or turn it on once a month or something ? Any advice greatly appreciated

Thanks Dan

Its what I thought. I will have to drain to do it properly

I did the lay it down on the Tea Wand side.

I tilted the machine lying it completely down on the right side where the tea wand is. Opened the Tea Wand valve and all the water in the boiler came pouring out. Just the fact that at the other end the tubes that suck up the water from the Reservoir were "higher" than the Tea spout was enough to let the airway open I guess.

So it was not necessary to open any part of the boiler for an airway !!

I only used the DB for 5 months with 30ppm water, so I'm thinkin not that much about descaling.....

This is pure speculation, as I've never stored an espresso machine.

It maybe well to open the steam and hot water valves so the seals are not pressed against the seats.
It may also be well to move the lever to mid point, relaxing the tension on both upper and lower group spring sets.
