10.8. Hot Water Wand and Steam Wand
The tip of the Hot Water Wand is removable and can be cleaned after removing it from the machine. It
simply unscrews, but do not use pliers or other similar tool that may mar the finish. A small strap wrench
is preferable if a tool is needed.
Here is an image of the parts disassembled so you can see how they go back together. Note the black
O-ring still on the wand. Be sure it is there when reassembling. All parts are shown here with the correct
side facing upwards, and in order of assembly, starting with the part on the right.
The Steam Wand can become clogged if a cleaning is missed after steaming milk. The tip can be
removed by unscrewing. Remove the tip and soak it in cleaner, overnight if necessary. Note the O-ring. It
fits in the slot of the tip. Be sure the O-ring is used when assembling.
10.9. Long Term Storage
The boiler and heat exchanger contain water. Because of that, if your Vibiemme Domobar is not going to
be used for a while or is being placed into storage, some factors must be considered.
The first is temperature. If it can be avoided the machine should never be stored where it will be subjected
to freezing temperatures. If water in the machine is allowed to freeze, a lot of damage can be done as the
water expands when it turns to ice. Try to avoid damage by freezing.
Although there are steps that can be taken to remove some of the water in the boiler, heat exchanger,
brewhead, and all the pipes and hoses, it is very difficult to get all the water out. If you suspect that your
Vibiemme may be left where it could be subjected to freezing conditions, check with your local RV supply
store. They sell antifreeze chemicals designed to be used in drinking water systems. Be sure that the
additives are safe to use on brass, copper, plastic, and chrome parts. Follow the instructions precisely.
After treating with these chemicals, tape over the power plug and tape a note to the machine and the
power cord at the plug end warning of the addition of these chemicals, and add a warning to completely
flush the machine before use! Be sure to completely flush the system before energizing the heating
element when putting the machine back into service.
WARNING: Neither damage from these sorts of chemicals nor damage from freezing are covered
by the warranty. Use of these chemicals and storage in freezing conditions is to be done at your
own risk.
When placing a machine back into service after storage, even if not stored in such extreme conditions as
mentioned above, you must flush out the machine with fresh water to remove any stale water that was
left in the boiler, the heat exchanger, and in the various pipes and hoses. To do so:
1 - First wash the Water Reservoir, then fill it with water.
2 - Turn the Power Switch to position I. After the initial cycle of the pump stops, turn the Power
Switch to position II and wait for pressure to build in the boiler.
3 -When the boiler pressure is at or above .5 bar, open the Hot Water Valve and pump about 6 ounces
of water into an appropriate vessel. Repeat that four times, waiting between glasses for the pump to stop
which signifies that the boiler has been refilled.
4 - Now pull three or four double shots without using coffee, then do a clean water backflush.
5 - Check the reservoir water level (unless plumbed-in).
6 - Allow the machine to fully warm up and you are ready, once again, to make espresso.
