7.3. Minimizing Mineral Buildup
Mineral buildup in the boiler can be minimized by using the proper quality water and by de-scaling as
mentioned in the general instructions. Another way to lessen this scale accumulation is to pump water
out of the boiler occasionally.
This is particularly important if you rarely use the hot-water function of the Vibiemme Domobar. To refresh
the water in the boiler, simply place a heat-resistant vessel under the hot water wand and open the valve.
Dispense about 6 ounces, and then allow the boiler to refill before proceeding. Repeat this two or three
times. Doing so every one or two weeks will help minimize scale build up.
