The TIU20508 comes in dark silver and measures just 9 3/4 inches across. It belongs to the 300 Series VeroCafe family and serves espresso, cappuccino, latte macchiato and milk foam. Households buying their first bean-to-cup machine often choose this tier, and the advice that prevents the most service calls has nothing to do with coffee.
It concerns water. Heating it over and over each day makes a machine scale up much faster than a kettle does, especially where the supply is hard. Filtered or softened water protects the heating circuit, whose performance falls as scale builds, and it stretches the time between descaling cycles.
The milk frother is the other weak spot, and it clogs without regular rinsing. The brew unit comes out for cleaning and the grinder uses ceramic discs. We start with the water: what comes from your tap, and when the machine was last descaled. Then we test the heating circuit and the frother.
Quite a lot. Because the water is heated again and again, hard water coats the heating circuit with scale sooner than owners expect, while filtered water clearly stretches the time between descalings.
Usually not advised. Certain machines depend on some mineral content so their water sensors read correctly, so follow the water guidance in the Bosch manual.
Rinse it after each milk drink and run the cleaning program when prompted. Milk dries fast inside narrow passages, and regular rinsing prevents a blockage that would need a visit.
