Bosch TIU20508

Model # TIU20508

The TIU20508 is the dark silver 300 Series VeroCafe, compact at 9 3/4 inches wide with the standard five-drink list. Entry-tier bean-to-cup machines are the ones most often bought by households new to the format, and the advice that saves the most service calls is about water rather than coffee: use filtered or softened water if your supply is hard, because scale accumulates in a machine that heats water many times a day far faster than in a kettle.

FAQ

Bosch TIU20508 FAQ

On a machine that heats water many times a day, a great deal. Hard water scales the heating circuit far faster than most owners expect, and filtered water noticeably extends the interval between descaling cycles.

Bosch specifies what is suitable in the manual, and distilled water is generally not recommended - some machines need a minimum mineral content for their water sensors to work correctly.
