What the exact symptom tells youThe exact display or behaviour is a diagnostic clue, not proof that a pump, grinder, heater or control board has failed.

4 checks for Bosch VeroCup 100 TIS30129RW, starting with Confirm the model and symptom

  1. Confirm the model and symptom

    On Bosch TIE and TIS coffee machines, “little or no crema” should be checked with the official user procedure before any part is considered.

  2. Make the machine safe

    Stop the drink, switch off, unplug where accessible and let hot water, steam and metal parts cool. Never open the housing, bypass an interlock or put fingers into a grinder.

  3. Apply the official check

    Compare fresh beans, a slightly finer setting and one identical dose; change only one variable and wait until the next cup for the grinder change to take effect.

    Crema that returns with fresh beans or a small grind correction is a preparation issue; no improvement across controlled tests merits service.
