Preserve the exact words, code, timing and drink before changing anything: a similar symptom can have a different cause.

Do not order a pump, grinder, valve, heater or control board from this symptom alone.
Before checking Miele CVA 7845 DirectWater
- Keep hands clear of hot water, steam, the grinder and moving brew mechanisms. Switch off and unplug before removing a user-removable unit, and never open an electrical, boiler, pump or grinder cover.
