Do you mean when the coffee machine turns on and does the heating and rinsing and drains the water into the cup?
To do this, I designed a water outlet. When the coffee machine is turned on, it starts the washing stage and water flows through it into the cup if it is standing or is poured into the tray if there is no cup. The water drain removes water from the cup, preventing water from entering the cup during washing and the cup remains dry, all the washing water goes past the cup
