Abstract
A coffee machine comprising an instantaneous electric heater for heating water, which is transported from a storage tank and conducted under pressure after the heating process into a brewing chamber to prepare the coffee, said chamber comprising an outlet nozzle for discharging the prepared coffee. The machine also comprises at least one sensor for recording an electric measured value that correlates to the temperature of the heated water and a control system for controlling the pump output of the pump and/or the heating output of the instantaneous heater in accordance with the measured value. The device permits a blockage of the nozzle to be identified and safely removed. The control system shuts off the pump output and/or the heating output if the measured value exceeds predefined thresholds and blocks a restart of the pump output and/or heating output for a specified blocking period by activating blocking elements.
