Abstract

A method for controlling heating processes in a coffee machine which is particularly suitable for preparing coffee on the basis of coffee pads. The coffee machine comprises a continuous flow heater and a pump used to convey water through the continuous flow heater. According to the inventive method, the temperature is measured in the region of the continuous flow heater and/or water which is conveyed by the pump. In order to avoid steam overpressure and to ensure a sufficient, constant temperature during the entire steeping process, the amount of water which is conveyed by the pump is influenced according to temperature. The invention also relates to an electronic control device.
