Abstract
An apparatus for preparing beverages, such as a coffee brewer, has a device for measuring the periods of time during which the heating element is switched on and off by a thermostat connected in series with the heating element. The ratio between the on period and the off period is computed. If the off period is smaller than the on period, an indication is given that there is scale deposit in the water pipe. If the off period is greater than the on period, an indication is given that brewing has finished and, optionally, the heating element may be switched off permanently.
