摘要：
In order to provide in a simple way a household appliance, operated with water with a sensor (10) for contaminations of a circulated cleaning fluid, said sensor being composed of an element (11) transmitting optical signals and of an element (12) receiving optical signals, in which appliance erroneous measurements of the sensor (10) for contaminations of a circulated cleaning fluid are avoided, according to the invention the sensor (10) is arranged in a flow heater (1).
