5.10 NTC temperature sensor integrated in the heating element
5.10.1 General characteristics
In the electronic models an NTC sensor is used to control the washing temperature. In these sensors, the
internal resistance decreases as the temperature increases. This reduction in resistance is detected by the
electronic control system which, when the desired temperature is reached, disconnects the heating element.
