5.12 NTC temperature sensor (incorporated in the heating element)

5.12.1 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.
