Description
The thermostat monitors the temperature while
the machine carries out a program. The heating
element contactor is controlled using open and
closed contacts.
The thermostat sensor is located at the lowest
point of the outer drum to the left of the heating
element. A liquid-filled cable (capillary tube) runs
from the sensor to the thermostat, located in the
automatic control unit. The water temperature
controls the liquid expansion and thereby the
activation of the various thermostat contacts.
Temperature selection (contact selection) (90
