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°C,
60°C, 40°C or 30°C) is controlled by the
programmer and the program selector.
Repair instructions
All thermostats are factory-set for the various
machines. As a rule, this setting should not be
changed. For that reason, the thermostats are
sealed with enamel paint.
N.B! The machine guarantee ceases to be
valid if the thermostat is tampered with.

Replacing the thermostat

• Remove the front panel and pull out the
thermostat sensor.
• Undo the capillary tube strapping and replace
the thermostat. Install the new capillary tube in
the same way as the old one.
