NTC Temperature Sensor R30

Temperature sensor R30 (NTC resistor) is located in the bottom area of the
sump. The electronic constantly monitors the current wash water temperature
via the resistance of this sensor.
If the maximum safety temperature of 194°F at the NTC sensor is
exceeded, the program is interrupted (boiling prevention) and fault code
F26 is registered; see Fault Code F26, Section 080-3.22.
If the sensor or its connections are open- or short-circuited, the heating is
switched off. The program then continues to the end without heating or
dispensing; see Fault Code F01, Section 080-3.11 (NTC short-circuited),
or Fault Code F02, Section 080-3.12 (NTC open-circuited).
If, during heating, the desired temperature is not reached in the given
time, a fault is registered; see Fault Code F25, Section 080-3.21.
