G1000 / G2000 Dishwashers
4.3.3
Heating
A ring heater element in the circulation pump housing heats the water. The heater
element and circulation pump together form one component. This ensures that on
models with spray arm alternation, heating can always be carried out whichever
water path is currently being used.
Integrating the heater element in the pump housing also ensures that it is always
cooled sufficiently thus preventing the baking-on of soil particles or impurities in the
water.
Various safety measures protect the heater element against overheating, such as the
following:
Heater Pressure Switch
NTC Temperature Sensor
Electronic Control
The heater is only activated when the circulation pump has taken in sufficient water.
4.3.4
NTC Temperature Sensor, R30
An NTC sensor is fitted in the sump and monitors water temperatures during
dishwashing.
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, 6.8.15.
If during heating the desired temperature is not reached in the given time, a fault is
registered, see F25, 6.8.12.
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, (NTC short-circuited), 6.3.12 or Fault code F02, 6.8.12.
