Heater Element

Water heating is carried out by a ring heater element in the circulation pump
housing. 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. The heater rating is 1.30 kilowatts at 120 volts.
Various safety measures protect the heater element against overheating,
such as the following:
 Heater pressure switch
 NTC temperature sensor
 Electronic control
The heater is activated only when the circulation pump has taken in sufficient water.

Heater Pressure Switch, B1/13

Heater pressure switch B1/13 is located directly on the circulation pump and
registers the water pressure when the pump is in operation.
