9-6. HEATER ASSEMBLY

1. The Wash Heater is designed to raise the wash water to the desired temperature

selection during certain wash cycles.

2. The Steam generator heater is designed to make the water to the steam during

steam cycles. 

* Each circuits of loads in wiring diagram are all same.

After supplying some amount of water through inlet valve and water level
sensor, Heater operates and steam generates. Generated steam is sprayed by
nozzle. If the water in the steam generator is reduced by spraying steam, water
level sensor decide to supply water or not.

The Steam Generator Assembly is supplied as an assembly only; parts like the
water level sensor, thermistor, or heater cannot be replaced individually.
Diagnosis is limited to determining malfunction and replacing as an assembly.
The steam generator does not have to be removed from the machine to be
drained. Be sure to let the water cool to avoid a burn. Have a hose available to
slip onto the connector or a large towel to catch the water so it doesn’t run
down into the machine cabinet. If you remove the steam generator before
draining it,  be sure to avoid tipping it and spilling the water.

It is the part of sensing water level. It decides to supply water or not when the
steam generate. (to protect heater)
