2) Function of Water level sensor
After supplying some amount of water through inlet valve and water level
sensor, the heater operates and steam generates. Generated steam is sprayed
by nozzle. If the water in the steam generator is reduced by spraying steam,
the water level sensor signals the board to refill the steam generator.
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.
