LG ( 6023C / 8023C / 1023C) SUPER-SLIM WASHING MACHINES
Triple Solenoid valve:
There is a triple solenoid valve to direct the water to the appropriate detergent drawer
compartment. Water flow is directed to the pre-wash drawer in Pre-Wash programs by pre-
wash valve, water is directed to the main wash detergent drawer in Main-Wash and Rinse
programs by main-wash valve. At the final rinse, water is directed to the softener drawer
by softener valve. There is a regulator inside the softener valve to reduce the flow rate.
Pressure Switch Sensor:
The output frequency of the sensor changes by the water level. The valves operate to
reach the required water levels. If pre-defined frequency level reaches, the valves close by
the PWB/controller.
Heater:
A 1450-watt heater is used. There are two thermo fuses on the heater. If the heater runs
without water inside the tub, the thermo fuse cuts off the line to protect the plastic tub
damages because of the over heating. The thermo fuses are not reusable. If the thermo
fuse cut off the line the heater should be change. Heater is controlled by a relay inside the
PWB.
Door lock:
PTC door-lock is used. When the door is closed, the PTC disk is heated up hence the door
is locked. After the program is terminated, the PTC is cooled down in max.70 seconds and
the door is released. Thus the door is prevented from opening during operation. The
machine does not operate when there is a problem with the door lock.
Pump motor:
It is a Mono-phase synchronous motor. Current is conducted from the program apparatus
at empty-water phase.
