11-2. TERMINOLOGY

1) ASSY-MAIN PCB (Imbalance Sensor)
→ To prevent the laundry from gathering on one side of the tube causing noise and vibration, the
washing machine uses an imbalance detection device that evenly disentangles the laundry before
the hydrating cycle starts.

2) DOOR-LOCK S/W

→ Prevents the door from being opened while a cycle is in progress. For safety purposes, it keeps
the door locked even in pause mode or after the washing cycle unless the water level frequency
is greater than 24.8Khz (anti-overflow level) or the inside-tube temperature is less than 65 ℃ in
the hydrating cycle, and 55 ℃ in the washing cycle.
3) SENSOR-PRESSURE (Anti Over-Flow)
→ When the water supplied is more than 2/3 of the tube capacity due to a malfunction of the water
supply valve, this device automatically starts water-draining and displays "OVER-FLOW
ERROR(E3)" on the LED.
4) THERMISTOR
→ Keeps sensoring and controlling the temperature inside the tube to keep it below your settings.
5) ASSY-THERMAL FUSE (Anti Over-Heat)
→ When the washing heater is overheated due to an error in the thermistor or any other
malfunction,
the assy-thermal fuse (built in the heater) is automatically activated to disconnect the power for
your and the product's safety.
6) ASSY-MAIN PCB (Sensitive Laundry Protection)
→ To avoid any damage to sensitive laundry, the tube temperature is detected and "ERROR(E8)" is
displayed on the LED for Wool or Lingerie courses when the temperature is over 50 ℃ .
7) THERMOSTAT (Anti Over-Heat)
→ When the heater (drier) overheats from an error in the thermistor or any other malfunction, the
thermostat (installed on the drying duct) is automatically activated to disconnect the power for
your or product's safety
8) CHILD LOCK
→ Prevents children from playing with the washing machine.
