2. Safety Devices
※
We adapt 5 safety devices for users to use this wash machine safely.
1) Balancing device (ASSY-Main PCB)
→
When the laundry is out of balance, to prevent the noises and vibrations, the unbalance
detecting sensor helps the laundry laid even and continue the dehydating process.
2) Anti-over water supply device
→
Because water supply value is broken, once water is supplied to the 2/3 level of the door, the
water supplied is drained automatically, Over -flow error is displayed on the panel
3) Temperature-regulating device(thermistor)
→
To prevent over-heating over the temperature setted up, THERMISTOR senses the temperature of
the machine continuously and helps the wash machine to work at the temperature given by users.
4 Overheating- controlling system
→
Under the circumstances of THERMISTOR inferiority or abnormal condition, if wash-heater is
overheated, automatically, assy -thermal fuse cuts off the power supply to protect the machine to
keep it safe.
5) Delicate clothing safeguard function(ASSY-Main PCB)
→
To protect the clothings which is weak to high temperature, the wash machine senses the
temperature inside the washing tub. if the temperature rises over 50
℃
wool washing course and
Delicate washing course display abnormal water temperature on the panel , after draining the
water.

6) Fuzzy washing function ( weight-sensing)
☞
After finishing initial water supply, when the fall of the water level needs supplementary water supply,
Sensing function perceives the weght with the supplementary water supply numbers and starts to work.
Under the course of Cotton, if the supplementary water supply numbers become 3 - 4 times the
function is going at default condition ( high water level ), if 1-2 below that is going at middle level, if 0 below
low water level, heating hours and rinse hours depend on the above data.
※
After sensing weight, above hours is decreased from above default hours
7) Bubble -detecting function
At the each condition of washing&dehydrating , rinse&dehydrating , hydrating, bubble -detecting function works,
this function works 5times normally, if the function detects bubbles at 6 times , the bubble-detecting function
stops and go on to the next process.
