2. Safety Devices
※ We adapt 5 safety devices for users to use this wash machine safely.
1) Balancing device (ASSY-Main PCB)
→ When the lauandry 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 valve is broken, once water is supplied to the 2/3 level of the door, the
water supplied is drained automatically, Over -flow error (E3) is diplayed 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.

power off for you if you do not re-select the course button or manual button
2) Door open function
● If door is open during the operating, all operating is halted, and door error message will be displayed (2-digit
panel displays "Ed" 4-digit panel displays "door") and error melody will coming out
● Door open error can be cleared by closing the door. the operating keeps going on
3) Rinse hold function
● If rinse hold function selected, the operating is finished , the machine do not drain the water after last rinse
4) No spin function
● If no spin function selected, the operating is finished after last rinse
5) Drain function
● Drain function is over, after pumping out the water for 2 minutes , without motor rotating
6) Pre-washing function
● Pre-washing function can be selected ,when you choice the following mode; cotton, coloreds, sythetics, delicates,
baby cotton
● Water level/reverse time is the same with the selected course
● Pre-washing takes about 15 minutes
7) Rinse+ function
● This function practises rinse process once more

8) Power-out compensation function
● If power is out on selected process, the process before power out is stored to EEPROM, once power is back
the process before power out continues.
● When power is back, washing process starts from the process at the point of the power out, rinse/drain process
starts from the initial process.

9) Water heater Error function
① This function starts working, when the heater works abnormally.
(this function begins sensing the heater 2 minutes later, after the heater operating)
② The value of the initial thermistor(A1) is compared with that of the thermistor(A2) in 2 minutes (Y=A2-A1)
- For 10 minute the variance of temperature(Y) is less than 2℃ "E5"message is displayed on the panel.
③ The value of the initial thermistor(A1) is compared with that of the thermistor(A2) in 11 minutes (Y=A2-A1)
- For 1 minute the variance of temperature(Y) increases more than 7℃(0.3V) "E6"message is displayed on the
panel.
④ At this time heater, Error "E5 (heater do not work), E6(overheated)" is displayed and all working process off
⑤ The heater operating continues during heating hours, if washing hour is left over, the residual washing process
keeps going without heating.

5. Main function
10) 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 weight with the supplementary water supply numbers and starts to work.
Under the course of Cotton, or Coloureds, 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.
ECO PRE mode is selected, the process going on at default condition.

11) 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.
● The bubble-detecting function during washing & dehydrating to rinse & dehydrating
after 2 times instant dehydrating and before main dehydrating, if the water level is under 25.45KHZ, Bubble
→ Detecting function thinks there are bubbles and add the bubbles-removing rinse, needing hours are above
hours and 8 min 40 sec.
→ The bubble-detecting function during single hydrating process
after 2 times instant dehydrating and before main dehydrating , if the water level is
25.45KHZ below or
during main dehydrating, water level data is 23.80KHZ below Bubble-detecting function thinks there are
bubbles and add the bubbles-removing rinse 1 times, needing hours are above hours and 5 min 55 sec.

12) Unbalance detecting & laundry balance positioning system
① Just before the hydrating process and just after reversal rotation for balancing laundry position, this function is
carried out
② The initial 6 sec is the period of reversal rotation for balancing laundry position , Drum rotates 50rpm for
initial 6 sec
③ Next 10 sec, the rotation increases the speed from 50 rpm to 90 rpm slowly
④ During the next 18 sec, drum rotates at the speed of 90 rpm,
the sensor decides the degree of laundry
unbalance with TACHO data which is attached to motor
⑤ If the degree of unbalanced laundry is over 6 times to default value, laundry balancing system carries out
feed back process 6 times

13) R.P.M control
The rotating motor enables the magnetics( i.e generator) to generate magnetic flux in proportion to r.p.m,
magnetic flux induced by coil sensor in the opposite side produces the wave like the figure below to dΦ/dt and
via rectangual wave generating citcuit, the waves reaches MICOM and micom controls r.p.m with the pulse,
count and cycle inputted by program.
