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.

When an error occurs, this function starts to keep generating error melody sounds and displays error indicators as
shown in the followings per corresponding error by blinking in 0.5sec interval until the error status is completely cleared out.
In this case, all the driving devices are turned off until the error is cleared out.

1. WATER SUPPLY ERROR

- Display shows such as fig. 1

- Water Supply Error occurs when water level frequency does not show
changes more than 100Hz or water is not supplied
up to the water level presetting for 20 min or more at the time of initial
water supply.

-The error status can be cleared by turning POWER S/W OFF and
resuming the POWER ON initial status.

2. WATER DRAIN ERROR

- Display shows such as fig.2

- In case the water level frequency is 24.5KHz or less in the initial phase
of UNB-detecting cycle.

- Water Drain error can be cleared by turning POWER S/W OFF and
resuming the POWER ON initial status.

3. OVER-FLOW ERROR

- Display shows such as fig.3

8. Trouble Diagnosis

- As the micom wash machine is configured of the complicate structure, there might be the service call.
Below information is prepared for exact trouble diagnosis and suitable repair guide.

Caution for the Repair and Replacement

Please follow below instruction for the trouble diagnosis and parts replacement.

1) As some electronic components are damaged by the charged static electricity from the resin part of wash
machine or the human body, prepare the human body earth or remove the potential difference of the
human body and wash machine by contacting the power supply plug when the work contacting to PCB is
executed.

POWER SUPPLY PLUG

2) Since AC220~240V is applied to the triac T1 and T2 on P.C.B, the electric shock may occur by touching
and be careful that the strong and weak electricity are mixed.

3) As the P.C.B assembly is designed for no trouble, do not replace the P.C.B assembly by the wrong
diagnosis and follow the procedure of the trouble diagnosis when the micom is not operated normally.

- Is the connection and operation of the pressure switch normal?

• If above points are not found, the PCB assembly is out of order.
Replace it.

- Is the connection and operation of the pressure switch normal?

- Is the pressure switch hose damaged so that the air is leaked?

- Is the pressure switch hose bent?

- Check the operation of the water level switch.

• If above points are not found, the PCB assembly is out of order.
Replace it.

The drum does not rotate during

4

washing.

The drum rotates by one direction

5

during washing. (The drum rotates
to one direction for SPIN.)

6 Drainage problem.

7 Dehydration problem.

8 Abnormal noise during SPIN.

Leak breaker or current/leak

9

breaker is down during washing.

10 The heating is not executed.

- Is the belt connected well?

- Is the winding of the motor continuous?
(Rotor winding, stator winding, generator)

- Is the motor protector normal?

• If above points are not found, the PCB assembly is out of order.
Replace it.

- The PCB assembly is out of order. Replace it.
(Inversion relay open trouble)

- Is the drainage hose bent?

- Is the winding of the drainage pump continuous?

• If above points are not found, the PCB assembly is out of order.

Replace it.

- The unbalance is detected.

- Put in the laundry uniformly and start again.

- Is the pulley nut loosen?

- Is the transport safety device removed?

- Is the product installed on the level and stable place?
(Little noise may be generated during the high-speed SPIN.)

<When the leak breaker and current breaker is installed separately>

- When the leak breaker is down, check and make the earth of the outlet.

- When the current is down, the current is leaked.

<Is the breaker down when the leak/current breaker is combined?>

- Check the rated capacity of the current and leak breaker.
The current breaker may be down due to the lack of the current when the
wash machine and other apparatus are used.

In this case, execute the cold water wash to check whether the current capacity is lack.

- Is the wash heater terminal unplugged?

- Is the wash heater normal?

- If above points are not found, the PCB assembly is out of order.
Replace it.
