No
Item
Cause and treatment
1
The power is not supplied
- Is the PCB connector connected well?
- Is the voltage normal?
- Is the power supply plug connected well?
- Is the noise filter connected well?
- Is the secondary output of the power supply transformation normal?
- Is the fuse disconnected? (option)
• If above points are not found, the PCB assembly is out of order.
Replace it.
2
The water is not supplied.
- Is the knob open?
- Did you push START/PAUSE button after selecting the course?
- Is the water supply valve connected well?
- Is the winding of the water supply valve continuous?
- 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.
3
The wash does not start though
the water supply is stopped.
- 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.
4
The drum does not rotate during
washing.
- 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.
5
The drum rotates in one direction
during washing. (The drum rotates
in one direction for SPIN.)
- The PCB assembly is out of order. Replace it.
(Inversion relay open trouble)
6
Drainage problem.
- Is the drainage hose bent?
- Is the winding of the drainage pump continuous?
- Is the drain filter clogged by waste?
• If above points are not found, the PCB assembly is out of order.
Replace it.
7
Dehydration problem.
- Unbalance is detected.
- Put in the laundry uniformly and start again.
8
Abnormal noise during SPIN.
- Is the pulley nut loose?
- Is the transport safety device removed?
- Is the product installed on a level and stable surface?
(Little noise may be generated during the high-speed SPIN.)
9
Leak breaker or current/leak
breaker is down during washing.
<When the leak breaker and current breaker is installed separately>
- When the leak breaker is down, check and make sure it is grounded.
- 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 current when the
washing machine and other apparatus are used.
In this case, execute a cold water wash to check whether the current capacity
is lacking.
