Causes
- The pump motor impeller is damaged internally.
- The wrong voltage (220 V → 110 V) is supplied to
the parts.
- Part fault
- This occurs due to freezing in the winter season
- The drain hose is clogged. (Injection error, foreign
material)
- Clogged with foreign material
- The water pump terminal is not connected: rubber
band, bills, cotton, hair pins, coins
- Check the consumer's power conditions.
: Make sure to check the operating voltage.
Connect a tester to the internal power
terminals during the Boil or Dry operations
and observe the washing machine's operation
carefully.
: Check the voltages. (An error occurs when
under or over voltage is supplied.)
: Check whether a plug receptacle is used.
When the connecting wire is 1m, a momentary
low voltage may drop up to 10 V
- Main PBA fault (sometimes)
- Please check the door conditions if there is no
problem in a consumer's power and main PBA.
(Only this model)
- This error is not a fault but occurs during a
momentary power failure
: If started again when this error code is
displayed, the operation restarts from the cycle
that was stopped due to the power failure.
: If the washing machine is not operating and
this error code is displayed, it is displayed to
notify that a power failure has occurred.
- The signals between the sub and main PBAs are
not sensed because of a communications error.
- Check the connector connections between
the sub and main PBAs carefully. → Check for
incorrect or loose connections, etc.
- Remove the sub PBA C/Panel and check for any
faulty soldering.
- The Power button is pressed continually (for more
than 12 seconds).
- The switch is pressed unevenly because of a
deformation of the control panel.
- This error may occur when the screws that hold
the sub PBA in place are tightened too much.
- A button other than the Power button is
continually pressed (for more than 30 seconds).
- Deformation of an internal plastic injection part
- A screw for assembling the sub PBA is tightened
too much.
- The main relay of the PBA is short-circuited.
- The main relay terminal is connected incorrectly.
(The terminal is bent and contact cannot be
made.)
