Power Error
2E
ERROR!
High/Low Voltage Detected
- 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)
PF -
- This error is not a fault but occurs during a
momentary power failure
: 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.
Communication
Error
AE
Electronic Control Problem
ERROR!
- The signals between the sub and main PBAs are not
sensed because of commuication 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.

A Button is either stuck or is
being pressed continuouly.
ERROR!
- The Power button is pressed continually (for more
than 12 seconds).
- A switch is jammed or stuck due to be pressed
unevenly due to deformation of the control panel or
button.
- 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.
Sr
Power Interruption

the door open
operation
dL
(During
operation)
ERROR!
The Door was unlocked wh-
ile the washer was running.
- This occurs in the Boil wash because the door is
pushed due to a pressure difference from internal
temperature changes
When the door is
not locked after
the door close
operation
LO
(Unlock
Fail)
The Door will not unlock.
ERROR!
- The door lock switch terminal is connected incorrectly.
- The door lock switch terminal is broken.
