- 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.
9E1,9E2 : Check the voltages.
(A check 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)
- The signals between the sub and main PBAs are not sensed
because of commuication check.
- Check the connector connections between the sub and main
AE PBAs carefully.
→ Check for incorrect or loose connections, etc.
- Remove the sub PBA C/Panel and check for any faulty
soldering.
AE2 - The diagnosis of the I/O Board communication check.
- The signals between The DR Module and main PBAs are not
sensed because of commuication check.
- Check The connector connections between The DR Module
AE3
and main PBAs carefully.
→ Check for incorrect or loose connections, etc.
- Remove The DR Module and Check for any faulty soldering.
- The signals between The WIFI Module and main PBAs are not
sensed because of commuication check.
- Check The connector connections between The WIFI Module
AE4
and main PBAs carefully.
→ Check for incorrect or loose connections, etc.
- Remove the WIFI Module and Check for any faulty soldering.
- The signals between The LCD Module and main PBAs are not
sensed because of commuication check.
- Check The connector connections between The LCD Module
AE5
and main PBAs carefully.
→ Check for incorrect or loose connections, etc.
- Remove The LCD Module and Check for any faulty soldering.
- The signals between the Inverter PBA and main PBA are not
sensed because of communication check.
- Check The connector connections between the Inverter PBA
and main PBA carefully.
AE6
→ Check for incorrect or loose connections, etc.
- Remove the Inverter PBA and Check for any faulty soldering.
- 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 check may occur when the screws that hold the sub PBA
BE2
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.
