Description
The water level fails to drop below the Reset Water Level
within 15 minutes.
Door fails to unlock after 3 attempts.
When the filling continues for more than 16 minutes or there
is no change of water level for 3 minutes
Door fails to lock after 3 attempts.
Water Level Sensor Trouble.
(When the input signal from the water level sensor is out of
range, the unit will send out beeping sounds and halts the
cycle.)
A fault is detected in the water level sensor.
Data (frequency) shows the water level is at or above the
overflow water level. (When this condition is detected, the
machine will automatically starts draining water until the water
level falls below the overflow water level)
Unbalance or cabinet bump is detected during final spin,
which prevents the drum from spinning over 400 rpm. (Never
exceeds 400 RPM due to unbalanced load)
EEPROM Fault. (Program settings are being reset.)
Jammed Key.(When key input signals are coming out for
more than 30 seconds, it is regarded as a jam.)
Door is detected as open when the motor is operating.
Door is detected as open while it is trying to lock the door.
Motor hall sensor signals come out without motor operation.
Abnormal high/low temperature or resistance (Thermal
sensor or PBA) resistance.
MICOM is attempting to drive the motor but is not getting any
response signals from the hall sensor. Visual check shows
motor is not running. (Locked, Defective Hall Sensor or
Overload)
System Relay (Main Relay) Failure. (PCB does not notice the
relay operation when there should be.)
Heater Relay Failure (No Heater Relay Check Signal)
Over-current is detected. Motor won't turn.
(IPM detects over-current.)
Voltage for motor control bus is over specified limit.
Voltage for motor control bus is under specified limit.
MEMS Sensor Failure. (No MEMS Sensor Check Signal)
Silver Care Kit (Silver Care PCB) Failure.
It occurs when there is power failure during the washing.("PF"
is not an error. It is to inform the user of power failure.)
Suds is detected during the washing session. ("SUdS" is not
an error. If the washer is in suds period, "SUdS" will light up
instead of remaining time.)
Corrective Action
Go to " Will Not Drain" Troubleshooting
Section.
Go to " Will Not Unlock" Troubleshooting
Section.
Go to " No Water Fill" Troubleshooting
Section.
Go to " Will Not Lock" Troubleshooting
Section.
Go to "No Water Fill" Troubleshooting Section.
First check to see that all of water valves are
not stuck. If water valves are OK, check water
level sensor.
Go to "Wet Clothes" Troubleshooting Section.
Go to "EEPROM Clear Mode" If display
shows "FAiL",Replace Machine Control
Board.
Check all of keys. If A key is sensed to be
pressed, all keys will do not respond.
Check for loose wire connections.
Go to "Quick Test Mode" and then do Door
lock/Unlock Test and Motor Test.
Go to "Quick Test Mode" and then do Door
Lock/Unlock Test
Replace Machine Control Board.
Go to " Board Input Test" and check Water
Temperature. Check loose or pinched wires.
Replace PCB or thermistor.
Evaluate wire harness for loose or unhooked
connections. Go to " Quick Test Mode" and
test Motor.
Replace PCB.

Evaluate wire harness for loose or unhooked
connections.
Go to " Quick Test Mode" to test Motor.
