The water level fails to drop below the Reset Water Level
1 nd 1
within 15 minutes.
2 LO 2 Door fails to unlock after 3 attempts.
When the water fill continues for more than 16 minutes or
3 nF 3
there is no change of water level for 3 minutes
4 FL 4 Door fails to lock after 3 attempts.
5 nF1 5 The Hot/Cold water connection is not correct
Water Level Sensor Trouble. (When the input signal from
6 LeE or LE 8 the water level sensor is out of range, the unit will send out
beeping sounds and halt the cycle.)
A fault is detected in the water level sensor. Data (frequency)
7 OE E shows the water level is at or above the overflow water level.
Drain process may also occur.
Unbalance or cabinet bump is detected during final spin,
8 dc 10
which prevents the drum from spinning over 400 rpm.
(Never exceeds 400 RPM due to unbalanced load)
9 - 11 EEPROM Fault. (Program settings are being reset.)
Jammed/Stuck Key. (When key input signals are detected
10 E2 15
for more than 30 seconds, it is a stuck key.)
11 dL 18 Door is detected as open when the motor is operating.
12 12 dS dS 22 22 Door is detected as open while trying to lock e door. Door is detected as open while trying to lock the door
13 bE 25 Motor hall sensor signals sent without motor operation.
Abnormal high/low temperature or resistance (Thermal
14 29
sensor or PBA) resistance.
MICOM is attempting to drive the motor but is not getting
any response signals from the hall sensor. Visual check
15 E3 2E
shows motor is not running. (Locked, Defective Hall Sensor
or Overload)
System Relay (Main Relay) Failure. (PCB does not notice
16 Sr 34
the relay operation when there should be.)
17 Hr 36 Heater Relay Failure (No Heater Relay Check Signal)
Over-current is detected. Motor won't turn. (IPM detects
18 3E 3E
over-current.)
19 2E 91 Voltage for motor control bus is over specified limit
20 2E 92 Voltage for motor control bus is under specified limit.
21 8E 8E MEMS Sensor Failure. (No MEMS Sensor Check Signal)
22 7E 7E Silver Care Kit (Silver Care PCB) Failure.
It occurs when there is power failure during the washing.
23 PF -
("PF" is not an error. It is to inform of power failure.)
SUdS Suds is detected during the washing session. ("SUdS" is not
24 -
or an error. If the washer is in suds period, "SUdS" will light up
Sd instead of remaining time.)
Description
th
Corrective Action
Go to " Will Not Drain" Troubleshooting Section.
Go to " Will Not Unlock" Troubleshooting
Go to " No Water Fill" Troubleshooting Section.
Go to " Will Not Lock" Troubleshooting.
Correct Hot/Cold hose connections
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 connections. Use "Quick Test Mode"
do Door lock/Unlock Test & Motor Test.
Go to "Quick Test Mode" and then do Door Q
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.
Replace PCB
Check wire harness for loose or open connections. Use
" Quick Test Mode" to test Motor.
Check AC line voltage - Replace PCB
Check AC line voltage - Replace PCB
Check MEMS PCB ,Main PCB & Wire-harness
Check Silver Care PCB ,Main PCB & Wire-harness
