Code Description Corrective Action
The water level fails to drop below the Reset Water
Level within 15 minutes.
Check for Foreign material in pump or hoses. Verify
the wiring harness is connected properly. Check the
water pump terminal. Check for freezing
When the water fill continues for more than 16 minutes
or there is no change of water level for 3 minutes
Check the water valve wiring harness. Check the
water supply valve for clogging with foreign material
and whether water is supplied properly. Check for
reversed fill hoses. Check water temperature, if
sensed as higher than 50 ˚C in the Wool or Lingerie
cycle it will create error. Check the relays, if they
operate correctly replace the Main PCB.
5 nF1 5 The Hot/Cold water connection is not correct Correct Hot/Cold hose connections
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 halt the cycle.)
Check the Hose where the sensor is connected, may
be loose, pinched, damaged or clogged. Also check
the sensor it may be disconnected or defective. The
Main PCB may also be defective
A fault is detected in the water level sensor. Data
(frequency) shows the water level is at or above the
overflow water level. Drain process may also occur.
Water is supplied continually because the water
level detection does not work. - Verify the drain is
working properly. Verify the water valves shut off
fully. Finally check the water level sensor.
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)
Check type of laundry. Check whether it may cause
an unbalanced situation.- Educate the consumer to
press pause, reposition the load or remove a few
items. Check bulletin on WF218
9 - 11 EEPROM Fault. (Program settings are being reset.)
Go to “EEPROM Clear Mode” If display shows
“FAiL”, Replace Machine Control Board
Jammed/Stuck Key. (When key input signals are
detected for more than 30 seconds, it is a stuck key.)
Check all of keys. If A key is sensed to be pressed,
all keys will not respond
Door is detected as open when the motor is operating.
Door is detected as open while trying to lock the door.
Door fails to unlock after 3 attempts.
Door fails to lock after 3 attempts.
Check the door switch and latch alignment. Check
the latch for damage. Check the wiring harness to
the latch. Check the door switch. Replace if faulty.
Finally verify the operation of the Main PCB
Abnormal high/low temperature or resistance (Thermal
sensor or PBA) resistance.
Check loose or pinched wires. Check thermistor if
OK Replace PCB.
System Relay (Main Relay) Failure. (PCB does not
notice the relay operation when there should be.)
17 Hr 36 Heater Relay Failure (No Heater Relay Check Signal)
Check for short or a wire disconnected to the heater
circuit. Check for tub contacting the heater or if the
water in the tub is frozen or there is no water. The
error is triggered by temperatures above 145C. If the
heater is OK, replace PCB. An Hr error occurs if the
steam heater is faulty, replace it.
Motor Drive Error or Hall Sensor error
Check the motor drive & Hall sensor connector.
Check for foreign object inside the motor/stator or
motor/stator damage. The drum may be overloaded
with clothes or the relay or PCB may be defective.
21 8E 8E MEMS Sensor Failure. (No MEMS Sensor Check Signal) Check MEMS PCB ,Main PCB & Wire-harness
22 7E 7E Silver Care Kit (Silver Care PCB) Failure. Check Silver Care PCB ,Main PCB & Wire-harness
23 PF - It occurs when there is power failure during the washing.
(“PF” is not an error. It is to inform of power failure.) -
Suds is detected during the washing session. (“SUdS”
may light up instead of remaining time.)
“SUdS” is not an error. Guide a user to reduce
amount of detergent usage.
25 9E1 EMC Filter issue or a noise spike from an external device
Communication error between SUB PBA and MAIN
PBA
Check Main PCB & Sub PCB Wiring harness. If OK
replace PCB
System error Replace PCB Replace PCB Replace PCB
