Display Meaning
No trouble Trouble
Cause Solution method
OE
Over fl ow error.
(If water level frequency is sensed over fl ow 15.01khz
-21.00khzin 5sec, this error will occur)
1. Is the water supply valve bad?
2. Is the water level sensor bad?
3.Is the water frequency detect circuit worked well?
1.Is the winding of the water supply continuous(4.2k ω )?
2.Check if there is frequency out put from water level sensor.
3.Is the hose connect well?
6.Is the PCB connector connect well?
LE
Natural drain/water leak error.
(If more than 4 times of water supply and safe water level of heater are
sensed for each course, this error will occur) 1.Exam if the tub is leaked?
2.Exam if the water level frequency circuit is worked well?
3.Is the water level sensor worked well?
1.Exchange tub.
2.Check sensor circuit.
3.Exchange water level sensor.
HE2(H2)
If there is no higher change in temperature than 2
℃
for 1-11 minutes after
during the initial time of heating, this error will occur.
1.Is the heater connected well?
2.Is the heater bad?
3.Is the temperature sensor circuit worked well?
1.Is heater pin connected well?
2.Check the resistance of
Heater (23
Ω ~29 Ω ).
3.Check the sensor circuit.
tE
Water temperature sensor error.
(If thermistor is lower than 0.2V or higher than 4.5V, this error will occur) 1.Is the the temperature sensor circuit worked well?
2. Is the heater bad?
1.Check the temperature sensor circuit.
2.Exchange the heater.
3E
Motor tacho error.
(If tacho signals are inputted less than 2 for 2sec after motor started, this
error will occur) 1.If the feedback circuit of the motor tacho is worked well.
2.Is the motor bad?
1.Detect the motor tacho input system.
2.Exchange the motor.
bE
Motor TRIAC short error
(If tacho signals are inputted more than 300 every 1sec in the operational
interval less
than 90rpm, this error will
Occur) Motor traic short error. 1.Exchange PBA.
2.Exchange motor.
3.Exchange Assy-wire harness.
7E/t1
Heat sink temperature sensor error.
(If thermistor is lower than 0.2V or higher than 4.5V, this error will occur. It
will not displayed in normal course, but displayed in engineering exam and
PCB test mode) 1.The temperature probe of heat sink is bad.
2.The temperature sensor circuit is abnormal?
1.Exchange the temperature probe.
2.Check the temperature sensor circuit.
13E
Correspond error.
(If there is no signal displayed after main micom correspond is sensed for
longer than 10sec for drying model) Check whether the correspond wire is connected well. Reconnect the correspond wire.
8E
Overloading error.
(For drying washing machine, it’s sensed circuit abnormal by sensing fault
signal; IPM overloading current caused
Abnormal being sensed.) Micom into is sensed fault signal for 5sec continuously. Check fault sensor circuit.
tE1
Drying temperature sensor error.
(If thermistor is lower than 0.2v
，
this error will occur)
1.The temperature probe of drying heater is abnormal.
2.Check whether the temperature sensor circuit of drying heater is
abnormal.
1.Exchange the temperature sensor probe.
2.Check the circuit.
FE
Frequency conversion fan hall sensor abnormal.
(There is no hall sensor signal input after fan motor worked for 300msec.
this error will occur) 1.Frequency conversion fan is abnormal.
2.Fan’s drive control circuit is abnormal.
1.Exchange fan.
2.Check fan’s drive control circuit.
EE
For drying washing machine, overheating error.
(This error will occur when input temperature is reached 160
℃ for 5sec)
1.The temperature probe of drying heater is abnormal.
2.Check whether the temperature sensor circuit of drying heater is
abnormal.
1.Exchange the temperature sensor probe.
2.Check the circuit.
