4E
The water is not supplied and water level does not reach the preset
level.
(If there is no higher change in water frequency than 100hz for 2
minutes during the initial time of water supply and if water level does
not reach the preset level in 10 minutes)
1.Is the tap open?
2.Is the water supply valve clogged
by something?
1.Open the tap.
2.Clean out of the waste that clog the
water supply valve.
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?
4.Is the PCB connector connect well?
5E
The water is not drained and other drainage problem.
(If water level frequency is still lower than the reset level frequency in
10 minutes after starting of water drain)
1.Is the drain hose hang?
2. Is the drain hose bent?
3.Is the drain
fi
lter clogged by the
waster?
1.Reset the drain hose.
2.Make sure the drain hose is unhindered.
3.Clean out of the waste that clog the drain
hose.
1.Is the drainage pump bad?
2. Is the water level sensor bad?
3.Is the water frequency detect circuit worked
well?
1.Detect the resistance of drainage pump(160
Ω
~190
Ω
)?
2.Check if there is frequency out put from water level
sensor.
3.Is the hose connect well?
4.Is the PCB connector connect well?
De(door)
Door open error.
(The door is unlocked after locking door in 5sec,this error will occur)
Door open.
Close the door.
Door lock is damaged.
Is the winding of the door lock continuous? If not,
change it.
UE
Unbalance.
The laundry is put asymmetry.
Open the door, put in the laundry uniformly
and start again.
HE1(H1)
1.If temperature increase to above 40
℃
for 1-2 minutes after during
the
Initial time of heating, this error will occur.
2.If temperature is higher than 95
℃
for each cause, this error will
occur.
Drainage immediately after heating
to higher temperature, then cooling
it.
Free convection cooling.
1.The heater temperature probe is bad.
2.Is the temperature sensor circuit normal?
1.Detect if the temperature probe is short circuit.
2.Check the sensor circuit.
1E
Water level sensor error.
It is a short circuit because of the
waterlogged sensor.
Dry the water level sensor.
1.Is the air hose of water level sensor connected
well?
2.Is the water level sensor connected well?
1.Reconnect air hose.
2.Exchange the water level sensor.
CE
If water temperature is sensed higher than 50
℃
for longer than
1sec,this error will occur.
It is supplied water higher than 50
℃
in special course.
Supply cold water.
Is the temperature sensor circuit worked well?
Check the temperature sensor circuit.
