Water Level Sensor Problem
ERROR!
- The part of the hose where the water level sensor is
located is damaged (punctured).
- The hose is clogged with foreign material.
- The hose is folded.
- Too much lubricant has been applied to the insertion
part of the air hose.
- Hose engagement error (disengaged)
- Part fault (Faulty internal soldering)
- The water level sensor terminal is disengaged.
- Main PBA fault.
Motor Driving
Error and Hall
Sensor Error
3E
The Motor is not working
properly.
ERROR!
- The PBA connector terminal is not connected.
- The motor spin net is not engaged.
- The motor’s internal coil is damaged (short-circuited
or cut)
- The hall sensor terminal is not connected.
- Foreign material (a screw) has entered the motor.
This error
occurs because
of restrained
revolutions
E3
- Motor overloaded due to too much laundry (Non-
sensing)
- The motor hall sensor terminal is not connected.
- PBA fault
- The motor driving error from the PBA is weak.
: Unstable relay operation, etc.
This error
occurs when an
interference is
generated due
to too much
laundry, etc.
bE
- This occurs due to erroneous operating signals from
the motor hall sensor.
- The IPM terminal of the main PBA is not connected.
- The DD motor cover is out of place.
- The PCB housing terminal is not connected.
- PBA fault
- DD motor fault
Water Supply
Error
nF
Low Water Pressure
ERROR!
- Foreign material is entering the water supply valve.
- The water supply valve terminal is not connected.
(Wire disconnected)
- The warm water and rinse connectors are wrongly
connected to each other.
- This occurs if the PCB terminal from the drain hose
to the detergent drawer is not connected. Check
whether the transparent hose is folded or torn.
If this error
occurs in the
Wool course
- The cold and warm water supply hoses are wrongly
engaged into each other.
- The temperature of the water supplied through the dry
valve during a dry cycle is sensed as higher than 70
˚C.
The water
supplied for 1
minute drying
the drying cycle
is 0.3 ~ 0.4 L.
- The water temperature is sensed as higher than 50 ˚C
in the Wool or Lingerie courses.
Drain Error
nd
No Draining
ERROR!
- The pump motor impeller is damaged internally.
- The wrong voltage (220 V → 110 V) is supplied to the
parts.
- Part fault
- This occurs due to freezing in the winter season
- The drain hose is clogged. (Injection error, foreign
material)
- Clogged with foreign material
- The water pump terminal is not connected: rubber
band, bills, cotton, hair pins, coins have collected
inside the drain pump ASSY.
