Usethismaterialasareferencewhendisassemblingandreassemblingtheproduct.
Part Figure Description
Disassembling and
Repairing the Rear
Motor
1. Removethe2screwsholdingtheBack-Cover
at the back of the washing machine and
separate the Back-Cover pushing it downwards
(Assemble it by lifting it upwards,)
2. AfterseparatingtheBack-Cover,removethe
M19nutholdingtheMotor.
 Toremoveit,turnitcounter-clockwise.Asthe
Motor also rotates if the nut is turned slowly,
torqueitquicklyandrmlyinasingleaction.
Do not remove the nut by inserting a screwdriver
into the Motor, as this may result in a problem
withthemotor.
3. RemovetheM19nutandwasherandthen
separatetheRotor.
Since removing the rotor requires a lot of
strength due to the magnetic force of the Rotor
and it may come off suddenly, your hand or
arm may be injured by the edge of the Stator
orFrame.Thereforetakeprecautionwhen
separatingit.
You can separate the connector by pressing the
naveloftheHousingandpullingitoutside.
HALL SENSOR
MOTOR WIRE 4. SeparatetheMotorWireandHallSensorwhile
pressingthenaveloftheHousing.
Take precaution when you do this because the
HallSensorpartiseasilyshocked.
5. Separatethe6M10screws.→Separatethe
AssyBracketMotor→SeparatetheStator.
 Whenremovingthelastofthe6screws,hold
the Stator as it may fall when the screws are
removed.
4Check Points for Troubleshooting
1. CheckifthereisanyaliensubstancebetweentheRotorandtheStator.
2. Checkifthemotorpower(Blue,White,Red)wireisconnected.
3. CheckiftheHallSensorwireisconnected.
 TheorderofthemotorwiresisBlue,White,andRedfromtheright.Checkifthe
resistancebetweenBlue-White,White-Red,andRed-Blueisequalto15Ω.

 MakesuretoseparatetheThermostatrstand
thenseparatetheHeater.Ifyoufailtoobserve
this order, it may result in a shock and be
damaged.
3. ReleasethenutholdingtheHeaterwithanM10
toolandthenseparatetheHeater.
 Donotcompletelyreleasethenut.
PulltheHeaterforwardafterreleasingthenut.If
theHeaterisdamaged,itmaycauseaproblem.
Therefore unfasten the nut using spanner
or wrench manually without using pincers or
tweezers.
When you re-assembly the heater, make sure to
install the heater exactly onto the Bracket inside
theTub.Ifitisnotproperlyinstalled,itmay
causeare.Inaddition,completelyinsertthe
packing part into the Tub when assembling it so
that the packing part is completely attached onto
theTub.
4Check Points for Troubleshooting
1. CheckiftheresistanceoftheHeaterisequalto27.1Ω(forthe1900Wproduct),or26.2Ω
(forthe2000Wproduct).
2. CheckiftheresistanceoftheThermistorisequalto12kΩ(atroomtemperature).
