Washing Motor
3C5
3C6
3C7
3C8
• Overcurrent occurs during
motor operation
• Current sensing error
during motor operation
• Command rpm compared
to the current rpm
differences over 100rpm
• IPM temperature values
abnormally high
• Check the motor Power connector
terminal connections and contacts.
• Check whether there is the motor
power cable and power connector
or not. (“A”)
• 3C1 is displayed because
overloading occurs due to too
much laundry.
• If the hall sensor terminal is faulty,
replace the hall sensor.
• Check whether the stator of the
motor cover is damaged.
• Check for coil disconnections due
to foreign material.
• If the PBA control circuit is faulty,
replace the PBA.

Water Supply
4C
4C2
• Water supply value fault
• Main PCB fault
• Freezing in the winter
season
Check the water supply
valve whether only cold
model or hot and cold
model Incorrect connection
can occur an error
• If the water supply valve has a wire
disconnected, replace it.
• Check whether the water supply
valve is clogged with foreign
material and whether water is
supplied continually.
• Check whether no water is
supplied because of freezing in the
winter season.
• If the PBA relay operates
abnormally, replace the PBA.
1. Check the resistance for the water supply valve.
Resistance: 3.6 to 4.4 kΩ between two terminals
of each solenoid.
2. Check whether there is foreign material at the
inlet filter of water supply valve.
Drain
5C
• Drain pump fault
• Freezing in the winter
season
• Foreign materials in the
drain pump
• Main PCB fault
• Check whether the revolutions
of the drain pump motor are
restrained by foreign material.
• Check the same thing for the
natural drain process.
• Check whether the connections
are correct and if there is any wires
disconnected.
• If the drain pump operates
abnormally intermittently when the
temperature of the water in the tub
is high.
• If the motor revolutions are
restrained due to freezing in the
winter season, check the method
to remove the freezing and
remove as directed.
► DRAIN PUMP
Resistance: Approximately 225.8 to 229.8 Ω
between the Terminals for the Pump Motor.
