Check if drain pump acts by touching
pump position
Y
Check if drain pump or
drain pipe is jammed,
And open the filter and
clean
N
Cut off the power and choose spin
program to start ,then check the import
voltage of drain pump, is it between
AC 220-2240 V?
Replace drain pump
N
Cut off power and pull out water level
pressure switch wire connection. Set
spin program to start. Check the export
voltage to drain pump, is it between AC
220-240V?
Replace PCB
NTC exist open circuit. Replace it

Y
Check if NTC is connected properly
Cut off power and measure the resistance
of temperature sensor by
multimeter, is
it between 5-14kΩ ?

N
Replace PCB
Check if water is emptied
Y
Cut off power and water level pressure switch wire
connection, measure the resistance of 11 and14 pin,
is it infinite? If not, it is water level pressure switch
failure and replaces it. If it is, then repair and check
PCB and wire as followed.
N
Y
The wire between PCB
and drain pump is not
connected properly.
Replace the wire.
Check the white wire and black wire of NTC,
are they connected well?
Connect all wires well
Disconnect the white wire and black wire
from PCB, and measure if the resistance
between white wire and black wire of PCB, is
it infinite?

Turn on power, and set pre-wash
mode, then start. Check the import
voltage of electromagnetic valve by
multimeter is it between AC
220-240V?
Electromagnetic valve must be broken, please
replace it.
The wire connected PCB and inlet valve is not
properly. Please reconnect it or replace it.
Y
Cut off power and check if motor wires
are connected well
Reconnect well
Y
Measure if the resistance of motor
binding by multimeter, is it as followed?

Check if export voltage from PCB to
electromagnetic valve, is it between
AC 220-240V?
N
Put the motor in normal temperature
about ten minutes, and then test
again. If the resistance is natural, it
is caused by overheated protection.
Then check and deal with
overload, abnormal voltage. If not,
please replace motor
Repair wires
Pull out the wire connection of motor
and driving computer board. Then
check if circuit is open by multimeter
