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.

Cut off power and check if motor wires
are connected well
Reconnect well

Measure if the resistance of motor
binding by multimeter, is it as followed?
5 -10
[1.68±8%

Replace PCB
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
