Error message. Motor ov e rhea t protection or is damaged.
Troubleshooting:
Cut off power and check if motor wires
are connected well
Y
Measure if the resistance of motor
binding by multimeter, is it as followed?
[1.78±8% (at 20 C)]
5 -10
8 -9[1.90±8% (at 20 C)]
Y
Pull out the wire connection of motor
and driving computer board. Then
check if circuit is open by multimeter
Error message. Water lev e l ex c eed
Troubleshooting:
Check if water switch hose and air collector
are jammed
N
Pull out water switch inserts and turn on
power, then set wash mode. while water
is entering at the position of 3/4 glass
window, check the resistance between 11
and 16, is it 0 ? Check the resistance
between 11and 14 ,is it infinite?
N
Without power ,connect inlet pipe to inlet
valve, then open the tap and observe if
water is entering in dispenser
N
Without starting but electrifying, measure
the import voltage of inlet valve, is it
between AC 220-240V?

about ten minutes, and then test
again. If the resistance is natural, it
is caused by overheated protection.
Then check and deal
overload, abnormal voltage. If not,
please replace motor
