Error message. Motor overheat protection or is damaged.
Troubleshooting:
Error message. Water level exceeds protection value.
Troubleshooting:
Replace PCB
N
Check the import voltage between M1 wind
and M2 wind, is it between AC 220-240V?
Cut off power and check if motor wires
are connected well
Reconnect well
N
Y
Measure if resistance of motor winding by
multimeter,is it as followed?
the resistance between M5and M10 is
1.67~1.85Ω. the resistance between M8and
M9 is 1.69~1.87Ω.
N
Put the motor in nomal 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
Pull out the wire connection of motor and
computer board.Then check if circuit is open
by multimeter
Y
Turn on power and set spin mode,then
start.Check the import voltage
between red wire and red wires, is it
between 220-240V?
N
N
Check if water switch hose and air collector
are jammed
Clean water switch hose and air
collector
