When performing troubleshooting and part replacement during servicing, note the
following safety
precautions:
1.1 Safety Precautions
1.1.1 Use Genuine Parts
The components of the washing machine have safety features such as non-combustibility
and voltage with standing. Therefore, always use the same part as suggested by the maker.
In particular be sure
to use only designated parts in case of major safety parts identified by the marker.
1.1.2 Grounding
Connect the grounding wire to the shell plate ,and bury it under at least 25cm of earth:
alternatively, connect the ground wire to the appropriate pin on a properly grounded
power receptacle. Never connect the wire to a telephone line, lightning rod, or gas pipe.
1.2 Servicing Precautions
1.2.1Observe Warnings
Be sure to follow special warning and precautions that are described on part labels and in
the owner'
manual.
1.2.2 Parts Assembly and Wiring
Be sure to use insulation material(such as tube and tape).And be sure to restore all parts
and wires to their original position. Take special care to avoid contact with sharp edges.
1.2.3 Perform Safety Checks after Servicing
After servicing, check to see that the screws, parts, and wiring are restored to their
original positions, and check the insulation between the external metals and the socket
plug. In addition, place the washing machine in a level position (less than1 degree)to
prevent vibration and noise during operations.
1.2.4 Insulation Checks
Pull out the plug from the power receptacle, pour water into the spin tub, and then set
the timer.
Check to see that the resistance insulation between the terminals of the plug and the
externally
exposed metal is greater than 1M .
Note :When it is impossible to insulation check with a 500V insulation resistance
tester, use other testers for inspection.
1.3 CAUTIONS FOR SAFETY
• Please observe the following notes for safety.
• The symbols indicate as follows.

WARNING
CHECK INSULATION
RESISTANCE
After repair, measure insulation resistance between the
charging part(power cord plug) and the non-charging
metallic part (ground) with an insulation resistance meter
(500V).The resistance shall be 10M or more.
Failing to check the insulation resistance may cause a short
circuit, electric shock or other diseases to the customer.
DO NOT MODIF
Do not modify the product.
An electric shock or ignition may occur.
DO NOT MODIFY
Only a repair technician can disassemble and repair.
An electric shock, ignition or malfunction may cause injury.
USE EXCLUSIVE
SOCKET
Use an exclusive 110 VAC/15 A socket for the washing
machine.
Use an exclusive 220VAC/17A socket for the washing
machine.
Otherwise , an electric shock or ignition may cause. Sharing
the same socket with other instrument causes heating of a
branch socket and result in a fire.
CONNECT
GROUNDING WIRE
Connect the grounding wire.
Failing to do so may cause an electric shock when a short
circuit occurs.
Consult an electric work shop or a sales shop.
DO NOT USE WET
PLACE
Do not install in a bath room or a place exposed to wind or
rain.
An electric shock or a short circuit may cause a fire.
DO NOT SPLASH
WATER
Do not pour or immerse electrical parts into water or liquid
solution.
An electric shock or ignition may occur.
REMOVE DUST
Wipe off dust adhered to the plug of power cord.
Dust may cause a fire.
AVOID
INFLAMMABLE
Do not put inflammable into the washing tub.
Do not put cloths stained with kerosene, gasoline, benzene,
thinner, alcohol, etc. lt may cause a fire or explosion.

WARNING
DO NOT TOUCH
Do not touch the laundry before the spin basket stops
completely.
The laundry entangles your hand causing an injury even if
the basket rotates slowly. Pay special attention to children.
INSTALL
CAREFULLY
Ask an electric work shop to install the product.
Install the product securely and safely according to the
electrical equipment technical standard and the wiring
standard.
Incorrect work causes an electric shock and a fire.

2.2 Self-check
Push the buttons of function and pre-washing without loosening, in the meantime
screw the program knob to the position of cotton and keep 3s, then the program will
be in the state of self test. When the buzzer toots, all the indicating lights glitter 3
times ( pushing 0.5s, the 0.5s light is on and off), then the lights are on all the time.
When the knob screw to the following position in this time and push the button of
start/off, the test is effective.
1. Delay washing test (cotton normal water):the maximum inlet water time is 10s.
2. Main washing test(cotton 40℃): the maximum inlet water time is 10s.
3. Washing test(cotton 60℃): the maximum inlet water time is 10s.
4.Heating test(cotton 90℃): estimate whether the water level is 1, if not, adding
water to 1, then begin to heat in the maximum of 10 minutes.
5.Tub leaking test(speedy washing 30℃): estimate whether the water level is 1, if not,
adding water to 1, according to cycle of clockwise 10s-stop 2s-anticlockwise 10s to
test in the rotate speed of 250rpm (fault alarm E6/E7).
6. Drain test (single drain): if the water level is below 1, it is plus 40s (malfunction
alarm E3).
7. Dehydration (single dehydration): judge whether the water level is below 1, if not,
drain water until it is below the 1 plus 20s, then dehydrate in the maximum of
speed (unbalanced test is needless), the maximum time is 10 minutes(fault alarm E5).
NOTE:
1) The tests foregoing are reversible.
2) It is need to close the door lock before each test , or else the door clock is
malfunction alarm E1.
3) The knob can be screwed to every position, the corresponding test is valid once
pushing the start/pause button.
4) If the knob is not in the position of that test, there is not responsive.
Exit need to close the power.
2.3 Marketing-show (no-water testing)
Target: in order to display the washer’s operation in the supermarket, set up
display mode.
Operation program: push the function + pre-washing button and screw the knob
to 40℃, keeping 3 minutes, when the buzzer toot, it enter the sales display mode. In
the mode, the washer without and the heater without power, run the two minutes
standard cotton washing + washing program and three minutes dehydration program
after pushing the start/pause button, then stop, if you push the start/pause button
