Chapter2 Product Features
New "smiling face" appearance: The appearance of this washing machine
is novel.It looks like a smiling face , bringing you good feeling.
Transparent view window, new appearance:It adopts transparent view
window on the top lid. Therefore the user can see the washing directly without
having to open the top lid. It is more convenient to use.
Heavy: It has special "HEAVY" function applicable for very dirty laundries.
Washboard type stainless steel inner tub: The stainless steel inner tub of
this washing machine is washboard type.It can kneed laundries adequately
and wash cleaner,reducing abrasion at the same time.
Smaller volume,larger capacity: It adopts limited design to make good use
of room,smaller volume and larger capacity.
Music buzzer: Adopt the nationally initial music buzzer. The former boring
buzzer is replaced by the nice music, bringing you more interesting life.
Automatic power-off function: If the washing machine is not started after
the power is switched on, or the washing is finished, the power will be
switched off automatically for the sake of safety.
Alarm against breakdown: the washing machine will alarm with abnormal
display and buzzer when the drain hose is not put down, or when top lid is
open, or the automatic program can not be performed.
Imbalance-revising function: during spinning, if the laundries are slanting
and bumping the tub, the washing machine will add one rinse automatically to
revise the imbalance.

It adopts pouring seal with polyurethane on the surface. The light-emitting diode
is sealed with insulation bushing to avoid humidity. To avoid splashing, the surface
of computer plate and box and the operation components of the control panel seat
are coated with control panel film.
2)Structure of the top lid
The top lid adopts transparent view window structure. If the top lid is closed, you
can observe the running of the washing machine through the transparent lid.
Please pay attention in installation of the hangers that the spring of the hanger
at the motor side (two) is different from those installed on the other hangers (two).

3)Power transmission system
During washing, the rotation of Motor 1 is transferred to Follower 5 from Drive Wheel 2 through
Belt 3. Meanwhile, Ratchet 7 will be braked by Pawl 8 through the action force of the spring, and
the movement will be transferred to Center Gear 9, and then be retarded and transferred to
Tie-rod 10 through a planetary gear mechanism consisting of Center Gear 9, Planet Gear 10 and
Spin Shaft 4 (inner gear), then Tie-rod 10 is connected to Pulsator 12 via a spline shaft.Therefore,
Pulsator 12 will move along with the clockwise and counterclockwise rotation of the Motor 1.
During spinning, the rotation of Motor 1 is transferred to Follower 5 from Drive Wheel 2 through
Belt 3. Meanwhile, Pawl 8 will leave Ratchet 7 by the action of the puller. Clutch Reed 6is twisted
tightly on the down part of Spin Shaft 4. The Spin tub 13 is connected to Spin shaft 4 with flange.
The movement of Motor 1 will be retarded by V-belt, and then transferred to Spin shaft 4 and
make the Spin tub 13 to spin.

The most obvious feature of this machine is that during washing, the
pulsator and inner tub rotate to opposite direction, and thus make double
washing effect. It is realized as following three points:
The retarder of this washing machine is different from former ones. It
adopts dual ratchet and dual pawl structure. The brake arm has two
action steps: the first step is applicable for washing mode: the brake belt
is opened to make the brake wheel free. But the pawl does not leave the
ratchet. The clutch spring keeps loose; the second step is applicable for
spinning. The pawl leaves the ratchet. The clutch spring integrates the
input shaft and clutch shaft and performs the spinning with the drive of
motor.
There are two strokes of the drain motor: the first stroke is used in
washing. The second stroke is used in spinning.
Comparing with the former drain valve, this machine adopts dual
valve pipe as the substitution of the former single valve pipe, which can
guarantee that during washing the pulsator and the inner tub rotate to
opposite directions, and thus make hand-wash type washing. In spinning,

4-8 Key points in disassembly
4-8-1 Points of attention in maintenance
1)General attention
2)Points of attention in usage of electric components
The part of control panel seat
Be sure to pull off the power plug in disassembly or maintenance
Use stipulated crimp terminals in connecting the wires between the
conducting wires as far as possible, and fix with suitable tools, and
insulate with insulation tape completely.
In inserting the conducting wires, be sure to plug the pins to the root
and make it hard to be pulled out.
If welding is needed, be careful not to touch the plastic or other
insulation parts with the iron.
When connecting the wires, be sure not to make the wire touch the
mobile parts like the belt, radiating pulley and jib etc., and the sharp
protruding parts and the parts with high temperature (motor). Connect
and fix the wires as per their original mode.
If there's metal object at the wire fixing point, be sure to insulate with
insulation materials.
Retain the dismantled screws for future usage in installation.
In case that the power is on, the earthing circuit of the computer
sequencer can have 120V voltage to earth. Take care not to get
electric shock.
Store the computer sequencer and driver under 4 -30 . Avoid direct
sunlight.
In trouble-shooting, it may require hot-line work. Please be extremely
1)Method of opening the control panel
A.Open the back cover. Loosen the three locking belt fixed on the
cabinet (used
in inner wiring), to loosen the inner wiring.
B.Loosen the four screws used to install the control panel seat (rear and
side).
Lift the rear upwards. Loosen the control panel seat from the inlay of
Do not lift the control panel seat by force, otherwise the safety switch
control rod may get transformed, and the jointer part of the connecting
pipe of the water level sensor may be loosened, therefore influence
the normal operation of the microswitch and water level sensor.
After opening the control panel seat, hold it with one hand or lean it on
supporter like the wall. Do not put it down.

1) Method of disassembling
A.Loosen the two motor bolt unit to dismantle the motor. To adjust the
tension of the belt, loosen the bolts and move the motor left and right.
B.Loosen the four fastening screws to dismantle the delivery shield.
C.Loosen the three fastening bolts to dismantle the drain motor.
D.In dismantling the drain valve, first loosen the screws, then rotate
combination part with the drain hose, overflow hose and outer tub
slowly to make it loose. Then dismantle the drain valve.
E.In dismantling the inner tub, first take off the outer tub cover, then
dismantle the pulsator, finally dismantle the inner tub. Handle with care
when taking the inner tub off from the outer tub.
2) Points of attention in assembly
In installation of the drain valve, please smear a piece of 801 glue at
the connection part between the drain valve and outer tub and between
the overflow hose and drain hose to guarantee that the drain valve will
not leak.
In fastening the screws, make it tight without sliding.
Take care not to scratch the cabinet and influence the appearance of
the Machine.
4-8-2 Points of attention in assembly
Fix the wiring in the control panel seat to its original position. Do not
make it touch sharp corner and mobile position. The space surrounding
the computer sequencer is rather narrow. Please dispose it carefully
and do not make the transformer press the wires.
Confirm that the control panel seat is installed to proper position of
the cabinet. Pay attention on the adjusting of the gap between the
control panel seat and the cabinet.
