Many of the performance failures of the dishwasher are not the result of mechanical troubles. And the
unsatisfactory washing result can usually be corrected without any service.

This manual deals first with the problems in performance. To have satisfactory washing result, you have to use the
machine correctly. First thing first, the dishes shall be placed in a correct manner. If the machine works well and
the washing result is unsatisfactory, you should check the layout of the dishes as follows:

Load the dishes as instructed in the user's manual.
Preparation of the dishes such as dumping the remaining food, and removing from the dishes food lumps,
starches in particular, shall be done prior to loading.
The dishes shall face the water flow from the spray arm for free washing. Do not place the dishes in an
overlapped way.
Load heavy pans and large soup bowls downwards. If the upper racks are barred from water flows, do not
place articles on them any more.
Leave some space in the front of the wire basket so that the water flow may wash out the dishwater powder
from the powder trough in the inner door.
On the fork/knife rack, the tableware shall be placed with handle down evenly. Do not load there the
articles that may fall out from the bottom.

III. Check of Performance: Loading of Dishes

IV. Check of Performance: Dishwasher Powder and Brightness Liquid

The water (pressure, hardness and temperature) and the dishwasher powder are the major elements that affect the
washing effect of the machine. Choose the right dishwasher powder and dosage according to the local water
condition, you will have satisfactory washing result.

Use only the fresh and dry dishwasher powder of the designated brand. Outdated powder will reduce the
washing effect.
Contact the local water supply company for the water condition, if applicable. The higher the water hardness is,
the more powder shall be used.

Check the brightness liquid in the dispenser and add without delay if it is insufficient. The brightness liquid

helps the water to drip, making the dishes easy to dry and curbing the formation of water specks on the surface
of the dishes.

V. Power cord

The power cord of the dishwasher usually has a three-pin plug. Connect
the power supply as instructed in the user's manual.
If the dishwasher does not work, the power cord might be in the fault.
Most of the power cord troubles arise from damaged cord or loose
connection, and are visible.

Attention: to avoid electric shock, the power socket and power cord shall
be well grounded. Never use two-hole conversion connector that has no
ground terminals.

Steps for the check:

A. Disconnect the power prior to check.
b. Check the power plug. Improper connection may lead to bad contact.
c. Pull out the power plug in one stroke. Never pull at the power cord or use

a knife or other sharp tools that may cut the cord.

d. Check the power plug for overheat caused damage, corrosion or

looseness. In case of troubles, remove the outer casing (1) first, then the
rear panel (97) and replace the power cord (see Process 6).

e. Open the power cord clamp (96), remove the old power cord and replace

a new one with terminals. Secure the power terminals to the connection
terminals, and replace the power cord clamp.

f. Replace the rear panel and the outer casing.

VI. Removal of Outer Casing, Control Panel, Rear

This dishwasher is completely sealed. In order to repair internal parts, you have to remove the
outer casing before you can check and repair the parts.

Steps for the check:

a. Remove the three screws on the sides of the outer casing.

b. Open the door, and remove the six screws in the front of the inner container (see fig. 1 below). Note: do

not mix these stainless steel screws with the other ordinary ones.
c. Remove the seven screws in the back of the outer casing (see fig. 2 below).
d. Remove the screws in position D in fig. 2 below and take away the rear panel.
e. Lift up and away the outer casing from the dishwasher, and check and repair the internal parts.
f. Remove the six screws from the control panel bracing bar (58) (see fig. 3 below) and the two stainless

steel screws in position C of the inner container (see fig. 1 below), and pull out the control panel.
g. Remove the timer knob (see 1 in the appending diagram).
h. Turn the dishwasher upside down, remove all the screws in the bottom pan, open the cord clamp and

remove the bottom pan.

Turn all the switches to OFF and pull out the power cord plug.

An ohmmeter and the ability to read circuit diagrams are needed in this step.

Remove the outer casing.

Pull out the two input terminals of the timer motor and measure them with an ohmmeter (use the
range of R 100). If the pointer does not sweep partly across the line, replace the timer.

Refer to the circuit diagram to check the connection of the timer terminal to the elements.

VII. Check Internal Connecting Wire

The internal connecting wire connects the timer (60), the power switch (61), the inlet valve (95), the heating
elements (45) and other electric elements together. The wires shall be kept intact. Any damage to the wire
may cause overheat and result in broken wire. Common troubles to the internal connecting wire are broken
wire, bad connection terminal contact, and connection terminal insulation layer damages.

To repair the dishwasher, the ground shall be connected. When an electric component is replaced, check
whether the ground is connected again. This is a crucial step to avoid electric shock and short circuit.
Attention: to replace electric cord, use the cord of the same temperature resistance and specifications. The
specifications and temperature rise are marked on the cord.

Turn all the control knobs to OFF and pull out the power cord plug.
Open the outer casing, and, if necessary, remove the bottom pan.
Check the wires and connectors and replace the damaged ones.

Steps for the check:

VIII. Door Lock Assembly

Slider

micro switch

Micro switch spring

Linkage

The working mechanism of the door lock is that the linkage (8)
bolts up the door hook, which, in its turn, presses the micro switch
spring in the lock assembly to form a closed circuit. The lock
mechanism consists of the door lock holder (11), the slider (10)
and the micro switch (3). When the door is opened, the door hook
is withdrawn to release the micro switch, cutting the power supply
for open door protection.

In case of worn out slider, micro switch failure or deformed micro
switch spring, troubles may occur and the dishwasher will stop to
work as usual.

Steps for the check:

a. Pull out the power cord plug prior to servicing the door lock

mechanism.
b. Remove the outer casing.
c. If micro switch failure is the case, disconnect the micro switch,

remove the two screws and replace a new micro switch.
d. In case of deformed micro switch spring, adjust the spring

with nipper pliers so that the micro switch returns to its

original position when the slider is released and the micro

switch closes when the slider is pressed tight.

IX. Timer

The timer of the dishwasher consists of a synchronous motor and various switches, and controls the
various operations of the dishwasher automatically. The step motor, like a clock, runs at constant speed.
When it passes through the selected procedure, the internal switches will open or close at a precise
sequence, realizing the control of the circuit over the internal components.

The output cords of the timer are in different colors. With a copy of the circuit diagram in hand, you can
track the circuit from the timer to any element.

The timer is a very reliable unit. In case of dishwasher troubles, check other causes first before focusing
on and replacing the timer.

Steps for the check:

The option switch and power switch are push-button switches. Abrasion and use after an extensive period
may cause switch failure. When the switch is pressed, the power or high temperature pilot will not light up.
Check the power switch or the option switch.
Steps for the check:

Turn all the switches to OFF and pull out the power cord plug.
Remove the outer casing.
Press the power or option switch and check with an ohmmeter whether the normally open terminal
is closed. If it is not closed, replace the switch.
Remove the control panel, unscrew the screws to remove the defect switch, and replace with a new
one.
Connect the wires behind the switch and check if they are connected fast.
Replace the control panel and the outer casing.

The pressurecontrol of the dishwasher is realized through a float pressure switch composed of two micro
switches. The larger contact current (10A) controls the working level and the smaller current (3A) controls
the protection level. The working level is set at 78 85mm above the sump bottom, and the protection level
is 3mm or more below the brink of the inner container.
The check and adjustment of the pressure switch:

If pressure switch trouble is suspected, check whether the dishwasher is set level. If it is in level

position, remove the outer casing.
Add water to the inner container, and check whether the float and lever is choked. In case of

choking, correct it.
If the working pressure switch remains placid when the pressurein the water tank rises over 94mm,

the switch might be obstructed by the lever or damaged. In case of damaged switch, replace it.

XI. Inlet Valve

The inlet valve controls the water volume into the dishwasher. The electromagnetic valve is fixed on the
valve base. When it is powered, a magnetic field will come and pull the valve core to let in the water.

The feeding of the water depends on the timer, which controls the opening of the electromagnetic valve.
In normal circumstance, the pressurein the inner container of the dishwasher shall be 78 85mm above the

sump bottom. Open the door to check the pressurewhen water is filled.
During the washing operation, the inlet valve may open to add some water.
Steps for the check:
Check and replace the inlet valve.
a. Turn the power of the dishwasher to OFF, and pull out the power cord plug (guard against sharp edge

from hurting the power cord).
b. Check with an ohmmeter as instructed.
c. Remove the outer casing and the rear panel.
d. Check the connecting wire of the inlet valve for looseness and the valve for crevice.
e. Check the connection of the inlet hose.
f. If the incoming pressurein the water tank is lower than the normal level, remove the inlet hose, clean,

or, if necessary, replace the filter screen, and reconnect the inlet hose.
g. Check the inlet valve terminals with an ohmmeter. The probes should touch the terminals of the inlet

valve. If the pointer does not move, replace the inlet valve with a new one.
h. When replacing the inlet valve, turn down the water tap and remove the wedge and the connecting

tube.
j. Unscrew the screws in the inlet valve support (96), replace the inlet valve with a new one, and

reconnect the tube and wire. Connect the inlet hose when the dishwasher is ready.

XII. Protection Pressure Switch and Working Pressure Switch

Ø

6

If the protection pressure switch remain placid when the
pressurein the water tank approaches 2mm below the brink of
the inner container, the protection pressure switch might be
broken or dislocated due to loose mounting screws.

Tighten the mounting screws and adjust the protection pressure
switch as follows: (1)Short circuit the normally open terminal
and the common terminal of the working pressure switch;
(2)Unscrew the fastening screws in the adjusting plate of water
level; (3)Turn counterclockwise the adjusting screw in the
adjusting plate of pressuretill the required water level;
(4)Remove the short circuit cord on the working pressure switch,
and wrench tight the fastening screws in the adjusting plate of
water level.

Try the pressureagain. If the pressureis higher than expected,
go over again the adjustment above till the requirement is met.
After adjustment, seal the screws with thread gum. Otherwise,
the screws may get loose, causing the pressureto change.

XIII. Water Pump Motor Assembly

XIV. Heating Element and Protective Thermostat

The heating element is located in the sump. When it is powered in the heated washing cycle, it warms up
the water, which will clean the dishes more effectively, and generates heat after washing to dry the
dishes.

The heating element has a nichrome filament inside. You can measure the resistance with a universal
meter to check its condition.

The protective thermostat is a temperature limitation switch and a safety device. In case the dishwasher
fails and the temperature inside the inner container rises above a specific limitation, the thermostat will
cut the heating element circuit to avoid any damage to the machine.

Steps for the check:
Remove the outer casing.
From the left side, you can see the heating element assembly installed to the end of the sump. Pull out

the connecting terminal of the heating element.
Check the heating element with an ohmmeter for damage and replace the damaged one.

XVI. Water Temperature Thermostat

This thermostat (47) is designed to inspect the water temperature and control the heating element. The
temperature control point is set at 62 (different temperatures are available and can be observed from the
thermostat). The circuit is opened below this temperature and closed above it.
Steps for the check:

Remove the outer casing and bottom pan.

Remove the connecting wires behind the sump and check with an ohmmeter whether the thermostat

circuit is opened in normal temperature and closed when temperature rises above 67 . If the result if

positive, the thermostat is normal. Otherwise, it fails and shall be replaced.

Remove the screws and the mounting plate.

Replace a new thermostat and the mounting plate. The mounting plate shall press tight to prevent

water leakage at the thermostat end.

Replace the connecting wires, bottom pan and outer casing.

The dispenser (32) releases automatically the brightness liquid into the machine at the final rinsing stage.
The brightness liquid reduces the surface tension of the water and eliminates dirty spots from the dish
surface.

The dispenser can hold brightness liquid for one month use. At the final rinsing stage, the timer activates
the electromagnetic valve of the dispenser and pulls the rubber gasket of the valve core to release a
suitable amount of brightness liquid, which is carried away in the flowing water.

Steps for the check:

Check and replace the dispenser.

a. Turn the power switch to OFF, and pull out the power cord. Guard against sharp edge from cutting the

power cord.

b. Open the door, remove the four screws in the sides of the inner door, unscrew the knob cap of the

dispenser and the two locknuts, and remove the inner door.

c. Check the dispenser for any leakage or release of brightness liquid. If no brightness liquid is released,

check if there is brightness liquid in the dispenser. If there is brightness liquid in the dispenser, check
the terminals connected to the dispenser for looseness and fallout.

d. Pull out the two terminals of the connecting wire connected to the dispenser and remove the dispenser.

e. Check the electromagnetic valve of the dispenser with an ohmmeter. If the dispenser is broken,

replace it.
