xAfter the end of working, measure insulation resistance between the charging part
(power cord plug) and the non-charging metallic part (ground) with an insulation
resistance meter (500 V) and check the resistance is 10 MΩor more.
Failing to check the insulation resistance may cause a short circuit, an electric shock or other
diseases to the customer.
xDo not modify the product.
An electric shock or ignition may occur.
xOnly a repair technician can disassemble and repair.
An electric shock, ignition or malfunction may cause injury.
xUse an exclusive 110 VAC/15 A socket for the washing machine.
xUse an exclusive 220 VAC/17 A socket for the washing machine. (Except above models)
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.
xConnect 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.
xDo 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.
xDo not pour or immerse the electrical parts.
An electric shock or ignition may occur.
xWipe off the dust adhered to the plug of the power cord.
Dust may cause a fire.
xDo not put inflammable into washing tub.
Do not put cloths stained with kerosene, gasoline, benzene, thinner, alcohol. etc. It may cause
a fire or explosion.
xDo 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.

4. TECHNICAL POINT
4-1. EACH CYCLE SPECIFICATION
The asterisk (*) below denotes initial set-up.
•The time requirements listed above include a water supply rate of 15 L/min and a drainage time. The actual time required
varies according to the quality of the laundry, the degree of its offset, water pressure, and/or drainage status.
•Actual wash and spin may differ from operation time indicated by the process display.
•If load of the laundry is not balanced, the residual time may increase to correct this imbalance.

Adjust the legs so that the machine does not move.
1. After adjustment, lock the nuts of the legs by rotating them in the direction of the arrow (B).
Make sure so that the bottom of the main body front does not reach the floor.
If the bottom is in touch with the floor, then it will be the cause of shaking and abnormal noise.
Check the position of the air bubble in the floor level indicator.
2. If the bubble is not positioned inside the circle, adjust height by rotating the leg caps.
Depending on locations of the bubble in the horizontal level indicator, place caps and lock legs
(Make sure to fix adjustable legs.)
3. Mount the caps on the right-hand legs. Rotate the height adjust legs to perform height adjustments.
Hold down the diagonal line of the washing machine, and make sure that no wobbling occurs.
4. Despite the fact that the bubble is inside the circle, if the wobbling exists. Then shaking motion becomes
larger or some abnormal noise comes out. Make sure to readjust in case the washing machine wobbles.
5. INSTALLATION

Note: Check the floor level
Indicator directly from above.
NOTE: The machine comes with four leg caps: two for adjustment in steps of 3 mm, and two for adjustment in
steps of 6 mm. Use them in combination as required. If they are to be stacked, position the thicker
caps under thinner ones.
Tighten nuts of adjustable
legs, and lock them.

When checking trouble or repairing, keep to the following items.
(1) Unplug the power cord and wait for 5 seconds before starting the operation (the capacitor of large
capacity is used).
(2) The static electricity charged on plastic parts of the machine or on the human body may cause damage to
the electronic parts. Wear a ground ring or touch the two short plug pins together and the ground wire or
ground pin once to discharge the electric potential difference between the human body and the washing
machine when repairing the program timer
(3) As program timer is covered by moistureproof coating, parts in the electronic timer can not be replaced.
Please change the whole unit of the program timer. Also, do not damage the moistureproof coating.
(4) As live high (see as below) and low (DC17 V) voltage are mixed inside the panel plate, pay attention not
to touch the parts.
(5) The radiator plate of the program timer is hot immediately after the operation. Take care not to suffer
burns.

7-3. NO PROBLEM DIAGNOSIS
Please check the following.
Check Point
Refer to pages 12 to 13.
(1) Whether it is warning alarm condition as 1
(2) Whether it is set to no spin process with pressing on SPIN
button. (When no spin process is selected, the pulsator
stops at the end of last rinse operation without draining.)
(1) Whether the WASH, RINSE and SPIN button is pushed
after beginning the operation.
(2) Whether it is changed process while operating rinse and/
or spin process.
Whether it is set to preset.
(1) Whether it is set to no spin process with pressing on SPIN
button
(2) Whether the drain hose is at
proper height.
(Whether it is warning alarm
condition.)
(3) Whether too long extension hose
is used.
(Whether it is warning alarm
condition.)
(4) Whether a slender extension
hose ϕ 25 which is not Toshiba’s
option is used.
(Whether it is warning alarm
condition.)
Diagnosis
1
The warning buzzer
will sound and the
digital display will
indicate the error.
(Warning alarm
condition)
2
Stops while
operating process.
3
During the process,
WASH, RINSE and
SPIN button does
not operate.
4
START/HOLD
button does not
operate.
5
Poor drain
No drain
Hard to drain
Remedy
Refer to pages 12 to 13.
Same as 1
Press the COURSE button
only, then will be operated
automatically from washing
to spinning.
Press the START/HOLD
button, then set again.
This is not trouble.
Turn off the power switch
and reset.
This is not trouble.
Turn off the power switch
and cancel preset.
Same as 2- (2).
Set the hose height less
than 15 cm.
Use less than 3.0 m hose
on flat surface.
Replace it to Toshiba’s
optional extension hose.

Check Point
(5) Whether the drain hose is connected to the drain pipe
tightly. (Whether it is warning alarm condition.)
(6) Whether the drain hose collapses.
(Whether it is warning alarm condition.)
(7) Whether the drain hose is blocked.
(Whether it is warning alarm condition.)
Note:
Keep the gap between the top of the rubber pipe and the
washer pan.
At washing and rinsing process, reverse rotation is performed
to loosen fixed clothes for the last 20 sec.
(1) Whether automatic correction mode for uneven loading is
performed during operation.
(As the procedure (water supplying-stirring <1 min.> -
drainning) is automatically performed, if the fixed clothes
are loaded unevenly, the total operation time is prolonged.)
(2) Whether the drain hose is placed too high due to threshold,
etc.
[If the drain hose is placed too high, large volume of
bubbles are generated during the RINSE or SPIN process
and the spin speed does not increase properly. In such
case, [fill water →stirring time (1 min.) →drain] processes
are automatically activated, and the operation time will be
prolonged for these processes.]
Diagnosis
Poor drain
No drain
Hard to drain
6
At end of rinse or
washing operation,
reverse rotation
period is short.
7
Washing operating
time is longer than
usual.
Remedy
Make a gap.
Replace the drain hose if it
collapses.
Make a gap.
Cut the drain hose
obliquely.
This is not trouble.
This is not trouble.
Make sure whether it is
placed on a firm and flat
floor.
Same as 5- (2).
A gap should
be more than 3 cm.
