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.

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

Circle

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.

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

The warning buzzer

will sound and the

digital display will

indicate the error.

(Warning alarm

condition)

Stops while

operating process.

During the process,

WASH, RINSE and

SPIN button does

not operate.

START/HOLD

button does not

operate.

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.

(Part No. 42T40017)

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

At end of rinse or

washing operation,

reverse rotation

period is short.

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.

Make sure whether it is

placed on a firm and flat

floor.

Same as 5 - (2).

A gap should

be more than 3 cm.
