SCREW
Installing Place
Install the washer on a horizontal solid floor. If the washer is
installed on an unsuitable floor,
it could make considerable
noise and vibration.
Keep the machine body more
than 25cm apart from the wall
surface. It will make easy cleaning the drain filter which is
equipped at the back side of it.
And if it comes into contract

vibration may occur.
-DWF-5510/5511/5010/6011
Never install in these places
¡ The place where it would be
exposed to direct sunlight.
¡ The place nearby a heater or heat
appliance.
¡ The place where it would be sup-
posed to be frozen in winter.
¡ The kitchen with coal gas and a
damp place like a bathroom.
1 Before installing your
washer, remove the
pad from the bottom
of the cabinet. Then,
separate under cover
from rear side of cabinet by unscrewing
and insert it into the
base.
2 Push the under-base
cover into the end, which
decrease the noise made
by this washer.

6. FEATURE AND TECHNICAL EXPLANATION
Feature of the Washing Machine
1 The first air bubble washing system in the world.
2 Quiet washing through the innovational low-noise design.
3 The wash effectiveness is much more enhanced because of the air bubble washing system.
4 The laundry detergent dissolves well in water because of the air bubble washing system.
5 The adoption of the water currents to adjust the unbalanced load.
6 One-touch operation system.
Water Current to Adjust the Unbalanced Load
It is a function to prevent eccentricity of the clothes after wash by rotating pulsator C.W and C.C.W for 35
seconds.(But, the SUIT course have no operation of the water currents to adjust the unbalnced load.)
EFFECT
It reduces vibration and noise effectively while spinning.

Automatic Water Supply System For Blanket Wash
The water level would be lowered because the blanket absorbs water at the beginning of washing. Therefore, after
60 seconds, the operation is interrupted to check the water level, and then the water is supplied again until the selected water level is reached.
EXPLANATION
11
Pulsator System
When the pulsator is rotated C.W or C.C.W at a high speed, it makes the cyclone water flow from the asymmetrically
designed pulsator as shown below.
Asymmetrically designed pulsator
makes the cyclone water flow, which get
rid of the washing dead zone to
increase the washing effect and reduce
the entanglement of laundry.
Automatic Drainning time Adjustment
This system adjusts the draining time automatically according to the draining condition.

2 In case of continuous draining, residual drain time is determined by micom.
Draining time as a whole = D + 30
Good draining The washer begins spin process after drainage.
Bad draining Draininig time is prolonged.

Softener Dispenser
This is the device to dispense the softener automatically by centrifugal force.
This is installed inside the auto-balancer.
FUNCTIONAL PRINCIPLE
1 Softener stays in room (A) when poured into softener inlet.
2 Softener moves from (A) to (B) by centrifugal force during intermittent spin process.
3 Softener flows from (B) to (C) during rinse process next to intermittent spin.
4 Softener moves from (C) to (D) by centrigfugal force during second intermittent spin.
After spin process is finished, the softener is added into the tub through softener outlet.

Automatic Unbalance Adjustment
This system is to prevent abnormal vibration during intermittent spin and spin process.
FUNCTIONAL PRINCIPLE
1 When the lid is closed, the safety switch
contact is “ON” position.
2 In case that wash loads get uneven during
spin, the outer tub hits the safety switch
due to the serious vibration, and the spin
process is interrupted.
3 In case that P.C.B. ASS’Y gets “OFF” signal
from the safety switch, spin process are
stopped and rinse process is started automatically by P.C.B. ASS’Y.
4 If the safety switch is operated due to the
unbalance of the tub, the program is
stopped and the alarm is given.
NOTES
The alarm finished when you close the lid after opening
it. Check the unbalance of the wash load and the installation condition.

Circulating-Water Course and Lint Filter
CIRCULATING-WATER
The washing and rinsing effects have been
improved by adopting the water system in
which water in the tub is circulated in a
designed pattern.
When the pulsator rotates during the washing
or rinsing process, the water below the pulsator vanes creates a water currents as shown
in figure.
The water is then discharged from the upper
part of the tub through the water channel.
About 40 L/min. water is circulated at the ‘high’
water level, standard wash load and standard
water currents.

Lint Filter
Much lint may be obtained according to the kind of
clothes to be washed and some of the lint may also

To minimize this possibility a lint filter is provided on
the upper part of the tub to filter the wash water as it
is discharged from the water channel. It is good to
use the lint filter during washing.

HOW TO REPLACE LINT FILTER

FUNCTIONAL PRINCIPLE
1 When the DRAIN MOTOR connected to the power source, the DRAIN MOTOR rotates with 900 r.p.m and
revolves the pulley by gear assembly for reducing.
2 When the pulley is rotated, the pulley winds the wire to open the drain valve.
3 Therefore, rotation of pulley changed to the linear moving of wire.
4 The wire pulls the brake lever of Gear Mechanism Ass’y within 5 seconds.
5 After the wire pulled, gear assembly is separated from motor and condition of pulling is held by operation of the
lever.
6 When the power is turned off, the drain valve is closed because the wire returns to original position.

9. PRESENTATION OF THE P.C.B ASS’Y
Concerning Error Message
MESSAGE CAUSE SOLUTION
Improper installation of drain hose.
The drain hose is blocked up by foreign
matter.
Drain motor is inferior.
The water tap is closed.
The water inlet filter clogged.
It passes over the 30 minutes, yet it doesn’t
come to assigned water level.
Wash loads get uneven during spin.
Poor installation of the unit.
The lid is opened.
The safety switch is inferior.
Install drain hose properly.
Remove foreign matter from drain hose.
Change drain motor.
Open the water tap.
Clean the water inlet filter.
Check whether or not is comes to the
