Step 1

①Check deformation of Leg of Frame bottom.

- Leg-bottom Rubber is damaged.

- Right angle is not maintained due to Leg Bolt

deformation.

②Adjust level installation of leg & inspect place

of installation.

- Refer to Level Product Installation Guide Tip 1-3.

Step 2

①Check Spin mode.

- Press Soil+Signal+Power to enter the

Test mode.

- Turn knob and select “SPn” to start.

- Check if Spin reaches Extra-High LED.

②Check Unbalance Test.

- Run Spin Test with 300g placed on one side

unbalanced.

※ 300g – 2 Towels OR Jig for this purpose only

- Check for abnormal noise & Set moving.

Step 3

①Oil leakage of Balancer

- Rotate Spin-Basket to check frictional noise

between balls.

※ If the frictional noise is dull, it is regarded as OK.

②Abrasion of Weight-Balancer

- Check if Weight-Balancer shakes.

- Gap is created if the screw head of fixing bolt wears

out.

- Couple more OR replace it.

③Check the concentration of Spin-Basket.

- Check if Spin-Basket moves up and down.

- Check if Spin-Basket vibrates due to broken fixing

bolt.

※ After SVC, explain to the customer how to use it.

①Check the use condition of Customer.

- Check if moisture-proof cloth is used.

: Water–Proof Sheet, Mats, clothing

Check Point Spin-Basket / Check the user environment condition.

Tip 1-1. Frame & Spin-Basket Abnormality

- 5/39 -

Step 1

①Check Tub for abnormal noise.

- Shake the Tub back and forth to check where the

noise is coming from.

②Hanger Spring connection & Grease application

condition

- Check if grease is properly applied between

Hanger Spring and Hanger Guide friction part.

Step 2

①Check if Damper is separated or unassembled.

- If the bolts connecting damper

- If the dampers are rusted or not fastening,

☞replace.

②Check the condition of loosening of Damper

connection.

- The shape of connected part of Bottom-Plate is

defective, and thus it does not rotate properly.

- It does not rotate properly because it was

connected too much in the assembling process.

☞When it does not rotate properly, “Dda-dda-dda”

noise is generated due to friction between Damper &

Bottom-Plate. Thus, do as in ③.

③What to do when Damper connection is

loosened.

- Add Nut M10.

- Product Name: Nut-Hexagon (6021-001588)

※ Damper connecting force : 250 ~ 350kgf.㎠

Check Point Check the operating condition of Damper.

Tip 1-2. Damper & Hanger Abnormality

- 6/39 -

Step 1

①Check if there are any shipping bolts

on the back of washer.

Shipping bolts should be removed & kept.

②When installing, check the frictional relationship

with the surroundings.

- Install a pair of dryers together, causing

interferential noise when the Frame shakes

during spinning mode.

③Check the installation levelness & Floor-moving

phenomenon.

Case #1 - The levelness, which is measured with

levelness-measuring apparatus, is poor.

Case #2 –It shakes due to old floor (lumber) of

laundry room.

☞Re-installation is recommended so that it does not

influence on vibration.

Step 2

①Check if pedestal is installed properly.

- In case of old pedestal, check if all bolts

connecting washer and pedestal are

tightened properly.

②Condition of levelness of Leg installation

- If the rubber of legs is damaged, replace it.

- Lower leg is better for vibration.

Shorten the leg height and lock up the legs

after adjustment.

- Check if washer inclines to one side and

level washer again with adjustment of legs.

③Environment with slippery floor (Tile, Moisture)

- Attach on-Slip Pad.

④Material which is inappropriate for Leg floor

according to rules.

Case#1 Frictional noise of Pan Drain

Case#2 Use floor protection as sub-material for the

Leg bottom.

☞Re-installation is recommended so that it does

not influence on vibration.

Check Point Check the installation place and stability condition.

Step 1

①Assembly Bolt of Washing Motor

- Check the assembly status of the bolt.

If the bolt is loose, tighten it.

②When there is abnormal noise, have the

Rotor disassembled for checking.

- When the weight sensor is operating, check

for frictional noise of washing motor while

Motor-L / Motor-R is rotating.

- Remove iron foreign substance, if any,

absorbed by Rotor Magnetic.

Step 2

①Jet Engine noise during spinning mode

- Push Soil+Signal+Power to enter the Test

mode.

- Turn knob and select “SPn” to start.

- Check if Extra-High LED of Spin is reached.

☞If the tub is rotating empty without load,

check the roaring sound during high-speed

rotation.

②In the case of abnormal noise or Bearing

abnormality, replace Tub-back.

Step 3

①Check frictional noise between parts of

Frame.

- Shake the Tub back and forth to check where

the noise is coming from.

②Inspect the main parts from which noise is

generated.

- Add sponge to frictional part of Frame-Front.

☞Add more sponge to noise-generating part.

Check Point Check the operating condition of shafting.

Tip 1-4. Shafting Abnormality

- 8/39 -

Step 1

①Rotor with your hand and check the gap

- If the gap is not the same as in the photo

right,

- it could cause noise during the spin cycle

②Check if Motor Wire Pin fell out

- photo of pin which had fallen out added

- Must check regarding contact fail caused by

the opening of Pin inside the terminal.

Step 2

①Check of Resistance motor (U-V-W).

☞The Resistance : approximately 11Ω

②Check the Hall Sensor.

- Check of ⓐ-VCC(PNK) and ⓓ-GND(ORG)

☞The Voltage : approximately 5.0V

- Check of ⓑ-U(RED)/ⓒ-V(BLU) and ⓓ-

GND(ORG)

☞The Voltage : approximately 0~1.2v Pulse

※ Rotor the slow turning by manually

☞Replace the Motor

Check Point Check the operating condition of Motor.

Tip 1-5. Motor Abnormality

※ⓑ/ⓒ:0↔1.2v

- 9/39 -

Step 1

①Mechanical Friction Noise

- When pump drain is operating,

it vibrates a little. If drain parts such as

drain hose are near other parts, it may

cause mechanical friction noise.

Step 2

①Foreign materials in Pump Drain

- Open debris filter and check there are

foreign materials such as coins, pins etc.

②Check pump drain impeller is broken.

Step 3

①Check if the fixing part of Pump-Case is loosened.

- Check if the two bolts fixing Frame-Plate bottom

are loosened.

- Check if the fixing part of Pump-Case front is

loosened.

☞Assemble the Pump-Case again.

②One assembly part of Pump-Case front is loosened.

- Frictional noise is generated due to vibrating up

and down.

☞Assemble Pump-Case again.

Check Point Check the condition of Pump-Drain.

Tip 1-6. Pump Noise Abnormality

- 10/39 -

Step 1

※ Explain to NDF customer.

- Check the wrong usage condition of laundry

and explain recommended usage.

- Do not use Water–Proof Sheet, Mats and

clothing.

Step 2

①Resonance phenomenon occurs in the rising

section during spinning mode.

- Resonance Frequency: 200~450rpm section

- In the resonance frequency, Tub moves.

※ It is a resonance phenomenon occurring in

the rpm rising section for water extraction at

the beginning, which is normal.

②Ball friction occurs when Spin-Basket

rotates in low speed.

- Explain that the frictional noise from the Ball,

which is the center of gravity in the Balancer,

is normal.

※ If the Ball in the Balancer makes strong

frictional noise while checking Tub, then it

means that the oil is leaking. Thus, replace

Spin-Basket.

Check Point Explain the NDF and product characteristics.

Tip 1-7. Explanation of NDF and product characteristics

Step 1 : Small Loads Case

: If loading the laundry whose weight is 1kg ±

0.5kg, it is easily inclined to one side.

☞Add more laundry to make it normal.

Step 2 : Unbalance of laundry

: Stop using Water–Proof Sheet, Mats and clothing.

☞Do not input the laundry listed above, since

water does not drain during high-speed spinning

mode, causing unbalance problems.

Step 3 : Unbalance of bedding, carpet, and etc.

: Bedding should be washed alone less than 3.5kg.

☞Solution: Roll up the bedding before putting

into washer.

※ Do not wash Cotton bedding, wool bedding

and mink blanket.
