Spending time for water supply and water drain depends on water pressure and draining condition.
Generally, spending time for water supply is about 4 08 (for High level), and for water drain is about 2 .
Standard time of Custom course is the same at of Normal course.
Drainage: After the water is left at the RESET water level (level of water level sensor gets reset) the spending time of draining is about 1 .
Restarting Function: Washer can operate until the end of wash cycle interrupted by power failure if the electric power returns within 4 hours.
Normal and Soak course has been programmed with Shower rinsing. If the water flow volume is less than 5l/min., the washing machine automatically adds the water saver rinsing, so the remaining time will be changed from 11 to 23 minutes.

The washer begins rotating the Pulsator right then left two times to check the volume of the laundry and select the most suitable water level.
Water is supplied to the lowest water level LOW2.
The Pulsator rotates right and left in about 40 , in that time sensor will determine type of fabric and select the most suitable program, such as: Spinning time, Washing time, Rinsing mode, water flow
Water is supplied to the selected water level.
In Soak course, the laundry is soaked for 45 minutes. During the soaking, Pulsator will rotate intermittently 5 minutes per cycle to stir the laundry.
Within 40 seconds from washing process, Pulsator rotates to create flow water to confirm water level.
40 seconds after starting washing, Pulsator stops in 4 seconds to check the water level, if the water level is lower, the program will automatically supply the water until the selected water level is reached
1 minute after starting washing process, sensor will receive the signals from revolution of laundry. Responding to the revolution of laundry, microchip will determine the most suitable water flows.
1 before completion of washing process, Pulsator will rotate to create laundry disentanglement flow water.
After water level reaches reset point, draining course continues for 1 40 .
In the first spinning, washer carries out 1 10 ON intermittent spin dry cycle.
Before completion of spinning, electrical continuity of motor breaks off and motor rotates continuously by inertia. The Brake
Ass y activates while Spin Tub revolution speed is slowing down.
During Spinning: If the clothes clump on one side or the Spin Tub becomes unbalanced, the microchip will detect the unbalance condition and automatically proceed the following corrective.
Water is supplied to the selected water level.
Water save rinse: Water is supplied to the selected water level responding to the wash load, Pulsator rotates and water supplying is stopped.
Overflow rinse: After water is supplied to the selected water level,
Pulsator rotates and water is continuously supplied.

13. Troube shooting of Bearing Assembly (Bearing Case Complete)
For Fully Automatic Washing Machines.
1.
Abnormal (Squeaky) sound is heard during washing:
Symptom: The squeaky sound occurs when the brake system operates. During washing, the Pulsator turns
CW (clockwise) and CCW (counterclockwise), producing water flow in the CW and CCW direction. The water flow exerts force on the Spin Tub in the same directions though interlocked with the Brake Wheel during washing. The Spin Tub turns a little if the friction with the brake lining reduces, generating braking sound. This symptom will not arise due to use of long duration but is entirely an initial fault.
Diagnosis: Turn off the power. Open the Washer Lid. Hold the Spin Tub and lightly turn it CW. If sound is heard from the brake, it is defective.
Cause: The cause can be limited to foreign substance (grease in particular) affixed to the surface of brake lining and brake wheel, which is attributed to poor quality control in the Bearing Assembly manufacturing process.
Handling: Replace the Bearing Case (complete) and wipe the Brake Wheel surface with alcohol.
2.
Spin tub stops sound (squeak):
Symptom: Squeaky sound is heard immediately before the Spin Tub stops.
Cause: This symptom often arises when friction factor between brake lining and brake wheel is too big.
Therefore, this occurs when brake time is short, the cause of which is attributed mainly to the improperness of brake lining material, roughness of brake wheel surface and excessive strength of brake spring, but attachment of foreign matter and high humidity can also be responsible for the symptom.
Diagnosis: Allow water extraction program to complete automatically instead of forcibly, apply the brake, and listen for squeaky sound when the Spin Tub stops.
Handling: Replace the Bearing Case (complete) and wipe the Brake Wheel surface with alcohol.
3.
Brake does not work:
Symptom: Brake is applied when water extraction has completed, but the Spin Tub takes too long time to come to a complete stop.
Cause: Braking torque is too small, which is attributed to excessive abrasion of brake lining, attachment of foreign substance (grease in particular) on the surface of brake wheel and brake lining, etc..
Diagnosis: Taking approx 10 sec. of braking time, which is normally about 5 sec, can be determined to be defective.
Handling: Replace the Bearing Case (complete) and wipe the Brake Wheel surface with alcohol.
4.
Abrupt braking (When the Spin Tub stops, the entire machine moves):
Symptom: Brake is applied when the water extraction has complete, but the Spin Tub takes a very short time to come to a complete stop.
Cause:
Braking torque is too big, which is attributed to abnormal shape of brake lining. This symptom occurs particularly when clearance between brake lining and brake wheel is too small at their tips.
Diagnosis: Taking only 2 or 3 sec. of braking time, which is normally about 5 sec at no load, can be determined to be defective.
Handling: Replace the Bearing Case (complete) and wipe the Brake Wheel surface with alcohol.
- 19 -
5.
Spin tub does not rotate (Spin Tub is locked):
Symptom: Spin Tub does not rotate despite water extraction starting stage.
Cause: When it is caused by electric signals, water level sensor, Magnetic Coil, motor receptacle
Housing Assembly, PCB Complete, Safety Switch, etc are likely to response. However, the troubles are mainly caused by related mechanical parts in this case. If this problem occurs, the clutch mechanism of Bearing Ass y will fail. Especially, one-way bearing, which composes part of Bearing Case (complete), rusted by detergent penetrating is the main cause of the trouble.
Insufficient transfer of rotation due to inaccurate dimensions of clutch spring also causes the trouble.
Diagnosis: Assuming that all electric parts are normal, check if the Spin Tub can be easily rotated by hand when the Magnetic Coil is in the state of pulling.
Handling: Replace the Bearing Case (complete) and wipe the Brake Wheel surface clean with alcohol, or replace the Clutch Spring.
6.
Water leakage:
Symptom: Water leaks from somewhere around the Bearing Ass y. Parts of the Bearing are sometimes seen rusted.
Cause: Oil seal lip lying on the top of ring (complete) is insufficiently fitted in the Outer Tub Bottom.
Handling: Replace the Bearing Ass y.
7.
Click sound is heard during washing:
Symptom: Click sound is heard from the vicinity of the Bearing Ass y. Similar sound can also be caused by a small metal piece, such as a coin or hair pin penetrating into the back of the Pulsator, damaging and making its rear ribs into flakes and resultantly generating sound. This will not be discussed here because there is nothing to do with the Bearing Ass y.
Cause: Infusion engagement of the Clutch Lever with the ratchet causes the lever to jump, making noises. In the washing process, the Clutch Lever is normally engaged with the ratchet completely, generating no sound.
Diagnosis: Normally the clearance between the circumference of the ratchet and clutch lever is approximately 3 mm. In the event of this trouble, the clearance should be 5 to 6 mm.
Handling: Replace the Bearing Ass y
