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
