Common Check Items When A Dd Motor-Related Error Occurred - Toshiba AW-SD150SBA Service Manual

Common check items when a DD
motor-related error occurred
E6, E7, E8 & Ec errors are the errors occurred by excessive washing load, too low water level for the washing load,
rotation sensor failure, clutch sensor failure, defective operation or failure of clutch mechanism, drain valve motor
failure, electronic unit failure, incomplete contact of in-machine wiring and wire disconnection.
Depending on the detecting situation, error display may not always be the same even when a deficiency occurred on
the same place. Please check the operation of the motor and clutch following the procedures shown below.
Are clothes more than the rated load put in the machine?
Is water level set lower for the washing load?
Turn off the power and take clothes out of the machine.
Check the clutch sensor position according to the detailed failure diagnosis method. (Page 2 )
Wash side
Check if the spin tub is rotated manually and locked.
Locked (wash side)
Check <A>
Rotate the pulsator by hand
to check the input of the
rotation sensor signal.

Spin side
Manually rotate the spin tub in clockwise and
counterclockwise direction.
(Switch the clutch to the wash side manually.)
Was the clutch input switched to the wash side?
It still remains at the spin side.
