BASIS
1.Connector to the PRESSURE S/W
ASM or RED 4 pin connector to
P.W.B ASM has bad connection.
2.PRESSURE S/W is bad. (In the
initial state of QC TEST MODE,
the number on the DISPLAY is
less than 60 or more than 104)
1. Check blockage in air hole of
outer tub or pressure air tube.
2. Check air leakage at the air
hole of outer tub or pressure air
tube.
1. Connector the HALL Sensor or
Blue 4 Pin connector to P.W.B
ASM had bad connection.
2. Connector the stator ASM, and
YELLOW 3 Pin or Natural 6 Pin
connector to P.W.B ASM had
bad connection
3. Hall sensor is bad.
4. Locked by Bearing Housing
1. Connector to the Clutch Motor or
BLUE 3 Pin connector to P.W.B
ASM had bad connection.
2. Bad Clutch Motor.
Check whether the coupling of
Bearing Housing ASM has
broken.
1. Connector to the Break Resistor
or GRAY 2 Pin connector to
P.W.B ASM had bad connection
2. Check whether the Brake
Resistor has broken
3. Check whether P.W.B ASM has
broken
