112. (01110000) Motor Current Sense Too High
This fault occurs if the Motor Control Module detects that the motor current has reached an
unrealistically high level for greater than 2 seconds. This suggests that the motor current
sense circuit is faulty.
Primary source:
Action:
113. (01110001) AC Pump Thermistor Short Circuit
The AC Pump thermistor has been detected as being short circuit. This means that the
Motor Control Module can no longer monitor AC pump Triac temperatures correctly.
Primary source:
Action:
133. (10000101) Repetitive Current Trip
The Motor Control Module has detected excess current in the motor or electronic switches.
This fault is a more severe occurrence than fault code 132 but has identical fault sources
and fault service procedure
136. (10001000) Motor Stall
The Motor Control Module has been unable to start the motor. Possible causes of this fault
are: Faulty motor harness, faulty or jammed motor, seized bearings or seals, faulty Motor
Control Module.
Primary Source:
Action:
Secondary Source: Motor.
Action:
Tertiary Source:
Action:
137 (10001001) Motor loss of a Phase
The Motor Control Module has detected the loss of one of the phases of the motor.
Possible causes of this fault are: Faulty motor harness, an open circuit winding of motor or
faulty motor controller.
Primary Source:
Action:
Secondary Source: Motor.
Action:
Tertiary Source:
Action:
160. (10100000) Basket Engaged In Agitate
The basket has re-engaged itself during agitate. Possible causes for this are a leak in the
air bell, the basket is over-loaded with clothes, the clutch has jammed or is fouled with a
foreign object.
Primary Source:
Motor Control Module.
Replace Motor Control Module.
Motor Control Module.
Replace Motor Control Module.
Wiring.
Measure/check the motor harness, connectors and motor for
continuity. This can be done by taking a resistance measurement
between phases of the motor harness at the Motor Control Module
end. Nominal resistance should be around 39Ω.
1) Check free rotation of the agitator and basket by rotating by hand.
Bearings and seals may be seized.
Motor Control Module.
If the primary and secondary checks pass inspection, then replace
the Motor Control Module.
Wiring
Measure/check the motor harness, connectors and motor for
continuity. This can be done by taking a resistance measurement
between phases of the motor harness at the Motor Control Module
end. Nominal resistance should be around 39Ω.
Remove Stator and measure/check the resistance of each winding
which is approximately 19.5Ω.
Motor Control Module.
If the primary and secondary checks pass inspection, then replace
the Motor Control Module.
