130. (10000010) Rotor Position Sensor Error
The Motor Control Module has found an error in the pattern received from the Rotor
Position Sensor. Likely causes of this fault are a bad connection on the harness between
the Rotor Position Sensor and the Motor Control Module, or a faulty Rotor Position Sensor.

Replace Motor Control Module.
Motor Control Module.
Replace Motor Control Module.
Wiring.
Check for corrosion on the RAST connector of the Rotor Position
Sensor and the Motor Control Module connector.
Check the Rotor Position Sensor with an R.P.S. tester. Replace if
faulty.
Motor Control Module.
Replace Motor Control Module.
Ensure the correct rotor for this series of machine has been fitted
(Refer to Section 4.8.2).
Wiring.
Measure/check the motor harness, connectors and motor for
discontinuity. 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 32Ω.
1) Check free rotation of the agitator and basket by rotating by hand.
Bearings and seals may be seized.
2) Check the Rotor Position Sensor and associated harness for
water, mechanical damage or corrosion.
Motor Control Module.
If the primary and secondary checks pass inspection, then replace
the Motor Control Module.
