(00110010) Hot Valve Faulty
The Motor Controller Module has measured a voltage from the valve diagnostic circuit that
indicates that the hot valve is faulty. Also the cold water valve could have low resistance. The
most likely cause is that the valve harness has not been connected correctly or the valves are open
circuit. See fault 48 for service procedure.
51.
(00110011) Diverter valve timeout fault
The machine has detected that the diverter valve is leaking water to the drain when it should be re-
circulating.
Check by waiting for re-circulating function and observing if water is coming from the drain hose.
Primary source
- Diverter valve
Action
- Check diverter valve continuity. If open circuit, replace diverter valve.
Secondary source
- Motor Controller Module (drive circuitry blown).
Action
- Replace Motor Controller Module
Tertiary source
- Diverter valve harness/connectors.
Action
- Replace bowl harness
52.
(00110100) Diverter valve top-up fault
The machine has exceeded the maximum number of "top-ups" during re-circulation. Check to see
if water is leaking from drain hose during re-circulation.
Primary source
- Diverter valve
Action
- Replace diverter valve
Secondary source
- Motor Controller Module
Action
– Replace Motor Controller Module
Tertiary source
- Diverter valve harness/connectors
Action
- Replace bowl harness
53.
(00110011) Rotor Position Sensor Step Fail
The Motor Controller Module has attempted a motor step test and has found that the motor has not
stepped in the correct direction. It has detected that the motor is connected and that the motor drive
is operational. The rotor position sensing system is at fault.
Primary Source
-Wiring.
Action
- Check the Rotor Position Harness for continuity and that the connectors are correctly to the
Rotor Position Sensor and the Motor Controller.
Secondary Source
-Rotor Position Sensor.
Action
- Check the Rotor Position Sensor patterns with a RPS Tester, if faulty fit a new Rotor
Position Sensor.
Tertiary Source
-Motor Controller Module.
Action
- Replace the Motor Controller Module.
