48. (00110000) Hot and Cold Valve Coil Faulty
The Motor Controller module has measured voltages from the valve diagnostic circuit that
indicate both the hot and cold valves are faulty.

49. (00110001) Cold Valve Coil Faulty
The Motor Control Module has measured a voltage from the valve diagnostic circuit that
indicates the cold valve is faulty. The most likely cause is that the valve harness has not
been connected correctly or the valve is open circuit. See fault 48 for service procedure.
50. (00110010) Hot Valve Coil Faulty
The Motor Control Module has measured a voltage from the valve diagnostic circuit that
indicates the hot valve is faulty. The most likely cause is that the valve harness has not
been connected correctly or the valve is open circuit. See fault 48 for service procedure.
56. (00111000) Basket Check No Valid Fault
While carrying out a basket check, the machine has not been able to determine a valid
basket status and so the Display flags this fault. This fault differs from fault code 40 in that
a valid basket status could not be determined.

Action:
57. (00111001) Brown Out During Display EEPROM Write Fault
The Display has requested the Motor Control Module to perform an EEPROM write. Prior
to writing, the Motor Control Module has tested the 15 Volt supply and found that it is below
the safety level for writing EEPROM and has reported this to the Display. This may be due
to transients at the time of writing or due to a faulty Motor Control Module.
Primary Source:
Action:
Wiring.
Check the valve harnesses are correctly fastened to the valves or the
pins are not bent backwards.
Check the valve coils are not faulty (i.e. open circuit).
Motor Controller module.
Replace the Motor Controller module.
Loading.
Remove items until the remaining ones can move freely, or rearrange
the load so that the clothes are evenly distributed around the basket,
or select a higher water level. If the load was to one side of the
basket or too heavy, it can be possible for the agitator to bind in one
direction when trying to sense basket float.
1. Check the machine is not siphoning.
2. Check that there are no clothes or other foreign objects preventing
the clutch from re-engaging, and that there aren't any defects with
the clutch mechanism.
3. Check that the pressure tube has not come off and that it is not
kinked.
Rotor Position Sensor.
Replace the Rotor Position Sensor.
Replace the Motor Control Module.
Motor Control Module.
Replace Motor Control Module.
