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.
51. (00110011) Diverter Valve Fault
The motor controller has registered a drop in water level in the recirculation phase of the
wash cycle. Water is being drained instead of recirculated.

Secondary Source: Motor Control Module.
Action:
52. (00110100) Diverter Top-up Fault
More than 6 attempts have been made to top-up the water level in the basket. This then
signifies the valve has not closed and is diverting to drain, or the top-up was not increasing
quickly enough, suggesting the valve has a blockage and is also draining.
Primary Source:
Action:
Secondary Source: Wax solenoid
Action:
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 40 in that a
valid basket status could not be determined.
Primary Source:
Action:
Secondary Source: Mechanical.
Action:
Diverter valve.
Remove the diverter valve and check for blockages as well as
checking that the hinge mechanism on the valve hasn't broken.
Remove the hinge from the solenoid and check that the flap is free to
move. Check that water hasn't been sprayed onto the valve from an
external source and caused the solenoid to blow.
Turn the power off at the machine but leave the power on at the wall,
then measure the voltage across the terminals of the wax actuator. If
a reading of 230V is achieved, the motor controller has failed due to a
valve fault and both will need to be replaced.
Diverter valve.
Remove the diverter valve and check for blockages as well as
checking that the hinge mechanism on the valve hasn't broken.
Remove the hinge from the solenoid and check that the flap is free to
move.
Check the resistance of the wax solenoid. Also look for corrosion
(greenish deposit) on the terminals. Resistance range will be
between 0.7kΩ and 2.5kΩ. Resistance will depend on ambient
temperature and when the valve was last actuated. Anything outside
of these resistances and the valve should be automatically replaced.
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.
