Cold Valve Faulty; Hot Valve Faulty; Diverter Valve Fault; Diverter Top-Up Fault - Fisher & Paykel SmartDrive Service Manual

49. (00110001) Phase 2 to 6 - Cold Valve 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) Phase 2 to 6 - Hot Valve 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.
Note: Phase 5 can give a fault code 50 when the SmartDrive powers
off while spinning. There will actually be no fault if this has happened.

Secondary Source: Check for blockage in the valve itself or a
52. (00110100) Phase 5 and 6 Eco - Diverter Top-up
More than 6 attempts to top-up the water level in the bowl. 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.
The Motor Control Module has registered a drop
in water level in the recirculation phase of the
wash cycle, water is being drained instead of
recirculated. Or water has been sprayed onto
the Valve from an external source and caused
the solenoid to blow.
Turn the power off at the SmartDrive 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
Control Module has failed due to the valve and
both will need to be replaced.

Diverter valve.
Remove the diverter valve and check for
blockages or broken hinge mechanism.
