Display Eeprom Check; Hot And Cold Valve Faulty - Fisher & Paykel SmartDrive Service Manual

46. (00101110) Phase 5 IW - Display EEPROM Check
The Intuitive Display has detected a problem with its internal
EEPROM.

Action:
47. (00101111) Phase 2 and 3 - Bowl Dis-engage Fault
While carrying out a bowl check, the Motor Control Module has found
that the bowl is not engaged even though the pressure sensor
indicates that the bowl is empty. The Motor Control Module continues
to check for 2 minutes. During this time the module has not been able
to determine a valid bowl status and so displays this fault. This fault
differs from fault 40 in that a valid bowl status could not be
determined. The first two areas to check are the clutch and the
pressure tube. If these two appear correct, then the fault could be
with the pressure sensor in the Motor Control Module.

48. (00110000) Phase 2 to 6 - Hot and Cold Valve Faulty
The Motor Control Module has measured voltages from the valve
diagnostic circuit that indicate both the hot and cold valves are faulty.
The most likely cause is that the valve harnesses have not been
connected correctly or the valve is open circuit.
