Pressure Tube Fault; Bowl Dis-Engage Fault; Temperature Sensor Fault (Thermistor); Display Memory Check Fault - Fisher & Paykel CleanSmart WL8060P1 Service Diagnostic Manual

Secondary Source: Motor Control Module.
Action:
Replace the Motor Control Module, if the pressure tube shows no sign of being faulty.

39. Pressure Tube Fault

The Motor Control Module has detected a fault with the pressure tube.
Primary Source: Mechanical.
Action:
Check that the pressure tube is not blocked with water or dirt, is not kinked and it attached
securely.
Secondary Source: Motor Control Module pressure sensor.
Action: Replace the Motor Control Module.

40. 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, after which time it displays this fault. The first two areas
to check are the clutch and the pressure tube. If these two appear correct, then the fault could be
in the pressure sensor in the Motor Control Module.
Primary Source: Mechanical.
Action:
1) Check that there are no clothes or other foreign objects preventing the clutch from re-engaging.
Excessive suds can stop the bowl rotating.
2) If the machine is empty of water, carry out a clutch disassembly procedure and check the spline
drive.
3) Next check that the pressure tube has not come off and that it is not kinked.
Secondary Source: Motor Control Module.
Action:
Replace Motor Control Module.

41. Temperature Sensor Fault (Thermistor)

The temperature sensor is measuring temperatures above 110°C. This fault is most likely due to a
short circuit in the sensor line.
Primary Source: Temperature Sensor (Thermistor).
Action:
1) Check the connection from the thermistor the Motor Control Module, especially check for a short
circuit.
2) Check the resistance of the thermistor. Resistance should be 10kΩ @ 25°C or 12.5kΩ @ 20°C.
Replace if faulty.
Replace the Motor Control Module.

45. Display Memory Check Fault

On power up, the display has checked its memory against a known reference and found
differences.
Primary Source: Display Module.
Action:
Replace Display Module.
