38. (00100110) Pressure Sensor Fault
The Motor Control Module has detected and recorded an empty water level while agitating.
The water level must have been greater than empty for the machine to start agitating
initially.

Secondary Source: Motor Control Module.
Action:
39. (00100111) Pressure Tube Fault
The Motor Control Module has detected a fault with the pressure tube.
Primary Source:
Action:
Secondary Source: Motor Control Module pressure sensor.
Action:
40. (00101000) Basket Dis-engage Fault
While carrying out a basket check, the Motor Control Module has found that the basket is
not engaged even though the pressure sensor indicates that the basket 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.

Secondary Source: Motor Control Module.
Action:
41. (00101001) Temperature Sensor Fault (Thermistor)
The temperature sensor is measuring temperatures above 230
likely due to a short circuit in the sensor line.
Primary Source:
Action:
45. (00101101) Display Memory Check Fault
On power up, the display has checked its memory against a known reference and found
differences.
Primary Source:
Action:
46. (00101110) Display Memory EEPROM Check
The Intuitive™ Display has detected a problem with its internal EEPROM.
Primary Source:
Action:
Mechanical.
Check the pressure tube is attached and has not been cut.
Replace the Motor Control Module, if the pressure tube shows no
sign of being faulty.
Mechanical.
Check that the pressure tube is not blocked with water or dirt, is not
kinked and it attached securely.
Replace the Motor Control Module.
Mechanical.
1) Check that there are no clothes or other foreign objects preventing
the clutch from re-engaging. Excessive suds can stop the basket
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.
Replace Motor Control Module.
Temperature Sensor (Thermistor).
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

@ 77 F (25 C) or 12.5kΩ @ 68
3) Replace the Motor Control Module.
