Select the correct size on the display by pushing the White button next to the correct size (Phase 5) or using the ADJUST button to highlight the right size (Phase 6).
  • Page 25 The Motor Control Module has found the water level to be above the flood level and tried to pump the excess water out. (Under extremely high flow rate conditions the SmartDrive may overfill during the “top- up” routine in agitate.) After pumping for 30 seconds, it has been unable to lower the water level below the flood level.
  • Page 26 Primary Source: Display Module. Action: Replace the Display Module. Note: If SmartDrive is running at well below its rated supply voltage and the pump has operated for more than 4 seconds at the voltage, this fault will also appear. 17 – 20. (00010xxx)Phase 1 - Display / Motor Control Module Out of Sequence 22 –...
  • Page 27 Liquid Crystal Display. Primary Source: IW Display Module. Action: Replace IW Display Module. 28 – 30. (000111xx)Phase 1 - Display / Motor Control Module Out of Sequence Refer to fault code 17 32. (00100000) Phase 1 - Pump Circuit Error The Display Module has detected that the pump is on when it is off.
  • Page 28 4 times during agitate. This is excessive, as normally only one or two top ups are required to replace the air that has escaped from a full load during agitate. The most likely cause is that the SmartDrive is siphoning. The other alternative is that the SmartDrive has developed a leak.
  • Page 29 The third is that the pump is not operating due to Motor Control Module, wiring or pump failure. This fault could also appear if the SmartDrive is pumping to an unusually high head of drain hose or into an extended length of drain hose. The fourth possibility is a diverter valve fault or blockage.
  • Page 30 The Motor Control Module has recorded a water level of empty while it is agitating. The water level must have been greater than empty for the SmartDrive to enter the agitate mode initially. The most likely cause of this fault is that the pressure sensor hose has been severed or fallen off during agitate.
  • Page 31 Excessive suds can stop the bowl rotating. 2. If the SmartDrive 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.
  • Page 32 The Motor Control Module has had some confusing information feedback. Action: Turn off SmartDrive at the wall and back on again after 5 seconds. Restart. 43. (00101011) Phase 1 to 6 - OOB Switch Fault The Motor Control Module has found that the signal returning from the out of balance switch indicates that the switch is permanently on or the harness to it is disconnected.
  • Page 33 Also check that the drain hose is not blocked. 4. If the bowl contains water, then service the pump from the top of the SmartDrive by removing the top deck and inner bowl. Bail out the water, remove the pump cap and hood and clear the pump of any obstruction.
  • Page 34 46. (00101110) Phase 5 IW - Display EEPROM Check The Intuitive Display has detected a problem with its internal EEPROM. Primary Source: IW Display Module. Action: Replace IW Display Module. 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.
  • Page 35 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.
  • Page 36 Action: Check the resistance of the wax solenoid. Also look for corrosion on the terminals (greenie deposit). Resistance range will be between 0.7kΩ and 2.5kΩ. Values are dependant on ambient temp and when the valve was last actuated. Anything outside of these values and the diverter valve should be automatically replaced.
  • Page 37 Action: Check continuity of motor phases. Check the bridge terminal on the stator is not open circuit or burnt. Replace the stator. Tertiary Source: Motor Control Module. Action: Replace Motor Control Module. 55. (00110111) Phase 3 to 6 - System Step Fail Primary Source: Rotor Position Sensor.
  • Page 38 Phase 5 Primary Source: Rotor Position Sensor. Action: Replace the Rotor Position Sensor. Secondary Source: Loading. Action: Remove items until the remaining ones can move freely, or rearrange the load so that the clothes are evenly distributed around the bowl, or select a higher water level.
  • Page 39 58. (00111010) Phase 4 to 5 - Pressure Transducer at Maximum Adjustment Fault When the pause or delay start is pressed to start the SmartDrive, the Display Module has checked the memory and found the count greater than expected. Primary Source: Motor Control Module.
  • Page 40 63. (00111111) Phase 5 - Pump Comms Error The Motor Control Module has detected an internal communications problem between its main control system and the pump control system. Primary Source: Motor Control Module. Action: Replace Motor Control Module. 64. (01000000) Phase 5 and 6 - Pressure Transducer (Ptx) Error - Frequency <...
  • Page 41 105. (01101001) Phase 2 to 6 - Comms Error Time Out These faults are reported when the Display Module detects an error in the communications between the Display Module and the Motor Control Module. Note: If the product is an IW, the wrong Motor Control Module may have been fitted.
  • Page 42 106. (01101010) Phase 2 to 3 and 5 - Display to Motor Control Module Communications Errors (Phase 6 IW Also) These faults are reported when the Display Module detects an error in the communications between the Display Module and the Motor Control Module.

  • Page 43: Machine Set Up Error

    127. (01111111) Phase 5 - Machine Set up Error The Display Module has been fitted to the wrong model, size and or phase of SmartDrive, eg. Phase 5 Display Module cannot be fitted to a Phase 4 Motor Control Module. The colour of the module is a good indicator.
  • Page 44 132. (10000100) Phase 1 to 4 - Single Current Trip The Motor Control Module has detected excess current in the motor or electronic switches. This fault has occurred momentarily. Primary Source: Wiring. Action: Check the wiring connections from the Motor Control Module to the Stator and the Rotor Position Sensor.
  • Page 45 136. (10001000) Phase 1 to 6 - Motor Stall The Motor Control Module has been unable to start the motor. Possible causes of this fault are: Faulty motor harness, faulty or jammed motor, seized bearings or seals, faulty Motor Control Module, faulty Rotor Position Sensor or harness.
  • Page 46 Secondary Source: Motor Control Module. (Phase 1 to 4 only.) Action: If the SmartDrive is empty of water at fault it is possible that the pump circuit is faulty and has caused a pump out during wash. This would cause the bowl to re-engage during agitate and the Motor Control Module to display this fault.
  • Page 47 163. (10100011) Phase 4 to 6 - Valve Reset Pin Connect Fault The Motor Control Module has sensed the PCB connection is open circuit. The cold valve cannot operate with this condition. Primary Source: Motor Control Module. Action: Replace Motor Control Module. 164.
  • Page 48 231. (11100111) Phase 6 - MW GW Link Error Component has failed on the display board. Primary Fault: Display Module fault. Action: Replace Display Module. 232.
