(00001010) Phase 1 to 6 Temperature Sensor (Thermistor) Error The temperature sensor may be open circuit or the ambient temperature is below minus 10oC. This fault is only applicable in the Intuitive Washer and the GW models. Primary Source: Thermistor, Secondary Source Motor Controller Action: 1. Check the connection of the thermistor to the Motor Controller. 2. Check resistance of temperature sensor. Resistance should be 10k ohms @ 25oC or 12.5k ohms @ 20oC. Replace if faulty. 3. Replace motor controller. (00001011) Phase 1 to 6 - Pressure Sensor Fault While measuring the water level, the Motor Controller micro has detected a negative pressure. Reconnecting the pressure tube to the pressure sensor while the bowl has been partly filled with water may have caused this. Primary Source: Pressure Tube. Action: 1) Check bowl is fully pumped out. Remove pressure tube from pressure sensor, clear pressure tube of any water and reconnect tube. 2) If fault is still present, replace the Motor Controller module.(Display Module Phase 1) (00001100) Phase 1 to 6 - Flood Protection Error The Motor Controller 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 machine 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. Either the water valves have stuck on and are letting water in at a flow rate that is higher than the pump can handle, or the pump is blocked and can't remove the excess water. Primary Source: Water Valves. Action: If the water valves are on continuously, check that the water valves turn off mechanically (remove power from machine). Secondary Source: .Pump system Action: Check pump for blockage and drain hose for correct height and kinking Tertiary Source: Motor Controller module. (Display Module Phase 1) Action: If water valves are being driven on electrically, replace Motor Controller module. (Display Module Phase 1) (00001101) Phase 1 Pump Fault The Display module has detected that the pump is on when it should be off. Action: 1. The pump is fitted with a thermal cut out device. Check if this device has been activated. If it has wait until the pump cools down before restarting. Check for any pump blockage and condition of pump before attempting to restart. i.e. pump seizure. 2. Check for open circuit pump windings. Check the resistance of the pump. 3. Check the pump harness or the connectors for an open circuit. - 28 -

(00100001) Phase 1 Water Valve Fault The Module has detected a water valve fault. Primary Source: Water Valve connection Action: Check that both valves are connected up properly. Secondary Source: Water Valve coil faulty Action: 1. Check the valve coils are not open circuit. 2. Replace Display Module if the valve coils are not faulty. (00100010) Phase 1 Brake Resistor Fault The circuit that controls the braking of the motor is faulty. Primary Source: Motor Controller Action: Replace Motor Controller Secondary Source: Display Module Action: Replace the Display Module If the Display Module corrects the fault, then refit the original Motor Controller. (00100011) Phase 1 MC Reset Error The Display Module has sent a false signal to the Motor Controller. Primary Source: 12 way Harness Connection. Action: Check the 12 way harness connection between the display Module and the Motor Controller. Secondary Source: Display Module Action: Replace the Display Module. (00100100) Phase 1 to 6 - Water Leak Fault The Motor Controller module has needed to top up the water level more than 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 machine is siphoning. The other alternative is that the machine has developed a leak. Primary Source: Pump System. Action 1) Check the height of the drain hose outlet. Minimum 850mm, maximum 1200mm. 2) Check that the hose guide is fitted and check that the hose does not protrude more than 20mm beyond the guide. Secondary Source: Mechanical. Action: 1) Check the pressure tube connections on the outer bowl and Motor Controller module. 2) Check that the drive shaft seal and the pump housing seal have not developed a leak. Tertiary Source: Motor Controller module.(Display Module Phase1) Action: Replace Motor Controller module.(Display Module Phase 1)

(00100101) Phase 1 to 6 - Pump Blocked Error ( No change in the water While draining, the water level reading from the pressure sensor has not changed for over 3 minutes. There are three likely reasons for this fault. One is that the drain hose or the pressure switch hose has been squashed or kinked and the pump out rate has been dramatically reduced. The second possibility is that the pump is partially or fully blocked. The third is that the pump is not operating due to Motor Controller module, wiring or pump failure. This fault could also appear if the machine 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, water level is not altering as the diverter is stuck in the recirculation mode, giving the module the appearance the pump is not lowering the water level. Primary Source: Pump System. Action: 1) Check that the drain hose has not been kinked. 2) Check the length of the drain hose and try to reduce the length if excessively long. A 1 metre extension hose of the same diameter fitted to the existing drain hose is the maximum allowable length. 3) Check for open circuit windings in the pump. (Note: Pumps are fitted with a thermal cut-out which will reset on cooling.) 4) If the bowl is empty of water, remove the pump from the pump housing and check that it is not blocked. Also check the drain hose is not blocked. 5) If the bowl contains water, then service the pump from the top of the machine by removing the top deck and inner bowl. Bail out the water, remove the pump cap and hood and clear the restriction. Secondary Source: Wiring. Action: 1) Check the pump harness is connected correctly to the pump. 2) Check continuity of the pump harness. Tertiary Source: Motor Controller module. Action: Activate the pump by operating the machine in spin mode. Check the pump is rotating. If it is not operating, and Primary and Secondary checks have been performed, then replace the Motor Controller module. Note: Consider fitting Pump Hood Kit (WM013). If 5kg Smartdrive fit splash guard to pump. Quaternary Source: Diverter Valve failure (Phase 5 and 6 Eco's ) Action: Check the diverter valve, see fault code 51

(00100110) Phase 1 to 6 - Pressure Sensor Fault The Motor Controller module has recorded a water level of empty while it is agitating. The water level must have been greater than empty for the machine 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. Alternatively the pressure sensor may be faulty. Primary Source: Mechanical. Action: Check that the pressure tube is intact and has not been cut. Secondary Source: Motor Controller module. (Display Module Phase 1) - 31 -

Action: Replace the Motor Controller module if the pressure tube shows no sign of being faulty. ( Display Module Phase 1) 39. (00100111) Phase 1 to 6 - Pressure Tube Fault The probable cause of this fault is that the pressure tube has become blocked or kinked or has fallen off completely. Alternatively the pressure sensor may be faulty. Primary Source: Mechanical. Action: Check that the pressure tube is intact and not blocked with water or dirt and is not kinked. Secondary Source: Motor Controller module.(Display Module Phase 1) Action: Replace the Motor Controller module.(Display Module Phase 1) (00101000) Phase 1 to 6 - Bowl Dis-engage Fault While carrying out a bowl check, the Motor Controller module has found that the bowl is not engaged even though the pressure sensor indicates that the bowl is empty. The Motor Controller 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 Controller 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 Controller module.(Display Module Phase 1) Action: Replace Motor Controller module.(Display Module Phase 1) (00101001) Phase 1 to 6 - Temperature Sensor Fault (Thermistor) The temperature sensor is measuring temperatures above 110oC. The fault is probably due to a short circuit in the sensor line. (Only in the Intuitive Washer and the GW Models.) Primary Source: Thermistor (Phase 5 and 6) Motor Controller (Phase 1 to 4) Action: Phase 1 1. Check connections of the 12 way harness 2. Check for moisture in the console area 3. Replace Motor Controller. 4. Replace Display Module, if the new display fixes the fault then refit the original Motor Controller. Phase 2 to 4 Change Motor Controller module. Phase 5 and 6 Action: 1. Check the connection from the thermistor the Motor Controller 2. Check the resistance of the thermistor, should read 12.5k ohms at 20 degrees C. Replace if faulty. 3. Replace the Motor Controller module. - 32 -

(00101010) Phase 1 Rotor Fault Primary Source: The Motor Controller has had some confusing information feedback. Action: Turn off Smartdrive at the wall and back on again after 5 seconds. Restart. (00101011) Phase 1 to 6 - OOB Switch Fault The Motor Controller 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. Primary Source: Mechanical. Action: 1) Check that the out of balance switch is free to move. 2) Check that no harnesses are blocking switch movement. 3) Check that the switch operates correctly when activated. Replace the switch if suspect. 4) If the out of balance micro switch shows signs of corrosion, replace the switch and switch harness, and fit a condensation kit to the console area if not incorporated in the top deck. 5) Check the level of the machine and also the bias spring. Secondary Source: Wiring. Action: Check the harness to the switch is connected correctly. The terminals should be connected to the normally closed position. If the harness terminals show signs of corrosion, then fit a new harness. Tertiary Source: Motor Controller module.(Display Module Phase1 ) Action: Replace Motor Controller module.(Display Module Phase 1) (00101100) Phase 2 to 6 - Water in Bowl during Spin The Motor Controller has sensed a water level in the bowl during spin. This may be caused by a slow pump out rate due to a partial blockage in the pump hose or pump. Primary Source: Pump System. Action: 1) Check that the drain hose is not squashed or kinked. 2) Check the length of the drain hose and try to reduce the length if excessively long. A 1 metre extension hose of the same diameter fitted to the existing drain hose is the maximum allowable length. 3) If the bowl is empty of water, remove the pump from the pump housing and check that it is not blocked. Also check that the drain hose is not blocked. 4) If the bowl contains water, then service the pump from the top of the machine 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. 5) Check that water is not siphoning back into the machine when the pump turns off when the spin speed reaches 600 rpm Secondary Source: Motor Controller module. Action: Replace Motor Controller module.

(00101101) Phase 5 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. (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 (00101111) Phase 2 and 3 - Bowl Dis-engage Fault While carrying out a bowl check, the Motor Controller module has found that the bowl is not engaged even though the pressure sensor indicates that the bowl is empty. The Motor Controller 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 Controller module. Primary Source: Mechanical. Action: 1) Check that there are no clothes or other foreign objects preventing the clutch from re-engaging. 2) Next check that the pressure tube has not come off and that it is not kinked. Secondary Source:Motor Controller module. Action: Replace Motor Controller module, if the above checks out without fault.

(00110000) Phase 2 to 6 - Hot and Cold Valve Faulty The Motor Controller 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. Primary Source: Wiring. Action: Check the valve harnesses are correctly fastened to the valves or the pins are not bent backwards. Secondary Source: Water Valves. Action: Check the valve coils are not faulty (open circuit). Tertiary Source: Motor Controller module. Action: Replace the Motor Controller module. (00110001) Phase 2 to 6 - Cold Valve Faulty The Motor Controller 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.

(00110010) Phase 2 to 6 - Hot Valve Faulty The Motor Controller 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 smart drive powers off while spinning. There will actually be no fault if this has happened. (00110011) Phase 5 and 6 Eco - Diverter Valve Fault Primary: The motor controller 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. Action: Turn the power off at the machine 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 controller has failed due to the valve and both will need to be replaced. Secondary: Check for blockage in the valve itself or a broken hinge mechanism. (00110100) Phase 5 and 6 Eco - Diverter Top-up Fault 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 quick enough suggesting the valve has a blockage and is also draining. Primary Source: Diverter valve Action: Remove the diverter valve and check for blockages or broken hinge mechanism. Secondary Source: Wax Solenoid Action: Check the resistance of the wax solenoid, also look for corrosion on the terminals (greenie deposit) resistance range will be between 0.7k and 2.5k. Values are dependant on ambient temp and when the valve was last actuated. Anything outside of these values should be automatically replaced. (00110011) Phase 2 to 6 - Rotor Position Sensor Step Fail The motor controller has attempted a motor step test and has found that the motor has not stepped in the correct direction. It has detected that the motor is connected and that the motor drive is operational. The rotor position sensing system is at fault here. Primary Source: Wiring. Action: Check the Rotor Position Harness for continuity and that the connectors are correctly to the Rotor Position Sensor and the Motor Controller. Secondary Source: Rotor Position Sensor Action: Check the Rotor Position Sensor patterns with a RPS Tester, if faulty fit a new Rotor Position Sensor. Tertiary Source: Motor Controller module. Action: Replace the Motor Controller module as the sensing circuitry may be faulty.

(00110110) Phase 2 to 6 - Motor/Motor Controller module Step Fail The Motor Controller module has attempted a motor step test and has found that the motor has not stepped in the correct position. The Motor Controller module has detected that there is no current. This indicates that either the motor is not connected or the Motor Controller module motor drive is faulty. Primary Source: Wiring. Action: Check the continuity of the motor harness and that the connectors are correctly applied to the motor and Motor Controller module. Secondary Source: Motor. 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 Controller module. Action: Replace Motor Controller module. (00110111) Phase 3 to 6 System Step Fail Primary Source: Rotor Position Sensor Action: 1. Check Motor and Rotor Position Sensor wiring 2. Check Rotor Position Sensor with RPS Tester (00111000) Phase 4 to 6 - Bowl Check No Valid Fault While carrying out a bowl check, the machine has not been able to determine a valid bowl status and so the Display flags this fault. This fault differs from fault 40 in that a valid bowl status could not be determined. Phase 4 & 6 Primary 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. If the load was to one side of the bowl or too heavy it can be possible for the agitator to bind in one direction when trying to sense bowl float. Secondary Source: Mechanical. Action: 1. Check the machine is not syphoning. 2. Check that there are no clothes or other foreign objects preventing the clutch from re-engaging, and that there aren't any defects with the clutch mechanism. 3. Next check that the pressure tube has not come off and that it is not kinked. Tertiary Source: Rotor Position Sensor. Action: Replace the Rotor Position Sensor. Quaternary Source: Motor Control Module. Action: Replace the Motor Control Module.

(01101010) Phase 2 to 3 - Display to Motor Controller 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 Controller module. Primary Source: Display module. Action: Replace Display module. Secondary Source: Motor Controller module. Action: Replace Motor Controller module. If the new Motor Controller module corrects the fault, refit the original Display module. (01101011) Phase 2 to 6 - Motor Controller module Reset Error The Display Module has detected that the Motor Controller module has reset when it should not have. This can be due to a Motor Controller module supply disturbance or microprocessor failure. Primary source: Motor Controller module. Action: Replace Motor Controller module. (01101100) Coms CRC error Phase 6 IW Display only See fault code 106 (01111111) Phase 5 Machine Set up Error The display module has been fitted to the wrong model, size and or phase machine! eg. Phase 5 Display cannot be fitted to a Phase 4 Motor Controller! The colour of the modules is a good indicator, part numbers are also very important. (10000010) Phase 1 to 6 Single Rotor Position Sensor Error The Motor Controller has found an error in the pattern received from the Rotor Position Sensor. Likely causes of this fault are a bad connection on the harness between the Rotor Position Sensor and the Motor Controller, or a faulty Rotor Position Sensor. Primary Source: Wiring. Action: 1) Check for corrosion on the edge connector of the Rotor Position Sensor and the Motor Controller module connector. 2) Check the contacts on the rotor positional sensor end of the hall harness to see if any have been damaged. (Each set of contacts in the socket has two wipers. If the distance between these wipers varies between different contacts, replace the rotor positional sensor harness). Secondary Source: Rotor Position Sensor. Action: Check the Rotor Position Sensor with an R.P.S. tester. Replace if faulty. Tertiary Source: Motor Controller module. Action: Replace Motor Controller module.

(10000011) Phase 1 to 6 - Repetitive Rotor Position Sensor Error This fault is similar to fault number 130 above but differs slightly in that it is a continuous condition. See fault 130 for service procedure. (10000100) Phase 1 to 4 - Single Current Trip The Motor Controller 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 Controller to the Stator and the Rotor Position Sensor. Secondary Source: Motor. Action 1) Measure/check the motor harness, connectors and motor for shorts. This can be done by taking a resistance measurement between phases of the motor harness at the Motor Control module end. Nominal resistance should be around 12.2 ohm for Phase 2, 3 & Phase 4. For Phase 5 and 6 Smart Drive the nominal resistance should be around 32 ohms. 2) Check the Rotor Positional Sensor, Stator brass bridge terminal point and associated harness for water, mechanical damage or corrosion. Tertiary Source: Motor Controller module. Action If all the above show no signs of fault then replace the Motor Controller module. Also check for water leaks from the cooling chamber or valves that could possibly come in contact with the Motor Controller and fix the leak before replacing with new Motor Controller module. (10000101) Phase 1 to 4 - Repetitive Current Trip The Motor Controller has detected excess current in the motor or electronic switches. This fault is a more severe occurrence than Fault Number 132 but has identical fault sources and fault service procedure. (10000110) Phase 4 - Single Current Trip & Rotor Position Error The Motor Controller module has detected an excessive motor current AND a Rotor Position Sensor error simultaneously. See fault codes 130 and 132 for service procedure. (10001000) Phase 1 to 6 - Motor Stall The Motor Controller 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 Controller module, faulty Rotor Position Sensor or harness. Primary Source: Wiring. Action: Measure / check the motor harness, connectors and motor for discontinuity. This can be done by taking a resistance measurement between phases of the motor harness at the Motor Controller module end. Nominal resistance should be around 12.2 ohm for Phase 2,3 & Phase 4. For Phase 5 and 6 onwards the nominal resistance should be around 32 ohms. Secondary Source: Motor. Action: 1) Check free rotation of the agitator and bowl by rotating by hand. Bearings and seals may be seized. - 40 -

Action: If the primary and secondary checks pass inspection then replace the Motor Controller module. 144. (10010000) Phase 1 Motor Controller Software Trap The Motor Controller has developed a fault. Primary Source: Motor Controller Action: 1. Power off for 5 seconds and try again. 2. Check connections between the Display Module and the Motor Controller 3. Replace Motor Controller 160. (10100000) Phase 1 to 6 - Bowl Engaged The bowl has re-engaged itself during agitate. Possible causes for this are a leak in the air bell, the bowl is over-loaded with clothes, the clutch has jammed or is fouled with a foreign object. Primary Source: Mechanical. Action: 1) Check that the rotating bowl assembly is not jammed to the agitator with any foreign object that may be caught under the agitator skirt. 2) Check that the clutch teeth are not locked together with dirt, lint, etc. 3) Make sure the bowl is not overloaded with too many clothes. 4) If none of the above appear to be at fault, then check the air bell at the bottom of the inner bowl for leaks. Secondary Source: Motor Controller module. (Phase 1 to 4 only) Action: If the machine 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 Controller module to display this fault. Replace Motor Controller module. (10100001) Phase 2 to 6 - Hardware / EEPROM Supply Mismatch The Motor Controller checks the hardware configuration (ie. 110v or 230v ) against its EEPROM table on power up. Should there be a mismatch, this error is flagged. Primary Source: Motor Controller module. Action: Replace Motor Controller module. (10100010) Phase 3 to 5 - Brake Deceleration Time-out Fault During the brake mode, the Motor Controller has detected that the bowl has not come to a stop in the permitted time once dropping below 100rpm.
