- When Smartdrive detects a fault it stops. Smartdrive beeps continuously, once per second, and displays a fault code in binary using the 8 wash progress LEDs. The possible fault codes are listed in numeric order with their associated service procedure. The fault code binary value as represented by the Wash progress light condition is shown in brackets, e.g. Fault code 9 (00001001) “Size setting Error”. The rightmost binary character corresponds to the SPIN LED on the wash progress LEDs.

Primary
Source - Motor Controller (Display Module for Phase 1).
Action
- Replace Motor Controller (Display Module for Phase 1)
{00000011} Phase 1 to 5 - Motor Controller Fault.
The
Motor Controller has found a RAM error during it's initialization procedures.
Primary
Source - Motor Controller
Action
- Turn off at the wall and on again after 5 seconds and try again. If still
faulty then replace Motor Controller.
{00000100}
Phase 1 - Communications Fault.
The
Motor Controller has had difficulty communicating with the Display Module.
Primary
Source - Motor Controller
Action
–
Turn
off at the wall and on again after 5 seconds and try again.
If
still faulty, Replace Motor Controller
Replace
Display Module. If the new Display Module corrects the fault, then re-fit the original
Motor Controller.
{00000101} Phase 1 – Communications Fault
The Display Module has had difficulty communicating with the
Motor Controller.
Primary
Source - Display Module
Action:
Turn
off at the wall and on again after 5 seconds and try again. If still faulty, then:
Check
connections of the 12 way harness for bad contacts , corrosion etc
Check
for moisture in the console area. Dry out if necessary
If
still faulty, then replace Display Module
If still faulty, then replace Motor Controller. If the
new Motor Controller corrects the fault then re-fit the original Motor
Controller.
{00000110}
Phase 1 - Display Module Fault. Phase 2
to 4 Motor Controller Fault.
The
Motor Controller (Display Module for Phase 1) has received an incorrect signal
from the pressure sensor.
Primary
Source - Motor Controller (Display Module for Phase 1)
Action
- Replace Motor Controller (Display Module for Phase 1).
{00000111} Phase 1 to 5 - Display Module Fault.
The
Display micro has found a RAM error while testing RAM.
Primary
Source - Display Module
Action
- Replace Display Module.
{00001000} Phase 1 - Display Module Fault.
The
Display micro has not been able to start-up correctly.
Primary
Source - Display Module
Action
- Turn off at the wall and on again after 5 seconds and try again. If still
faulty replace Display Module.
{00001001} Phase
1 to 5 - Size Error.
Phase
1 to 3
Primary
Source - Display Module.
Action
- The Display Module has not been correctly located in the console. This
will not activate the size switches. Or the size switch may have been affected
by condensation.
- If the Display module has just been inserted into a console housing check that the two size switch plungers accurately locate onto the console housing. If this fault has appeared during normal operation of Smartdrive check the size switch or replace the Display module.
- If the Motor Controller has been changed from one size machine, to another then the size switch settings in the memory will have to be reset. Entering and exiting the Option Adjustment mode can do this. Push and hold START/PAUSE then push POWER button to enter Option Adjustment Mode. This sets the size into EEPROM
Phase
4 to 5.
The
Display size switch setting does not match that stored in memory.
- Action - Reselect the size of Smartdrive by using the SIZE SETTING MODE. Push and hold the water temp up button, then press the power button to enter SIZE SETTING MODE. Three LEDs are used to identify size. The cold water temperature LED identifies 5kg. The low water level LED identifies 6kg. The hold spin speed LED identifies 7kg. If the product has not been setup before all 3 LEDs will be on. To set the size for 5kg push the wash temp up button then the power button. To set the size for 6kg push the water level up button then the power button. To set the size for 7kg push the spin speed up button then the power button. This locks the size into memory. To check the size is set, start a cycle.
{ 00001010} Phase 1 to 5 - Thermistor Error.
The
resistance of the Thermistor is outside the normal limits, the fault is
probably due to an open circuit.
Primary
Source - Thermistor (Phase 5), Motor Controller (Phase 1 to 4)
Action: Phase
1
Check
connections of the 12 way harness
Check
for moisture in the console area
Replace
Display Module
Replace
Motor Controller. If new Motor Controller corrects fault then re-fit original
Display Module.
Phase 2 to 4:
Change Motor Controller.
Phase
5
Check
the connection of the thermistor to the Motor Controller.
Check
resistance of temperature sensor. The resistance of a good temperature sensor
is 12.5k ohms at 20C. Replace if faulty.
Replace
Motor Controller.
{ 00001011} Phase
1 to 5 - Pressure Sensor Fault.
While
measuring the water level the Motor Controller has detected a negative
pressure. Reconnecting the pressure
tube to the pressure sensor while the bowl contains water can cause this.
Primary
Source – Pressure Tube.
Action
- Check bowl is fully pumped out. Remove pressure tube from pressure
sensor, clear pressure tube of any water and reconnect tube.
Secondary
Source - Motor Controller. (Display Module Phase 1).
Action
- Replace the Motor Controller. (Display Module Phase 1).
{ 00001100} Phase 1 to 5 - Flood Protection Error.
The
Motor Controller has found the water level to be above the flood level and
tried to pump the excess water out. Either the water valves are 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 Smartdrive ).
Secondary
Source - Pump System
Action
- Check pump for blockage and hose for correct height and kinking.
Tertiary
Source - Motor Controller. (Display Module Phase 1).
Action
- If water valves are being driven on electrically, replace Motor
Controller. (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
The
pump is fitted with a thermal cut out device. Check if this device has been
activated. If it has wait until pump cools down before restarting. Check for
any pump blockage and check condition of pump i.e. pump seizure.
Check
for open circuit pump windings. Check the resistance of the pump.
Check
the pump harness or the connectors for an open circuit.
Replace
Display Module.
{00001110} Phase
1 - Pump Connection Fault.
The Display Module has detected that the pump is not on when
it should be.
Primary Source – Pump.
Action
The
pump is fitted with a thermal cut out device. Check if this device has been
activated. If the device is activated wait until pump cools down before
restarting. Check for any pump blockage and check condition of pump (pump
seizure).
Check
for open circuit pump windings. Check the resistance of the pump.
Check
the pump harness or the connectors for an open circuit.
Replace Display Module.
{00001111} Phase
1 - Display Module Fault.
The Display Module has read an incorrect voltage on the pump
circuit.
Primary
Source - Display Module
Action
- Replace Display Module. NB. If Smartdrive is running at well below
it's rated supply voltage and the pump has operated for more than 4 seconds at
this voltage this fault will also appear.

Sequence.
The
Display Module and Motor Controller are running out of sequence.
