Fault Codes
1.
Motor Control Module Fault
The Motor Control Module has encountered an error when writing to an EEPROM address.
Primary Source:
Motor Control Module.
Action:
Replace Motor Control Module.
9.
Size Error
The Motor Control Module has found a fault with the size setting.
Primary Source:
Motor Control Module.
Action:
Replace Motor Control Module.
10.
Temperature Sensor (Thermistor) Error
The temperature sensor may be open circuit.
Primary Source:
Thermistor
Secondary Source:
Motor Control Module
Action:
1. Check the connection of the thermistor to the Motor Control
Module.
2. Check resistance of temperature sensor. Resistance should be
10k
Ω
@ 25
o
C or 12.5k
Ω
@ 20
o
C. Replace if faulty.
3. Replace Motor Control Module.
12.
Flood Protection Error
The Motor Control Module has detected the water level to be above the flood level and tried
to pump the excess water out. After pumping for 30 seconds, the pump has been unable to
lower the water level below the flood level. The water valves may have stuck on and are
letting water in at a flow rate that is higher than the pump can handle, or the pump may be
blocked and cannot drain the excess water. Note: Under extremely high flow rate conditions
the machine may overfill during the “top-up” routine in agitate.
Primary Source:
Water Valves.
Action:
If the water valves are on continuously, check that the water valves
turn off mechanically, by removing power to the machine.
Secondary Source:
Pump system.
Action:
Check the pump for blockages and drain hose for correct height and
kinking
Tertiary Source:
Motor Control Module.
Action:
If water valves are being driven on electrically, replace Motor Control
Module.
21
Water Valve Over Current
The Motor Control Module has detected that the water valve circuit is drawing to high a
current.
Primary Source:
Water valves.
Action:
Check that the resistance of the water valves are 61-64
Ω
@ 20
o
C.
Secondary Source:
Motor Control Module
Action:
Replace the Motor Control module.
26.
Detergent Valve Fault
The Motor Controller module has detected that the detergent valve (purple clip) is faulty. It determines
this by measuring voltages from the valve diagnostic circuit. The most likely cause is that the valve
harness has not been connected correctly or the valve is open circuit.
