The following are the fault codes that may
be displayed. The remedy section of each
fault is the suggested sequence of repair or
replacement. If the fi rst suggestion does not
remedy the fault, check the next on the list
Fault Code 1 Communications Error.
Communications failure between the sensor module and
motor control module.
Remedy:
(1)
Check the continuity of the module
interconnecting harness.
(2) Replace the sensor module.
(3) Replace the motor control module.
Fault Code 2 Drum Gap Cannot be Located.
Remedy: (1) Ensure the sensor module is correctly located
and clipped into place.
(2) Replace the lens on the sensor module.
(3) Replace the sensor module.
(4)
Remove the top deck and clean the drum
sensing“bumps” on the outside of the drum
end.
(5) Replace the drum.
Fault Code 3 Drum Stalled.
Remedy: (1) If there is mechanical movement of the drum,
but this fault code is appearing, follow the
procedures for fault code 2.
(2) If there is no mechanical movement of the drum,
check drum movement mechanisms: belt, motor
and motor harness.
(3) Replace the motor control module.
(4) Replace the motor.
Fault Code 4 Invalid Option Link Read.
The motor control module heat source option link read is
invalid.
Remedy: Repl ace the motor
Fault Code 6 Door Jammed – (User Warning).
The door is unable to close due to either clothes catching or
an excessive closing load.
Remedy: (1) Remove the obstruction.
(2) Reposition or remove some of the load.
(3) Fix the cause of binding in the door closing
mechanism.
(4) Replace the motor.
Fault Code 7 Motor Current Excessive.
Remedy: (1) Free up the dryer. Remove overload or cause of
jamming.
(2) Replace the motor control module.
(3) Replace the motor.
Fault Code 7 Display Module RAM Check Error – I only
On power up, the display has checked its memory against a
known reference and found differences.
Remedy: Replace the display module.
Fault Code 8 Exhaust Sensor Over Temperature.
The exhaust sensor measures over temperature (element
short circuit or low resistance).
Remedy: (1) Check the integrity of the sensor circuit checking
particularly for short circuits.Approximate
resistances (
+
/
–
10%) at various temperatures
are; 0°C = 33 kOhms, 22°C = 11 kOhms, 40°C
= 5 kOhms. Replace thermistor and harness if
out of range.
(2) Check the element integrity in that it switches off
when the dryer is stopped.
(3) Replace the motor control module.
(4) Replace the sensor module.
Fault Code 9 Exhaust Sensor Under Temperature.
The exhaust sensor measures under temperature (open
circuit or not plugged in).
Remedy: Refer to steps for over temperature fault (fault code
8) above, but open circuit likely.
Fault Code 10 24 Vo lt Supply Measurement Error.
The sensor module measures low voltage on actuator power
supply.
Remedy: Repl ace the sensor module.
Fault Code 11 Lid Lock Open Circuit.
Remedy:
Check the lid lock harness and coil. If there
is continuity through these, replace the sensor
module.
Fault Code 12 Lid Lock Switching Device Failure.
Remedy: Check that there are no short circuits in the lid
lock circuit which may have caused the failure in
the sensor module. The resistance of the lid lock
should be between 50 and 100 ohms. If the circuit is
correct, replace the sensor module.
Fault Code 14 Sensor Module Fault.
Remedy: Replace the sensor module.
Fault Code 15 Sensor Module Fault.
Remedy: Replace the sensor module.
Fault Code 16 Airfl ow Restriction – (User Warning).
Airfl ow restriction.
Remedy: (1) Check that the lint bucket is empty and the fi lter is
clear.
(2) Ensure that the exhaust duct is not restricted,
blocked or kinked, preventing good airfl ow.
(3)
Ensure that there is nothing inhibiting
unrestricted airfl ow through the heater housing,
through the drum, lint fi lter, lint collector and
through the exhaust duct, and that the element
has not shorted. If the dryer is located in a
closet ensure there is adequate ventilation for
air intake.
(4) Check that the voltage is not too high.
(5) Check for element shorts or low resistance.
(6) Replace the automatic thermostat.
(7) Replace the motor control module.
Fault Code 20 Door Actuator Stalled.
Remedy: As per fault code 21.
Fault Code 21 Door Actuator Required Excess Voltage.
Remedy: (1) Ensure there is no weight placed on the lid of the
product (e.g. clothes basket). If so, remove the
weight and retest.
(2)
Inspect the installation, making sure that the
cabinet sits evenly on the fl oor. If excess load is
placed on the cabinet, it can cause the sub-deck
assembly to twist.
(3) Inspect the front inside edge of the top deck
for any signs of excessive inwards bowing as
this can cause it to catch on the door grabber,
resulting in excess current draw on activation.
The bowing can be caused by a bowed top deck
or by incorrect assembly of the top deck to the
cabinet front.
(4) Ensure the user intervention tab is not inhibiting
door grabber movement.
(5)
Check that the actuator linkage is located
correctly. There must be no gap between the
linkage and the plastic moulding.
(6) Check that the actuator housing is in place, and
that the four retaining lugs are correctly located.
Early models may have aluminium tape holding
the housing in place. If so, ensure that the tape
is replaced when the housing is refi tted.
(7)
Remove the actuator housing and look for
obvious signs of things that are out of position
(can the worm drive be rotated freely both
backwards and forwards by hand, is the actuator
motor in place?)
(8) Replace the faulty door actuator mechanism.
(9)
Replace the door grabber, linkage and
housings.
(10) Replace the sensor module.
Fault Code 22 Door Actuator Open Circuit.
Remedy: (1) Check that the actuator wiring is plugged into the
sensor module and is not open circuit. If faulty,
replace.
(2) Replace the sensor module.
Fault Code 23 Door Actuator Movement Interrupted By
Low Voltage.
The door actuator movement was interrupted by low voltage
(brown out).
Remedy: (1) Ensure mains voltage is 10% and –15%
of nominal.
(2)
Replace the sensor module, as voltage
measurement circuit may be reading incorrectly.
(3)
Replace the motor control module, as it may
not be supplying suffi cient power to the sensor
module. When display is off, approximately 24V
DC is supplied.
Fault Code 24 Door Actuator Movement Took Too Long.
Remedy: As per fault code 21.
Fault Code 28 Data Retrieval Error Following Loss of
Power
Remedy: (1) Switch off the mains power supply to the dryer
for at least 10 seconds and confi rm error.
(2) Replace the motor control module.
Fault Code 29 Brown-Out Data Retrieval Error.
Remedy: (1) If the fault occurs every time the dryer is turned
on, replace the sensor module.
(2) Replace the motor control module.
Fault Code 30 Lid Lock unable to Lock – (User Warning).
Reason: The lid lock failed to lock. (Not user displayed.)
Remedy:
(1) Ensure the lid is closed and the tongue
engaged.
(2) Replace the lid lock harness.
(3) Replace the lid lock.
(4) Replace the sensor module.
Fault Code 45 Display Module ROM Check Error – I only
On power up, the display has checked its memory against a
known reference and found differences.
Remedy: Replace display module.
Fault Code 105 Comms Error Time Out – I only
Communications failure between the sensor module and
display module.
Remedy: (1) Visually check the contacts on the RAST (edge)
connector at each end on the harness between
the sensor module and display module.
(2) Using a multimeter check for continuity of the
wires on this harness.
(3) Replace display module.
(4) Replace sensor module.
Note:
The blue or green Air Dry LED illuminated without the
fault “beeps” indicates the dryer is in a low mains voltage
(brown out) state, and may be momentarily displayed when
the supply power is turned off.
