6 DIAGNOSTICS

6.1 Overview – LCD Models

If a fault occurs that prevents correct operation

of the dryer, and is detected by the controllers,

the dryer is stopped, the LCD shows a fault

code and the beeper is continuously turned on

and off.

Pressing any button once will disable the

beeping. The fault code information will remain

on the LCD screen until the power supply to the

dryer is turned off.

If the Dryer has been either turned off or isolated from the power supply, the fault code can be

recalled from memory by entering diagnostic mode. (Refer to Section

7.1).

If START/PAUSE is pressed while the fault code is displayed, the beeping will stop and the optical

download is activated. (Refer to Section

7.4).

User Warnings

In the case of User Warnings, the LCD screen will display the User Warning and the beep tone will

change from a continuous tone to a musical series of beeps, which are repeated every 5 seconds.

Depending on the nature of the User Warning, the operation of the dryer may cease or continue to

‘limp on’ until the cycle finishes or the user intervenes.

Pressing the POWER button when a User Warning is displayed will immediately turn the dryer off.

User Warnings are saved to memory as Fault Codes, and the last Fault Code will be permanently

stored.

The warning will also be recorded in the Warning Status screen (refer to Section

7.2.3), however the information on this screen will only be stored for as long as power is supplied to the dryer. When the dryer is isolated from the supply, the information in this screen will be erased.

6.2 Overview – LED Models

If a fault occurs that prevents correct operation of the dryer, and is detected by the controllers, the dryer is stopped, the LEDs flash showing a fault code and the beeper is continuously turned on and off.

Pressing any button once will disable the beeping. The fault code information will remain in memory.

If the Dryer has been either turned off or isolated from the power supply, the fault code can be recalled from memory by entering diagnostic mode. (Refer to Section

8.1).

If START/PAUSE is pressed while the fault code is displayed, the beeping will stop and the optical download is activated. (Refer to Section

8.4).

Page 12

517760C

User Warnings

There are two possible user warnings.

1. The machine is beeping and the lidlock light is flashing: Close the lid and press Start/Pause. If the lid is already closed, open and close it again, then press Start/Pause. Disconnect from the power (either by unplugging the dryer or turning off at the power supply). Wait 10 seconds. Reconnect and try turning the dryer on again.

2. The machine is beeping and the Time Dry 20 min is flashing: The machine is unable to close the drum due to clothes interfering with the closing mechanism. Remove any articles that are interfering with the drum door and dry these in the next load. Is the load higher than the lint bucket? Remove some articles and dry these in the next load.

circuits. Approximate resistances (+

10%) at various temperatures are; 32oF

= 33 kOhms, 72

F = 11 kOhms, 104oF = 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 Volt Supply Measurement Error.

The sensor module measures low voltage on actuator power supply. Remedy: Replace 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 Airflow Restriction – (User Warning).

Airflow restriction. Remedy: (1) Check that the lint bucket is empty and the filter is clear.

(2) Ensure that the exhaust duct is not restricted, blocked or kinked, preventing

good airflow. (3) Ensure that there is nothing inhibiting unrestricted airflow through the heater

housing, through the drum, lint filter, 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.

Page 14

517760C

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 floor.

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

refitted. (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 within +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 sufficient

power to the sensor module. When the 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

confirm the 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.

Page 15

517760C

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

On power up, the display has checked its memory against a known reference and found differences. Remedy: Replace the display module.

Fault Code 105 Comms Error Time Out

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 in this harness. (3) Replace the display module. (4) Replace the sensor module.

Fault Code 233 EEPROM Read Error (LCD models only)

The sensor module has problems reading the EEPROM data in the display module. Remedy: Replace the display module.

Notes:

1. If the dryer has stopped mid cycle with the Wrinkle Free LED illuminated, the LCD

screen (LCD models) or display LEDs (LED models) blank, and no fault "beeps", the dryer may be experiencing a low voltage supply. At such a level the dryer cannot function. Once the line voltage returns to normal, the dryer will recommence the interrupted cycle.

2. If the power supply has been turned off, the dryer may momentarily display the state

described in Note 1 prior to fully shutting down.

Note: Fault codes 7b, 45, and 105 will be reset if the power is switched off.

Press & Hold for 2 seconds

Page 17

517760C

7.2.2 Machine Status Screen

Machine Status Screen Tacho: This displays the

position of the drum. The displayed figure is updated every five seconds and will change as the drum revolves.

Exht tmp: This displays the temperature in oC of the exhaust sensor. Actuator: This displays the count of the current draw of the actuator motor.

Tacho Err: During reversals of the drum there will often be a transient error because of uncertainty

of direction during the reversing process, but this should be corrected on the next revolution.

Touch: This displays the impedance of the conductivity contacts (refer to Section

7.3).

LED Cnt: This is a measure of the infra-red light intensity required to sense the drum position. It

is normally about 14 but can range from 5 to 53.

7.2.3 Warning Status Screen

The last User Warning will be displayed on this screen and will be displayed until another User Warning overwrites it or the power is switched off.

7.3 Testing the Conductivity Contacts

Impedance Testing

It is possible to check the integrity of the conductivity contacts through diagnostics. Firstly enter the Machine Status Screen as described in Section

7.2.2, and when in this mode, by touching damp clothes or fingers across the conductivity contacts, the value adjacent to the word Touch will increase. The minimum value is zero. This indicates an open circuit. The maximum value is 255. No change in this value when touching the contacts, or conversely a high value when not touching the contacts, would indicate a fault in this circuit.

Resistance Test

An alternative, but slightly less reliable, method of testing the conductivity contacts is to test the circuit with a multimeter. When using this method, the power to the dryer must be switched off. Place one probe of the multimeter on each conductivity contact. The resistance should be

6.4Mohms +

2%.

7.4 Data Download Mode

Encoded data is transmitted out of the white Wrinkle Free LED, and can be captured by an optical download pen attached to a PC or hand held palm PC, where “Smart Tool” software interprets the data to aid servicing.

1. Enter diagnostic mode as described in Section

7.1.

2. Push the START/PAUSE button and the Wrinkle Free LED will flash. The machine is now in data download mode.

To exit from the data download mode, press the POWER button.

Page 18

517760C

7.5 Showroom Mode

Showroom mode will play the introduction and repeat it continuously, until the dryer has been isolated from the power supply.

To access the showroom mode follow the steps below.

1. Turn the power supply to the dryer on.

2. During the introduction sequence on the LCD display (which lasts for approx. 1 minute) press and hold the START/PAUSE button, then press the SELECT butt on and hold these buttons for at least two seconds.

To exit, turn off the power supply to the dryer at the wall.

8 DIAGNOSTIC MODE – LED MODELS

8.1 Entering the Diagnostic Mode

To enter the Diagnostic Mode, turn the power on at the power point and off at the console.

1. Press and hold the WRINKLE FREE button, then press the POWER button until the machine beeps and all eight LEDs across the top of the machine illuminate. The dryer is now in Diagnostic Mode.

2. Press the TIME DRY button three times to read the last fault.

The fault code is displayed in the row of eight cycle LEDs using a binary code. Each LED has a value as follows:

LED VALUE

Regular = 128 Heavy = 64 Delicate = 32 Sheets = 16 Air Dry = 8 Bulky = 4 Easy Iron = 2

Wrinkle Free = 1 The fault code is determined by adding up the value of the illuminated LEDs. For Example:

128 64 32 16 8 4 2 1 In this example, the LEDs with value “8” “2” and “1” are on.

Therefore 8+2+1=11. Fault code 11 is displayed. Investigate corrective action in sequence as listed in the fault code summary in Section

6.3.

To exit the diagnostic mode, press the POWER button.

Press and Hold START/PAUSE, then press the SELECT button

Page 19

517760C

8.2 Testing the Conductivity Contacts

Impedance Test

To enter the conductivity impedance test mode, enter the diagnostic mode then press the TIME

DRY button five times. In this mode, touching damp clothes or fingers across the conductivity

contacts will cause the LED display to change. If the contacts, or harness to them, have gone

open circuit, no change will occur in the LED display. This is a useful method of checking the

integrity of the sensor cells. To exit the diagnostic mode, press the POWER button.

Resistance Test

An alternative, but slightly less reliable, method of testing the conductivity contacts is to test the

circuit with a multimeter. When using this method, the power to the dryer must be switched off.

Place one probe of the multimeter on each conductivity contact. The resistance should be

6.4Mohms +

2%.

8.3 Show Room Mode

To enter Show room mode, ensure the dryer is on at the power supply but off at the console. Push

and hold the DRYNESS LEVEL button, then press the POWER button.

To exit show room mode, disconnect the machine from the power supply.

8.4 Data Download Mode

Encoded data is transmitted out of the Lid Lock LED, and can be captured by an optical download

pen attached to a PC or hand held palm PC, where “Smart Tool” software interprets the data to aid

servicing. To enter the data down load mode.

1. Enter diagnostic mode as described in Section

8.1.

2. Push the START/PAUSE button and the Lid Lock LED will flash. The machine is now in down load mode

To exit the Data Download mode, press the POWER button.

9 AUTOSENSING

When wet or damp clothes are loaded into a dryer they are partially saturated with water, which is a relatively good conductor of electricity. In the AeroSmart™ dryer, sensor bars (located beneath the lint bucket) are used to measure the conductivity. When moisture in the clothes touches across the sensor bars, their conductivity is measured. As the clothes dry they become less conductive and it is this measurement that is used to calculate the dryness of the clothes load. Large loads will brush against these sensor bars more frequently than small loads, and this strike count is used to help determine the dryness of different sized loads.

Different fabrics retain moisture differently. A thick towel containing a lot of moisture will often conduct the same as a light synthetic garment containing very little. It is this difference in fabric characteristics plus the initial unknown moisture content that makes the calculation of dryness reasonably complex. To test the sensor bars, refer to Section

7.3 (LCD models) or Section 8.2

(LED models).

10 TEMPERATURE CONTROL

Autosensing is automatically selected when the AeroSmart™ dryer is turned on. The user can select a time dry option of 20, 40 or 80 minutes through the Options menu. Autosensing of the clothes load dryness level is achieved by touch sensors that sense the moisture content of the load. An exhaust temperature sensor is used to monitor the exhaust temperature. The controller limits the temperature to what is required for the various cycles and determines what elements are used.

11 COOL DOWN

The dryer enters a cool down period at the end of the cycle. During this period the dryer continues to run with the heating elements/burner turned off, blowing ambient air through the load to help prevent creasing.

Autosensing: If any AutoSensing cycle has been selected, the cool down period will continue until the exhaust temperature drops to 95

F (35oC). However, if this temperature is not achieved after

10 minutes, the cycle will stop. This would occur if the ambient temperature was above 95

(35

C).

Timed Dry: If an 80 minute or 40 minute Timed Dry cycle has been selected, the cool down period will run for the last 10 minutes of that cycle. If a 20 minutes Timed Dry cycle has been selected, the cool down period will run for the last 5 minutes.

Cycle Cool Down
