2 PRINCIPLES OF OPERATION
2.1 Vented Dryer
The ambient air is drawn into the cabinet by the fan
which is attached to the motor. This air pressurises
the cabinet and is forced over the heating element
and heated. The heated air then enters from the rear
of the drum and meets with the clothes, with the
humid hot air exiting through the lint filter and exhaust
duct.
3 COMPONENTS
3.1 Mechanical Parts (Dynamic System)
The main motor is attached to the motor brackets by 2 spring clips. In order to drive the drum, a
poly-v belt is used between the motor pulley and drum. The drum is made of pre-painted or
stainless sheet steel. The drum group is mounted into the front bearing housing and the rear
bearing is fixed to the inside rear of the drum by 4 screws and mounted to the heater plate. The
heater is mounted to the rear plate which is held in place by 2 brackets which are mounted to the
wrapper.
3.2 Temperature Sensors & Thermostat
3.2.1 Thermostats
There are 2 thermostats used, with both being located and mounted to the heater plate. These
measure heater temperatures, and thereby control the heater’s ON/OFF periods.
These will trip open when they reach 73°C +/- 3°C and will close when they get to 58°C +/- 5°C
3.2.2 Exhaust Sensor ED50F56EW
This is located in the exhaust and sensors the exhaust temperature.
3.3 Heater
A 1750-watt, 2-circuit or 1 circuit, tubular stainless steel element is used which is driven by the
timer for the analogue and by 2 relays in the electronic dryers, with the elements being energized
after the motor has started to run.

3.4 Door Lock
The locking and unlocking mechanism of the door used in the dryers is a mechanical type. When
the door is pushed closed, the strike is locked into the catch and holds the door shut.
3.5 Door Micro Switch
3.5.1 DE40F56AW & DE50F56AW
The main power via the active line is connected to the door switch and then to the timer control.
When the door is open, the contacts are opened, so the active supply is cut from the timer with the
motor and heater stopped.
3.5.2 DE50F56EW
The door switch is connected to the electronic control module which when closed allows the start
pause button to be activated starting the motor and heater element. When the door is opened the
switch becomes open and stops the controller from driving the motor or heater.
3.6 Electronic Module DE50F56EW
The electronic module controls the dryers main motor at a constant speed. It also manages the
program steps, reads the temperature of the NTC’s and activates or deactivates the heater.
3.7 Main Motor
The main motor is a single phase permanent split capacitor motor which runs at approximately
1400 rpm and is equipped with a 7uF run capacitor. The motor is controlled by relays in the
DE50F56EW and by the timer in the DE50F56AW which reverse the directions of the drum. The
DE40F56AW has only one direction and does not reverse.

7 ELECTRONIC MODULE CONNECTION CHECK
The following is a quick test procedure to check that the electronic module is correctly wired to the
dryer and that the dryer is operating correctly
7.1 Led & Button Test
1. Press and hold the LOCK, button, and then press the DRYNESS up button so that
both buttons are pressed down at the same time.
All LEDs should be on:
2. Press the POWER button to turn the LEDs off.
3. Press the POWER button and check all the other buttons are working. Check that the
buzzer is sounding.
7.2 Drum Rotation & Element Check
1. Connect an amp meter or watt meter in the mains supply to the dryer.
Turn the dryer on and set the temperature to Regular, then press the START/PAUSE
button to start.
Amp meter should read approx 8.5 amps OR watt meter should read 2000 watts.
Note 1: If the dryer does not start, check the door switch adjustment (for other faults refer to
the FAULT CODES section).
Note 2: A failure on the control module will cause a fault code to be displayed on the
Dryness LEDs. This happens approximately 12 seconds after the initial pressing of the
START/PAUSE button and overwrites the operational display (refer to the FAULT
CODES section).
2. Press the START/PAUSE button twice.
The dryer should stop and reverse direction.
Amp meter should again read approx 8.5 amps or the watt meter should read 2000 watts.
3. Press the START/PAUSE button and use the TEMPERATURE down button to set
the temperature to airing.
4. Press the START/PAUSE button the Amp meter should read approximately 0.5 amps or
the watt meter 130 watts.

7.3 Exhaust Sensor & Door Switch Test
1. Start the dryer running in Low or Regular Temperature mode; then press and hold the LOCK
button, and then press the START/PAUSE button.
Note: This advances the drying cycle so that a shorted temperature sensor can be detected.
(Refer to Faulty Exhaust Sensor section).
2. Press and hold the LOCK button; then press the DRYNESS button. Release these
buttons and press the START/PAUSE button.
If there is a fault with the exhaust sensor, the fault code will be immediately displayed, with
the beeper sounding (Refer to FAULT CODES section).
3. Open the door and the machine should pause. The three delay LEDs will turn on with the
door opened.

8 FAULT MODES
Should a fault develop in the Electronic Control system of the dryer, the control panel will display a
particular pattern on the Dryness LEDs as well as a continuous sounding of the buzzer.
If this occurs, first turn the dryer off at the mains socket or unplug the dryer, then reconnect to the
mains and retry the dryer.
8.1 FAULT CODES
If a fault should develop in the temperature measurement system of the dryer control system, a
fault code will be displayed on the front panel.
Fault codes are distinguished from the normal display in that only a combination of the 4 dryness
LEDs will be on and with the beeper sounding on and off.
If a fault code should appear, first switch the dryer off at the wall socket or remove the plug. Switch
on again. If the fault re-occurs, use the following codes to diagnose the fault.
The faults and their respective fault codes are as follows:
8.2 Faulty Exhaust Sensor
Code: 0101
OR 1001
Action: Unplug the exhaust sensor harness at the control module and check the resistance of the
sensor (refer to Testing the Exhaust Sensor section). If faulty replace it.
NOTE: A shorted exhaust sensor can also be sensed by the Temperature Measurement System
as a very low temperature reading. Remember the sensor decreases in resistance as the
temperature decreases. To stop a fault code showing at very low temperatures (below 0o), this
fault code will not show until 5 minutes after the dryer has started. This allows the sensors time to
be heated up by the exhaust air.
Refer EXHAUST SENSOR AND DOOR SWITCH TEST to eliminate this delay.

8.3 Exhaust Sensor Shorted to Cabinet
Code: 1010
Action: Unplug the exhaust sensor harness at the control module and check for continuity
between each of the sensor wires and the dryer cabinet. There should be no connection between
the wires and the cabinet.
If there is a short, replace the exhaust sensor and harness
8.4 Faulty Exhaust or Ambient Sensor
Code: 0110
Cause: The sensors are either open circuit or shorted.
Action: Unplug the exhaust sensor harness at the control module and check the resistance of the
sensor. (Refer to Testing the Exhaust Sensor). If faulty, replace it. If the ambient sensor is
faulty, the electronic module will have to be replaced.
8.5 Over Temperature
Code: 1101
Cause: If the exhaust air temperature is above 90oC a fault code is given as the dryer
should not reach this temperature under normal operating conditions.
Action: Check the lint filter and exhaust duct for any blockage or restriction to the airflow.
