4. Servicing must be preceded by Earth Continuity, Earth Resistance and Insulation Resistance
checks.
5. Personal safety precautions must be taken to protect against accidents caused by sharp edges on
metal and plastic parts.
6. After servicing the appliance must be rechecked for Electrical Safety. In the case of appliances
which are connected to a water supply (i.e.: Washing Mach ines, Dishwashers & Foo d Centres etc.)
checks must be made for leaks from seals gaskets and pipe work and rectification carried out where
necessary.
7. It can be dangerous to attempt 'DIY' repairs / maintenance on complex equipment and the Company
recommends that any problem with the appliance is referred to its own Service Organisation.

FAULT FINDING
FAULT CODES
These models DO NOT display Fault Codes when the dryer develops a fault.
However an Auto Test feature is available to help diagnose faults.
Preliminary Checks:
Before performing any tests ALW AYS check that the W ater Cont ainer is empty and that the Condenser
Unit and the Drum Filter are NOT blocked with fluff or lint, as this may be the cause or partial cause of
the of the fault.
Auto Test
If a Fault is detected the dryer will not move on to the next phase of the test, but will perform the
following sequence:
> Beep Once
> Pause for 30 Seconds
> Beep 3 Times
> The End LED will display
This will Indicate the dryer has a Fault, but it will not indicate the exact cause of the problem.
Observing at which phase the auto test ends gives an indication of the type of fault and cause.
See the information on the following pages.

Auto Test Sequence
Before Starting the Auto Test, make sure the Water Container is empty, the Filter and
Condenser are Clear of fluff or lint.
Auto Test - Preparation:
If you are including the Conductivity Sensor Test when running the test procedure:
1. Attach the magnetic end of the 270 K ohm test lead to the metal strip conductivity sensor inside
the drum.
2. Connect the ring terminal end to an earth point on the cabinet of the machine. (The Ai r Duct fixing
screw is recommended).
3. After attaching, check Earth Continuity between this ring terminal and the mains power plug Earth
pin on or the metal rear panel of the dryer, using a multimeter.
The continuity resistance reading should be 1 ohm or less.

AUTO TEST - CONDENSER DRYERS
SAFETY WARNING !
When performing the Auto Test you will need to remove the top cover of the Dryer while
Electrical power is still applied.
To avoid the risk of electric shock, during this sequence you MUST make certain no
persons have any contact with the LIVE area around the Mains Terminal Block (cable entry
position) or main Power module behind the Console.
Preparation:
1. Remove the 2 screws securing the top cover to allow its removal when required during the test
sequence.
2. If necessary fit the Magnetic Test resistor. See page 7 for details.
To Enter Auto Test Mode - Condenser Models
1. The dryer must be plugged into the electricity supply with the Programme Selector set to the
“OFF” Position.
2. Turn the Selector Clockwise to Programme 1. Wait for the LED’s to turn OFF.
3. Push the Delay Option Button once.
4. Turn the Selector Clockwise to Programme 2.
5. Push the Delay Option Button once.
6. Turn the Selector Anti-Clockwise to Position 15.
7. Push the Start Button once.
This starts the test, indicated by the drum rotating clockwise fo r a short period - approximately
7 -8 seconds.
Note: If after starting the Auto Tes t and the drum has not Pause d within 15 seconds, the a uto test
has not been entered successfully, turn the control Knob to OFF, and repeat the above sequence.
TEST SEQUENCE - for a CONDENSER DRYER which has no detectable Faults
1. The Drum Rotates Clockwise for about 7 or 8 seconds.
Pause.
At this point remove the top cover. Remove the Water Bottle and pour 300 ml of water into the
Water Bottle support. (This will operate the Float Switch at the base of the dryer).
2. Refit the Water Bottle (if the Water Bottle is not replaced the test will fail at this point).
3. The dryer will pause until the Float Switch has moved to the full position.
The drain pump will turn on and the drum will rotate Clockwise for about 15 seconds.
The water that was poured into the support (filling the pump) will be pumped into the water bottle.
Pause for 5 seconds.
4. The Drum Rotates Anti-Clockwise with the Heater On (both elements) until the Rear Thermistor
detects a temperature Rise, - the heater then turns OFF and the drum continues to rotate.
Pause for 5 seconds.
5. The Drum Rotates Clockwise with the Heater On until the Front Thermistor detects a temperature
change, the Heater turns Off and the drum continues to rotate.
Long Pause.
6. 3 Beeps then the END LED Illuminates.
7. Test Ends.

TEST SEQUENCE - for a CONDENSER DRYER which has a Fault,
1. The Drum rotates clockwise for about 7 to 8 seconds
Step Phase: Float switch operation and Drain Pump operation
At this point remove the top cover. Remove the Water Bottle and pour 300 ml of water into the
Water Bottle support. This will operate the Float Switch at the base of the dryer.
2. Refit the Water Bottle (if the Water Bottle is not replaced the test will fail at this point).
3. The dryer will pause until the Float Switch has moved to the full position.
The drain pump will turn on and the dr um wi ll r otate Clockwi se for abou t 15 se conds - ac tual Ti me
depends on quantity of water in the base reservoir.
The water that was poured into the support (filling the pump) will be pumped into the water bottle.
Pause 5 seconds.
Step Phase: Heater Operation and Rear Thermistor Temperature Check
4. Drum Rotates Anti-Clockwise with the Heater On (both elements) until the Rear The r mistor
detects a temperature Rise, - the heater then turns OFF and the drum continues to rotate for a
short period.
Pause for 5 seconds.
Step Phase: Heater Operation and Front Thermistor Temperature Check
5. Drum turns Clockwise with Heater On (both elements), until the Front Thermistor detects a
temperature change.
6. Heater will Turn Off, the Drum will continue for a few minutes..
Step Phase: Conductivity Sensor Check (only applies if magnetic resistance is being used)
8. Test Ends
If the pump is faulty or a there is a blockage in the hose or a pump wiring fault, the
Water container will not fill with water at this point, and the drum wil l continue to turn
for approx. 3 minutes, then the dryer beeps, paus es fo r 30 se con ds , bee ps 3 times
then the Test Ends.
If the Rear Thermistor, Thermostat or Heater is Open Circuit (both Elements) or
disconnected the Test Cycle will finish at this point - then the dryer beeps, pauses
for 30 seconds, beeps 3 times then the Test Ends.
If the Front Thermistor, is Open Circuit or disconnected the Test Cycle will finish at
this point - then the dryer beeps, pauses for 30 seconds, beeps 3 times then the
Test Ends.

DRYER OPERATION CHECK - Condenser Models
When Checking Heater, Drum Action or Thermistor Operation, you are advised to use a Timed
Programme.
When Sensor Programmes are used, after the module has estimated the weight of the clothes and the
cycle time required to dry the clothes, the Dryer will start to reverse tumble.
Note: This weight and estimated drying time are calculated by the module which monitors the front
thermistor temperature increase in the Front Air Duct over a period of time.
For example, a small load will allow a faster temperature rise at the front thermistor.
A large load would cause the temperature to rise more slowly.
Drum
When set to a Timed Programme the machine will reverse for a short period approximately every 5
minutes.
Heater
Faulty or Disconnected Thermistors (Front and Rear) and the associated wiring will cause the
machine not to heat. (If an Auto Cycle is used the dryer may operate at ½ Heat, depending on cycle
used).
In these instances the machines will complete the Cycle without Heating with no indication to the user,
other than the load will be cold and wet at the end of the cycle.
One Element Open Circuit - Dryer works at 1.15 kW and dries normally taking slightly longer to
complete the cycle.
Thermistors
Rear Thermistor (Located on Heater Frame) next to the Cycling and One-Shot cut-outs.
