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 ALWAYS check that the Water Container 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.

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.

DRYER OVERVIEW - CONDENSER MODELS
These Condenser Auto Tumble Dryers are freestanding with a round door on the front that can be
opened to allow the drum to be loaded with clothes.
The door is NOT reversible.
The facia moulding across the top of the front panel houses the dryer user controls and water
container.
Within the cabinet is a drum, which is capable of accepting a maximum 7 or 8 Kg* (depending on
model) load of damp clothing.
The drum is supported at the front by 4 plastic bearing pads or 1 drum support wheel and 2 bearing
pads (depending on model) mounted on the front air duct and a single bearing at the rear located in
the rear panel. A shaft fixed to the rear of the drum runs in the rear bearing.
The drum is driven by a belt, which passes around its periphery and onto the shaft of a motor secured
to the base of the dryer. The belt is elasticated and tensioned by a pulley mounted to the motor.
As well as driving the drum the motor also drives impellers (rotors), fixed to each end of its shaft.
The front impeller draws cold air into the dryer, while the rear impeller recirculates drying air. The
addition of heat to the recirculating air is provided by a heating unit attached to the rear panel, enabling
the air to hold moisture when in contact with the wet load, thus causing it to dry.
As the warm recirculating air passes through the drum it collects lint as well as moisture. To prevent
the lint from blocking the heat exchanger (condenser), the air is passed through a filter located in the
front air duct door. The filter unit is positioned so as to be easily removable for cleaning by the user.
After passing through the filter, the circulating air is dusted through passageways in a heat exchanger
(condenser) located in a housing on the base of the dryer. Cold air is drawn into the dryer and flows
across the heat exchanger passageways. This cold air is not mixed with the warm damp recirculating
air, but is drawn into the dryer. This has the effect of reducing the circulating air temperature, causing it
to give up its moisture. (Cold air holds less moisture than hot air.) The now warm cooling air is
exhausted through the rear of the dryer.
The moisture removed from the recirculating air is pumped to a removable container mounted in the
left-hand side of the console. The user can easily withdraw the container to dispose of the collected
condense.
There is no requirement for venting to atmosphere on this dryer.

Controls Overview
The user controls consist of a programme selection knob, option buttons and a Start/Pause button.
The control system consists of a user interface and control module, a thermistor mounted at the top of
the front air duct and one mounted on the heater assembly and a conductivity sensor.
The conductivity sensor is mounted in the front air
duct.
A single wire connects the sensor to the control
module.
The thermistors and conductivity sensor send values
back to the control module. The control module then
determines the programme duration and required
dryness of the load in a set of values for a particular
programme held within the control module software.
The combined Control and Power Module is a single
unit located at the top front right hand side of the dryer directly behind the console panel.
This module does not have a standard service port, and requires the use of a Low End Adaptor to
connect the Hardware Key to permit module programming.
The control module must be programmed with the relevant eeprom file if the control module is
replaced, the eeprom file becomes corrupted or if an updated file becomes available.
Programme Duration:
Once the programme has started the module will determine programme length for the size and type of
load. This detection is made within 10 minutes of the start of the programme and is achieved by use of
the front thermistor, rear thermistor and conductivity sensor. The module will then adjust the
programme time accordingly.
If the clothes are not sensed as dry when the 10 minute Cool Tumble period is reached, the module
does not start the Cool Tumble but continues to dry the clothes until the value from the conductivity
sensor indicates that the clothes are dry. The programme then advances into Cool Tumble.
Maximum Programme Period:
If after the maximum permitted programme time of 300 minutes (Note: this is an internal default value.)
the clothes are still not sensed as dry, the programme advances to Cool Tumble and completes the
programme. No fault is indicated if this occurs.
Heater Control
The control module also controls the heater. This has an upper and lower element. The lower (static)
element is permanently energised (except in cool tumble) and the upper element (dynamic) is cycled
on and off by the control module during a programme to maintain the correct temperature within the
drum for the programme selected.
If the user turns off the power or disconnects the mains cable or there is a power cut, the dryer will
remember its last settings and resume the programme when the start button is pressed.
If the event of a controls or thermistor failure, a cycling thermostat and one-shot thermostat are fitted
as safety devices.

FUNCTIONS DESCRIPTION
The Drying Guide allows you to consult a user friendly table of fabric types and load capacities.
The PROGRAMME knob sets the programme: rotate it until the indicator is pointing to the programme
you want to select. This will also power the dryer to the ON state. This replaces the On/Off button
found on previous models.
When either ’OFF’ (Hotpoint models) or the knob marker ’()’ (Indesit models), is positioned in the 12
o'clock position, it turns the machine Off and Cancels the Programme.
The OPTION buttons/lights select available options for your selected programme. The lights indicate
that the option has been selected.
The START/PAUSE button/light starts a selected programme. When you press this button there
will be one beep and the progress lights will flash to confirm the action. When a programme is running,
holding this button in pauses the programme and stops the dryer.
The light is green when programme is running, flashing amber if the programme has been paused or
flashing green if on stand-by waiting to start a programme.
Stand-by Mode
30 minutes after a programme has finished, if the dryer is still 'On' and no buttons have been touched,
the dryer will go into Stand-By mode. The LEDs and display will switch off. To reactivate and to remove
the dryer from Stand-By mode, turn the Programme Selector to position "1".
It will take a few seconds to recover from "Standby".
Another programme can be started or the dryer switched off by turning the selector to the OFF position.
The Progress or Delay lights show you the status of the programme, or the delay time when they
flash. During a delayed start the lights flash to show the delay selected. When (not flashing) they show
each stage of the programme by the corresponding light turning on.
The Empty Water indicator light signals that the water container should be emptied. The light will take
a few seconds to go out after replacing the empty water container, the dryer must be running for this to
happen. Note: If the water bottle fills the indicator light flashes, the heat is turned off and your clothes
will not dry.
The Clean Filter light gives you a reminder before every programme that it is essential to clean the
filter every time the dryer is used.
The Clean Condenser light gives you a reminder that it is essential to clean the condenser at regular
intervals.
