6 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. 2 Filter Water container Condenser Unit Rear Tap Condenser unit Catches Handle Condenser cover Air intake Front 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. 6 of 34

7 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 Air 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. Magnet fixed to sensing strip inside the drum Ring terminal end fixed under air duct screw Routing of wire and resistor.

10 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. 10 of 34

11 Thermistor Tables When testing these Thermistors make sure you have selected the CORRECT resistance range on your test meter for the value you expect to see. The resistance value varies with temperature. FRONT THERMISTOR REAR THERMISTOR Temperature C Resistance KΩ Temperature C Resistance KΩ Example: Front Thermistor If the ambient temperature where you are testing is 15 C you would expect to get a reading of approximately 80.40KΩ. (If the thermistor has warmed up because of handling or operation of the dryer then the meter reading will be a lower value) The Rear Thermistor is a different component with a different specification - refer to the chart of 34

17 DRYER OVERVIEW Introduction of Simplified Electronics These Models are fitted with a new Electronic Module, which is fixed to a plastic carrier, located behind the Console. Plastic Water Shield (if fitted) Low End Adaptor Connection point Control Module Fluff Barrier Drum This Module replaces the Control Module (previously located in the Base), the Display Module + Control Interface (previously located behind the Dashboard) and the Module to Display interface harness, fitted to 2013 Production Tumble Dryers. It is NOT interchangeable with earlier products which use 2 modules. The module is covered with a white plastic water shield which must always be fitted correctly and retained with its fixing clip. Programming Connector The module is programmed using Memwriter and a Hardware Key or with a SmartCard Reader and Card, connected using a Low End Adaptor. (See pages 27 & 28 - Contol Board Programming) These models have an Auto Test Cycle. See pages 7 & 8. Fault Codes These Models do NOT display a fault code if the dryer is in a Fault Condition. See page 6. Low End Adaptor connector 17 of 34

18 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.

19 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. Drum Support Wheels 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. Conductivity Sensing Strip Bearing Pads 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. 19 of 34

20 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. 20 of 34

21 USING THE DRYER 1. Load the Dryer with Laundry 2. Turn the Power On to the Dryer 3. Turn the Selector Knob to the required Programme - this will turn the Dryer On and select the programme in one action. 4. Set any required options - if available 5. Push the Start/Pause Button to begin the programme. Note: Turning the programme knob to another programme after the cycle has started will NOT change the cycle to the new programme. You must cancel it first. Cancelling a Programme To cancel a programme turn the selector knob to the OFF position and wait until it ends. Then you can select another programme. Automatic pre-post Crease Care This is an automatic function which provides an anti-crease treatment both before and after the drying programme. By periodically rotating the drum before the start of the drying cycle, when a delayed start is selected, the formation of creases is prevented. On certain programmes the drum also rotates periodically at the end of the drying cycle. The phase is stopped when the door is opened or when the knob is set to OFF. 21 of 34

22 OPTION BUTTONS Note: Some buttons are disabled by software when their selection is not appropriate. Start/Pause This button is used to start every programme or to continue a programme if the door has been opened and then closed, or if there has been a power interruption. Pressing and holding in this button when a programme is running cancels the programme. Low Heat This Option can be set on Timed Cycles and some automatic Cycles. If the Option if not available, when the button is pushed the LED will flash and a beep is heard. When the Low Heat Option is enabled, the Target Heating Temperature is Reduced - therefore the clothes will take longer to dry. Alarm When this Option is set the Buzzer Sounds at the end of the Drying Cycle to Signal that the programme has ended and the garments are ready to wear. 22 of 34

23 PROGRESS, ADVICE & WARNING LAMPS Clean Filter / Empty Water Container LED LED On - Reminder to empty the water container and clean the filter. The filter must be cleaned after every use. LED flashing and buzzer sounds - The water container must be emptied immediately and the dryer restarted. The flashing LED indicates the container is full and the dryer will turn the heater off. After restarting, the LED will take a few seconds to go out. Clean Condenser LED The LED comes on every 20 cycles to remind the user that the condenser must be regularly cleaned. The cycling on of the clean condenser LED is only controlled by the control module and is displayed as a reminder. This dryer does not sense the state of the condenser. Progress Lamps Drying Cool Tumble End During Drying Cycle: Denotes the dryer is drying the clothes Denotes the dryer is on the Cool Down period Denotes the cycle has finished. 23 of 34

24 COMPONENTS Door The door is constructed of several components, the outer shell being powder coated metal. And an inner lining consists of a moulding that clips into position on the outer door shell. The hinges are reversible, the extra holes on the opposite side of the front panel being filled with blanking plugs. The blanks need removal before changing the hinge side that can be completed by diagonally transposing the hinges. Filter Comprises of a plastic mesh moulded into its housing, which slides into the front air duct. Door Switch Normally open single pole microswitch activated by the door on closure. This is the first switch in the electrical Water container circuit and therefore its rating, corresponds to the full loading of the product. Control Module This is an Electronic Device that monitors and controls all devices within the tumble dryer. A production module is pre programmed at the factory with the relevant programmed file. Service Modules are supplied non programmed and it is necessary for the Module to be programmed by the Service Engineer. See pages for Module programming. Filter Drum The drum comprises of a zinc coated front and rear body and two removable plastic lifters. The rear of the drum is perforated to allow the passage of air. Fixed to the rear pressing is a support shaft which runs in a bearing located in the rear panel of the dryer. A drive pin and collar on the drum shaft prevents forward thrust during use. The front lock seam of the drum rotates on front drum support wheels. Condenser cover handle (pull to open) Air intake grille Rating plate Model & Serial Numbers The drum has a patterned finish to allow for better air circulation within the drum. Curved Drum paddles give extra garment care. Patterned drum from a model fitted with a stainless steel drum Rear Thermistor Fitted to the heater assembly above the heater. Used by the electronics for controlling the temperature into the rear of the dryer. Front Thermistor Fitted to the bottom of the front air duct moulding, used by the electronics for controlling the temperature. One-Shot (Safety) Thermostat (White Spot) 24 of 34

25 This device is a disc type thermostat set to operate at 143 C. It is used as a Safety Device. It is positioned above the element. If this device fails it cannot be reset. Cycling Thermostat ( 120 C +/- 3 C ) The cycling thermostat is mounted adjacent to the one-shot (safety) and is designed to open at 120 C. It limits the temperature of the heat entering the drum. Heater Unit ( for Condenser models = 2.3 kw ) Consists of coils wound on 'mica' supports, which are supported by mica end insulators. These end insulators fit into a steel pressing that also locates the rear thermal controls. This is fixed by screws to the rear cover. This pressing also forms air guides. The heater elements thermal controls, thermistors and rear cover are supplied as an assembly and has a 5 - way and a 2 - Way connector provided to interface with the electronic module. The heater has upper and lower heater sections. The lower (static) heater is permanently energised and the upper heater (dynamic) is cycled on and off by the control module during a programme to maintain the correct temperature for the programme selected. See page 12 for Heater Technical information. Motor A two pole P.S.C running at 2800 rpm with the impeller fitted to the rear end of the shaft and the drive belt running directly in grooves in the front end of the shaft. It is protected from overload by a self-resetting internal cut-out that interrupts the electrical supply to the windings. It is used together with a capacitor that is mounted on the base of the dryer. Pump & Float Switch Mounted on the bottom right-hand side of the rear panel, condensate water from the condenser chamber is pumped via an external hose to the water container situated behind the console. Operation of the Float Switch (water container full) When the water container becomes full, the excess water is diverted back into the pump reservoir, which causes the float to rise and the operation of the micro switch signals the module, the container is full. After 2 minutes the machine will stop with the Start/Pause LED Flashing and the Empty Water LED illuminated. Drum Rear Seal This unit comprises of a ring of foam with a webbing bearing face. Lubrication is applied to the drum where the webbing surface runs, to reduce noise and wear. The seal reduces air losses at the rear of the drum. The joints in the foam are sealed with glue and the joints in the webbing are stitched to further reduce air leakage. Drum Earthing Drum Earthing is obtained by the teardrop bearing fixing screw. NOTE: - It is important that the correct screw is always used to secure the teardrop bearing. Earth Screw Teardrop bearing 25 of 34
