1.0INTRODUCTION

1.1HOW TO SERVICE SMARTDRIVE

IF SMARTDRIVE HAS NO POWER - SEE SECTION 6.1

Power off at the mains socket. Wait 2 minutes. Power on.

IF SMARTDRIVE IS DISPLAYING A FAULT - SEE SECTION 11.0

This may be identifiable by an unusual combination of LEDs displayed on the wash progress LEDs. Smartdrive will be making a continuous sound of beeping repeating once every second and will be PAUSED. Phase 1-3 Only press spin buttons until the SPIN HOLD and SPIN SLOW LEDs are on. The wash progress LEDs correspond to the 8 bit binary fault code with the spin LED representing the least significant bit. On LW or AW leftmost LED may be obscured by the front panel overlay, this is the most significant bit. (NB. The LEDs will not be flashing).

IF SMARTDRIVE IS DISPLAYING A USER WARNING

– SEE SECTION 10.0

This may be identifiable by an unusual combination of LEDs flashing and / or Smartdrive may be making a rippling sound of 5 beeps repeating every 6 seconds.

IF SMARTDRIVE APPEARS TO HAVE NO FAULT

Find the last fault. It may be accessed from Diagnostic Mode. Diagnostic mode is accessed by pressing ‘Wash Temp Down’ and ‘Power’ buttons together, Smartdrive will give 2 quick beeps in acknowledgement. (Phase 1 & 2 Only press ADVANCE key once). Go to level 3 by pressing the Spin buttons until the SPIN HOLD and SPIN SLOW LEDs are on. The wash progress LEDs correspond to the 8 bit binary fault code with the spin LED representing the least significant bit.

This fault would have occurred within the last 8 cycles. If all the wash progress LEDs are off, there is no fault. Do not change Motor Controller. If there is no fault, (above) and the product will not start check that the lid switch is operating correctly. This may also be done from Diagnostic Mode, see SECTION 8.2.

Set Restart OFF, (activate the Low Water LED while in Diagnostic mode). This will allow Smartdrive to detect faults quicker, it will not retry. Exit Diagnostic mode.

Test Smartdrive by filling (using both valves), draining and spinning to 1000RPM. Open lid when at 1000RPM. Check the size and the operation of the Out of Balance lever.

IF SMARTDRIVE WILL NOT START it could be that the lid switch indicates that the lid is open.

IF SMARTDRIVE IS LEAKING – SEE SECTION 6.4

IF SMARTDRIVE IS NOISY – SEE SECTION 6.5

IF SMARTDRIVE HAS OTHER FAULTS

– SEE SECTION 6.0

If you have Smarttool, it will identify the last four faults and the last user warning. It will provide appropriate servicing instructions.

- 1 -

1.2 SMARTDRIVE SERVICING – Quick Reference Guide!

Smartdrive is not isolated. Even low voltage (5v and 15v) are live!

During normal operation only one LED should be flashing. This is the leftmost wash progress LED when Smartdrive is Paused.

The product has a diagnostic mode which allows the fault information to be displayed.

Diagnostic mode level 3, indicates last fault. If there are no wash progress LED’s ON it would be most unlikely that the Motor Controllers has failed

Motor Controllers and displays of different phases are different colours. Both motor controller and display must be of the same colour to be compatible.

Phase 1 to 4 motor controllers used water to cool the electronics. The water temperature is regulated by a thermistor within the motor controller.

Phase 5 motor controllers use the pump to generate the low voltage power supply. If the pump is disconnected Smartdrive will appear ‘dead’.

Phase 1 (spare), 4 & 5. When replacing Motor Controllers the size must be set, otherwise fault code 9 will occur when the product is started.

When reconnecting the internal pressure hose ensure the product is empty of water.

Water inlet flow problems are normally indicated by HOT &/or COLD LED’s flashing, this could mean the taps are off or the filters blocked.

Inlet hose filters should be fitted with the dome pointing into the flow of the water on the tap end of the inlet hose.

If the drain hose is pushed too far down into the standpipe Smartdrive could siphon during rinse.

The motor has a direct drive and has no gears. There have been 3 different stators and 2 different rotors since introducing Smartdrive.

The inner bowl floats when the product is full of water.

The inner bowl has balance rings which have sealed compartments full of water. These self balance the bowl during spinning.

The pump has a thermal cut out which can take up to 15 minutes to reset. This can occur during a pump block, fault code 37.

When servicing the pump consider fitting a pump hood kit to Phase 2-5. See WM013 in Appendix B.

When servicing a 5kg Smartdrive pump consider fitting or a pump shield p.n. 426292. Phase 1-4. See WM81 in Appendix B.

When servicing Phase 2-3 Smartdrive consider fitting a condensation kit to the console area. See WM80 In Appendix B.

Option Adjustment Mode. Press START/PAUSE and hold POWER.

Diagnostic Mode. Press WASH TEMP DOWN and hold POWER.

Size Setting Mode. Press WASH TEMP UP and hold POWER.

Warranty does not cover problems caused by the user, for example ‘user warnings’. Pump blocks are not covered by warranty.

Between 1995 and 2000 50% of Motor Controllers and Display Modules returned to Fisher & Paykel were not faulty.

Service information is available on the internet at the following web address www.fisherpaykel.com/Service Get appropriate usernames and passwords from your ASC’s. Smarttool is used to diagnose fault information and may be downloaded from this web address. This is available as a PC application or on a palmtop. The data is optically transferred from Smartdrive, ActiveSmart(Fridge), and DishDrawer(dishwasher) using a light pen from a front panel LED.

Safety testing should be carried out in accordance with standard electrical testing procedures. The resistance from the earth contact on the mains lead to the wrapper should not exceed 0.5 ohms. The insulation resistance should also be measured at 500 volts DC between phase & neutral to earth. The maximum resistance should not exceed 1Mohm.

3.0 INSTALLATION

REMOVING BOWL PACKER AND ACCESSORIES

Remove the outer packaging. Leave Smartdrive standing upright.

Lift the lid and remove the bowl packer. Remove hoses and accessories.

REMOVING TRANSIT RESTRAINT

Rotate the agitator anti-clockwise for 3 revolutions. (This unscrews the transit restraint from the base of Smartdrive.) The wash bowl will then be free to move from side to side.

Remove the bottom cardboard packer. Tilt Smartdrive and check that the red transit restraint has come away with the packer.

Keep the transit restraint and packers for future use.

Please make sure the transit reestraint has ben removed before operating Smartdrive

INSTALLATION

In Smartdrive there is a bag with:-

4 rubber inserts for the levelling feet

4 sealing washers (2 with filters)

1 hose guide

INLET HOSES

Place filtered sealing washers into the straight ends of the white inlet hoses and connect to taps. (Dome end of washer towards tap.)

Place sealing washers into elbow ends of the white inlet hoses and connect to inlet valves. Inlet valves are marked on the back of Smartdrive.

H = Hot C = Cold.

NB. The new inlet hoses have the filters and washers fitted.

Cold Supply Only

If you only have a cold water supply, an inlet valve cap (blanking cap) MUST be connected to the hot inlet valve. The cap prevents water leaking out the hot valve. The cap is Part No. 388491.

DRAIN HOSE

Pull the black drain hose out from the back of Smartdrive by pulling the exposed part of the hose downwards and outwards. The hose guide guides the drain hose over the tub or standpipe. It MUST be fitted to the drain hose.

To prevent siphoning:

The drain hose should not extend more than 20 mm from the end of the guide.

The height of the standpipe or tub should be between 850-1200mm. The drain hose can be trimmed to length.

Place the drain hose in the tub or standpipe.

- 4 -

LEVELLING SMARTDRIVE

It is IMPORTANT to level Smartdrive to ensure even spin performance. Fit the 4 rubber inserts into the feet on the base of Smartdrive.

Move Smartdrive to its final position. (a minimum clearance of 20mm each side of Smartdrive for ease of installation.)

Adjust the feet so that Smartdrive is level and cannot rock.

To check if Smartdrive is level

look into Smartdrive bowl and make sure it sits slightly forward of centre.

FINALLY

Turn on the water and check all hose connections for leaks. Make sure there are no kinks in the hoses.

Uncoil power cord and plug into wall socket. If using an extension cord ensure that it is positioned so that it does not come into contact with water or moisture.

INSTALLATION ENVIRONMENT

WATER SUPPLY TEMPERATURES

For best operation the hot water should be approximately 65ºC. The cold water should not exceed 35ºC or the hot water should not exceed 75ºC. Temperatures above this may cause a fault or cause damage to Smartdrive. If there is an uncontrolled water heating source (e.g. a wet back or solar heating system) fit a Hot ‘n’ Safe Valve. This will ensure the hot water temperature remains within safe limits.

Hot ‘n’ Safe Valves available are:- RMC TVA 75HF (3/4 inch pipe) RMC TVA 50HF (1/2 inch pipe) Adjustable between 35ºC - 65ºC RMC TVA 50HP (1/2 inch pipe)

For instantaneous gas hot water supply.

LOW INLET WATER PRESSURE

A slow flow rate (less than 5 litres per minute) into Smartdrive will be improved by fitting large bore inlet hoses p.n.426123.

DRAINING

Check that the standpipe or tub are free from lint and other obstructions.

Draining must comply with local by-laws.

SAFETY

Smartdrive is not intended for use by young children or infirm persons without supervision. Never reach into Smartdrive if the wash bowl or agitator is moving. Press START/ PAUSE and wait until Smartdrive has completely stopped before opening the lid.

4.1Electronics Systems

Smartdrive electronics consists of 4 mains parts: - a) Motor, (b) Motor Controller Module, (c) Display Module and (d) Rotor Position Sensor. The interconnections are shown in the block diagrams below:-

Wiring diagram for Phase 1. NB. Phase 1 (spare) uses a motor controller similar to Phase 2-4.

Wiring diagram for Phase 2-4. NB. Most of phase 2 did not have a reed switch, a white wire loop was connected in place of the blue & black wire.

PHASE 5

WIRING DIAGRAM

- 8 -

4.2Motor

The motor is a 3 phase, 42 pole, DC brushless motor, commutation is achieved electronically. The Motor consists of a STATOR (stationary part) and ROTOR (rotating part). The Rotor Position Sensor controls the speed and position of the motor. The STATOR has a 'star point' connection, and motor terminals. The Star point connects the 3 windings to a common point. The DIRECT DRIVE motor has eliminated the need for gearboxes, pulleys and belts. The Rotor is connected via a single shaft to the agitator. The single shaft design also eliminates the need for extra seals which are needed in conventional multi shaft designs.

Stator. 3 different types. Phase 1, Phase 2-4 and Phase 5. The contact sizes for the Phase 1 and 2-4 stators are the same. Phase 5 stator has smaller contacts.

Rotor has 2 different types Phase 1 and Phase 2-5.

Fault Codes 130,131,132,133,134,136 are directly associated with the Motor. Always check the resistance of the stator. Ensure that the rotor

is stationary when measurements are made.

If the resistance is low always replace the stator. Remember if the stator is hot the resistances can increase by as much as 30%. Check the brass star point is not cracked or intermittent.

Connect the 3 stator connectors the correct way round, otherwise the motor will not run and give fault code 136. The stator is marked “R B Y”.

Resistance measured at the Motor Controller is twice resistance per winding eg between red and blue is:

Phase 1 1.3 + 1.3 = 2.6 ohms Phase 2 to 4 6.1 + 6.1 = 12.2 ohms Phase 5 16 + 16 = 32 ohms

Replace if broken (425104). Rotor may be tested with RPS Tester. A complete rotation will test all the magnets. A rotor with cracked or chipped magnets will work fine. A rotor should only be replaced if it has been run over by a bus, (especially phase 1). However, some early phase 5 rotors may cause noise on wash and a replacement may rectify this.

Two clamp plates are used to secure the stator, one on each side. The four bolts are tightened to a torque of 5 Nm. NB: Early Smartdrives had a clamp plate that was riveted, these should not be mixed with the later clamp plates which are ‘lanced’. The plastic nut for securing the rotor requires a 16mm socket and should be tightened to 16 Nm. If the nut is broken use puller p/n 502034.

4.3Motor Controller Module

This module contains the circuitry needed to control the water valves, pump and the motor. It also recieves signals from the rotor position sensor, pressure sensor and the display module.

The Motor Controller Module and Display Module are continuously communicating. The Motor Controller Module supplies the Display Module with 15v (11v min 17v max). The two Modules are connected together with a 3 way harness, (Phase 1-4), or a 4 way harness, (phase 5).

The electronics in the Motor Controller Module, (Phase 1-4 only) are cooled by water, Phase 5 is air cooled. The inlet chamber is a separate part to the Motor Controller Module. The inlet chamber serves two purposes: -

Phase 1 to 4. Water cooled. During filling, water is flowing through the chamber continuously and cooling the electronics. During spin cycles, if the electronics becomes too hot, the cold valve will purge. A small quantity of water may be discharged into the bowl during the cycle.

Mixing the incoming hot and cold water is part of the automatic wash water temperature system. A thermistor measures water temperature and enables the water temperature to be controlled.

The Motor Controller Module contains an EEPROM which stores information on Smartdrive operation such as faults and diagnostic information. Information on the last fault is retained in the memory. This memory is also used to store Favourite Cycle data, Optional Adjustments Mode data (see later) as well as special data stored during manufacture. All this memory will be retained when Smartdrive is powered off.

If Motor Controller has No Power. See Section 6.1.

Phase 1. Original Motor Controllers have a replaceable fuse. 6A 32mm slow blow. For diagnostics see WM51 in Appendix B.

Phase 1 (spare) these are essentially Phase 4 functionality. See WM011 in Appendix B.

Phase 1, 425775. These modules stirred at 30 RPM because Smartdrive was noisy. Replace suspension rods is a better solution. 425775 is now obselete.

Phase 2-4 check that a blade divider (p.n. 425842) exists within the heatsink.

Phase 4-5. When replacing Motor Controllers ensure that size setting mode is entered to set size.

Phase 1-3. When replacing Motor Controllers enter option adjustment mode to set size.

The colour of the Motor Controller identifies the phase and must match that of the display. Blue (or white) is Phase 1, Blue is Phase 2. Green is Phase 3. Yellow is Phase 4 and grey is Phase 5.

Pressure pipe must only be reconnected when the bowl is empty of water, otherwise the bowl will flood. Blow down pipe to release any water droplets before reconnecting.

Smartdrive is not isolated. Even 15v will be live.

Phase 1-4 use water cooling. Dry out topdeck area before refitting.

Phase 5 has a standby mode. The 15v will power off at the end of the cycle or after 15 minutes without use. The power button must be used to wake up Smartdrive.

Phase 5 uses the pump as part of the power supply. If the pump blocks Smartdrive could power off!

Water Level Measurement - Pressure Sensor

Smartdrive is fitted with a pressure sensor which can fill to any water level. The pressure sensor is incorporated within the Motor Controller and cannot be removed. The pressure pipe connects from the Motor controller to the air bell at the bottom of the outer bowl. It is part of the harness assembly. On Phase 1 the pressure sensor is on the Display Module.

- 10 -

4.4Display Module

The Display Module contains a microprocessor whose function is to take the inputs from the front panel and send the appropriate command to the Motor Controller Module. It also controls the output to the display LEDs and beeper.

Test the Display LEDs. Power on at the wall. This illuminates all LEDs for 2 seconds. Check the operation of all the switches and check the appropriate LED lights.

If not all LEDs illuminate check that the LEDs are not bent. Open up housing, (with power off) and reposition the LED.

Replace if there is any sign of corrosion on the Display Module. This is one of the most likely causes in older Smartdrives.

The display has up to 4 hidden modes where the function of the buttons is different. Option adjustment mode, Diagnostic mode, Size Setting mode and Demonstration mode.

On Phase 1 and early Phase 2 the Display Module was fitted with the lid switch. Check it activates correctly onto the plastic ‘button’ in the console.

Phase 1-3 were fitted with a size switch. This was a two pronged switch which was activated by the console. This determined the size of the product and is located at the bottom in the middle. The size must be set in EEPROM by accessing Option Adjust mode.

Phase 4-5. When replacing these displays & Phase 1(spare). Size Setting Mode see section 9.0.

3 different display modules, LW, MW and GW. The AW is fitted with an LW display.

Phase 3-5 GW has ‘Auto Water Level’. Phase 2-5 GW has ‘Delay Start’.

Colour of the display identifies the phase. Blue (or white) is Phase 1 and 2. Green is Phase 3. Yellow is Phase 4 and grey is Phase 5. The phase and colour of the display must match that of the Motor Controller.

Phase 1 (spare). See WM011 in Appendix B.

Pressure sensor and EEPROM on Phase 1 is in display, (not phase 1 spare).

Condensation kit may be fitted to phase 2-3 Smartdrives see WM80 in Appendix B.

4.5Water Valves

The electronics control the water valves so that a constant water temperature is achieved in the bowl irrespective of the temperatures and pressures of the household hot and cold water systems. To achieve accurate water temperatures a proportional water valve is used on the cold water inlet. Unlike conventional water valves which are either fully on or fully off, the proportional water valve can be controlled so that it can turn on at any water flow rate between fully on and fully off.

Always check the resistances when replacing the Motor Controller. If the resistance is low always replace the water valve. Remember if the valve is hot the resistances can increase by as much as 50%. The fault numbers associated with the water valves are 33, 48, 49 and 50. If inlet water is 5 litres a minute flow or less, flow restricting washers may be removed from water valves. Large bore inlet hoses p.n. 426123 should be used in these circumstances.

The water valves may be manually turned on from Diagnostic Mode. Press ‘Wash Temp Down’ and ‘Power’ buttons together. Phase 3 Only press ADVANCE key once. The ‘Wash Temp Down’ button turns the cold water valve on or off. The ‘Cold Water’ LED will turn on. The ‘Wash Temp Up’ button turns the hot water valve on or off. The ‘Hot Water’ LED will turn on. NB. Phase 2 it is possible to latch water valves on in this mode. Power off at the wall to resolve.

- 12 -

4.6Rotor Position Sensor

One of the inputs that the Motor Controller Module needs in order to determine which switches to turn on, is the position of the Rotor. This information is supplied by the Rotor Position Sensor (RPS).

On the RPS there are three Hall Sensors. These detect the magnetic field of the individual magnets in the Rotor. As the motor turns, the position of a group of magnets is detected. There are 5 wires on the RPS, 2 for power supply and 3 signal wires. Data on the position of the Rotor is supplied to the microprocessor in the Motor Controller Module via the three signal wires.

A single RPS p.n. 426221P may be used on all phases of Smartdrive.

The RPS is static sensitive. ESD precautions must be taken when handling this device.

Do not remove the printed circuit board from the plastic housing.

Do not use a multi-meter to check the resistance of the sensors. This may result in damage.

To test the RPS use a RPS tester p.n. 502105 and manually rotate the agitator. This tester requires adapters, see Appendix D. It requires a 9v battery to operate. The tester has 3 LEDs. A pass is when 1 or 2 LEDs are illuminated at a time. 0 or 3 LEDs illuminated indicates a fail. Any flickering of the fail LED will indicate that the RPS or rotor is faulty. A faulty rotor would give a fail at certain points of rotation. This tester does not test all the functionality of the RPS. It tests the 3 outputs but cannot indicate all faults, for example if a capacitor on the RPS is cracked.

Conformal coating has caused contact problems on the edge connector. Pushing the plug on and off a few times should clean the contacts.

Fault codes 53, 130,131,132,133,134,136 are directly associated with the RPS. Test with a RPS tester. Check the strain relief for the harness. If there is any sign of corrosion replace RPS. If there is an indication of a ‘flash over’ from the RPS to the stator there will be a black mark on the RPS. The Motor Controller will have blown up.

Installation

Refer Section 12.3 for advice on motor removal and installation. Unclip the RPS module from the stator and slide it out.

When refitting, line up the arrows on the RPS and Stator. Slide the RPS into the Stator poles until the clip locks into the notch on the other side of the Stator.

Refit RPS harness into strain relieving labyrinth. NB. Early Smartdrive models did not have this strain relief. If this is the case, secure harness carefully using a cable tie or replace RPS.

- 13 -

4.7Pump

The drain pump motor is coupled directly to the base of the outer bowl. This eliminates bowl to pump hoses and the accompanying seals, clips etc. The pump housing is an integral part of the outer bowl. The pump is accessible by removing the inspection hatch on the front of Smartdrive, (Phase 1 to 4 only). It is also accessible from the top by removing the agitator and inner bowl. Phase 5 uses the pump as part of the power supply. If it is not connected, (or thermally tripped) Smartdrive will not power up. A fan is mounted on the underside of the pump. This is necessary to keep the pump cool. The impeller, on the top of the pump, pumps the water. Phase 5 pumps the water with a 10 second on, 1 second off timing, this helps clear the pump of lint.

Flow Rate 24 L a minute @ 1m Head Pump motor resistance

Phase 1 & 2 (SELNI) 33 ±3 ohms@ 20oC

Pump block, fault code 37 is the most common, see section 12.4 for more information. Always clear the pump from inside the inner bowl when this fault is reported.

Older pumps may leak along the shaft. If there is any sign of leakage the pump should be replaced. Always check the resistance of the pump windings. If the resistance is low always replace the pump. If the pump is hot the resistances can increase by as much as 30% before the pumps thermal cut out trips at 110 oC. This can take 15 minutes to reset. The cut-out should only trip if there is a blocked pump. Ensure there is a plastic fan on the underside of the pump. Burnt out pumps can be a result of a leak in the pump seal to the outer bowl. Check for signs of leaks in the pump area. Other fault codes are 12, 13, 14, 44 and 62.

The pump may be manually turned on from Diagnostic Mode. Diagnostic mode is accessed by pressing ‘Wash Temp Down’ and ‘Power’ buttons together. Phase 3 Only press ADVANCE key once. The ‘Regular’ cycle button turns the drain pump on or off. The ‘Regular’ LED will light when the pump is on. Use to drain the bowl.

When removing the pump up to a litre of water may leak from the pump cavity. When replacing pump lubricate the top section of seal diaphragm. If servicing a pump block, a Pump Hood kit, (see WM013 in Appendix B), should be fitted to all Smartdrives since late phase 2. This is an enhancement and will reduce further pump blocks, it includes a VORTEX impleller, see above diagram. The screw securing the pump hood to the inside of the outer bowl must be secured tightly. A pump shield (p.n .426292) should be fitted to all 5kg Smartdrives that are not fitted with one, (typically phase 1 to 3). A Comprecci pump is now replaced by a Selni pump. If replacing a Comprecci pump with a Selni pump an insulating divider p.n. 425890 is required to be fitted between the terminals of the pump. The pump bracket may also be different. The pump must be earthed.

- 14 -

4.8Inner and Outer Bowls

The outer bowl is the assembly to which all the motor, pump system, suspension rods, etc are mounted. Within the outer bowl is the inner bowl and the agitator. During spin, the agitator and inner bowl have to be coupled together and turn as a single unit. In agitate the agitator and inner bowl are free to rotate independently.

In Smartdrive the inner bowl is free to move in a vertical direction. The position of the inner bowl is determined by the water level. At the base of the inner bowl is a flotation chamber consisting of a number of individual cells. When Smartdrive is filling with water the pressure on the air in these cells increases as the water level rises until eventually the inner bowl floats upwards and disengages the driven spline from the drive spline. This action frees the agitator from the inner bowl and allows it to move freely in both directions.

When the water is draining from Smartdrive the pressure on the air trapped in the cells of the flotation chamber decreases allowing the inner bowl to settle back down onto the drive spline and re-engage the driven spline thus allowing the agitator and inner bowl to turn as one unit. The floating bowl is also used to detect if the user has selected the correct water level for the size of the clothes load in Smartdrive.

The point at which the bowl starts to float is determined by the water level and the size of the load. The greater the load, the more water is needed before the inner bowl will float. By detecting the point at which the bowl floats, Smartdrive can determine whether the correct water level for the particular clothes load has been chosen by the operator. If the operator has chosen a level that is too low for the load, Smartdrive will override that choice and fill to the correct level. This is to ensure optimum wash performance and minimal clothes wear. If the user has selected a level that is higher than necessary, Smartdrive will still fill to the users selected level.

Diagram showing the Floating Bowl

- 15 -

Detection Of Inner Bowl Float Off Point – Bowl Check

During fill the inner bowl will rotate to ensure that the clothes are evenly saturated with water. When the chosen water level is reached, and before the agitate cycle is started, Smartdrive will carry out inner bowl float checks, (bowl check). The inner bowl will stop and commence a number of small agitate type actions. During this action Smartdrive determines if the inner bowl has floated. If it has, Smartdrive will determine the required water level and check if the operator has selected the correct level. If the inner bowl has not floated off, Smartdrive will continue filling and check again later. The water level at which the inner bowl floats off is not necessarily the same as the final water level.

Detection of Inner Bowl Re-Engagement – Bowl Check

After Smartdrive has pumped out the water, the inner bowl will sink down and re-engage onto the drive spline. To ensure the inner bowl has re-engaged correctly, Smartdrive will carry out a bowl re-engage test sequence, (bowl check). Bowl check consists of a series of short agitate type actions before the spin cycle starts. A sound may be heard as the inner bowl re-engages. The following fault codes are associated with bowl check 40, 47, 56 and 160.

Balance Rings

The inner bowl has 2 balance rings, one at the top, and one at the bottom. These are sealed compartments half full of water. This water allows the bowl to balance. If these rings are empty the inner bowl must be replaced.

Lint Removal System

The self-cleaning lint removal system works by continuous water circulation, resulting in the separation of lint from the wash water. As a result of the agitator action, lint and wash water are sucked into the agitator stem and down to the base, where they are directed into the cavity between the inner and outer bowls. The extruded holes of the inner bowl are shaped to allow the wash water to flow back into the bowl, but prevent the lint from following.

The lint then floats to the surface of the water, between the inner and outer bowls and remains there until it is flushed out the drain at the end of the wash cycle. In the spin mode, water spun from the clothes through the small holes in the bowl flushes the lint off the outer bowl and down the drain. The selfcleaning lint removal system has proved to be effective and efficient and should require no maintenance.

- 16 -

4.9Lid Switch and Out of Balance Switch

Lid Switch

If the lid is raised, the lid switch operates and stops the cycle when Smartdrive is stirring during fill or Smartdrive is spinning, (braking). The motor should stop within 10 seconds, all the energy from the motor is dumped into the brake resistor (Phase 1-4) or the pump (phase 5). It is important to understand that it can be a worthwhile test to open the lid at 1000 RPM, this will exercise the braking circuitry in the Motor Controller. If Smartdrive appears not to start it could be that the lid switch indicates that the lid is open.

The user may lift the lid during agitate to add clothes or watch the wash action. However, the motor will stop if this is tried during spray rinse or final spin, or stop during fill.

Smartdrive should pause when the lid is opened 50mm and restart at less than 12mm.

Phase 1 and 2 (most) used a mechanical lid switch located on the Display Module.

Phase 2 (Late) to 5 .The lid switch is controlled by a reed switch located under the top deck on the right hand side towards the front. The reed switch is activated by a magnet which is moulded into the lid assembly. This switch is closed when the lid is closed. Use a multimeter to check operation. The resistance should be less than 2 ohms. Ensure that the wiring to the reed switch does not get trapped in the top deck when reassembling.

A ‘recently manufactured one piece lid’ is not designed for use with Phase 1 & 2 lid mechanical switches. There is a hole at the back which does not push the lid switch lever.

Out of Balance Switch

When the Smart Drive is spinning it can sense when the wash load is out of balance and will stop and retry spinning. If Smartdrive still senses an unbalanced load it will stop, give a short burst of beeps every five seconds and the RINSE or SPIN light will flash. The load must be redistributed more evenly . However, GW and MW models have the option where Smartdrive tries to automatically correct out of balance loads. If it detects an unbalanced load, it will fill with water and agitate to redistribute the load before trying to spin up again. Smartdrive has this option turned off to conserve water, it may be turned on in OPTION ADJUSTMENT MODE.

This switch is normally closed, (phase 2-5) normally open, (Phase 1). Some Phase 1 Smartdrive were fitted with 3 terminal switches, make sure these are connected to the normally open position.

Check operation using a multimeter. The resistance should be less than 2 ohms when closed.

Fault code 43 indicates that this switch is permanently activated.

Replace switch if there is any sign of corrosion.

Phase 2. Technical bulletin WM70. Changing the OOB lever to an improved design can improve the operation of this switch.

Out of Balance and Lid Switch Test

The status of the switches may be monitored in Diagnostic

Mode. Diagnostic mode is accessed by pressing ‘Wash Temp

Down’ and ‘Power’ buttons together. See section 8.2.

- 17 -

4.10Water Temperature Sensing

Phase 1-4 uses a thermistor for sensing the water temperature. It is located within the Motor Controller. User can adjust the warm temperature by going into the Option Adjustment Mode.

Phase 5 GW uses a thermistor for sensing the water temperature. It is located in the mixing chamber. This is a replaceable item and has a resistance of 10k ohms @ 25oC. 12.5k ohms @ 20oC.

Phase 5 MW is not fitted with a thermistor. Cold water temperature is the same as the cold water supply. Hot water temperature is the same as the hot water supply. The warm water temperature is achieved by pulsing hot or cold valves. User can adjust the warm temperature by going into the Option Adjustment Mode.

Phase 5 LW & AW is not fitted with a thermistor. Cold water temperature is the same as the cold water supply. Hot water temperature is the same as the hot water supply. The warm water temperature is achieved by turning both hot or cold valves on. User can adjust the warm temperature by adjusting flow of taps.

Fault code 11 will result if the resistance of the Thermistor is outside the normal limits, the fault is probably due to an open circuit in the Sensor line. For more information on water temperature adjustment see section 7.1. If the required temperature cannot be attained a Smartdrive will give a user warning, see section 10.0 NB: Poor temperature accuracy will result if a digital water valve is used in place of a proportional valve or if the water valves have no flow control washers when used with high flow.

5.0 SMARTDRIVE INFORMATION

This information is provided to the user in the ‘Use and Care Manual’. It is included here for completeness. The user warning information and some information on Option Adjustment mode is also in this manual.

5.1Favourite cycle (GW only) – All Phases

The user may have a particular combination of wash cycle settings that are frequently used, i.e. Nappy wash, small load of Gym gear, cold water wash etc. It is possible to programme this favourite setting into the memory.

1.Press and hold the FAVOURITE button until beeps are heard and the FAVOURITE LED starts to flash.

2.Select the preferred wash cycle and other options using buttons as normal.

3.When the desired options are selected, press the FAVOURITE button again. The FAVOURITE LED will stop flashing.

4.The FAVOURITE CYCLE programme will be retained in memory even if the mains power is switched off.

5.2Customising Wash Cycles (GW only) – Phase 3 to 5 only

All the wash cycles can be mini favourite cycles. The Smart Drive can be programmed to automatically set the wash options and agitation time, when each wash cycle is selected. For instance, the user may wish to set the Regular cycle to cold wash or set Heavy Duty to include a soak. Once the wash cycles are programmed, Smartdrive will remember them, even when switched off at the wall.

TO CUSTOMISE THE WASH CYCLES

Press the wash cycle you wish to customise and hold down for 2 seconds. Smartdrive will give two quick beeps. The wash cycle light will flash telling you that you are in the programming mode.

Select your wash options.

If you would like to decrease the agitation time, press ADVANCE until the required number of green lights remain. (Each green light in the wash progress represents 3 minutes of agitation.) To increase the agitation time keep pressing ADVANCE until all the green lights are displayed again.

NB: On Heavy Duty and Wool you can only decrease the wash time

Press the wash cycle again to store your customised cycle. To change your customised wash cycle repeat these steps. NB. The customised wash cycles cannot be set to start at the rinse or spin stage or utilise DELAY START.

- 19 -

5.3Delay Start (GW only) – Phase 2 to 5 only

Select your wash cycle and options to suit the clothes load, by pressing the appropriate buttons then press the DELAY START button: -

Once for 1 hour

Twice for 6 hours (phase 2-4) 3 hours (phase 5).

Three times for 9 hour delay

Four times to cancel and return Smartdrive to normal operation.

Smartdrive will now automatically start after the appropriate delay time. The flashing of the wash progress LED will stop when the DELAY START is selected.

5.4Auto Water Level (GW only) – Phase 3 to 5 only

Smartdrive automatically selects the appropriate water level for the load when AUTO Water Level is selected. During fill Smartdrive pauses occasionally to sense the water level. Smartdrive checks if the water level is correct by using a series of 2 different agitate strokes. A slow stroke to sense the load and an agitate stroke to mix the load. If the lid is lifted during fill Smartdrive will pause. If Smartdrive detects that that water level is too low it will fill with more water and check the level again.

When washing an unusual load e.g. large bulky garments, pillows, it is recommend that the water level is manually selected .

Manually select the water level if there is already water in the bowl.

If Smartdrive does not fill to the correct level, the water level that Smartdrive selects can be modified using Option Adjustment Mode.

MANUAL WATER LEVEL SELECTION

The agitator has 5 levels marked on its stem that can be used to help the user select the correct water level. Select the correct water level by using the mark nearest to the top of the clothes.

The levels marked on the agitator are a guide for the clothes and do not correspond exactly to the water level.

Smartdrive may occasionally add water during agitation. This is to maintain the water level due to the release of air trapped in the garments.

5.5Water Saver (GW only) – Phase 3 to 5 only

The WATER SAVER option is used to minimise the amount of water used during a Regular or Heavy Duty wash cycle. When Water Saver, is selected Smartdrive alters the rinse to a give a shower rinse. A shower rinse alternately showers the clothes with water and spins them to remove the sudsy water.

The Water Saver option is not designed to be used with fabric softener. The shower rinse does not use a deep rinse so it cannot dispense fabric softener correctly.

There are some wash loads that may not suit being washed using the Water Saver option. For example, loads that have a lot of sand or sawdust etc in them, or garments where the colour still runs from them.

Smartdrive will spin slightly longer.

The Time Saver or Soak option can be used with the Water Saver option, push the wash options button until both options have been selected.

NB. Water Saver is only available on the Regular and Heavy Duty cycles. If Water Saver is selected on the Wool, Delicate or Permanent Press cycle Smartdrive will skip this option.

5.6Fabric Softener Dispenser – All Phases

The fabric softener goes into the dispenser on the top of the agitator. The dispenser is designed to automatically deliver softener into the final rinse.

Here's how it works on the Heavy Duty, Regular and Wool Cycles.

1.Fabric softener remains in the dispenser cup during the fill, agitate and drain phase of the wash programme.

2.During the first phase of the spray rinse it is centrifuged out of the cup into the body of the dispenser.

3.The fabric softener is held hard up against the sides of the dispenser body by centrifugal force throughout the spray rinse.

4.At the end of spray rinse the softener drains out of the dispenser, down the centre of the agitator where it is dissolved in the incoming deep rinse water.

For the Delicate and Permanent Press cycles the fabric softener remains in the dispenser cup throughout the wash and first deep rinse. Smartdrive then spins to release the fabric softener, delivering it down the agitator stem as Smartdrive fills for the final rinse.

Scrud

If fabric softener is used regularly it will eventually cause a build up within the outer bowl. This can result in black flakes present in the wash load. If this is a problem it is recommended that Smartdrive is periodically filled with hot water, add dishwasher powder and left to soak .

- 21 -

5.7Wash Performance Information – All Phases

Creasing

Creasing can be caused by Over loading Smartdrive or the dryer. Permanent Press or Delicate cycles have been designed to minimise creasing, they use a lower spin speed. Do not leave wet clothes to sit in the washer or laundry basket.

Soiling

Soiling is the result of insufficient detergent for the load. White clothes are better washed separately. Separate light and heavily soiled items, as clothes can pick up soil from dirty wash water. Cold water wash is too cold, Cold water below 20oC does not wash effectively. Select the wash temperature according to soil type. For example, blood and mud are better washed in cold water, while sweat and oil based soil wash better in warmer water. Over loading Smartdrive. Loads made up of articles of varying sizes will wash better (e.g. full loads of sheets may not wash that well). Hard water requires more detergent than soft water.

Linting

Wash lint givers e.g. towels, flannelette sheets, separately from lint collectors e.g. synthetic fabrics. Over loading Smartdrive can increase the likelihood of linting. Not enough detergent to hold the lint in suspension. Over drying synthetic fabrics in a dryer can cause a build-up of static electricity and result in the fabrics attracting lint.

Detergent residue

Over loading Smartdrive can result in detergent residue being caught in the creases. If this occurs, decrease the load size. Some detergents need to be pre-dissolved, check the instructions for the detergent. Cold ambient temperatures, cold washes or short agitation times may not let the detergent dissolve properly. In these cases pre-dissolve the detergent. Overdosing of detergent can also cause residue when foam breaks down to give white specs. Poor quality detergents can result in residue.

Black marks on clothes

A build up caused by the interaction of fabric softener and detergent, (scrud) can flake off and mark clothes. Do not use too much fabric softener, maximum 75cc. If this is a problem it is recommended that Smartdrive is periodically filled with hot water, plus 1-2 cups of dishwasher powder and left to soak.

Grey marks on clothes

Not enough detergent for the amount of soil on the clothes, can result in grey marks on clothes. If this is a problem it is recommended that Smartdrive is periodically filled with hot water, plus detergent and left to soak.

Dye transfer

Wash and dry non-colourfast clothes separately. Non colourfast clothes left sitting in a washer or laundry basket can transfer dye to other clothes.

Tangling

Washing with too much water (i.e. under loading) can cause the clothes to tangle around each another. Do not load Smartdrive by wrapping clothes around the agitator.

6.0SMARTDRIVE PROBLEMS

6.1If Smartdrive Appears To Have No Power

If the module appears to be dead / no power then check the following:-

Is the external mains plug switched on and live?

Are all plugs connected into the Motor Controller?

Phase 4 Only. Check that the product is not "asleep". There is a mode in the motor controller where it can shut down in the event of a transient on the mains. This can be caused by the thermal trip on the pump, i.e. pump block. If this occurs the module will not restart unless the power is turned off at the wall for at least 90 seconds. The module is not damaged and there is no need to replace the motor controller.

Phase 5 Only. The pump is used as part of the power supply if it is not connected Smartdrive will appear dead. Check the pump resistance is 33 ohms. If the pump is open circuit, has the thermal cut out tripped? This should reset within 15 minutes after tripping once the pump has cooled down. If the thermal cut out has tripped, check for a blocked pump.

Check the resistance from Phase & Neutral to Earth. This will identify if either the motor wiring harness or the lid switch harness is shorting to the wrapper.

Check that the resistance of each of the water valves is 15 ohms (phase 1-4), 64 ohms (Phase 5).

Phase 2-4 Only. Check the 15v supply is 11v min, 17v max.

Phase 1 Only. If fitted with an original Phase 1 Motor Controller with a fuse, see WM51.

Replace the Motor Controller, if none of the above faults are found. NB. Ensure product is empty of water when pressure tube is reconnected. If the product is phase 1 to 4, ensure that the console area is dried out before fitting replacement motor controller. Always check the pump resistance before fitting a new Motor Controller.

6.2If Smartdrive Powers Off mid cycle

If there is a power interruption while Smartdrive is performing a wash cycle, Smartdrive will continue when power returns. There are two exceptions.

Phase 4 Only. Check that the product is not "asleep". There is a mode in the motor controller where it can shut down in the event of a transient on the mains. This can be caused by the thermal trip on the pump, i.e. pump block. If this occurs the module will not restart unless the power is turned off at the wall for at least 90 seconds. The module is not damaged and there is no need to replace the motor controller.

Phase 5 Only. The pump is used as part of the power supply, if the thermal trip goes on the pump the product will power off and the cycle will not restart. The thermal cut-out will normally only trip on the pump if there is a pump block.
