Page 4: The Idea
The Idea The objective for Aerosmart was to develop a more fully featured version of the Smartload dryer to match the AquaSmart washer, including an LCD display to offer increased functionality. And to offer Fisher & Paykel’s first multi-lingual dryer. The original Smartload dryer project began on the 11 of October 1998 with a single one-hour meeting. - Page 5 One of the key aspects to this design was to have a single action access to allow the user to access the dryer with minimal effort. This was when the concept of automating the drum door opening arose. Concept models and prototypes of the initial Smartload concept were tested and evaluated by users.

Page 6: Special Features
Special Features Unique top access: Superior ergonomics designed for easy loading and unloading. The wide mouth opening makes transferring clothes from the washer to the dryer effortless, no need to bend! The wide mouth opening provides better visibility into the drum, and easier access to the clean clothes. Reverse Action Tumbling: AeroSmart reverses it’s tumbling action every 4 minutes. -
Page 7: Frequently Asked Questions
Frequently asked Questions Why does AeroSmart Stop and Start all the time? The AeroSmart dryer has Reverse Action Tumbling. It tumbles in one direction for 4 minutes then stops, and tumbles in the opposite direction for 40 seconds. This reduces tangling, roping and wrinkling and increases drying performance by giving you more even drying. - Page 8 What happens if I forget to empty the Lint Bucket? If you don’t empty a full lint bucket, drying times will increase. An empty lint bucket also ensures your clothes will remain lint-free and your dryer will operate at maximum efficiency.

Page 12: The Aerosmart Advantage - Key Claims
The AeroSmart Advantage – Key Claims… Smartest Loader: Utilizing SmartLoad technology – the world’s first Top-Loading, large capacity dryer. The most easily accessible dryer available. Largest Visible Capacity: AeroSmart has easy drum access and is capable of drying a 17½lb (8kg) dry load. -
Page 13: Aerosmart Difference
AeroSmart Difference What makes this dryer so different? Top Loading Dryer The SmartLoad system is the first top-loading large capacity dryer. The obvious benefit of this is that it’s ergonomically superior. The difference with our AeroSmart drying system is that you don’t need to squat down and reach into the back like you do with a conventional dryer. - Page 14 Reverse Action Tumbling We have been using Reverse Action Tumbling successfully in our Australasian dryers for over 30 years. By applying this technique to the AeroSmart dryer we are able to gain significant benefits for the consumer. Benefits of reverse action tumbling include: •...

Page 15: The Theory Of Drying Clothes
The Theory of Drying Clothes An electric heater or a gas burner replaces the sun’s heat. This provides the heat source. A fan provides the wind or airflow over the clothes. How does a dryer work? It is passed over It then enters the Ambient air is an electric... -
Page 16: Drying Stages
Drying Stages Moisture Time Warm Up: Clothes are being warmed up from their ambient conditions. This period is usually short in duration (up to 25 minutes for large loads). Steady State: This is where the bulk of the drying is performed. Post Critical Moisture Content: All moisture on the outside of the fabric has been removed. -
Page 17: How Does Aerosmart Dry Clothes
How Does AeroSmart Dry Clothes? Auto Sensing The Principle… When wet or damp clothes are loaded into a dryer they are partially saturated with water, which is a relatively good conductor of electricity. In the AeroSmart Dryer we use Sensor Bars to measure the conductivity. When moisture in the clothes touches across the Sensor Bars (located beneath the lint bucket) their conductivity is measured. -
Page 18: Dryness Levels
Dryness Levels There are 5 dryness levels the user can select. The setting the user selects determines what moisture content the AeroSmart dryer will aim to reach. The table below shows the different moisture contents for the different cycles and dryness levels. Note: Because of the characteristics of delicate fabrics they are perceived damp when the total % moisture content is less than other fabric types, this is because much of the moisture left is on the surface of the fabric. -
Page 19: Drying Cycles Explained
Drying Cycles Explained The cycles in the Aerosmart dryer have been designed to complement those on the Aquasmart washer. This provides continuity for the consumer, enabling them to use the same cycle for their load in both the washer and the dryer. The way in which items are dried is dependent upon the type of fabric type that is selected. -
Page 20: Testing
Testing A wide range of testing has been conducted during the development of the AeroSmart Dryer. Testing has included: Cycle Development: Cycles have been developed using a wide variety of clothes loads. The loads were weighed before and after drying. But more importantly each garment was felt for dryness just as a user would. - Page 21 Ergonomics and Ease of Use During our testing we have experienced first hand the ergonomic advantages of the AeroSmart dryer. We have bent, crouched, and stretched our way into three traditional large capacity, front access dryers and found that the benefits of improved access are immediately apparent to the user.

Page 23: Aerosmart
AeroSmart’s Innovative Lint Removal System Traditional methods of lint capture and disposal can be very messy and inconvenient. Lint found in dryer filters can be made up of a number of components – dust (skin particles), small broken fibres and fabric fluff, pet hair and dust mite remains. Traditional Large Capacity Front Access Models AeroSmart... - Page 24 It was clear to us when we used these lint removal systems that the AeroSmart dryer provides clear advantages over its competitors for consumers. When released into the air and subsequently inhaled, the particles that make up lint can be a serious irritation for allergy suffers. The AeroSmart bulk lint collection system minimizes the amount of lint particles released into the air by automatically scraping lint off the filter and depositing it into the lint bucket.

Page 25: Wrinkling
Wrinkling What did we test for? To evaluate the degree of item wrinkling caused by the action of the dryers. Why? Ironing is a chore. The more wrinkled your clothes are, the harder and longer this tedious job becomes. One of the benefits of using a dryer should be fewer wrinkles. -
Page 26: Tangling
Tangling What did we test for? To evaluate the degree of clothes tangling caused by the action of the Regular/Normal cycle. Why? Less tangling and twisting of items means improved clothes care. This generally means that items require less ironing and are less susceptible to distortion of shape. How did we test for tangling? We rinsed and spun long sleeved business shirts in an EcoSmart washer. - Page 27 ‘Twist and Shout’ Competitor Dryers AeroSmart...

Page 28: Evenness Of Drying
Evenness of Drying What did we test for? To evaluate how evenly each dryer was able to dry a load of laundry. Why? A good dryer dries the clothes evenly. Final Moisture content indicates average dryness but this can mean that some parts of the garment are over-dry whilst other parts are damp. - Page 29 No dampness One very small patch of dampness...

Page 35: Heat Vs Clothes Care
Heat vs Clothes Care Delicates What did we test for? The amount of heat garments were exposed to during the Delicate cycle. Why? Delicate clothes can often be damaged when exposed to high temperatures. It is recommended that clothing temperature does not exceed 140°F (60°C). How did we test how well each dryer cared for delicate items? We looked specifically at the amount of heat garments were exposed to during the Delicate cycle by placing temperature sensitive “thermolabels”... -
Page 36: Permanent Press Care
Permanent Press Care What did we test for? We tested how well each dryer was able to dry a load of laundry using the Permanent Press cycle. Why test? The Permanent Press cycle is used for clothes that traditionally require ironing. A good Permanent Press cycle results in clothes that are not only dry, but also require little or no ironing. -
Page 37: Speed Vs Clothes Care
Few wrinkles from the AeroSmart™ dryer The AeroSmart dryer Wrinkle Free option is automatically selected for the Permanent Press cycle. The only other dryer where this is the case is the Kenmore Elite Electric. The GE Harmony Gas extended tumble option will operate only if selected and provides only 20 minutes of no heat tumbling. - Page 38 What we found: Average Cycle AeroSmart Maytag AeroSmart Kenmore Time (mins) Harmony Neptune Electric Elite Electric 3lb Regular 6.6lb Regular 3 lb Load With this size load the cycle times are reasonably similar. The Kenmore Elite Electric was the quickest, but failed to adequately dry the load.
- Page 39 The AeroSmart cycle dries at a safe clothes care temperature and uses less energy than its competitors - 29% less than GE Harmony and 21% less than the Maytag Neptune. The benefit of drying at lower temperature is that the dryer is less likely to damage heat sensitive items that may be in the mixed load.

Page 41: Electronic Control
Electronic Control There are three separate electronic controls: the motor control module, the sensor module and the display module. The motor control module receives commands from the sensor module for Sensor Module Display Module operating the heat source and controlling the motor’s speed and direction. -
Page 42: Drum Parts
Drum Parts Drum Inlet End: allows inlet air to pass through, this is how air enters the drum. It also houses the inlet central bearing assembly, about which the drum rotates. Drum End Outlet: provides the route for air to exit the drum as well as securing the lint filter. -
Page 43: Drum Control
Drum Control The drum is rotated by a belt and pulley system to a three-phase induction motor, this is controlled by the Motor Control Module. When tumble drying, the drum is tumbled at 47 rpm and at 5 rpm during opening and closing, other speeds are used as required. -

Page 45: Drum Opening And Closing
Drum Opening and Closing How does AeroSmart™ open the drum door? Once the position of the drum is known (Refer to Drum Control page 47) the door opening sequence can begin. Firstly the drum slows down to the drum opening speed (approximately 5rpm). The grabber door is then lowered down against the drum wrapper by the actuator. - Page 46 The dryer electronics can determine whether the drum has reached the correct position by way of the optical sensor attached to the Sensor board, which uses the dimples on the drum end outlet to determine the drum position. How does AeroSmart™ close the drum door? To close the drum door the drum rotates in the closing direction while the drum door is held stationary by the grabber door.

Page 47: Airflow
Airflow An intake grill at the bottom rear of the cabinet provides an entry point for airflow. Additional air is drawn in at the front of the cabinet under the front panel. Rear Exhaust Air Intake Grill Vent Lower Rear Cabinet Panel A fan on the exhaust side of the drum draws the air over the heating elements/gas burner located in a combustion chamber, through an inlet duct and into the drum. -
Page 48: Lint Removal System
Lint Removal System Lint laden air passes through the small holes in the outlet end of the drum. (The small holes around the lint bucket). The lint removal system is directly behind these holes. As this air moves through the holes it is forced through the lint filter, the fan then sucks the air down through the duct and out the back of the dryer. -
Page 49: Heat
Heat Heat is supplied either by a gas burner or electric elements. Electric Elements In the electric heater models, the heater housing is fitted with two elements that supply about 5kW of heat when both are on. There is a 3.6kW and a 1.4kW element that are used at various times depending on the cycle chosen and the drum/fan direction. -
Page 50: Gas Burner
Gas Burner For the gas model, a gas burner is used to provide the heat. This is turned on for lower duty times for the Permanent Press and Delicate cycles, to apply similar heating as the electric model. The heater is only switched on when the drum is up to speed. The gas heater has a Venturi type gas burner system. - Page 51 The thermostats operate in the same way as the electric elements, although there is one Auto Reset Thermostat and one Manual Thermostat that operates at 293˚F (145˚C). Inside the combustion chamber is a steel plate. This allows cool air to flow between the flame and the top of the combustion chamber, which keeps the outside surface of the chamber cool.
-
Page 52: Fan
The fan moves the air through the heater, drum and exhaust ducting. It is a centrifugal fan, which produces relatively high flow for its size and speed. The fan is mounted onto the motor shaft. The key benefit of our system is that we are able to run the fan faster than conventional machines (we can run at 2300rpm whereas they can only run at ~1700rpm). -
Page 53: Motor
Motor Definition of the motor: The AeroSmart™ motor is a 250W four pole three-phase motor with a cast aluminium end shield construction. It has the same torque in forward and reverse rotations. What does the motor do? It powers the fan and rotates the drum (via the drive-belt). -
Page 54: Dryer Construction

Page 56: Topdeck
Topdeck The topdeck has similar styling to the washer topdeck. It has been specifically designed to give a wide mouth opening to provide easy access into the drum as well as to improve viewing capacity. It also has two plastic brackets on the underside of the topdeck to help provide strength and rigidity to ensure it keeps its shape and doesn’t flex. -
Page 57: Lint Bucket
Lint Bucket White ABS The lint bucket is made from 2 parts. The lower part is clear polycarbonate, to allow the user Clear to see the lint and how full the bucket is. Polycarbonate The handle is made from ABS. It is shaped so it is easy to hold but doesn’t protrude too far into the drum. -
Page 58: Chassis
Chassis Panel Outlet Side Chassis The chassis panels are made from galvanised steel and are a major structural component of the chassis Chassis assembly. There is a panel on each end of the drum. Panel Inlet The chassis panel on the inlet side (the panel on the Side right) holds the duct inlet assembly. -
Page 59: Products
Products In Dryer Dry-Cleaning Products Dryel and similar in dryer Dry-Cleaning products. Dryel is an in-home dry-cleaning product for use in domestic dryers in America, produced by Procter & Gamble. There are a number of other brands of this type of product on the market. - Page 60 Findings In order to follow the manufacturer’s instructions as closely as possible, we recommend using a Easy Iron or Casual (medium heat) cycle, set on 40 minute Time Dry instead of the manufacturer’s recommended 30 minutes. If a user accidentally uses 40 minute/high heat cycle, it did not appear that this would have any adverse effects on the Dryel bag.
-
Page 61: Fabric Softener Sheets
Fabric Softener Sheets A Fabric Softener Sheet can be placed in the dryer at the start of the drying cycle. They are useful for reducing static cling as well as acting as a fabric softener. Static cling happens when clothing continuously rubs together within the dryer. Within this dry environment, friction generates static electricity, which in turn, creates an attraction between various garments. -
Page 62: Servicing
Servicing How does the Dryer Rock Out? The dryer has been designed so all the internals and chassis are separate from the cabinet/wrapper. This makes it easier to service. If possible unplug the dryer from the main power supply, or disconnect the circuit breaker. - Page 63 Faults Codes If a fault occurs that prevents correct operation of the dryer, the dryer will stop the machine will beep and a fault code is displayed. (The same sound AeroSmart™ makes at the end of the cycle). Pressing the Power button stops the beeps and leaves the fault code displayed, this is to help the service technician diagnose the problem.
- Page 64 Fault Code 3 Reason: Drum is stalled; unable to move. Background: A command is sent to the motor control to move the drum. The motor control uses the tachometer signal passed down from the sensor board to monitor the drum movement, and if this signal is not present the “stall”...
- Page 65 Fault Code 8 Reason: Exhaust sensor measures over temperature (185 F, 85 Background: The exhaust duct from the drum is monitored so that the temperature of the clothes load can be controlled, particularly as the load becomes dry. The highest temperature allowed for the hottest denim cycle is 150 C), at which time the element or gas is switched off.
- Page 66 Fault Code 11 Reason: Lid lock open circuit. Background: After the lid is locked, the motor control module checks on the integrity of the circuit by checking that current is still flowing, and if not, assumes the circuit has gone open circuit and flags this fault. Remedy: Check the lid lock harness and coil.
- Page 67 Fault Code 20 Reason: Door actuator stalled. Background: A small electric motor is used, via a gearbox, to open and close the drum door. The sensor module monitors the movement of the motor, and if it detects the actuator as being tight and unable to move sufficiently, it will display this fault.
- Page 68 Remedy: Check continuity of the door grabber circuit. Replace component as necessary. Replace the actuator mechanism. Fault Code 29 Reason Brown-out data retrieval error. Background: When the power is switched on to the appliance, the motor control module retrieves operating parameters from when it lost power. A check is made on the parameters, and if an error is detected it disregards the data and loads up default values instead, and will initiate the motor control module in the “idle”...

Page 69: User Warnings
User Warnings For a user warning, the dryer will either pause, or “limp on”, and flash an L.E.D at the same time as sounding a user warning (the same sound AeroSmart™ makes when it is plugged into the wall). User Warning 6 Reason: The door is unable to close due to either clothes catching or an excessive closing load. -
