INSTALLATION REQUIREMENTS

DRAINAGE

A vertical standpipe with an internal diameter of 1-1/2”
(3.8 cm) is required. The standpipe height above the
floor must be:
Minimum height: 36” (91,4 cm)
Maximum height: 96” (243,8 cm)
Insert the drain hose into the standpipe and secure it
with the cable tie located inside the accessories bag.
The standpipe must be open to the atmosphere (there
must be an air gap around the drain hose).
If you need to extend the lenght of the drain hose to

reach
your standpipe, please contact your local parts store to
purchase the recommended drain hose extension for

your washer.

Cable tie

WATER SUPPLY REQUIREMENTS

Hot and cold water faucets MUST be installed within 42”(107 cm) of your washer’s water inlet. The
faucets MUST be 3/4” (1.9 cm) garden hose-type so inlet hoses can be connected.

Water pressure MUST be between 10 and 100 pounds per square inch.
Your water department can advise you of your water pressure.
The hot water temperature should be set to deliver water at 120° to 140°F (48° to 60°C).

Washer Warranty

Flow Logic automatic drawer dispenser.

Your washer is equipped with an automatic dispensing system, comprised of a drawer with 3
compartments:

Bleach Detergent Softener

Liquid bleach

Pour liquid bleach into the designated compartment with­out filling beyond the mark.

Check clothing care labels for special instructions. Use
less for smaller loads.

Do not dilute bleach. Bleach will be added automatically
diluted to avoid direct contact with the clothes. Use only
this compartment, do not add bleach directly onto clothes.

IMPORTANT:

To avoid any potential leftover bleach mixture being dis­pensed in a subsequent cycle, it is strongly recommended
to verify that the bleach compartment of the dispenser is
free of any leftover bleach and water mixture. If there is
some leftover bleach mixture, please empty the contents
to avoid any damage to clothes that cannot tolerate
bleach

.

Detergent

Add the amount of powder or liquid low suds detergent in the compartment, as recommended by the manufacturer and according to the size of the
load. You should not put the detergent directly on the clothes in the washer.

· For powder detergent: Install the divider in the front position. Put the detergent selection blue wall, that is located at the end of the dispenser, in
the front position

· For liquid detergent: Install the divider in the back position. Put the detergent selection blue wall , that is located at the end of the dispenser, at
the back position.

Place the amount of liquid detergent without exceeding the maximum level indicated.

Fabric Softener

Pour fabric softener into the designated compartment without filling beyond the mark.

Note: in order for the fabric softener to be dispensed you must select the DEEP RINSE option. Please refer to the Options

section of this manual.

INTRODUCTION

TM

HydroSoft
technology provides excellent cleaning. Infusor models are ENERGY STAR® qualified
using only 23 gallons of water per (super) load compared to 48 gallons for a similar
load with a standard machine .

High efficiency (HE) detergent is required with Infusor models. Liquid HE detergents
dissolve faster in water. For best performance, load the machine by adding liquid HE
detergent first. Add the dirtiest clothes around, but not covering, the center of the
Infusor, then add the remaining clothes. Do not load clothes higher than the line
indicated on the balance ring at the top of the wash basket. Insert items as per the
Use and Care. Select proper load size, water temperatures, and rinse options. Use a
fabric softener for better performance

model washers use an InfusorTM, not a traditional agitator. Infusor wash

Washer Tips

Infusor models turn the washer basket at slow speed during fill to allow the fill funnel
to evenly coat the wash load with water and push clothes to the bottom. The lid will be
locked during the fill to evenly wet the clothes. If you wish to add or remove an item,
press the Start/Pause button to pause the washer. The lid will unlock once the basket
has come to a complete stop. This is for your safety.

Infusor models spin at up to 700 RPM. This extracts more water during the spin cycle,
compared to a standard machine, and minimizes drying time. If wrinkling is a concern,
use a lower spin level to shorten the spin duration.

Given that Infusor washers operate differently from standard top-load machines,
consumers may comment on lint, lower water levels, washing differently than
expected, spots on clothing, wrinkling, water temperature, vibrating/shaking, too-wet
clothes, unusual sounds, or loose tub/basket.

Take the time to listen carefully and fully understand the consumer’s specific issue
before proceeding. Address the appropriate issue today to avoid a return service call.

14

UNDERSTAND THE CONSUMER’S ISSUE FIRST

1. Lint
Do not overload the washer. Use the Deep Rinse option, adding more water, to

reduce lint.

2. Not filling or low water level
Infusor models are designed to use less water and are ENERGY STAR® qualified.

During the wash cycle, water may not entirely cover the top of clothes. If Super size
load is selected, the water level will be just at the top of the Infusor.

Check for water supply hoses pushed up tightly against a wall. This condition can
affect the position of the fill funnel so that the water spray isn’t correct during fill. Pull
the washer away from the wall a little to correct.

Water pressure and water flow are critical to washer fill. The washer will not fill to the
proper level with a water pressure less than 20 PSI or with a blocked valve inlet
screen or other flow restriction.

The fill volume on the Small setting is 9 gallons. The water level will measure
approximately 5 inches above the bottom of the basket

..

Note: Measured water levels are approximate and can vary plus or minus 1 inch.

On the Super setting, the fill volume is 14 gallons. The water level will measure
approximately 8 inches above the bottom of the basket. With Super setting, the water
will come up to the top of the Infusor.

15

All models have the PreciseFill Automatic Load Sensing feature. When PreciseFill is
selected, the machine determines fill time by sensing the load size. The Precise Fill
pressure switch minimum level setpoint. The lower level setpoint is attained at
approximately 1 inch of water depth, at which point the washer will start sensing the
load size and determine the optimal amount of water required and corresponding
water level.

Use the Deep Rinse option to add more water during rinse.

3. Washing differently than expected

Load the basket with similar weight items around the sides of the basket.
Overloading the washer can lead to poor cleaning performance.

Check for water supply hoses pushed up tightly against a wall. This can affect the
position of the fill funnel so that water spray isn’t correct during fill. Pull the washer
away from the wall a little to correct.

4. Spots on clothing

Usually caused by too much HE detergent; use less. Use less HE detergent with
softer water. Clothing is cleaned when soapy water bonds to the dirt and is rinsed
away. Too much detergent can generate soapy foam that is difficult to rinse away.
To correct, run a couple of cycles empty with no soap to rinse the machine, and then
run a load with less HE detergent. Use the Deep Rinse option to add more water
during rinse. Check for possible siphoning condition.

5. Wrinkling

Do not overload the washer. Overloading can lead to poor cleaning performance and
increase wrinkling. Infusor models spin faster than standard top-load machines to
extract more water for faster drying and can cause more wrinkling. If wrinkling is a
concern, use the Deep Rinse option to add more water during rinse, and select a
lower spin level for less spin time.

16

6. Water temperature

Energy-star requirements dictate that even on a hot setting, the washer will mix in
some cold water. If the home water supply pipes have a long run, are imbedded in a
concrete slab, and/or the washer is used during the winter months, it may take
longer for the first hot water to reach the washer. Run the hot water at a nearby
faucet to check water supply temperature.

7. Vibrating/shaking

Check for proper levelling. If only an occasional complaint, check for out-of-balance
load.

8. Too-wet clothes

If the final spin leaves clothes too wet, re-arrange the clothes to balance the load,
then run another drain and spin cycle.

9. Loose wash tub/basket

A loose basket is normal when the washer is idle. Infusor models do not use a
mechanical brake to prevent the basket from turning. The basket slows down on its
own and will normally come to a full stop in less than 2 minutes if spinning at full
speed.

arrangement

If load is greater than 17lbs, it bypasses the "load arrange­ment" phase and goes straight to the pre-fill portion.

Washer executes pattern to distribute the clothes previous to
agitation in order to improve wash performance.

Load spins 2 times (CCW-CW), each time injecting cold water for 8
seconds.

• During each spin portion, the motor is successively activated (for
600 ms) and deactivated (for 2 seconds), intermittently spinning the
basket for a total of approx 10 seconds.

• Once the 10 seconds are over, unit goes into a full spin (at 700
RPM) and drain pump is activated for 10 seconds.

•After this, unit slows down to 100RPM.

Fill to Minimum

Water Level

Water and detergent are admitted in this stage
directly into the basket.

• Water fill starts until the minimum water level is
reached.

• Water is at temp selected by consumer, regulated
by ATC thermistor.

19

Wash Cycle Progression (cont.)

Washer agitates to determine if water level (as selected by con-

sumer) is appropriate for actual load size and type of clothes.

•After minimum water level is attained, washer senses if load is
greater than 17lbs (impeller only goes back and forth).

• Basket is spin intermittently by pulses (3 times CCW, then 3 times
CW) and water is injected via the dispenser, dispensing soap.

•If load is less than 17lbs, agitation can start after fill is complete to
desired level.

After load sensing, washer fills to desired level

• Washer fills to level selected by consumer or greater level if load
sensing determines selected load size is not sufficient.

Agitation

Washer agitates according to settings chosen by consumer,
between 14 and 18 minutes.

20

Untangling

Wash Cycle Progression (cont.)

Soft agitation pattern for 3.5 min. in order to detangle and
balance clothes previous to spin.

• Washer agitates at different rate than main wash to set the
clothes in place for spin, for 3.5 minutes.

Drain

Intermedi-

ate Spin

Drain the wash water, until the minimum water level
setting is reached (no agitation).

Intermediate Spin pattern consist of a series of speed
ramps until maximum speed is reached.

• 30 seconds after "minimum"** water level is reached,
washer starts spinning basket doing 5 preliminary ramp ups
to ensure load is properly distributed and safe to bring up to
next spin level.

• The 6th spin level is the last of the Intermediate spin por­tion. If it's able to reach 600 rpm in the predetermined
amount of time, it keeps that speed for a total of 1.5 min­utes.

** the "minimum" water level is actually lower than the
Minimum water level setting. It's approx. 1" of water in
the tub.

21

Wash Cycle Progression (cont.)

Shower rinse is the normal rinse cycle. However, in some
instances the washer will go to a Deep Rinse instead:

•when fabric softener is used and customer has selected the
Deep Rinse option.

•on certain cycles such as Bulky Items.

•if the washer recognizes that a higher water level than the one
selected by the consumer is required to ensure proper opera­tion of the washer.

The shower rinse is a timed fill, with water quantity dependant

Rinse Fill

on the water pressure regulated by water valve.

The number of Shower Rinses is determined by the water level
selected by the consumer and the actual water level as deter­mined by the washer.

• If water level is Maximum or higher, washer does 3 rinse
blocks.

• If water level is High or lower, washer does 2 rinse blocks.

22

Shower Rinse Progression

17- Once the base is removed, release
the wire harness plastic retainer.

Transmission removal is now complete

The transmission is a complete sub-assembly
including the base as shown in the picture.

34

ATC Thermistor

The ATC controls the water temperature selected by the customer.

If the ATC thermistor fails or harness is broken, the washer will still operate.

The control will open just the cold water valve.

At room temperature ( 20ºC) , the resistance should be approximately ~11KΩ.

Resistance goes down as temperature goes up.

NOTE: The ATC is activated Only during main fill.

35

Water valves & Drain Pump

Testing Water valve

• With harness disconnected the resistance

value of any of the 4 water valve coils should
be approximately 1KΏ

• The water valve can also be tested with a

120 Volt test cord.

Testing Drain Pump

• With harness disconnected the resistance value

of the drain pump should be 15Ώ

• The pump can also be tested with a 120 Volt

120 VOLTS APPLIED

With the wax motor energized the

Motor Sensor

The speed sensor in the motor operates on a 10 vdc signal from the control board.
The control board reads the pulses from the motor to determine proper operation.
This signal can not be read with a conventional multi-meter while operating. Besides
diagnostic error code mode – disconnect the sensor harness from the control and
read AC millivolts on the sensor harness while rotating the spin basket CCW.

In wash mode, after the water valve turns off, it is normal for the motor to operate in a
short stroke pattern before the regular agitation cycle begins. The motor will then run
in both clockwise and counter clockwise rotation to provide 180 degrees of agitator
arc.

In the spin/rinse mode, the motor runs only in counter clockwise rotation. At spin
startup it is normal for the motor to pulse a couple of times in each direction – this
assures the shifter gear is set for spin. A clunking noise is normal during this startup
routine. In spin the control will perform two ramp ups in speed to 290 rpm and then
turn the motor off until 0 rpm is reached. The control will then energize the motor for
full spin.

Motor sensor =39 KΏ. (Reverse the polarity from your multimeter you will read infinite.)

Press the START button to begin the wash cycle.

Power is sent to terminal 3, activating the solenoid, turning the green cam 30 deg.

Then locking pin falls in place, closing the circuit at terminal 5, sending a signal to the board that
the lid is locked. This terminates power to terminal 3.

The lock signal from terminal 5 to the board now allows the motor to run..

Note: The board looks for this lock signal with a pulse up to 5 times. If it does not receive this
signal it will show F8. The board will repeat this up to 3 times (with a 30 seconds pause between

How to Enter or Exit to Service Mode

1. Unplug the washer.

2. Turn the Cycles knob to POSITION 6

3. Re-plug the washer pressing Start/Pause

and Options buttons at the same time for

3 seconds. Display will show “LLL”.

Service mode function

1. Once in the service mode, a technician

can test each component by setting a

knob position and pressing the Options

button.

2. Pressing the Start/Pause button pauses

the component test.

3. A technician can suspend any test by

turning the Cycles knob to any position

(except Heavy Duty) or pushing the

Options button.

How to exit to Service mode

1. Turn the Cycles knob to Heavy Duty and

wait for 3 seconds. Washer is ready to run

any wash cycle.

ERROR AND FAULT CODE

Warning and Error Codes A Warning code appears when a failure has been detec-

ted. After displaying a Warning code for 30 seconds, the washer will attempt to resu­me the cycle. If the failure persists, the Warning code will be shown once again. If
the washer is able to resume the cycle on its own, Warning code will disappear from
the display and NO SERVICE IS REQUIRED.

After 3 unsuccessful attempts to resume the cycle, should the washer be unable to
continue an ERROR CODE will be shown. At this point, ONCE AN ERROR CODE
APPEARS, SERVICE IS REQUIRED

1- Lift up the top.

2- Unplug the main connection.

3- Do the test.

You can check the wax motor, drain pump, motor and the speed control. The

readings obtained are resistances (Ώ).

Water (level) Pressure Sensor

Water Pressure Sensor

The sensor operates on low voltage DC which can be read from the control board
connector J6.

The voltage will increase from ~ 0 vdc (empty) to ~ 2.1vdc (full) across terminals
1 & 2, (Beige to Purple) .

Terminals 2 & 3, (Purple to Black), will read the inverse voltage, the voltage will
increase on fill.

Test is performed at the control board with the harness attached.

Empty = 0 vdc

Small = 1.3 vdc

Medium = 1.55 vdc

Extra large = 1.85 vdc

Super = 2.10 vdc

Ps. If the water level is changed when testing, allow 30 to 60 seconds before the
motor stop and water valve is energised.
