The W1903 is equipped with a single Inlet Hose; that must be
connected to a cold water supply.
ƒ
The water pressure must be within 15-145 psi (1-10 bar). If the water
pressure is greater than 145 psi (10 bar), a Pressure Reducer must
be installed. If the water pressure is below 15 psi (1 bar), insufficient
water may be available for a complete fill. The Water Intake Hoses
are equipped with Screen Filters - do not remove these filters.
Note:
For customers requesting a “cold water only connection” on washers
equipped with Dual Inlet Hoses a “Y” adapter (available at most hardware
stores) can be utilized. Both Inlet Hoses (hot and cold) should be
connected to the adapter.
Drain Connection
The appliance is equipped with a 5 ft. (1.5 m) drain hose with a maximum
delivery height of 4ft. (1.2 m) which can be connected as follows:
1. Directly into a sink: hook the hose over the edge of the sink and
secure it firmly (i.e. by tying the hose to the water faucet etc...).
2. To a stand pipe: place the Drain Hose into a 1 1 /2" (38 mm) stand
pipe and secure in place.
3. To a floor drain: The machine is equipped with an Airgap/AntiSiphoning System so that no minimum drain height is required.

There are two Heating Elements mounted between the drum and the
suds container. The Heating Elements are responsible for heating water
to the selected temperature. The Heater Elements are controlled via two
(2) Relays, energized by the Electronic.
The temperature of the water is monitored by the NTC (Negative Thermal
Coefficient) Sensor. As the temperature increases, the resistance
decreases. The resistance value is monitored by the Electronic and is
used to calculate the temperature of the water. Refer to the NTC
Temperature Sensor Operation Table (Table 4-1) below for specific
values.

Water Level Switch
The Water Level Switch monitors the water level inside the drum.
The switch operates by closing specific electrical contacts depending on
the amount of pressure against its internal diaphragm. As the water level
inside the drum increases, the pressure against the switch also increases.
The changes in the switching are monitored by the Electronic and are
used to calculate the exact water level inside the appliance. This design
offers the benefit of keeping the water level consistent, regardless of the
absorption rate of the laundry.
Figure 4-3: Increased in water volume = increased pressure against the Level
Switch.
Note:
On the W1966 and W1986 model clothes washers, the Water Level
Switch is incorporated into the Control Electronic.
During the heating stage of the wash program the Water Level Switch is
used by the Electronic System to ensure water is present before the
heating circuit is activated. In addition the circuit is monitored for any
changes in pressure. Sudden changes in pressure usually indicate an
oversudsing condition. The Electronic System then automatically
performs the necessary adjustments to rectify the condition.
4.7
Water Control System – Intake
During the initial water intake, the Electronic monitors the duration of time
until the Water Level Switch is actuated. This value is used so that certain
wash variables (i.e. wash time, number of rinses) can be controlled during
the program.
If water level 1 is not reached within the programmed “water intake time”
(2 or 4 minutes), the Inlet Valves are closed; the program is cancelled and
the Drain Pump is operated for 90 seconds.

Water Control System – Rinses
During the rinse segment of the program if Level 1 is not reached within
90 seconds of water intake; the rinse duration is extended from 4.5 to 6.5
minutes by the Electronic.
4.9
Inlet Hose(s) Filters
The Water Inlet Hoses are equipped with two filters to protect the Water
Valves. One filter is fitted at the end of the hose (directly at the water
connection). The second filter is fitted within the threaded connections (on
the rear of the washer).
4.10
Inlet Valves
All washers (except the W1903) are equipped with a single ElectroMechanical Water Valve; to control hot water entering the appliance.
The cold water supply to the washer is controlled via a Triple Valve
Assembly. Although the component is physically one item; each valve is
plumbed (and electrically energized) separate to provide water control for
the:
x Pre-Wash
x Main-Wash
x Rinse

Non-Return Valve & Drain Venting
Refer to Figure 4-5 – Non-Return Valve.
During the drain segment of a program the Ball-Seat Valve, (item 1)
closes preventing dirty water from re-entering the Suds Container. Should
the drain connection on site be lower than the water level (within the
appliance) the valve opens to prevent any siphoning of water from the
appliance.

Determining Which Electronic Requires Replacement
(Electronic Test Procedure)
Correct zero crossover point (NND) recognition is required by the
microprocessor to provide a reference point for activating relays and
thyristors. The zero crossover point of the sine wave is the basis for the
time measurement of the microprocessor.
If the Electronic Unit fails to detect the zero crossover of 3 half waves of
the AC power sine wave, a fault is registered and the microprocessor
resets. The current program is cancelled and the LED’s switch off. The
appliance can only be restarted after switching it off and then back on;
and selecting a program.
Because the possibility exists that either Electronic could present the
same type of fault condition; the following procedure ensures the correct
component is diagnosed / replaced.
Service Tip:
In the event the Control Electronic Unit or the Power Electronic Unit
is suspected to be faulty, this procedure must be performed.

Description of Programmable Options
Several programmable options exist for some of the functions in the
Programming Mode.
Warning!
To avoid uncontrolled appliance operation any programmable option
marked “DO NOT CHANGE” (in the descriptions below) should never be
set to any optional values / settings. The data provided is for
informational purposes only.
The following is a description of each function, the appropriate knob
position and a brief explanation of each setting:
RINSE LEVEL (Delicates 105)
The amount of water used for the rinse cycles depends on the amount of
water used during the first fill. At the beginning of the program the water
valve is opened until the first water level is registered. As the laundry
absorbs water, the water level drops. To maintain the original water level

the intake valve is opened again. This continues until the laundry cannot
absorb any more water. The absorbing times and the valve switching
times are parameters being used to establish a provisional loading level.
The amount of water used for the rinse cycles is in conjunction with the
loading level established at the first fill. DO NOT CHANGE.
WATER LEVEL (Delicates 85)
This programs the function performed when the Sensitive option is
selected via the Control Panel. The default setting adds extra water to the
main wash and rinse cycles of a program to thoroughly wash away
detergent scent and allergens. This option is available in the following
programs: Cottons / Permanent Press / Jeans / Dress Shirts and Silk. DO
NOT CHANGE.
WATER INTAKE (Delicates Cold)
The optional setting allows for additional water intake monitoring time. It
will change this time from 60 seconds to 255 seconds. If the Hot Water
Valve (Y12) is opens and the first water level is not registered within 30
seconds, Y12 closes and the Cold Water Valve Y1 opens. If no water
level is registered after 60 seconds the buzzer sounds and the LED Water
intake starts flashing.
PROGRAMMING MODEL NUMBER (Silks)
If an electronic unit needs to be replaced it must be programmed to match
the model number of the appliance. Two models numbers are available in
USA and Canada (W1966 and W1986) the Electronic should be
programmed only to the exact model number it is installed in.
HEATER RATING (Woolens 105)
The washer can be equipped with a variety of Heating Elements. For the
USA and Canada the Heating Elements are 2x1300 Watts and should be
programmed accordingly. DO NOT CHANGE.
SOAK BUTTON (Woolens 85)
This programs the function performed when the Soak option is selected
via the control panel. The default setting allows a soak action to be
performed when the soak button is pressed. The optional setting
programs the button as Gentle Wash instead.
SOAK DURATION (Woolens)
W1966: Programs the soak time duration – applies only if the user selects
the soak option. Default setting is 120 minutes.
W1986: Does not apply - DO NOT CHANGE.

W1900 Series Clothes Washers
Technical Information
COUNTRY SETTING (Jeans)
This does not apply to USA model machines. DO NOT CHANGE.
GENTLE ACTION (Dress Shirts)
With this function activated, gentle action wash rhythms are performed
instead of original set wash rhythms. A reduced drum movement and a
longer rest period while reversing, gently washes lightly soiled fabrics.
The default setting for this function is: Without Always Gentle Action.
SUDS COOLING (Starch)
The temperature of the drain water in the Cottons very hot program can
be reduced with the addition of cool water at the end of the main wash.
This option may be chosen if the drain-line is connected to old plumbing,
plastic drainpipe systems, or is required by code.
MEMORY (Fine Rinse)
The memory feature recalls the selection of a wash options and / or spin
speed selections to a wash program. The next time the program is
selected, the previously chosen options and / or spin speed selections will
also be selected.
RINSE TEMPERATURE (Drain/Spin)
After the main wash, the washer rinses with cold water in up to three rinse
cycles. With the hot water option selected, hot rinses are activated in
Cottons and Minimum Iron Programs. Rinse two is skipped and rinses
one and three are carried out with hot water.
# OF FAULT LED’s (Perma Press Cold)
The Fault Indication LED’s are located at the lower right side on the
control panel. The number of fault LED’s present determines the setting in
this function. Both the USA W1966 and W1986 are equipped with 4
LED’s therefore this value should not be changed. DO NOT CHANGE.
COUNTRY (Perma Press 105)
The wash programs can be customized to suit the needs and habits in
different countries. The default setting is for USA, and should not be
adjusted. DO NOT CHANGE.
LOAD CONTROL (Perma Press 120)
This does not apply to USA model machines. DO NOT CHANGE.
ILLUMINATED PROGRAM SELECTOR SWITCH (Perma Press 140)
When the machine is switched on the Program Selector is illuminated and
remains lit for 5 minutes after the program has finished. If no program is
selected after the machine is switched on, the illumination goes off after
five minutes. When any button is pressed or the Program Selector is used
the switch is illuminated again. This option allows the illumination to be
turned off.

condition (i.e. flooding condition). DO NOT CHANGE.
PROGRAM SWITCH SETTING ALLOCATION (Cottons 105)
This function allows for different programming of the wash cycle times
and cycle positions of the Selector Knob. The default setting is for the
USA Hydromatic IV B1. DO NOT CHANGE.
