Introduction

Introduction
The Wascomat Junior, Super Junior, Senior and Giant models washer/
extractors have been developed to cover the heavy duty and various size
requirements of coin laundries, apartment houses, hotels, motels, nursing
homes, hospitals, professional laundries, restaurants, schools, colleges and
all on-premises laundries where high quality automatic washing and quick
formula variation are required.

The W models offer four pre-set wash programs Hot, Warm, Cold and
Delicate which can be selected by turning the rotary program selector on
the front panel. These programs are designed to suit a variety of fabrics
and offer different water temperature programs. The machine is designed
for connection to hot and cold water supplies.
All parts of the machine which come into contact with the items being
washed are made of heavy gauge surgical stainless steel, ensuring long life
and lasting beauty, as well as full protection for no-iron fabrics. All electrical
components are made accessible for servicing by simply removing the top
panel.
This manual contains a technical description of the Wascomat W75, W105,
W125 and W185 model machines and instructions for their installation,
operation and maintenance. Together with the wiring diagram which
accompanies each individual machine it should be kept in a safe place for

The machines are designed to be bolted in
position to a concrete floor or specially prepared
concrete foundation. A template showing the size
of the foundation and positioning of the foundation bolts can be provided by Wascomat.
For installation on an existing concrete floor, the
floor must be at least 8" thick and of good quality.
If the floor does not meet these requirements,
then a 6-8" high concrete foundation should be
made. A prefabricated steel base is available for
mounting of machines without an additional
foundation.
Follow the instructions below when making a
concrete foundation:
1. Decide where to place the machine and
consider maintenance requirements, i.e.
determine a suitable distance from the rear of
the foundation to the wall, and the distance
from the foundation to the nearest side wall.
The distance should be at least 16 and 12
inches, respectively.
2. Break up the floor to a depth of 3 inches,
making sure that the sides of the hole slope
inwards - the bottom of the hole should be 5
inches longer than the upper length.
3. Wet the hole well. Brush the bottom and sides
with cement grout.
4. Prepare a casing and fill with 3,000 PSI min.
concrete to form a pad. Make sure the foundation is level.
5. Use the template to position the foundation
bolts correctly - bolts are to extend 1 1/2"
above concrete.
NOTE: A prefabricated steel frame, designed
to be placed in the concrete instead of the
individual mounting bolts, is available from
Wascomat.

• Check that the machine is level front-to-rear
and side-to-side and standing firmly on the
four (W75, W105) or six (W125 W185) supporting points. Spacing washers must be
mounted if one or more of these points is not
resting against the floor/foundation.
• Place flat washers over the foundation bolts
and secure the machine in position by tightening the self-locking nuts. See illustration
below.
• Check and tighten the nuts every week for the
first month to compensate for any setting of
the foundation.

Installation
Electrical installation

All electrical installations are to be carried
out by licenced personnel.

Fig.

Although the machines are equipped with
thermal overloads in the motor windings a
separate three-phase common-trip circuit breaker
must be installed for all three-phase machines.
For proper overcurrent protection, check the data
plate at the rear of the machine. Also consult
local electrical code for special requirements.

Fig.
9

Use inverse-time circuit breaker only.
Connect L1, L2, L3 and ground wires according
to the markings of the terminal block at the upper
left rear corner of the machine. The cable is to
hang in a large loose loop, supported by the clip
of the terminal block.

1830

After installation, do the following for 3-phase
machines:
Fig.
10

Fig.
10

Check the incoming power for a high voltage or
"stinger" leg. This will usually measure higher
than 150 Volts to ground. If present, connect that
line to L2 on the terminal block.
For 3-phase machines start the machine and
check that the drum rotates in the ccw direction
during extraction, when seen from the front. If the
drum rotates in the wrong direction interchange
lines L1 and L3 at the power connection terminals.

Incoming water lines should not require nonreturn or back-suction valves, as the machine is
already equipped with backflow prevention. Shutoff valves must be provided on all incoming water
lines.
• Water inlets are labelled for hot and cold
water connection.
• Before connecting the water hoses flush the
water lines thoroughly and check that the filter
at the machine inlet is fitted correctly. This is
essential since dirt and grit in the water lines
may clog the inlet valve filter screens and/or
drain pilot valve, causing the machine to fill
very slowly or the drain valve not to operate
properly.

1832

W 75, W105, W125

• Connect the water supply to the machine with
3/4" reinforced rubber hosing not to exceed 6
ft in length. Hang the hosing in a large loop.
Do not use rigid piping.

W 185

• Never force a hose onto the threads or you
may cause cross-threading and leaks. If this
occurs, place the threaded portion of the hose
over the valve threads and push forward
firmly, to catch the next thread. Then tighten.

The drain hose may be connected to a 2" to 3"
T-connection coming out of your main drain line,
which is typically four inches diameter, or the
washer may dump into a trough which slopes to
a drain, or directly into a floor drain as shown in
the illustration. Check local codes for required
installation procedure.
The drain hose must not have sharp bends and
must slope from the machine to assure proper
drainage. If the machine(s) drain into an open
trough the trough should have a slope of 1/8"1/4" per foot towards the main drain.
Note:
To simplify installation, Wascomat has made
available the following hose kits:
For W75, W105 and W125

Door
Fig.
32

The door consists of: a door skirt (1), door (2),
glass (3) and gasket (4). The frame skirt and
door frame are both made of enameled aluminium. The skirt is bolted directly to the outer
shell of the washing machine.The door hinges
are fastened on the outside of the skirt and the
door lock (5) is attached to the inside. The heathardened glass is mounted in the door using a
special rubber seal which also acts as a gasket
between the door and the washing machine’s
outer shell when the door is closed.

NOTE
Do not attempt to repair a faulty
door lock. The individual
components are not available.
Always replace the old unit with
a new one to assure proper
operation of the door safety
interlock.
32

Door lock
Fig.
33

The door lock consists of a circuit board (1) with
a connector. Mounted on the board are the lock
plate (2), against which the locking bolt turns to
lock the door, and a microswitch (3) which closes
when the locking bolt has locked the door.

4
2

There is also a locking device on the circuit board
which acts to lock the locking bolt in place when
the machine starts up.
The locking device consists of a double-acting
solenoid (4), a delay unit (5) and the locking
device itself (6) which operates sideways in
blocking the locking bolt with a stud. The locking
device can be affected by both the solenoid and
the delay unit.

The lock operates as follows:
• When the door is shut and the locking bolt
moved to the lock position, the micro switch
will indicate that the door is closed.
• When the machine is started, the solenoid
actuates the locking device, blocking the door
lock. The locking device signals the delay unit,
closing a switch in the unit. The washing
machine motor will start and water enter the
machine only after the delay unit receives the
information that the door is locked. The bimetallic spring in the delay unit is warmed up
at the beginning of the program.
• Once the washing machine stops at the end of
a cycle, the solenoid pulls back the locking
stud and allows the door to open. The delay
unit is spring-mounted in the locking device
and is also pulled back by the solenoid, which
operates for about two minutes to allow the bimetallic spring to cool down enough not to
lock the door again.

• If current should disappear during a cycle, the
delay unit will keep the door locked for about
two minutes, ensuring that the wash water can
drain out (The drain valve opens automatically
when current is lost).

Control unit
Fig.

The wash cycle timer (1) and rotary program selector switch (2) are
mounted just behind the control panel.
The relays (3) and level controls (4) are located at the top of the machine,
easily accessible for service, as are the motor capacitors (5) on 1-phase
models.
Electrical connections to the machine are made by quick-disconnect plugs.

1192

Mechanical and electrical design
Relays
Fig.
35

The W-series models employ either two
(W75, 105) or three (W125, 185) relays to
energize the windings of the wash/extract motor.
The relays control:
• The reversing action of the motor at wash
speed.
• The action of the motor at extraction speed.

Construction
Fig.
36

The body of the relay holding the stationary
contacts is made of current-resistant plastic.
A solenoid and a contact bank hold the moving
contacts. The contacts are spring-loaded to
assure the correct contact pressure.
The relay is constructed for continous operation,
whether mounted horizontally or vertically.
Screw-type terminals provide perfect connections
even when one or two wires have different diameters.

Operation
When the solenoid is energized, the two halves
of the magnet core are drawn together, pulling
down the moving contacts, thus making or
breaking the circuit. When the current cuts out,
springs force the contact bank into its original
position, thus closing or opening the circuits.

1197

Trouble shooting
If the relay fails to operate despite power to the
coil, turn off the power and check the solenoid by
measuring the resistance across the terminals
(1).
If the relay hums when power is applied, this
indicates either a break in the insulator holding
the moving contacts at the axle where it holds the
top half of core (3), or a rusty core (4), which can
be cleaned.
Make sure that the moving contact assembly
moves freely. Always replace burnt or pitted
contacts (2) ... do not reuse contacts.

Mechanical and electrical design

Water level controls
Fig.
37

One pressure switch is used to control the correct water levels during
various cycles of the washing program.

Adjustment
All pressure switches are factory-calibrated to meet specific requirements.
The trip level for any one pressure switch can be changed only within
narrow limits because each trip range requires a different set of springs.
Call Wascomat's Service Department at 516-371-0700 before attempting to
adjust the level control.

Water level
As a guide for checking the level control for proper functioning, the normal
level should be approximately at the bottom of the door glass. It is primarily
the reverse-wash mechanical action of the washer which gets clothes
clean, not the level of water or amount of detergent. The water levels are
set at the factory to get a full load clean without wasting a drop of water, to
save you money and protect the environment.

1158

Mechanical and electrical design
Drive motor

Description in general
Fig.
38
Fig.
39

The motor is mounted on an axle with rubber
dampeners.
The V-belt is tightened by turning the motor on
the axle and locking it in place using the
tensioner on the rear side of the motor. The
motor and tensioner have vibration and noise
dampening rubber suspensions.

Construction in general
The motor consists of stator, rotor and endshields with ball-bearings. The stator and the
rotor consist of plates, insulated from each other
and welded together. The stator is provided with
slots in which the 2-pole and 18-pole windings
are wound. The windings are impregnated with a
temperature-resistant sound-insulating resin
varnish according to class B. The end-shields are
die-cast. The ball bearings are permanently
lubricated.

Construction of single-phase motor
Single-phase motors have an 18-pole winding
(wash-speed) the same as three-phase motors,
using a continuously connected capacitor, while
the 2-pole winding (extract-speed) is a specially
designed winding with both a continuously
connected capacitor and a starting capacitor.

1153

Function of 3-phase motor
When the stator winding is charged, a magnetic
field will occur, which in turn will rotate the rotor
at a fixed RPM depending upon the number of
poles in the winding. The 18-pole winding gives
the wash speed and the 2-pole winding the
extract-speed. When operating with load, the
speed deviates slightly from the synchronous
(no-load) speed. This difference is called the slip
and is usually expressed as a percentage of the
syncronous speed. The motors will work satisfactorily at nominal voltage +10%-15%.

Function of single-phase motor
When the stator winding is charged without a
capacitor, two counteracting magnetic fields are
created. When a capacitor is connected, it will
displace one of the two magnetic fields adding it
to the other, creating a torque turning the rotor in
a specific direction. The RPM is the same as for
the 3-phase motor.

Motor overload protector
The motor is equipped with two self-resetting,
thermal overload protectors, situated one in each
of the windings of the stator. The protectors are
connected in series and will trip at a temperature
of 120°C (248°F) (3-phase) or 130°C (266°F)
(single phase). In the event the protectors fail
but the motor remains otherwise undamaged, an
overload protector may be mounted in the control
unit of the machine. Before making such installation check to ascertain that the windings are not
damaged. A burned out motor can be re-wound.

Inlet valves for W75, W105, W125
and detergent valve for W185

Construction
Fig.
43

Each valve has a single-inlet with either one, two
or three outlets, each with its own solenoid coil.
The body is made of heat-resistant polyamid
plastic and the solenoids encased in water-tight
plastic.
A filter screen on the inlet side prevents dirt from
entering the valve. Flow restrictors can be placed
at either the inlet or any of the outlets.

Operation
Fig.
44

When the solenoid is energized, the springloaded plunger is drawn up and the pilot valve in
the center of the diaphragm open. Because of
the difference in diameter between the pilot valve
opening and the ventilating hole in the diaphragm, the pressure above the diaphragm drops
to a point where the admission pressure below
the diaphragm can lift the diaphragm, thus
opening the valve.
When the current to the solenoid is cut off, the
plunger spring will press the plunger against the
pilot opening of the diaphragm. The pressure
above the diaphragm then rises to correspond to
the water inlet pressure and the pressure of the
spring will close the valve.

It is therefore advisable to dismantle and clean
the valve at certain regular intervals. The frequency depends on operating conditions and the
level of contamination in the water.

Trouble shooting
If the valve does not open

• Check that power is supplied to the coil.
• Check the coil with an instrument to determine
whether there is a break or a short circuit.
• Dismantle the valve (see below) and check
the openings in the valve diaphragm.
• Check the inlet strainer and clean as required.

1186

• Undo the coil and clean the surfaces of the
magnetic core.

If the valve does not close
• Check that the coil is not live. The valve is
normally closed when the magnet is not
energised.
• Check the return spring.
• Check the diaphragm (pilot pressure opening).

Clean out
At water temperatures of more than 60°C/140°F,
the lime deposits are heavily increased. This can
cause function problems due to blocking up the
equalizing orifice of the valve.
Fig.
50
Fig.
51

The fault can be eliminated by cleaning the
equalizing orifice (marked A).
If there are much deposits the orifice can be
changed from 0.5 mm to 0.8 mm. The screwhead
of the orifice is marked with 1 ring for the size of
0.5 mm and 2 rings for the size of 0.8 mm.
Clean the orifice as follows:

0368

1. Shut off the main supply.
2. Unscrew the orifice.
Fig.
52

3. Clean the hole in the orifice carefully with a
pin or similar not thicker than 0.5 resp.
0.8 mm.
4. Mount the orifice, be careful with sealing and
tighten.
5. Open the main supply.

Drain valve

Description
Fig.
53

The drain valve is operated by using the pressure
in the cold water intake. A tube (1) is connected
between the cold water intake and a solenoid
valve (2). When the solenoid valve is activated, it
opens and allows water to flow into the feeder
tube (3).The water presses up a piston (4), which
uses the pressure lid (5) to close the drain valve
rubber membrane. When the solenoid valve cuts
out, the water presure push the piston back,
allowing the water to pass the solenoid valve and
drain out via the return tube (7).

Trouble shooting
If the drain valve doesn’t close:
• Check that the solenoid valve (2) receives
electricity.
• Check that the solenoid valve and the tubes
are clear by:
- removing the drain hose (3).
- Check that water exits the hose when the
valve is activated.

• Check that the diaphragm (8) is undamaged.
If the drain valve doesn’t open:
• Check that the return tube (7) is open.
• Check that the piston (4) doesn’t seize.

Soap supply box
Fig.
54

The three-compartment soap supply box is located at the top of the
machine. Viewed from the front, the compartments are marked with figures
1, 2 and 3 and are used as follows:
Compartment 1
This compartment is used for adding powder detergent at the beginning of
the Prewash cycle. Powders may be loaded immediately; for liquids, wait
until the compartment flushes with water.
Compartment 2
This compartment is used for adding detergent at the beginning of the
Wash cycle. If liquid bleach is used, it is added to this compartment when
the compartment is flushed with water.
The insert is used to help prevent oversudsing.
Compartment 3
This compartment is used for liquid fabric softener, which is siphoned into
the drum at the start of the third rinse. Liquid softener may be added at the
beginning of the cycle or during the final rinse.

1182

Maintenance

Preventive maintenance has been reduced to a
minimum by the careful design of reliable components and material.
However, the following measures should be
taken at regular intervals and in proportion to the
hours of service.

IMPORTANT!
Make certain that all electrical power to
the machine is shut off before removing
top or rear panels.

Daily
• Check the door lock and interlock before
starting operations.
• The soap supply box should be cleaned at the
end of each working day as follows:

1833

- Use a spatula to scrape loose any detergent which may have stuck on the inside of
the dispenser.
- Flush the loosened detergent with warm
water.
- Wipe dry and leave lid open.
Fig.
55

• Check that the drain valve does not leak and
that it opens properly.
• Check that the door does not leak. Clean
residual detergent and foreign matter from the
door gasket.
• Wipe the outside of the machine.
• When the machine is not in use, leave door
slightly open to allow moisture to evaporate.

Weekly
• Remove the hose from the drain connection
and clean the inside of the drain valve.

Every three months
Fig.
56

• Remove the rear panel of the machine and
check that the V-belt of the wash motor is
undamaged and correctly tensioned.
• Check that all tubing, piping and connections
are free from leaks.
• Wipe and clean the inside of the machine,
making sure that the control components are
protected from moisture and dirt during the
cleaning operation.

Trouble shooting
The purpose of the trouble-shooting guide is to facilitate the location and
correction of the most common machine problems.
Before the top panel is removed, power to the machine must be switched
off at the main source or at the separete circuit breaker.
At each trouble-shooting attempt, the plug in connectors on the control
panel should be moved in and out in order to eliminate improper contact
due to faulty connection.
Please note that this guide does not include all possibilities, but only those
most likely to cause the symtoms listed.
In trouble-shooting electrical problems, always make certain to have the
proper electrical schematic or wiring diagram at hand. Test for power using
a V-O-M or similiar meter on the AC voltage scale. Test for continuity with
all electrical power off.

Trouble shooting

If the machine does not start
Fig.
57

A Check the circuit breaker in the electrical
power line to the machine.
B Check the door safety switch and door lock.
C Check the glass cartridge fuses.
D Check for loose wires at the incoming power
terminal block.

If water does not drain
Fig.
58

A Check the drain valve and drain solenoid for
proper operation.
B Disconnect the drain hose connected to the
drain line. If a full flow of water comes out, the
problem is in the main waste line. If water flow
is slow, the problem is the accumulation of
foreign materials between the drain valve and
shell outlet of machine. Clean the valve body
of any foreign objects found.
