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,

Installation

Machine foundation

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 foun-

dation 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 foun-

dation 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.

Mechanical installation

• Place wide steel shims on the concrete foun-

dation over the bolts.

• Lift the machine and lower it in position. Never

use the door or the door handle to lift or lower

the machine.

• 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) sup-

porting 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 tighte-

ning 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.

Electrical installation

All electrical installations are to be carried

out by licenced personnel.

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.

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.

After installation, do the following for 3-phase

machines:

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 termin-

als.

Signals for external supply (non-metered

machines).

At the rear of the machine, next to the incoming

lower terminal block, there is another terminal

block for connection of signal wires to an external

supply dispenser. The connection points are

marked 1, 2, 3 and C (common).

Water connections

NOTE

All plumbing must conform to national

and local plumbing codes.

Incoming water lines should not require non-

return or back-suction valves, as the machine is

already equipped with backflow prevention. Shut-

off 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.

• 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.

• 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.

Drain connection

Connect a 3" (75 mm) flexible drain hose to the

drain outlet of the machine.

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 Partno. 002008

For W185 Partno. 002009

These kits contain inlet hoses, drain hose, hose

clamps and washers.

Before the machine is operated, the door safety

interlock must be checked for proper operation

as follows:

• When washer loading door is open, the ma-

chine must not start. Verify this by attempting

to start washer with door open.

• When washer is in operation, the loading door

is locked and cannot be opened. Verify this by

attempting to open the loading door when the

machine is operating. If necessary, consult

this manual for proper operation of the door

lock and door safety interlock or call a quali-

fied serviceman.

direction.

7. When the program is in the Prewash cycle,

hot and cold water should be entering the

machine. In the Wash cycle only hot water

should enter.

8. If cold water comes in, the hoses are impro-

perly connected. Reverse hot and cold water

hoses.

9. Machine must spin in a counter-clockwise

direction, as seen from the front, during extra-

ction. If it does not, reverse lines L1 and L3 on

3-phase machines.

If the side panels of the washer move during

extraction, remove the shipping security which

connects the top rear of the cylinder to the

upper section of the back panel. It is used to

prevent shipping damage but has no function

when the washer is installed in a laundry. In

some rare installations this bracket may

transmit vibrations to the side panels. If it

does, remove the shipping security; otherwise,

leave it in place.

NOTE

All machines are factory tested prior to

shipment. Occasionally, some residual

water may be found when the machine is

installed.

After the machine has started and the door

automatically locked, the drain valve will close

and the hot and cold water valves will open to fill

the machine with mixed hot and cold water to the

level determined by the level control.

When this level is reached, both water valves will

close. During filling and then through the wash

program the drum has a reversing rotation.

At the end of the pre-wash, the drain valve will

open, whereafter hot water will fill to the level

determined by the level control. At the same time

detergent from compartment 2 is mixed with the

incoming hot water.

The water level controlled machine will now wash

the fabrics for 6 minutes. The machine is then

emptied.

Cold water is filled to the high level for the first

rinse which lasts one minute, followed by spin

extraction for 30 seconds. After the extraction

comes the second rinse in cold water, ending

with spin extraction, whereafter the third rinse is

started. Fabric softener is automatically admitted

during the third rinse. The fabrics are rinsed in

cold water for two minutes followed by a spin

extraction of four minutes duration. Finally there

is a shake out for one and a half minutes.

Machine construction

Outer shell

The outer shell is made of heavy gauge surgical steel and is attached to a heavy

duty, rigid head casting (back gable).

The whole assembly is mounted on a heavy gauge fabricated steel base,

galvanized for long life and corrosion resistance.

Panels

The machines are equipped with a top panel made of stainless steel. The front

panel is available in different colors or in stainless steel. The colored panels are

made of phosphatized steel plate. For servicing purposes, the panels can easily be

removed.

Inner cylinder

The inner cylinder is made of perforated surgical stainless steel. It is equipped with

three lifting ribs and has highly-polished side sheets and back with maximum

embossed perforated area to assure high flow of water and supplies through fabrics.

Scientifically correct ratio of cylinder diameter and depth assures maximum washing

action.

The shaft is electrically welded to the reinforced back of the cylinder. A specially

designed chrome-plated sleeve bushing protects the seals from wear.

1678

Fig.

Panels

The machines are equipped with a top panel made of stainless steel. The

front panel is available in different colours or in stainless steel. The colored

panels are made of phosphatized steel plate with electrostatically applied

baked enamel paint finish for rust and chip resistance. For servicing

purposes, the panels can easily be removed.

Back gable and bearing

The back gable and the bearing trunnion housing are constructed of a

webbed heavy casting for extra rigidity. The bearings are protected against

imfiltration of water by three neoprene seals. An intermediate safety outlet

provides an escape for any possible condensation.

The seals are mounted on a stainless steel, noncorrosive, specially harde-

ned sleeve bushing that is mounted on the drive shaft to prevent wear of

the seals and shaft. The main bearing is fitted machine-tight into the bea-

ring trunnion housing. A nut is tightened on the shaft to prevent the cylinder

from moving in and out.

The extension of the bearing trunnion housing supports the rear bearing

holding the shaft. A grease seal is mounted to prevent escape of grease.

The bearings are permanently lubricated and need no maintenance.

Wascomat's design transfers the weight of the loaded wash cylinder to the

largest possible surface area away from the bearings, for longest machine

life.

Door

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 alumi-

nium. 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 heat-

hardened 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.

Door lock

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.

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 bi-

metallic 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 bi-

metallic 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).

1148

1149

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.

Fig.

26 Mechanical and electrical design

Control unit

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

Fig.

Mechanical and electrical design

Relays

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

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 dia-

meters.

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.

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.

Water level controls

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

Fig.

Drive motor

Description in general

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 end-

shields 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.

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 satisfac-

torily 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.

7 and 9: motor overload protector.

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 installa-

tion check to ascertain that the windings are not

damaged. A burned out motor can be re-wound.

NOTE

Before connecting a separate overload

protector consult the local code.

Single-phase W125 and W185 machines are

also equipped with a manually resettable

overload protector mounted on the extract relay

in the control unit. This overload protector

protects the motor during the start-up of the

extraction.

Removing the motor

•Remove the drain valve (1) from the long shaft

by pulling it straight up.

• Remove the tensioning unit (2) on the rear of

the motor.

• Disconnect the connector (3) placed

diagonally under the rear edge of the motor.

• Remove the two screws (4). Pull the shaft

forward slightly until the guide pins pull out of

the shaft brackets. Remove the motor unit.

Inlet valves for W75, W105, W125

and detergent valve for W185

Construction

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

When the solenoid is energized, the spring-

loaded 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 diaph-

ragm, 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.

Maintenance instructions

Limescale can block the hole in the valve diaph-

ragm and interfere with the function of the valve.

It is therefore advisable to dismantle and clean

the valve at certain regular intervals. The fre-

quency 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.

• 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).

Dismantling the valve

• Pull the coil straight upwards. Use a screwdri-

ver if necessary to carefully undo the coil.

• Use the tool supplied with the machine

(attached to one of the hoses when the

machine is delivered) to open the valve

housing. Slide the tool over the protruding

plastic sleeve to that the pegs on the tool

engage the corresponding sockets in the

valve housing.

• Use a spanner or a pair of pliers and unscrew

the upper part of the valve housing.

Construction

The valve housing is made of pressed brass. The

spring-loaded plunger is made of stain-less steel

and located at its lower end is a rubber gasket for

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.

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:

1. Shut off the main supply.

2. Unscrew the orifice.

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

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.

Mechanical and electrical design

Soap supply box

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.

Maintenance

Preventive maintenance has been reduced to a

minimum by the careful design of reliable compo-

nents 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:

- Use a spatula to scrape loose any deter-

gent which may have stuck on the inside of

the dispenser.

- Flush the loosened detergent with warm

water.

- Wipe dry and leave lid open.

• 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

• 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

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

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.

If the machine does not extract

A Check the extract relay and relay coil

for proper operation.

If the motor does not operate at wash speed

A Check the wash relay(s).

B Check the normally-closed contact of the

extract relay.

C Check the motor and V-belt.

D Review procedures outlined under section ”If

machine does not start”.

Trouble shooting

If the machine runs slowly on wash speed or

there is a slapping or thumping noise.

A Replace the V-belts

If a metallic noise can be heard at rear of

machine

A Tighten the pulley on the motor shaft

If the door is leaking

A Check the door gasket. If the gasket is in good

condition, install a 4-7 mm rubber hose seal

around the entire gasket, using the slits

provided.

If water continues to fill without stopping.

A Check the hose attached to the level control

unit.

B Check inlet valves for dirt underneath the

valve diaphragm. To isolate the cause, shut

off power. If water continues to flow, inlet

valves have foreign material in them and

should be thoroughly cleaned.

If water continues to flow without filling the

machine.

A Check seating of the drain valve.
