General
Wascomat EMERALD SERIES washer/extractors have been developed to
meet the needs of state-of-the-art professional laundromats. EMERALD
models are unique because you can program different prices for the seven
wash cycles, giving the customer a real choice and allowing you to maximize revenue by charging what each cycle is worth. In addition, you can
charge a higher price if the customer selects the Extra Extract option. Using
an external clock and wiring harness, these models may be programmed to
lower prices by any percentage between any hours of any days, for the
ultimate in pricing flexibility!
Fig.
1
The seven cycles offer different water temperatures, wash times, extraction
times, and normal or gentle drum rotation. EMERALD SERIES washers
achieve maximum environmental efficiency because only the minimum
amount of water is used for each cycle, which vary in duration.
When ordering spare parts or contacting Wascomat or your dealer for
service, always give the machine serial number, model, voltage and other
electrical characteristics appearing on the data plate at the top left of the
rear panel of the machine. The serial number is also printed on a sticker
inside the door.

The machines are designed to be securely bolted
to a concrete pad. A template showing the size of
the pad and positioning of the 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 pad should be made. A
prefabricated steel base is available for mounting
machines without pouring a pad.
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 pad to the wall, and the distance from the
pad to the nearest side wall. The distance
should be at least 16 and 12 inches,
respectively. Leave 3/4'' between washers.
2. Break up the floor to a minimum depth of 3
inches, making sure that the sides of the hole
slope away - 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 bolts
correctly. Bolts are to extend 1 1/2" above the
concrete.
NOTE: A prefabricated steel frame, designed
to be placed in the concrete instead of the
individual mounting bolts, is available from
Wascomat.

If you form a lip on top of the concrete pad
in front of the washers, be sure you leave
enough room to remove the bolts which
secure the bottom of the front panel and
enough room to swing out and remove the
panel!
Mechanical installation
Before mounting the machine:
Fig.
5
• Place wide steel shims or washers on the
concrete foundation 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 since this can damage the door
and door interlock.
Fig.

• 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 of the base. Spacing washers
must be used to take up the space if one or
more of these points is not resting against the
floor/foundation.
• Place the flat washers delivered with the
machine over the foundation bolts. Secure the
machine in position by tightening the
selflocking nuts. Se illustration.
• Check and tighten the nuts every week for the
first month to compensate for any setting of
the foundation.
0950
IMPORTANT
The bases for the W75 and W105 machines
have 6 bolt holes. For the W75 use the front
and middle ones. For the W105 use the front
and rear most ones. For the W125 and W185
make certain to use all 6 bolt holes.

Although the machines are fitted with a thermal
overload in the motor windings, a separate threephase common-trip circuit breaker must be
installed for all three-phase machines. Use an
inverse-time circuit breaker only.
For proper circuit breaker protection, check the
data plate at the rear of the machine. Also
consult local electrical code for special
requirements.

Connect L1, L2, L3 and ground wires according
to the markings of the terminal block. The cable
is to hang in a loose loop, supported by the clip
of the terminal block.
After installation, do the following for 3-phase
machines:
Check the incoming power for any high voltage
or "stinger" leg by measuring voltage from each
leg to ground. If a high leg (measuring more than
150 Volts) is present, connect that line to L2 on
the terminal block, which goes to the motor
circuit.

Start the machine and check that the drum
rotates in the proper direction during extraction,
i.e. counter-clockwise when seen from the front.
If the drum rotates in the wrong direction switch
lines L1 and L3.
Check that the transformer on the control unit is
correctly tapped for the incoming voltage. The
different voltage alternatives are printed on the
transformer circuit board.

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.

• 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.

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.
1833
NOTE
To simplify installation, Wascomat has
made available the following hose kits:
For W75, W105 and W125Part. No. 002008
For W185

Insert required number of quarters as shown
on the display. This will count down the quarters
as they are inserted. Press the START button
when the display shows 00.
A clock symbol will now appear and the
remaining wash time in minutes will count down.
(The time for each cycle will not be displayed
until the cycle has been run once completely
from beginning to end, so the microprocessor
knows how long it should take). The
microprocessor retains in memory how long it
took to run each cycle the last five times and
displays the average time. Since water pressure
may fluctuate affecting fill times, the displayed
average cycle time is not always exact and may
vary from machine to machine. If you find cycle
times taking longer and longer, use that information as a warning that your water inlet screens
may be clogged, extending fill times, or some
other problem may exist.

Within 5 minutes after starting (only while the
colon : is flashing), steps of the wash cycle can
be skipped by using Rapid Advance.
Fig.

• Press and hold down the START button until
the arrows rapid advance. Stop pressing
where you want the cycle to continue.
• If during the first five minutes of a cycle a
customer realizes they put a wrong item of
clothing in the washer (for example a brightly
colored shirt mixed up with white sheets), you
can rapid advance through the entire cycle,
open the door and remove the item, then lock
the door and press START again to continue
the cycle from where you began rapid
advance. No money is lost and no extra time
is gained. The remaining time will not be
displayed.

Changing Wash Programs While Washing
Fig.
31
If within 5 minutes after starting a cycle (only
while the colon : is flashing) a customer realizes
the wrong cycle has been selected, they can
push the START button once briefly to put the
washer on pause. They may then press a
different wash cycle button and press START
again to continue from the same step in the new
cycle.
If the customer selects a different cycle or Extra
Extract option that costs more money, the
washer will not start again unless additional coins
are inserted as shown on the Information
Display. There is no way for a customer to pay
for a less expensive program and switch to a
more expensive program without paying for it, or
to gain additional free wash time.
Note: Rapid Advance is only possible during the
first five minutes of a cycle, while the colon : is
flashing. However, if the START button is
pressed after five minutes has elapsed it will put
the wash cycle on pause, which means washing
stops, the clock stops counting down remaining
wash time, and an arrow flashes on the
Information Display at which ever step the wash
cycle was in when pause began. Press START
again to resume washing. Be alert to any
accidental pauses, which are unlikely but
possible.

Programming
Coin-operated machines
19
32
The prices of the various wash cycles must be
programmed into the microprocessor. On
EMERALD SERIES washers you can program
different prices for the seven cycles!
You can also program the prices to drop by any
percentage between any hours of any days,
automatically!
Price programming
• Remove the coin box.
• Press one wash cycle button so an arrow
points to it.
Fig.
32
Fig.
33
• Toggle and hold the price programming switch
located at the back of the coin box in the PP
(price programming) position.
This transforms the various buttons into a
numerical keypad. Numbers 1 - 7 are on the
wash cycle buttons, the Extra Extract button is
8, and the Gentle Wash button is 9. The
START button is 0.
1473

1030
Programming
20
Fig.
34
• Program the price by using the keypad to
enter the number of quarters needed to start
the selected wash cycle. For example, press
"1" and "2" to enter 12 quarters for a $3.00
vend price.
34
• Release the price programming switch. Price
programming of one wash cycle is now
complete. Repeat for the other six cycles,
using any prices in quarters you want.
If you want to raise prices if Extra Extract is also
selected, first program prices for each of the
seven wash cycles. Then program a different
price for each wash cycle plus Extra Extract. For
example, program a price for the Hot cycle. Then
press the Hot button and the Extra Extract button
so arrows point to both. Now program a new
price for the combination of Hot plus Extra
Extract. Typically you would program a price for
the combination that is one quarter higher, but
that's totally up to you. If you later change pricing
of a cycle don't forget to change pricing of the
combination with Extra Extract.
Use of the Gentle Wash button cannot affect
pricing.
Programming Tip:
Too many different prices may confuse
customers. We suggest using three or four
different prices for the seven wash cycles.
Typically Heavy Soil will be the most expensive,
Hot and Warm the second most expensive,
Quick-Wash, Delicate, and Permanent Press the
third most expensive, and Cold least of all. But as
always, pricing is totally up to you. Wascomat
EMERALD SERIES washers give you complete
price flexibility so you can maximize revenue and
beat the competition.

Programming
Wiring for automatic price reduction
Fig.
35
Emerald washers have a price reduction terminal
block located next to the main power terminal
block. Your installer must run a pair of wires from
each washer terminal block to Wascomat's
automatic price reduction relay box (Part No.
098887), which can control 16 washers. Each
relay box can be expanded to handle up to 32
washers by adding snap-in contacts (Part No.
510192). The relay box is plugged into a
programmable appliance timer clock (such as
Radio Shack model 63-892) which you program
with the days and hours you want automatic price
reduction to be on or off. Refer to technical
instruction No. 1040 for detailed installation
instructions.
21
35
L1
L1
1838
36
Programming automatic price reduction
Price reduction is programmed into each
individual washer as a percentage reduction of
the normal prices. For example, if a cycle is
normally eight quarters and you program a 25%
price reduction, the reduced price will be 6
quarters. An external clock is programmed with
the days and hours you want the price reduction
to activate and deactivate. (This clock has
nothing to do with the clock symbol on the
Information Display, which counts down
remaining wash time).

• Press the Extra Extract button until only the
arrow that points to it is lit.
• Toggle and hold the price programming switch
at the back of the money box compartment.
This transforms the buttons into a numerical

buttons, the Extra Extract button is 8 and the
Gentle Wash button is 9. The START button
is 0.

Programming
22
• Enter the desired percentage reduction using
two numbers (for example, enter 2 and 5 for
25% reduction). If you make a mistake just
press the START button (0) to clear the data.
Prices will round up to the nearest quarter
when price reduction is active.
39
• Release the price programming switch. Programming is now complete. Check to see that
your regular prices appear on the display after
you select a cycle. If not, just toggle the
programming switch once to reset the system.
Since price reductions are programmed into each
individual washer you can program different
percentage price reductions for different size
washers, or you could connect your various size
washers to separate clocks and program the
clocks to reduce prices on different days or at
different times. With Wascomat Emerald Series
washers there is virtually no limit on your ability to
create innovative price promotions to build your
business, maximize profits, and eliminate any
correlation between water consumption and
revenue!

Coin counter
The microprocessor features a built-in coin
counter which uses a four-digit number (0000 9999) to indicate how many coins have been fed
into the meter. The coin counter can only be reset
to zero with a special microchip from Wascomat,
so if someone else does your connections, you
can check the reciepts.
A coin count reading is made as follows:
• Press one of the cycle selection buttons
repeatedly until the only arrow lit is the bottom
left arrow (open door arrow).

• Toggle and hold the price programming
switch.
• The two lower digits (for example "18") of the
four-digit coin count number (for example
6,518) will now appear in the Information
Display. Release the programming switch.
• Toggle and hold the price programming switch
while also pressing any one of the wash cycle
buttons. The two higher digits (for example,
"65") of the coin count number will now appear.
A total of 6,518 quarters have been inserted
into this washer. If your log book shows the
count was 6,200 last time you collected, then
6,518 minus 6,200 equals 318 quarters, which
should be in the money box!

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. At the same
time detergent from compartment 1 is mixed with
the incoming water.
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 prewash, 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.
Hot and cold water are filled to the medium 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 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

EXTRA EXTRACT -- Selecting this option adds 4
minutes to the final extraction of any cycle. For
example, the HOT cycle plus EXTRA EXTRACT
gives the customer a total of 8 minutes
extraction. You can easily program the washer to
charge more money (usually one more quarter) if
this option is selected! The effect of extra
extraction depends on the type of laundry washed, load size, etc.
GENTLE WASH -- The normal wash action of a
Wascomat washer is 12 seconds rotation, 3
seconds pause, reverse direction and repeat.
Selecting the GENTLE WASH option converts
the selected wash cycle to gentle action, which is
3 seconds drum rotation and 12 seconds pause,
reverse direction and repeat. The DELICATE
cycle always uses gentle action so it is not
affected by this option. There is no extra charge
to the customer for this option, so it is simply up
to them to choose their preference. You may
want to advertise and promote this option since
market research indicates there are people who
believe certain clothing items are too delicate to
wash in a commercial washer. Now you have the
answer!

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
coloured 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
Fig.
51
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 hardened sleeve bushing that is mounted on the drive shaft to prevent wear of
the seals and shaft. The main bearing is fitted machinetight into the bearing
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.

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 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.

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

Door lock
Fig.
53
The door lock consists of a circuit board (1) with
a connector. The following parts are mounted on
the board: 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 card
which acts to lock the locking bolt in place when
the machine starts up. The 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.
5
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.

Relays
Fig.
55
37
55
The Emerald series models employ three 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.
56
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.
1866
56
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
Fig.
57
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.

58
Description in general
Fig.
58
Fig.
59
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 tightener
on the rear side of the motor. The motor and
tightener unit 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 consists 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 continous connected capacitor, while the
2-pole winding (extract-speed) is a specially
designed winding with both continous connected
capacitor and starting capacitor.
1153
59
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 and
W125 and detergent valve for W185
63
Construction
Fig.
63
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.
64
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.

Drain valve
73
Description
Fig.

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 and the springs
(7) on the lid push the piston back, allowing the
water to pass the solenoid valve and drain out via
the return tube (8).

Trouble shooting
52
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 separate 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 symptoms 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.
