The Wascomat Junior, Super Junior, Senior and Giant models washer/
extractor has been developed to cover the heavy duty requirements of
hotels, motels, nursing homes, hospitals, professional laundries,
restaurants, airlines, steamships, schools, colleges and all on-premises
laundries where high quality automatic washing and quick formula variation
are required.
The machines offers five pre-set wash programs Hot, Warm, Cold, Permanent Press and Delicate which can be selected by turning the program
selector on the front panel. These programs are designed to suit a variety
of fabrics and offer different water temperatures, water levels, wash periods
and supply injection. 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.

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 is delivered with each machine.
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 concrete to form
foundation. 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.

board and door are both made of enameled
aluminium. The backing board is bolted directly
to the outer shell of the washing machine.The
door hinges are fastened on the outside of the
backing board and the door lock (5) on 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.
F
NOTE
Do not repair a faulty door lock.
Allways replace the old unit
with a new one, to assure proper operation of the door safety
interlock.
26
Door lock, description
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.
F
2
3

1
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 drag magnet (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
drag magnet 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 drag magnet
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 drag magnet 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 drag
magnet. The drag magnet operates for about
two minutes to allow the bi-metallic spring to
cool enough not to lock the door again.

Relays
29
The Wascomat HI-TEK models employ three
relays. The relays control:
F
• the reversing wash of the wash motor (1,2)
• the extraction motor (3)
Construction
F
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.
1152
30
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.

Drive motor
21
31
Description in general
F
F
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
32
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.

each winding 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.

Water level controls
F
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.
Water level
As a guide for checking the level control for proper functioning, the
normal level should be at the bottom of the door glass.

Inlet valves
27
37
Construction
F
The 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
F
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.

Repair instructions
39
Limescale can block the hole in the valve diaphragm and interfere with the function of the valve.
F
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.
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.
1186
40
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
F
F
• Pull the coil straight upwards. Use a screwdriver if necessary to carefully undo the coil.
• Use the tool supplied (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.
1187

Inlet valve for W185
F
29
42
The water inlets have brass bodies with larger
cross section of the outlet in order to achieve a
shorter filling time for the machine.
Construction
The valve housing is made of pressed brass. The
spring-loaded plunger is made of stainless steel
and located at its lower end is a rubber gasket for
the pilot valve.
Operation
The valve is automatically operated by means of
a rubber diaphragm and a pilot valve in exactly
the same way as the supply injector valve.
NOTE: To strip, clean, re-assemble and
troubleshoot the inlet valve, follow the
instructions outlined for the supply injector
valve.
0311

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.
F
F
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.

Drain valve
31
46
Description
F
The drain valve is steered using the pressure in
the cold water intake. A hose (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
hose (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 hose (8).
Trouble shooting
If the drain valve doesn’t close:
• Check that the solenoid valve (2) receives
electricity. The drain operation can be
checked using the washing machine’s built-in
service program (see section titled ”Service
Program”).
• Check that the solenoid valve and the hoses
are clear by:
- removing the drain hose (3).
- activate the machine’s service program
(see section titled ”Service Program”) and
change the program to allow direct control
over the drain valve.
- check that water exits the hose when the
valve is activated.
• Check that the diaphragm (9) is undamaged.
If the drain valve doesn’t open:
• Check that the return hose (8) is open.
• Check that the piston (4) doesn’t seize.

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
high 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 soak, 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.
On reaching the low level, the hot water valve will
close.
The water level controlled machine will now wash
the fabrics for 6 minutes. The machine is then
emptied and the first extraction is started.
After this extraction 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 half a minute.

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
82
- 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.
81
• 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 hose from drain connection and
clean inside drain valve.
Every three months
Fig.
82
• Remove the cover plates 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
83
A useful aid in trouble shooting is the ability to
check individual switches and level sensors and
to control individual functions independently.
These techniques are described in the section on
”Service Programs”.
If machine does not start
Fig.
83
A Check circuit breaker in the power feed line to
the machine.
B Check door safety switches.
C Check glass cartridge fuse.
D Check electrical auxiliary contact on extract
relay.
E Check for fault indication on display (see
under the heading ”Service Information”).
If water does not drain
Fig.
84
A Check for fault indication on display (see
under the heading ”Service Information”).
B Check drain valve for proper operation.
C Disconnect drain hose connected to drain line.
If 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 valve body of any
foreign objects found.
