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 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:

F

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.

F

1. 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.

2. Wet the hole well. Brush the bottom and sides with cement grout.

3. Prepare a casing and fill with concrete to form foundation. Make sure the foundation is level.

F

1. 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.

Mechanical installation

• Place wide steel shims 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.
• 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.

Electrical installation

Although the machines are fitted with a thermal overload 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.

Connect L1, L2, L3 and ground wires according to the markings of the terminal block. The cable is to hang in a large loose loop, supported by the clip of the terminal block.

After installation, do the following:

Check the incoming power for a high voltage leg. If present, connect that line to L2 on the terminal block.

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 intercharge line L1 and L3 at the power connection terminal.

Check that the transformer on the control unit is correctly strapped in relation to the incoming voltage. The different alternatives is printed on the transformer circuit board.

Drain connection

Connect a 3" (75 mm) flexible hose to the drain outlet of the machine.

The drain hose must not have sharp bends and must slope from the machine to assure proper drainage. The outlet must open freely to the main drains.

Do not reduce the size of the drain connection from the machine to the waste line.

Start-up and safety checklist

Before initial start-up of a Wascomat washer-extractor, the following safety checks must be performed:

• Make sure the machine is properly bolted to the floor.
• Make sure that all electrical and plumbing connections have been made in accordance with applicable local codes.
• Use only flexible water fill and drain hoses of the proper length to avoid sags and kinks.
  • Make sure the machine is properly grounded electrically.

Door, description

F The door consists of: backing board (1), door (2), glass (3) and door gasket (4). The backing 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.

Door lock, description

F 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 micro-switch (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 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.

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.
• 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).

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.

Control unit

The control panel, mounted at the front, includes all components necessary for operating the machine, such as display window, control lights and a program selection knob.

The printed circuit board (1) with the microprocessor-controlled electronic timer is mounted just behind the control panel.

Relays (2), transformer (supplying the printed circuit board) (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.

Technical diagram of an electronic device with labeled components including a circuit board, battery, and motor assembly.

Relays

The Wascomat HI-TEK models employ three relays. The relays control:

• the reversing wash of the wash motor (1,2)
• the extraction motor (3)

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 continuous 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.

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

Description in general

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 end-shields 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 continuous connected capacitor, while the 2-pole winding (extract-speed) is a specially designed winding with both continuous connected capacitor and 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 synchronous 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 connections

1, 2 and 3: wash speed (18-pole winding).
4, 5 and 6: extract speed (2-pole winding)
7 and 9: motor overload protector.

Motor overload protector

The motor is equipped with two self-resetting, thermal overload protectors, situated one in the 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.

NOTE

Before connecting a separate overload protector consult the local code.

Single-phase W125 and W185 machines are also equipped with a manually set 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 axle by pulling it straight up.
• Remove the tightening 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 axle forward slightly until the guide pins pull out of the axle brackets. Remove the motor unit.

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.

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

Construction

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

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 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.

Technical line drawing of a mechanical valve assembly (no text or symbols)

Repair instructions

Limescale can block the hole in the valve diaphragm and interfere with the function of 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.

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 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.
• Use a spanner or a pair of pliers and unscrew the upper part of the valve housing.

Inlet valve for W185

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.

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 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 pressure 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.

Program group 1

Wash program, Hot

Fig. 75 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.

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:
• 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

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. 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. 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.
