Introduction

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!

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.

Installation

Machine foundation

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 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 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

concrete to form pad. Make sure the foundation is level.

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.

NOTE: Install the W105ES using the front and rear pairs of bolt holes. The middle pair is used when a W105ES is being installed in replacement of a W73, W74 or W75 washer. In that case the rear bolt holes are not necessary but may also be used.

NOTE: 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

• 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 concrete.

• 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 Connections:

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.

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: Check the incoming power for any high voltage

leg by measuring voltage from each leg to ground. If a high leg 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.

Fig.

Page 14

Installation

Water Connections:

NOTE

All plumbing must conform to national and local plumbing codes.

Incoming water lines do not require non-return or back flow prevention valves, as the machine is already fitted with an approved siphon breaker. However, all incoming lines must be fitted with shut-off valves.

• Water inlets are labelled for hot and cold water connection. The W185 has two hot water and one cold water connections.

• Flush the water lines thoroughly

before hooking hoses up to the washers, then check that all water valves are attached tightly and inlet screens not clogged. Use teflon pipe tape if necessary to ensure watertightness.

• Use 1/2" or 3/4" diameter reinforced rubber hosing not to exceed 6 feet in length. Let the hoses hang in a 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.

Depending how large your laundry is, your main incoming water line will generally be between 1-1/2" to 3" diameter to assure adequate water supply.

How to size water supply piping for Wascomat coin laundries

1. Calculate the total number of gallons of water that would be needed if all present (and future) washers were to fill at the same time. Assume the W75 (18-lb.) uses 7 gallons per fill; W105 (25-lb.) uses 10 gallons per fill; W125 (35-lb.) uses 14 gallons per fill‚ W185 (80-lb.) uses 20 gallons per fill; and W244 (75-lb.) uses 30 gallons per fill. If water pipe runs of 70 feet or longer are required, multiply by 1.25 to compensate for pipe friction which reduces flow rates.

2. Using the Flow Chart below and knowing the water pressure in the water main at your store, select a pipe diameter that has a gallons per minute (gpm) flow rate the same or higher than the total calculated above. The hot water line and the cold water line supplying the washers must

each be this size diameter, since many fills are all hot or all cold. This will assure fill times of approximately 1 minute and normal cycle times. Wascomat washers are designed to operate at 25–85 PSI Call your local water utility company if you do not know the water pressure in your water main.

3. The water line from the laundry to the water main in the street must carry

double the total gallons capacity calculated in paragraph 1. Select the correct diameter from the Flow Chart. (You will note from the chart that two 2'' pipes do

not equal the flow rate of

a 4 inch pipe; two 1'' pipes do

not equal the flow rate of a 2 inch pipe, etc... Use the

correct gpm flow rates!)

Page 16

Drain Connections:

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

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.

Start-up and safety checklist

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

• Make sure the machine is properly bolted to the floor and level.

• 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.

Before the machine is operated, the door lock must be checked for proper operation as follows:

• When washer door is open, the machine must not start. Verify this by attempting to start washer with door open.

• When washer is in operation, the door is locked and cannot be opened. Verify this by attempting to open the door when the machine is operating. If necessary, consult this manual for proper operation of the door lock or call a qualified serviceman.

IMPORTANT:

Door lock must be checked daily in accordance with above procedure.

WARNING: Before servicing Wascomat equipment,

disconnect electrical power.

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.

Function control check-out list

In the cylinder you will find the warranty registration card, a copy of the warranty policy, the bolthole template, wiring diagram, and other pertinent material. The warranty card must be completed and sent to Wascomat immediately or your warranty coverage will start from the day we shipped the washer from our warehouse. All other items should be placed in a safe place for future reference.

The machine should be cleaned when the installation is completed, and checked out as detailed below without loading the machine with clothes:

1. Check the incoming power for proper voltage, phase and cycles.

2. Open water taps to the machine.

3. Turn on electric power.

4. Check the door lock as detailed in this manual.

5. Select the Warm cycle and then press the START button.

6. Run through a complete Warm cycle, checking for proper water temperature, drain operation and extract direction. To rapid advance the timer, press and hold down the START button until the indicator arrows reach the desired part of the cycle.

7. Now select and run the Cold cycle. There is no hot water in the Cold cycle so if hot water enters the hoses are improperly connected. Reverse the hot and cold water hoses.

8. The drum must extract in a counter-clockwise direction as seen from the front! If it does not, reverse incoming electric lines L1 and L3.

NOTE:

All machines are factory tested prior to shipment. Occasionally, some residual water may be found when the machine is installed.

Operating Instructions

Insert required number of quarters as shown on the display, which counts down quarters as they are inserted. Press START button when the display shows 00.

A clock symbol will now appear and remaining wash time in minutes counts 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.

Figure 31 illustrates a temperature display function only available on washers with built-in heating, which are not used in North America.

Rapid Advance

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

• 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

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.

Fault-finding Program

If there is a power failure the washer will remember the selected cycle for about 8 -10 minutes. The cycle will restart automatically when power is restored.

Certain faults are automatically detected and indicated by a number code shown in the Information Display .

For fault codes 01 and 02 restart may be attempted after the fault has been corrected. For all other faults power to the washer must be turned off and on again before the washer can be restarted.

If fault codes 03-09 appear, contact authorized service personnel.

Fault Code Cause of fault

01 Water level too low. Open water

taps. Check level control. Check drain valve for leak.

02 Door lock fault. Open and lock

door again. Replace if necessary.

Coin-operated machines

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.

• 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.

Fig.

Page 30

Programming

1031

Fig.

• 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.

• 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.

Wiring for automatic price reduction

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.

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

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.

Fig.

Page 32

Programming

1046

1474

1475

• 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.

• 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!

OPTION BUTTONS:

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!

Mechanical and electrical design

Relays

The Wascomat Emerald series 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 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.

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.

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

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 chrome-plated, 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.

Page 47

Mechanical and electrical design

Door, description

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

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 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.

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 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.

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 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 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.

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 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.

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.

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 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.

Maintenance instructions

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

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

Trouble shooting

If the valve does not open

• Check that power is supplied to the coil.

• Check the coil with an instrument to determine whether there is a break or a short circuit.

• Disassemble 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).

Disassembling the valve

• Pull the coil straight upwards. Use a screwdriver 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 wrench 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.

Soap supply box

The three-compartment soap supply box is located at the top of the machine. Viewed from the front, the compartments marked with figures 1, 2 and 3 are used as follows:

Compartment 1 This compartment is used for adding detergent at the beginning of the

Prewash cycle. Powders may be loaded immediately; for liquids, wait until the display shows an arrow and the compartment flushes with water.

Compartment 2 This compartment is used for adding detergent at the beginning of the Wash

cycle. If bleach is used, it is added to this compartment when the display arrow appears.

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 when the arrow appears.

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 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

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 (9) is undamaged.

If the drain valve doesn’t open:

• Check that the return tube (8) is open.

• Check that the piston (4) doesn’t seize.

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 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 top panel and carefully clean

the rubber gasket on top of the soap box so it tightly seals to the top panel. If you do not maintain a tight seal you risk suds overflow onto the door lock.

Every three months

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

• 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

If the machine does not start

A Check the circuit breaker in the power line to

the machine.

B Check the door lock, including cable. C Check the glass cartridge fuses. D Check for loose wires at main power terminal

block.

If water does not drain

A Check the drain valve for clog. Check the

drain solenoid (located next to the water valves) for proper operation.

B Disconnect the drain hose connected to the

main drain line. If a full flow of water comes out, the problem is in the main drain line. If water flow is slow, the problem is a clog between the drain valve and the drum. Clean out the drain valve completely, including the rubber boot at the top of the drain valve.

If fuses continually blow

A Check the door lock, including cable B Check for short circuit.

If timer rapid advances or stops during cycle

A Check the door lock, including cable.
