Installation & Operation
All washers must be installed in accordance with all local, state and national building,
electrical, and plumbing codes in eect in the area.
Foundation Requirements
The washer must be securely bolted to a substantial concrete oor or mounted upon a suitable base
which is in turn securely bolted to a substantial concrete oor. Care must be stressed with all foundation
work to ensure a stable unit, eliminating vibration. All installations must be made on sound concrete oors
8” or thicker.
Mounting
A concrete pad or steel base which elevates the machine 4 inches above the oor level is recommended
to provide easy access to the loading door. Allow a minimum of 24” of clearance behind the rear of the
machine for service as is shown. Six bolts are required to mount the washer to the steel base or concrete
pad.
Mounting Holes
The following pages illustrate the mounting dimensions for the machine and also show a typical concrete
pad arrangement. Note: Mounting bolts should be checked frequently to ensure that they remain tight.
The machine should be checked with a spinning load to be sure there is no unusual vibration or movement
between the machine and the base or oor.
Plumbing
Water supply hoses are furnished with each machine. The threaded connections on the hoses are
standard garden hose type thread. Separate hot and cold water lines with shut o valves or faucets for
inlet hose connections must be provided, maintaining 30 to 120 psi. water ow pressure. A hot water
recovery rate of approximately 70 gallons per hour is required with normal wash and cold rinses. A hot
water temperature of 140 degrees Fahrenheit is recommended for best washing results.
Drain
The drain outlet tube at the rear of the machine is 3” in outside diameter. A exible hose (Pt. No. 9242-
417-003) is available to extend the drain system. Adequate fall must be maintained for proper drainage.
Protective Film
The machine may have protective adhesive lm on the front escutcheon area and the front and side
stainless steel panels. The lm may be peeled o before putting the machine into service.
Electrical
Dexter WCN55 series washers are intended to be permanently installed appliances. The machines should
be connected to an individual branch circuit not shared by lighting or other equipment. The electrical
connection should be sheathed in water proof exible conduit, or equivalent, with conductors of the
proper size and insulation (suggested size below). A power cord is not provided. The following diagram
shows the proper power connections to the rear terminal block for both 1 and 3 phase machines. Wiring
should be performed by a qualied person.
Electrical power connections are made to the terminal block located at the upper right-rear corner of the
washer (viewed from the front). The terminal block is accessed by removing the cover.

Electrical Path Circuit Schematics
Timer Sequence Chart
The timer sequence charts are used in conjuction with the wiring diagrams to trace the circuitry during the
time cycle. The timer contacts and the operation or component that each contact controls are listed down
the left side of the chart. The phases of the complete cycle are shown across the bottom of the chart. The
timer switch increments are numbered across the top of the chart. The solid horizontal bars in the chart
denote when the various contacts are closed during the cycle.
To use the timer sequence chart to trace the circuitry:
1. Locate the particular part of the cycle on the sequence chart.
2. Determine which timer contacts are closed during that particular step of the cycle by noting the solid
vertical bars in that step across the chart.
3. Draw in the gap of the respective contacts on the wiring diagram with a soft dark pencil, to illustrate
the contacts are being closed.
4. Similarly, determine which switch contacts are closed, by the switch chart, and illustrate them as closed
on the wiring schematic.
5. The circuitry during the particular step of the cycle may then be easily traced on the wiring diagram,
since all contacts and switches are then properly illustrated as being open or closed.
Start Circuit
Power travels into the control trough on L1 &L2. 240VAC goes to a Control Transformer that steps the volt-
age down to 120VAC for the controls. 120VAC then travels thru the 1.5 amp Circuit Breaker and travels on
the white/red wire to the Coin Accumulator Transformer where it is stepped down to 12VAC. This 12VAC
powers the Coin Accumulator Board via the gray wire. With the board now powered up, the insert coins
light will be illuminated and it’s ready to count coins.
120VAC is also supplied to the Main Timer Start and On-O Contacts on the white/red wire. The Start
Contact is closed before the machine has been started so 120VAC travels through the Start Contact and is
sup plied to the Coin Accumulator Board Start Relay. The S4 Coin Switch counts the quarters and sends a
signal to the Coin Accumulator Board. When the coin count is satised, the Coin Accumulator Board closes
the Start Relay and sends a short 120VAC signal on the orange/white wire to the Rapid Advance Timer
Motor. This timer motor starts advancing the Main Timer to the preselected starting position. A few sec-
onds after the Coin Accumulator Board sends the start signal to the Rapid Advance Timer Motor, the Coin
Accumulator Start Relay opens, the display goes blank and the On-O Contact in the Main Timer closes to
ensure that the S1 Door Switch is closed (showing that the door is locked). The On-O Contact also pro
vides 120VAC to the On Light on the red wire. With the S1 Switch closed the Door Lock Solenoid is now
powered with 120VAC via the white/red wire. The Door Lock Solenoid pulls in, locking the door and closing
the S2 and S3 Switches. The S2 Switch is a backup to the S1 Switch so that the adjustment on S1 isn’t as
critical. The S3 Switch provides 120VAC to Timer Contact RA-3 to power the Rapid Advance Motor again
and the Main Timer is allowed to advance on to the preselected start position. The blue wire furnishes the
neutral for the controls.
Fill Circuit-Warm
120VAC is supplied to the controls through the S1, S2, and S3 Door Switches. The On Light and the Door
Lock Solenoid (discussed in Start Circuit) will remain on throughout the cycle. The Lock Thermoactuator
Contact in the Main Timer is closed and provides the neutral side to operate the Thermoactuator. 120VAC
is provided.to the Lock Thermoactuator on the orange wire from the S3 Door.Switch. The Drain Contact in
the Main Timer is closed and pro vides 120VAC to the Drain Valve on the brown/yellow wire which closes
the valve. The Wash Contact in the Main Timer is closed and provides 120VAC to the Reversing Timer and
the Reversing Timer Motor on the blue/black wire. This will start the Reversing Timer operating which will
alternately open and close the Micro Switches that provide the direction of tumble for the wash basket.
The Wash Light Contact in the Main Timer is closed and provides 120VAC to the Wash Light. The orange
wire coming from the S3 Door Switch provides power to the Wash Water Contact in the Main Timer.
120VAC connects. from the Wash Water Contact to the Wash Temperature Contact via an internal timer
connection. With 120VAC on the orange wire & neutral on the orange/yellow wire, the Coin Accumulator
Board turns on the Time Remaining Light & starts counting down in minutes. (If delay ll kit is installed,
time count down is stopped during ll.)

Fill Circuit-Warm Continued...
Now a cycle must be selected with the Selector Switch. We’ll use Normal Wash. The washer lls the tub
through the back of the machine with either one or both the C1 Cold and H1 Hot Water Valves. At the
beginning of the cycle, the detergent dispenser ushes the detergent into the tub. This is accomplished
with the Wash Dispenser Contact in the Main Timer. 120VAC travels through the closed Wash dispenser
Contact and is supplied to the H2 Hot Water Valve Solenoid by the red/orange wire. As the washer lls
with water, the Wash Basket will tumble one direction for 19 seconds, pause, and then reverse direc-
tion for 19 seconds. 120VAC travels from the Wash Water Timer Contact to the Heavy Duty Contact in
the Selector Switch via the white/black wire. 120VAC goes through the closed Heavy Duty Contact in the
Selector Switch and energizes the C1 Cold Water Valve Solenoid via the white/orange wire. 120VAC also
travels to the closed Wool/Delicate Contact in the Selector Switch. This closed contact provides power to
the H1 Hot Water Valve Solenoid via the red/yellow wire. When the water reaches the predetermined level
the Pressure Switch moves to the full position and opens the neutral side of the line to the Water Valves.
This shuts the Water Valves o. The neutral for the Water Valves & Main Timer Motor is provided through
the Pressure Switch. The Main Timer is stopped until the Pressure Switch provides neutral when full level
is reached. Neutral for the Main Timer Motor during drain and spin is provided through the Delay Fill Timer
Contact.
120VAC travels from the Wash Water Timer Contact to the Heavy Duty Contact in the Selector Switch via
the white/black wire. 120VAC goes through the closed Heavy Duty Contact in the Selector Switch and
energizes the C1 Cold Water Valve Solenoid via the white/orange wire. 120VAC also travels to the closed

Wash Circuit
As the washer lls the tub through the back of the machine with either one or both the C1 Cold and H1
Hot Water Valves, the Wash Basket will tumble one direction for 19 seconds, pause, and then reverse
direction for 19 seconds. This is accomplished through the use of a Reversing Timer. 120VAC is supplied to
the Reversing Timer Motor on the blue/black wire from the Wash Motor Timer Contact in the Main Timer
and 120VAC is supplied to the R1 Run Relay any time the door is locked. This R1 Relay closes & provides
24VDC thru the Reversing Timer Wash Micro Switches. The Reversing Timer will alternately open and close
the two Wash Micro Switches and provide 24VDC to the FW (forward) or RV (reverse) terminals on the
Variable Frequency Drive.
As discussed in Start and Fill, the Lock Thermoactuator, Drain Valve, On Light, and Main Timer Motor (ex-
cept in ll) are all operating throughout the Wash Cycle.
Drain, Rinse 1 & 2, and Final Rinse Circuit
The Drain Contact on the Main Timer opens. removing power to the Drain Valve. The normally-open
spring-loaded Drain Valve opens and empties the tub.
For Rinse 1 & 2, the Rinse Light Contact in the Main Timer closes and provides 120VAC to the Rinse Light.
The Rinse Water Contact in the Main Timer also closes and provides 120VAC to the C1 Cold Water Sole-
noid. The tub will ll until the predetermined level is achieved at which time the.Pressure Switch Contact
will open the neutral side of the line shutting o the C1 Cold Water Solenoid. When the tub is full, the
pressure switch also closes a neutral circuit to the M1 Timer Motor and to the orange/yellow wire on the
Coin Accumulator Board. This allows the Main Timer to advance only after the tub is full and stalls the time
count down on the Coin Accumulator Board during lls.
For the Final Rinse, the. Final Rinse Light Contact in the Main Timer closes and provides 120VAC to the
Final Rinse Light. Rinse water is the same as in Rinses above.
As discussed in Start and Fill, the Lock Thermoactuator, Drain Valve, On Light, and Main Timer Motor (ex-
cept in ll) are all operating throughout the Wash Cycle.
Intermediate Extract Circuit
The Wash Contact remains closed and provides 24VDC to the closed Clockwise Micro Switch on the
Reversing Timer. 24VDC is then fed to the Counter Clockwise Micro Switch via a jumper wire..120VAC is
then sent to the Delay Spin Micro Switch. The Delay Spin Micro Switch provides 120VAC to the Spin Motor
Contact in the Main Timer on the blue/white wire. The Spin Motor Contact is closed for spin and the volt-
age continues on to the R2 Spin Motor Relay Coil on the red/black wire. With 120VAC to the R2 Spin Motor
Relay Coil two things happen. 120VAC is now provided from the orange wire directly to the Relay eliminat-
ing the Reversing Timer and the Micro Switches from the circuit.
The second thing that happens when the R2 Relay is closed is that 24VDC is provided from the DCM ter-
minal of the Variable Frequency Drive through the R1 Run Relay through the R2 Spin Relay to terminals Ml
1 & Ml3 on the Drive and the washer spins at intermediate speed.
Final Extract Circuit
Same as Intermediate Extract but adds the R3 Extract Relay. The Main Timer provides 120VAC to the
Extract Relay Coil. When this relay closes it provides 24VDC to the Ml2 terminal on the Variable Frequency
Drive. This means that all 3 terminals Ml1, Ml2 & Ml3 are powered for high spin.
Unlock Thermoactuator and Shake Out Circuit
The Lock Thermoactuator Contact in the Main Timer opens 1 1/2 minutes before the end of the cycle
removing the neutral to the Thermoactuator. This allows the Thermoactuator time to retract by the end of
the cycle.
To insure that the Lock Thermoactuator has retracted by the end of the cycle, 1 minute prior to the end
of the cycle, the Unlock Thermoactuator is powered with 120VAC through the Unlock Thermoactuator
Contact in the Main Timer.
The Spin Motor Contact in the Main Timer opens, stopping voltage to the R2 Spin Motor Relay & the mo-
tor. The basket will coast to a stop. The Wash Motor Contact in the Main Timer closes providing power to
the Reversing Timer once again (discussed in Wash Cycle). The washer will tumble for approximately 30
seconds to let the clothes shake loose and then stop.
End of Cycle Circuit
The On-O Contact in the Main Timer opens removing power to the Door Lock Switches and Contactors.
The machine is now stopped. The Start Contact on the Main Timer is closed providing 120VAC to the Coin
Accumulator Board on the white/green wire.
The End Of Cycle Contact in the Main Timer is closed sending a 120VAC signal to the Coin Accumulator
Board on the white/yellow wire telling it that the cycle is over. This does 2 things:
1. The beeper will signal for 3 seconds letting the user know that it is the end of the cycle.
2. It resets the Coin Accumulator Board and it is now ready to count coins again.

Step 1: Remove all screws holding back panel in position except the bottom row.
Step 2: The bottom row of screws are slotted and only need to be loosened and to lift o panel.
NOTE: The back panel is not only a safety requirement but also contributes to the rigidity
of the cabinet.
Drain Valve Access
For access, remove lower service panel. The drain valve is a ball type and is powered closed by the drain valve
motor. It is spring loaded open. If power is interrupted to the washer, the motor releases the sealing ball,
allowing the drive spring to open the valve. With the valve open, all water in the washer will drain out.
Chemical Injection Assembly
In the left rear corner of the washer is the chemical injection assembly. This is where all chemical hose
connections are made.
Drain Valve Cleaning
Step 1: Loosen the clamp on the tub hose at the drain valve end and remove the hose from the drain valve.

Detergent is ushed from the front of the compartment and fabric
softener is ushed from the back. There will be a small amount of
water left in the fabric softener compartment after each use.
Vacuum Breaker (also called an air gap)
In the left rear of the cabinet is the vacuum breaker. It guides
the water to the tub and dispenser and prevents a back ow of
water.
Water Valves
Remove top panel to access water valves. (see Removing
Top Panel) The two dual outlet water valves are mounted
to the rear channel with two screws each. Always check
inlet screens to be sure that they are clean. Disassembly
requires the removal of two solenoid screws and three valve
body screws. Below the solenoid coil is a solenoid guide,
armature, armature spring and diaphragm. All valve parts
are available individually or as a complete unit.

Door Lock Assembly Operation
After loading the clothing, the door should be closed and latched. The locking cam on the door contacts
the latching switch actuator which closes the latching switch. The specied number of coins should now
be added to start the washer. The gear motor pulls up on the locking pawl by use of a linkage rod. The
locking pawl has two jobs. The rst is to lock the door. This is accomplished by blocking the locking cam
on the door so that it can’t rotate to unlock. The second job is to close the two piggyback lock sensing
switches. These switches control power to all of the controls. If the door unlocks for any reason, these
two switches will stop the machine. When the door handle is 1/4 to 1/2 of an inch from its fully closed
position, the latching switch should close. The two piggyback lock sensing switches should be open when
the door is unlocked and should be closed when the door is locked.
Accessing the Door Lock Assembly
After removing the front panel and masking ring, the door lock assembly can now be accessed.
Adjustment for Door Lock Assembly
The latching switch and the piggyback lock sensing switches all have slotted mounting for easy
adjustment.
Step 1: Set door cam over pin. Here you can see
the door cam away from the door lock
assembly.
Step 2: Tighten spring screw on switch actuator
bracket arm until it just clears cam OD. at
base of door lock assembly.
Adjustment to this bracket usually
is not necessary as next step is used
more in eld.
Step 4: Check for switch actuation at partial
turn of cam as in operation above. Door
handle goes from horizontal to six o’clock
vertical.
Step 3: With switch actuator bracket adjusted you
will now need to adjust single switch by
loosening 2 at brade screws and allowing
swivel of switch. Move switch towards above
bracket until it actuates. Now tighten at
blade screws. Use a .040 thickness guage to
insert between bracket and switch and the
switch should close and open again upon
removal of thickness guage.
Step 5: Check that lock pawl arm swings to cam
lobe to lock position.
Step 6: The lock stacked switches (piggyback)
must be adjusted as door lock solonoid
pulls up on door rod and locking pawl is
now blocking door cam from turning and
is in full up position. The stacked swtiches
(piggyback) have a single actuator arm
and it must actuate when single actuator
roller wheel rolls to at side of locking
pawl. You will also notice a .040 gap
between actuator arm and switch bodies.
Note: Both stacked switches must operate
together!

Door Locking Solenoid
The door locking solenoid is powered shut with control voltage to lock the door and releases
when voltage is removed. It is located in the left front corner of the washer.
Thermoactuators
The thermoactuators are a safety device that keeps the door from immediately unlocking if
power is lost while the machine is operating. They are mounted under the door locking solenoid.
Lock Thermoactuator
Control voltage is applied to the lock thermoactuator at the beginning of the cycle making it extend and
block the door locking solenoid. This keeps the door locked for approximately two minutes after a power
failure occurs. The lock thermoactuator does not delay the door opening at the end of a normal cycle.
Unlock Thermoactuator
To ensure that the lock thermoactuator has retracted by the end of the cycle, one minute prior to the end
of the cycle, the unlock thermoactuator is powered with control voltage making it extend and unblock the
door locking solenoid.
Loading Door Removal

B. Remove 3 bolts holding hinge retainer and set door o.
Loading Door Disassembly
A. Remove the loading door as outlined above.
B. Lay the door on a at surface with the glass down.
C. While holding down on the door glass, lift up on the door ring and roll back the lip of the
gasket with your ngers.
D. Work all the way around the gasket and the glass is out.
Loading Door Reassembly
A. Lay the door ring face down on a at surface.
B. Start the glass into one side of the door. gasket.
C. Use one hand underneath to push the gasket out and the other hand on the top pulling
the gasket in place.
D. The front lip of the door gasket should be checked for proper seating.
Loading Door Adjustment
The door can be adjusted by changing the number of shims behind the door hinge and the door
lock assem bly. The vertical t of the door to the tub can be altered by loosening the door hinge
bolts and raising or lowering the door before retightening. It is important for the door to be
centered on the tub front. By chalking the nose of the tub and closing the door to transfer that
line to the gasket, the centering can be evaluated. It is also important for door pressure to be
similar around the door perimeter. Door pressure can be evaluated by inserting a dollar bill in
several positions and tugging on it. See Parts Section for kit to increase door sealing
pressure.
Loading Door Hinge Removal
A. First remove loading door, front panel, and trim ring.
B. Remove 3 screws holding door hinge. Shims may be present between hinge and tub front.
The number may be increased or decreased to adjust right side door pressure.
NOTE: Door hinge mounting bolts penetrate tub front and require silicone sealer applied to holes
when reinstalling.
Control Panel Name Plate Decal
The name plate on washer front is adhesive backed.
Control Panel Name Plate Removal
The name plate may be removed by simply peeling it o.
Re-Installation of Name Plate
Step 1: Remove any remaining glue from the control panel.
Step 2: Before removing the paper backing from the name plate, check t to the control panel. The program
push buttons are the locating guides.
Step 3: Remove the paper backing from the right side of the name plate, position it on the panel and press
right end into place. Peel the backing from the left end and press into place.
Motor Relays
These relays are in the center of the control trough. The front relay is for intermediate spin. The middle
relay is for high speed extract. The back one is the run relay.
R1 Run Relay
The R1 Run Relay is a small relay that is mounted directly behind the R3 extract relay. The 120VAC coil on
the Run Relay is energized any time that the timer is in the run position and the door is locked. When en-
ergized, the Run Relay provides 24VDC to the reversing timer for wash and to the R2 intermediate extract
relay for spin.
R2 Spin Motor Relay (Intermediate Extract Relay)
The R2 Spin Motor Relay is the large relay that mounts in the center of the control trough. The i20VAC coil
on the R2 Relay is energized any time that the timer is in the spin position. 24VDC is provided from the
+24 terminal of the Variable Frequency Drive through the R1 Run Relay to the R2 Relay. When energized,
the R2 Relay provides 24VDC to terminals Ml2 & Ml3 on the Drive and the washer spins at intermediate
speed. The relay is removed by prying out on the mounting tab at the bottom of the relay with a straight
blade screw driver.
R3 Extract Relay (High Speed Extract Relay)
The R3 Extract Relay is a small relay that is mounted directly behind the large R2 spin motor relay. The
Main Timer provides 120VAC to the R3 Extract Relay coil. When this relay closes it provides 24VDC to the
Ll2 terminal on the Variable Frequency Drive. This relay combined with the R2 Spin Motor Relay powers all
3 terminals M11, Ml2 & Ml3 on the Variable Frequency Drive for high spin.
R4 High Water Level Relay
The R4 High Water Level Relay is a small relay that is mounted directly behind the R3 extract relay. The
Main Timer provides 120VAC to the R4 High Water Level Relay coil. The R4 Relay closes the circuit from
the pressure switch coming out of the high level contacts for the various high level baths in the cycle. It
also opens the circuit coming out of the low level contacts.
R5 Hot Rinse Relay
The R5 Hot Rinse Relay is a small relay that is mounted directly behind the R4 high water level relay. The
Main Timer provides 120VAC to the R5 Hot Rinse Relay coil. The R5 relay opens the circuit to the cold
water valve so that specic rinses are hot water only.
Program Timer
This timer is located on the left side of the control trough directly behind the reversing timer and is held
in place with two screws. It controls most machine functions. There are two drive motors on the program
timer. The one towards the front of the machine advances the timer at the beginning of the cycle. The
timer motor towards the rear drives the timer throughout the cycle. These two motors can be replaced in-
dividually. The program timer has a black knob that allows the timer to be manually turned to any portion
of the cycle for diagnostic purposes.
