Section 2:
Machine
Installation
& Operating
Instructions
Installation & Operation
All washers must be installed in accordance with all local, state and national building, electrical, and
plumbing codes in effect 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 insure a stable unit, eliminating vibration. All installations must be made on sound concrete oors.
See mounting dimensions for each model being installed.
Mounting
A concrete pad or steel base which elevates the machine 4 to 6 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. Dexter highly recommends the use of a dry expansion
grout mix.
Proper Machine Grout Installation
Grout should be installed between base (if used) and concrete oor on all side rails and crossmembers. If
using a base you should grout between base top and machine frame and all side rails and crossmembers.
Mounting Holes
See mounting dimensions for the machine model you are installing in previous section. They also show
a typical concrete pad arrangement. It is highly recommended that you use all mounting holes supplied
with each model. Note: Mounting bolts should be checked frequently to insure 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. Please note: Machine grouting is highly recommended as
grouting insures stability and longevity.
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 off valves or faucets for
inlet hose connections must be provided, maintaining 30 to 120 p.s.i. water ow pressure. Maximum water
temperature is 180 degrees.
Drain
The drain outlet tube at the rear of the machine is 3” in outside diameter on models T-400, T-600, T-900,
T-1200. A exible hose (# 9242-417-003) is available to extend the drain system for these models.
A drain outlet tube at the rear of the machine is 2 1/4” outside diameter on a T-300. model. A exible
hose ( #9242-417-001) is available to extend the drain system for these models. 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 off before putting the machine into service.
Electrical
Dexter single/three-phase 208-240VAC 60 Hz washing machines are intended to be permanently installed
appliances. No power cord is provided. The machine should be connected to an individual branch circuit
not shared by lighting or other equipment. The connection should be sheathed in liquid tight exible
conduit, or equivalent, with conductors of the proper size and insulation. A qualied technician should
make such connections in accordance with the wiring diagram.
T-300 WCAD18KCS-10 model (1 phase 120 volts) washers are equipped with an electrical cord with a
3 prong grounded plug. A U.L. approved receptacle, which has been properly grounded in accordance
with local electrical codes must be used with the machine. Each unit should be connected to an individual
branch circuit not shared by lighting or other equipment. Conductors of the proper size and insulation (sug-
gested size below) should be used.

Fault# Description Customer Action
F13 The variable frequency drive
(VFD) and the washer computer
are not communicating.
Check the data communication cable between the washer
computer and the variable frequency drive (VFD).
Step 1: Make sure the cable did not become unplugged during
operation.
Step 2: Make sure that the cable is not being pulled sideways
at either the washer controller, or the VFD, plug end. If
both ends of the communications cable are plugged in the
washer computer and VFD and there is no tension on the
communications cable pulling it from side to side, then replace
the cable.\
Step 3: Inspect both female connection points at PCB
controller and at VFD. These may need replacement if they
cannot be reset.
F14 Over-current on the drive or
motor. Step 1: Check to make sure the washer cylinder turns freely
by hand. If it turns freely, continue to step 2. If it does not,
remove the belt and see if the motor turns freely by hand.
If the motor turns freely, then check for obstructions in the
cylinder or check the bearings. If the motor does not turn
freely, replace the motor.
Step 2: Check the motor wires for a short circuit between
leads. If there are motor leads that have conductors touching,
separate them and insulate them. If the wires are broken,
splice them together or replace the motor.
Step 3: Check braking resistors to see if they measure the
correct resistance. If a resistor does not measure the proper
value, replace it.
F15 The variable frequency drive
(VFD) senses that the internal
voltage is too high. The source
of the problem can originate
from two different areas. Area
1: The input voltage can be too
high, or there may be a high
level of electrical noise. Area 2:
The motor can be generating
a voltage that is acting like an
input to the VFD output motor
terminals.
Step 1: Measure the supply voltage to the VFD on the L1, L2
(or N), and L3 (if connected to three phrase power). the supply
voltage should be from 187 to 264 VAC or 108 to 132 VAC for
a 120 VAC VFD. Also make sure the supply wires on L1, L2
(or N) and L3 (if connected to three phase power are securely
connected.
Step 2: Check the braking resistor connections at the VFD.
The terminal screws should be tight. Once of the braking
resistor wires should be connected to terminal B2.
Step 3: Measure each braking resistor separately to make
sure they are the correct resistance. (200 for 1 and 2 Hp VFD
and 160 for 3 Hp VFD).
Step 4: If you have a 240 VAC, high leg voltage supply, try
disconnecting the high leg. If this cures the problem, either
leave the high leg disconnected, connect a transient voltage
surge suppressor (with some form of ltering) at the voltage
supply panel, connect a line choke on the high leg or install a
VFD lter.

F16 The temperature sensor inside
of the variable frequency
drive detects that the internal
temperature is too high.
Step 1: Make sure the cooling ns on the VFD heatsink and
the ventilation louvers on the VFD cooling fan cover are clean.
Step 2: Start a washer cycle and make sure the VFD cooling
fan operates after the cylinder starts turning.
F17 Overload of the drive or motor (Check drive fault code before powering down). Check the
washer motor to ensure it turns freely. Check the wiring for
loose connections to the drive and motor. Measure the braking
resistor values. Check for damaged motor wires. Check V-Belt
tension and adjust to 1” deection at center. Check braking
resistors.
F18 Ground Fault to the drive Check VFD fault code before turning off power. Check the
wiring connections to the drive and motor. Check the ground
wiring of the drive, motor and incoming connection to ensure a
proper ground is present. Check for damaged motor wires.
F19 Low Voltage to the drive Check VFD fault code before turning off power. Turn the
power off to the washer. Check the wiring connections to the
drive and motor. If no problem is observed, turn on power to
the washer and test. (See Note) Measure the incoming line
voltage.
F20 Internal drive error Check VFD fault code before turning off power. Turn the
power off to the washer. Wait one minute. Turn the power
on to the washer. If problem reappears, contact your Dexter
representative.
F21 Data error on communications
between the controller and
drive Internal drive error #
32. This error also has CEXX
errors associated with it that are
presented on the drive display.
The CE errors are communications errors. Data Cable noise
can cause the majority of these errors.Check VFD fault code
before turning off power. Check the data cable between the
controller and the drive. Replace data cable if it appears
damaged and fault appears again. Please note that this fault
will occur if you turned main power off and on to quickly. (See
Note below)
Warning codes F22 - F28: These codes indicate that a component (VFD, relay PCB, in-

Normal operation of the VFD: VFD display shows operating frequency rst very quickly then changes
to F0.0 at time power is returned. This will stay displayed until the VFD receives a command from main
control PCB. (Pushing start button) A CE-10 fault will display at drive if improper communication between
PCB and VFD has occurred.
Note: Resetting a fault code on front of washer: Turn the power off to machine (machine will need to
remain off for up to three minutes ).
SOFT RESET : is accomplished by pushing the white button located on the Main controller PCB board and
simultaneously turning power on to machine. This will reset main controller to factory default settings.
Please record any modied information that has been inserted in memory before attempting to Soft Reset

Electrical Path Circuit Schematics
Start Circuit
Power travels into the machine on L1 & L2 & (L3, if 3 phase used). L1 and L2 provide 208- 240VAC to
the controls transformer which steps the voltage down to 120VAC for the controls. (The L1 connection
at the controls transformer must be checked at start-up to coincide with machine operating voltage) The
120VAC travels out from the transformer on either [X-1 red wire directly to the 1.5 amp fuse] or [X-1 black/
red wire to TB-4 and then through the red wire to the 1.5 amp fuse]. The controls transformer also cre-
ates a neutral on the X-2 black/blue wire that connects to TB-1. From the fuse holder, 120VAC travels on
the red wire to the #6 terminal on the terminal strip and then through the black wire to another step-down
transformer. From the terminal strip the blue wire will provide the neutral for solenoid, thermoactuators and
all valves. The white wire provides the neutral from the terminal to the step down transformer.
120VAC is stepped down to 2.3VAC (blue wires), 24VAC (red wires), and a yellow center tap wire to the
P-7 power connection on the main controller PCB . With the main control PCB now powered, 5VDC will
be present between the (2) yellow wires and also the (2) brown wires for the coin switches. Both pairs will
now be ready to count coins through the P-2 connection at the control PCB. 26.8 VAC goes out on the
black wire of the P-4 connection from the main control PCB to the S5 door closed switch which mounted
on the hinge side of masking ring. Closing the door will engage the door closed switches, sending the volt-
age to the red wire on the S1 door latched switch. Turning the door handle to the vertical latched position
closes the S1 door latched switch, returning the voltage to the main control PCB on the white/red wire at
the P-4 connection. 26.8VAC is now present at the S2 and S3 door locked switches.
26.8VDC is also at the black and white wires between P-21 at the main control PCB and the P-20 of the
relay PCB. This voltage signals the relay PCB that the door is closed and latched making 120VAC avail-
able to the relays controlling the door lock solenoid, drain valve and water valves. A continuous 5VDC
is sent on the red wire from the P-1 connector on the main control PCB, through the (normally closed)
emergency stop button switch and returns on the second red wire back to the P-1 connector. Payment is
added and the display counts down on the main control PCB display until the vend price is satised. The
display will change to read PUSH and the green light over the start button will ash. Pressing the start but-
ton on the front of the main control PCB signals the relay PCB to lock the door and 120VAC will go to the
door lock solenoid on the white/red wire from the P17 connector of the relay PCB. The door lock solenoid
engages and pulls up on the door locking rod, locking the door and closing the S2 and S3 door locking
switches.
The S2 locking switch is a backup to the S1 latching switch so that once the cycle starts the S1 isn’t criti-
cal. The S3 locking switch provides 26.8VDC on the orange wire back to P4 connector at the main control
PCB and the P15 connector at the relay PCB. This signals that the loading door is closed,locked and safe
to continue wash operations. This activates the P-13 and P-14 yellow enable wires to the inverter drive
to allow motion. If there is no signal on P-15 (orange wire) their will be no motion of the tub. S1, S2, S3
and S5 door switches are now closed . The green On LED and the door lock solenoid (discussed in start
circuit) will remain on throughout the cycle.
Fill Circuit-Warm
The relay PCB supplies 120VAC to the brown/yellow wire from P-17 to the drain valve which closes the
valve. The lock thermoactuator also receives 120VAC on orange/blue from P17 of the relay PCB. This
device prevents the door lock solenoid from dropping out and unlocking during the cycle in the event of a
power loss. The 120VAC will cycle on and off keeping the lock thermoactuator engaged until 70 seconds
before the end of the cycle. The main control PCB sends data commands to the VFD through the data
cable connected at P-6. These commands control the wash basket which will tumble one direction for 12
seconds, pause, and then reverse direction for 12 seconds.

The prewash or wash LED will illuminate at this time, powered through the white wires from the P-3 con-
nection of the main control PCB to the LED printed circuit board. Using the factory preset cycle as an
example: The washer lls the tub through the back of the machine with either one or both the C1 cold and
H1 hot water valves. From the P19 connection of main relay PCB, 120VAC is sent out on the white/brown
wire to the C1 cold water ll valve and the red/yellow wire to the H1 hot water ll valve depending on the
temperature selected. After a 90 second delay from the beginning of the wash cycle bath only, the deter-
gent dispenser ushes the detergent into the tub for 20 seconds. This is accomplished when 120VAC trav-
els through the red/orange wire to the H2 hot water valve solenoid. During the machine ll, a 5VDC signal
is sent on the red wire from the P5 connection of the main control PCB to the pressure switch contact and
returns on the yellow and orange wires to the P5 connection of the main control PCB. When the water
level in the basket reaches the preset level pressure, the switch moves the switch contacts to the full or
open position. This causes the main control PCB to signal the relay PCB to shut off the water valve coils.
Wash Circuit
Once the machine has achieved it’s water level, the wash basket will continue to tumble one direction for
12 seconds, pause, and then reverse direction for 12 seconds. The time on the front display will count
down as the bath progresses. The time of the bath is programmable up 15 minutes per bath. Note: When
programming cycles, the wash bath must be programmed for 3 minutes or more.
Drain
When the program bath time ends the main control PCB signals the relay PCB to remove 120 VAC power
from brown/yellow wire at P17 going to the drain valve. The normally-open, spring-loaded drain valve
opens allowing water to exit the machine. This resets the pressure switch back to an empty level and
restores the 5VDC connection through the pressure switch from the red wires to the orange and yellow
wires.
Rinse 1 & 2
For Rinse 1 & 2, the rinse LED will illuminate, the drain valve will receive 120VAC and close. The basket
will ll and tumble the same as the wash bath for the programmed time. The rinse water temperatures are
programmable and factory default is cold.
Final Rinse Circuit
The nal rinse LED will illuminate, the drain valve will receive 120VAC and close. The basket will ll and
tumble the same as the previous baths for the programmed time. The nal rinse water temperatures are
programmable. Note: When programming cycles, the nal rinse bath must be programmed and cannot
be set for less than 3 minutes. Also at the beginning of the nal rinse bath, the main control PCB will signal
the relay PCB to send 120V to the P-19 connector on the white/blue wire to the C2 cold water valve for 20
seconds to ush the fabric softener dispenser.
Spin Circuit
The spin LED will illuminate and the main control PCB sends a signal to the variable frequency drive via
the data cable at P6 to VFD RJ-11. The rotation as viewed from front during spin will be counter-clockwise.
(The 18lb washers will extract in a clockwise direction) The time of the spin cycle can be programmed.
Note: The nal spin must be programmed into the nal rinse bath and must be programmed for 1 minute
or more.

Unlock Thermoactuator and Shake Out Circuit
70 seconds before the end of the cycle the main control PCB signals the relay PCB to remove 120VAC
from the orange/blue wire at the P-17 connector on the lock thermoactuator. This allows the lock ther-
moactuator time to cool and retract by the end of the cycle. To insure that the lock thermoactuator has
retracted by the end of the cycle, 1 minute prior the end of the cycle, the unlock thermoactuator is powered
with 120VAC through the orange/red wire from the P-17 connector of relay PCB. The unlock thermoactua-
tor moves the complete bracket assembly away from the door lock solenoid allowing it to drop at the end
of the cycle. The basket will come to a stop from spin speed with the assistance of dynamic braking resis-
tors wired to the variable frequency drive. (See wiring diagrams for quantities and resistor ohm values).
The washer will then tumble for 45 seconds to let the clothes shake loose from the basket and then stop.
End of Cycle and Door Open Circuit
Once the machine stopped, 3 things occur: 1. The beeper will signal for 5 seconds letting the user know
that it is the end of the cycle. 2. The main control PCB signals the relay PCB to remove power from the
white/red wire at P-17 which allows the door lock solenoid to unlock. 3. The main control PCB resets when
the S1,S2,S3,S5 switches open and door is opened. The machine is now ready to accept coins again.
