Drive Belt Removal; Circuit Breaker; Control Mounting Trough; Coin Accumulator Transformer - Dexter Laundry WCN Series Manual

Drive Belt Removal

Turn the drive belt(s) off the basket pulley first and
then remove from the motor pulley.
Reverse this procedure for installation.
Note: The T-400 and T-600 have two belts that
should be replaced in pairs.

Circuit Breaker

The circuit breaker mounts to the rear channel. It
carries all of the controls in the machine but does
not include the motor. To reset the circuit breaker
just push in the button.

Control Mounting Trough

Remove top panel to access control trough. (See
Removing Top Panel) It sets on the right side of
the machine and holds many of the controls.

Coin Accumulator Transformer

This transformer that powers the coin accumulator
board is mounted on the right side of the control
trough. It steps control voltage down to a 12-volt
AC output. It is held in place with two screws.
Coin Accumulator Board
This board displays the number of coins to start
the washer, counts down the number of coins
as they are added and starts the program timer
when the preset coin amount is satisfied. With the
preset coin amount satisfied, the coin accumulator
closes a circuit sending control voltage.to the
timer on the orange with a white striped wire and
starts the washer. At the end of the cycle, the
timer closes the end of cycle cam providing control
voltage on the white with a yellow striped wire
to the coin accumulator board. This signal from
the timer resets the accumulator board so it is
ready to count coins and the display goes back to
the original amount of coins needed to start the
washer. 12-volt AC power for the coin accumulator
is supplied by the coin accumulator transformer
discussed above. The board is retained by three
nuts.
Reversing Timer
The reversing timer operates the wash and spin
relays and is mounted on the left side of the
control trough and retained with two screws. It
has three cam operated switches. Two switches
operate the Wash cycle by alternately engaging
the wash relays to tumble counter-clockwise for 19
seconds, stop for 3seconds, reverse direction and
tumble clockwise for j 9 seconds. The third switch
engages the spin relay for the high speed spin
portions of the cycle.

Drop Coin Acceptor
The drop style coin acceptor contains a coin switch that is actuated by each good coin that is ac-
cepted.
Removal
The coin acceptor is removed by loosening the two Torx T-10 machine screws on the right side and
by removing completely the two Torx T-10 machine screws on the left side (#T-10 Torx driver, Dexter
Pt. No. 8545-051-003). There are locking nuts on the back side that will have to be held. Needle-nose
pliers work well for this. Sliding the acceptor to the left will remove it from the slots in the front panel.
This gives access to the coin switch and acceptor for adjustments.
Coin Thickness Adjustment (see diagram)
On the right side of the acceptor there is a coin thickness "adjusting· screw "A" with a locking nut. To
allow for different thickness coins the screw can be turned in to accept thicker coins and turned out to
reject thicker coins. Start with a quarter of a turn on this screw and be sure to retighten the lock nut
after adjustment.
Coin Height Adjustment (see diagram)
On the left side of the acceptor is a coin height adjusting bar "B". This bar is adjusted by loosening
the two mounting screws and moving both ends of the bar up or down equal amounts. The bar should
be raised as high as possible while still accepting the correct coins. If it is raised up too high, the good
coins will be rejected.
Coin Switch Adjustment (see diagram)
The normally open coin switch "C" should click (close) soon after the coin hits the operator wire.
However, there must be enough travel to allow the switch to reset (open) once the coin has passed.
Adjustment should be made by bending the wire very close to its attachment point.
