Control Mounting Trough; Main Data Communication Cable; Circuit Breaker/Fuse; Main Control Printed Circuit Board - Dexter Laundry WN0675 Parts And Service Manual

Control Mounting Trough

Remove top panel to access control trough. It sets on the right side of the machine and holds the control
PCB's, transformers, and pressure switch.

Main Data Communication Cable

Goes between front PCB board and Variable Frequency Drive unit mounted center rear of machine. It
has telephone type connectors at each end and is inserted at Controller PCB and the Variable Frequency
Drive.

Circuit Breaker/Fuse

The fuse (optional 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. If you have a fuse then remove
fuseholder and fuse and replace with a 1 1/2 amp fast blow type fuse.

Main Control Printed Circuit Board

Fuse Location
Please be sure to be grounded to machine before removal of this board
from machine. PC board mounted vertically behind front control panel.
Remove hold down nuts in 4 corners and 1 at bottom center.

Controls Transformer

This transformer is mounted at the back of the control trough and steps a range of 208 to 240 volts down
to 120VAC and 24VAC. There are two terminals on the controls transformer for incoming power. One
terminal tap is marked for 208 volts use this tap for measured voltage of 200 volts - 215 volts and the other
tap is marked 230 volts for 216 volts - 240 volts. NOTE: All washers have a controls transformer. Always
check the incoming voltage and use the appropriate transformer terminal when installing ALL washers.

Main Relay Printed Circuit Board

Please be sure to be grounded to machine before removal of this board. PCB mounting horizontal in
control trough towards front of machine. Remove 4 mounting nuts.
LED Printed Circuit Board Temperature & Start Display/Push-Button
The selector switch is mounted in the right hand side of the control panel and is held in place with five
nuts. It allows the selection of hot, warm, or cold water temperatures. NOTE: Do not over tighten on
reinstallation as the switch can be damaged, staying pushed in and will cause erratic displays.

Pressure Switch

The pressure switch sets the water level in the washer. As the water level rises, it compresses the air in
the pressure switch hose. When the washer reaches the desired water level, the compressed air in the
pressure switch hose opens the contacts in the switch, shutting off the water. When at the empty level, the
pressure switch contacts are closed allowing the machine to either spin or fill with water.
