Introduction

The “B” electronic control is composed of the

electronic control unit and the control fuse board with

wiring harness. Only an authorized person should look

inside the machine. First TURN OFF POWER, open

lid and remove any cover present. Make sure door lock

circuit has fully discharged. The door unlock capacitor

can retain high electrical charge, even when the

machine’s electrical inputs are disconnected, until it

has discharged. Some machines are equipped with an

“amber” indicator light facing upward in the control

compartment. If this is on, wait until it goes off

(indicating when high voltage in the door lock circuit

has discharged).

Electronic Control Unit

This portion of the control contains the “intelligence” –

the micro-controller and the miscellaneous components

on the printed circuit (PC) board. The board has a

metal cover, which MUST be in place at all times

during machine operation. Operation of the machine

without this cover installed will void the warranty.

The control unit monitors and responds to input, gives

information about the status of the washer and

monitors and responds to inputs from the user

interface (keypad). The control provides signals to the

control output unit, which in turn operates the

components that control the machine functions. This is

located behind the machine control panel.
