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.
