Troubleshooting Procedures

!WARNING

To avoid risk of electrical shock, personal injury or death; disconnect power to washer before servicing, unless testing requires power.

Board Output Test

While in Service Mode, pressing the Spin

Speed key will begin the Board Output Test.

This test turns ‘ON’ a specified output after a key press. Pressing the Spin Speed key again

cancels the test. Only one output can be ‘ON’ at any time. All outputs will be turned ‘OFF’ after five (5) minutes of inactivity.

When the Rotary Cycle Selector knob is set to “Super Wash” and the Rotary Cycle Selector knob is pressed, the main relay will be toggled (either from ‘ON’ to ‘OFF’ or from ‘OFF’ to ‘ON’).

When the Rotary Cycle Selector knob is set to “Normal” and the Rotary Cycle Selector knob is pressed, the hot water valve will be turned ‘ON’. This output will remain ‘ON’ until the Rotary Cycle Selector knob is pressed again to turn ‘OFF’ the output. The control will not allow the machine to fill past the High water level.

When the Rotary Cycle Selector knob is set to “Wrinkle Control” and the Rotary Cycle Selector knob is pressed, the cold water valve will be turned ‘ON’. This output will remain ‘ON’ until the Rotary Cycle Selector knob is pressed again to turn ‘OFF’ the output. The control will not allow the machine to fill past the High water level.

When the Rotary Cycle Selector knob is set to

Delicates” and the Rotary Cycle Selector knob is pressed, the bleach valve will be turned ‘ON’. This output will remain ‘ON’ until the Rotary Cycle Selector knob is pressed again to turn ‘OFF’ the output. The control will not allow the machine to fill past the High water level.

When the Rotary Cycle Selector knob is set to “Hand Wash” and the Rotary Cycle Selector knob is pressed, the pre wash valve will be turned ‘ON'. This output will remain ‘ON’ until the Rotary Cycle Selector knob is pressed again to turn ‘OFF’ the output. The control will not allow the machine to fill past the High water level.

When the Rotary Cycle Selector knob is set to “Quick Wash” and the Rotary Cycle Selector is pressed, the drain pump will be turned ‘ON’. This output will remain ‘ON’ until the Rotary Cycle Selector knob is pressed again to turn ‘OFF’ the output.

Pressing the Delay key will turn ‘ON’ the motor and the Delay LED. This output and the LED will remain ‘ON’ until the Delay key is pressed again to turn ‘OFF’ the output. When activated, the machine will tumble for 5 seconds in the CW direction, pause for 2 seconds, tumble in the CCW direction for 5 seconds, pause for 2 seconds; repeating this pattern until Delay key is pressed again to turn ‘OFF’ the tumbling.

Note: All tumble speeds are assumed to be 45 rpm.

Pressing the Chime key will unlock the door and turn ‘ON’ all the LED’s above the Chime key. This output will attempt to unlock one time, if safe to do so.

Pressing the Wash / Rinse Temp key will lock the door and all the Wash / Rinse Temp LED’s will turn ‘ON’. Pressing the Chime key will unlock the door and the all the Chime LED’s will turn ‘ON’.

When the Rotary Cycle Selector knob is set to “Whites” and the Rotary Cycle Selector knob is pressed, the bleach valve and the cold water valve will be turned ‘ON'

to check the fabric softener fill. This output will remain ‘ON’ until the Rotary Cycle Selector knob is pressed again to turn ‘OFF’ the output. The control will not allow the machine to fill past the High water level.

Pressing the Rinse & Spin key will turn ‘ON’ the heater if the water level is above the Heater Safety Level. If the water level is below the Heater Safety Level, a warning beep will be given and the heater will not be turned ‘ON’. The heater output will remain ‘ON’ until the “Rinse & Spin” key is pressed again to turn ‘OFF’ the output.

While performing the Board Output Test in Service Mode, follow this quick reference chart to check respective function.
