This tests the sensor for proper operation as well as the value that the sensor is detecting.

To activate the test you must press and hold the Heavy and Start pads simultaneously.

When the test mode is activated, the digit display will show the turbidity value of the sensor.

This display will be a voltage reading in the decimal value.

Electronic Control and Keypad Assembly

The control on the dishwasher consists of the control board and the switch assembly. The switch is

installed into the top of the outer door panel, an elastomer keypad, used to actuate the switch, is

inserted into holes in the top of the outer door panel. The keypad assembly is attached to the control

board with a connecting ribbon. The keypad is held in place by a spacer that is clipped to the top of the

mount holding the control board. The control is mounted to a carrier panel that is attached to the outer

door panel. It is covered with a mylar blanket.

Control Board Plugs

Throughout this section references are made to the plug and pin location on the electronic control.

Figure 7 shows a picture of the electronic control pointing out plug numbers as well as pin and color of

the wire in each location.

Fill System

Two major components in the fill system are the inlet water valve and the pressure switch assembly.

Inlet Water Valve

The inlet valve is an electrically controlled shut-off valve that is used to allow water to enter the

dishwasher. The valve has a flow restrictor to regulate the water flow to 1.08 GPM at between 20 and

120 psi into the tub. The inlet valve is wired to the electronic control and is opened and closed by the

control. The inlet water valve is located on the front left frame leg just behind the lower front panel.
