CONTROL BOARD TEST POINTS
A pair of long, wire claw type probes are required to access the test points.
Checking voltages at the test points will determine the correct operation of the function push
buttons and the rotary switch.
Before
attaching test probes to the control board test points which are accessed via the control
board service window, disconnect the dishwasher from the supply. Short circuiting of any of the
electronic components will cause the control board to fail.
Test Points : T0 = Common
T2 = Analogue voltage
T1 = Analogue voltage
T3 = Digital signal
T0 T3 T2
T1
Control Board
A voltmeter with a high input impedance is required to measure the control board voltages.
The degree of agreement between the measured voltage and the nominated voltage will be
dependent on the accuracy of the voltmeter.
