PROCEDURE FOR DIAGNOSTIC SERVICE TEST PROGRAM
1. Start the passive test program. (See Page 14).
If there is a defective component indicated, open the plinth and take out the control
board (CB).
2. Check the component.
Unplug the indicated component from the control board and check with a multi-meter.
If resistance is comparable with the data sheet check cabling and connections and
examine component.
3. Check control board.
Dishwasher components are controlled via electronic devices. As a result, when
checking component control board output voltages, the component connector must be
connected to the control board to load the electronic device.
4. If the dishwasher appears totally dead, perform test point tests. (See Page 19).
5. After completion of any repair, run the test program again to confirm repairs have
been effective.
NOTE 1 : The first step with test the program of the new service control boards is without
backrinsing. Therefore if the machine contains any water at the start of the test
there is a risk of overflow.
NOTE 2 : Indicated failures F1 : NTC failure
F2 : Water leakage
F9 : Continuous water inlet
will cause the diagnostic program to terminate, so these failures must be
repaired before it is possible to continue with the test.
Once a wash program has been started it cannot be altered but must be cancelled by holding
the start button for more than 3 seconds.
As the components are controlled by electronic devices, meaningful output voltage
measurements from the control board can only be made with the component connected. Do
not attempt to measure open circuit voltage output from the control board.

NOTE: The machine will not store Fault Code F6 located during normal operation, only
during the active test. Therefore the active test MUST be run for the
diagnostics to locate this fault. All Other Fault codes located during normal
operation are stored by the machine and will be displayed by the passive test.
PASSIVE TEST PROGRAM
Passive test program will indicate the mode of
Start failure. If there is no failure, the test program
will result in PS1 to PS4 flashing sequentially.

FAULT DIAGNOSIS
F1 NTC (Negative Temperature Co-efficient of Resistance) Device
- Temperature is outside normal range -3°C to +85°C
- Temperature inside the wash chamber is over +85°C
- The device is either open circuit or short circuit.
F2 Water Leakage
Water is in drip tray
- Float switch (LS6) operates, closes the water inlet valve and turns on the drain
pump until the water Indicator (WI) reports empty.
F3 Heating System Defective
Indicated after approximately 11 minutes of heating operation.
- Element (HEW) defective
- Relay (RE2) on control board is defective
- NTC resistance fluctuation
- Water indicator (WI) defective (open-circuit)
- Spray pump is not working
F4 Draining Failure
Drain pump energised and after four minutes Water Indicator (WI) still detects water.
- Drain pump (DPM) defective
- Drain hose blocked
- Control board defective
- Water Indicator defective (Pressure switch contacts remain closed)
F5 Spray Arm Blocked. (Fault does not cause dishwasher to stop)
SAB sensor sends less than 10 pulses/minute.
- SAB sensor defective
- Spray arm blocked or not located correctly
- Spray pump motor inefficient (insufficient water flow through pump.
F6 Water Control Cock Closed
Water valve (WV1) is energised but flow meter (FM) sends no impulses to CPU (less

ACTIVE TEST PROGRAM
Start the active test procedure by first running the passive test then press the start button for
less than three seconds.
Notes :
When the machine detects a fault during
normal operation the start light will begin to
flash and the cycle may or may not stop.
When the control knob is turned to zero the
fault is stored (except Fault Code F6) and
the fault code will be displayed when the
passive test is run. For the diagnostics to
locate fault code F6, the active test
procedure MUST be followed.
The active test programs runs for
approximately 21 minutes or, if the heat cycle
is bypassed the test runs for approximately 3
minutes and 45 seconds.
The active test program runs to the point of
failure then stops. If there is no failure the
test programs runs to the end.
The failure position is indicated by the
flashing START LED extinguishing.
To exit the test program, press the START
button for more than three seconds.
An empty rinse aid container will not
cause the test program to stop, only
illuminate the red LED.

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.
