TEST PROGRAMME
To start the passive test programme :
1. Turn the programme selector to OFF
2. Hold the start button in and at the same time turn the programme selector to the first cycle
(40°C-55°C Normal). Wait until the light behind the start button begins to flash then
release the start button.
3. The four programme progress lights in the display panel will flash sequentially from left to
right. This indicates that the microprocessor is serviceable.
If there is a component failure, the light behind the start button will flash as indicated in the
table below to indicate the area to check.
Failure Failure
No.
Indication
Sensor failure F0 Start button lamp flashes ten times, one sec break, repeat
NTC failure F1 Start button lamp flashes once, one sec break, repeat
Water leakage F2 Start button lamp flashes twice, one sec break, repeat
Heating system F3 Start button lamp flashes three times, one sec break, repeat
Drain system F4 Start button lamp flashes four times, one sec break, repeat
Water inlet closed F6 Start button lamp flashes five times, one sec break, repeat
Flow meter F7 Start button lamp flashes seven times, one sec break, repeat
Water level F8 Start button lamp flashes eight times, one sec break, repeat
Continuous water fill F9 Start button lamp flashes nine times, one sec break, repeat
Rinse aid low - Red light on (This does not prevent the machine from operating)
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.
PROCEDURE FOR DIAGNOSTIC SERVICE TEST PROGRAMME
1. Start the passive test programme. (See Page 15).
If there is a defective component indicated (see Note 2), 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 multimeter. If
the component resistance is comparable with the data sheet, check cabling and
connections and examine the 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).

WHIRLPOOL CONSUMER SERVICES Model 6ADP2956 IXM
Page 15 of 19
5. After completion of any repair, run the test programme again to confirm repairs have
been effective.
NOTE 1 : The first step with test programme of new service control boards is without any
backrinsing steps. This is to prevent the machine from overflowing if it contains
any water at the start of the test. The second run of the test programme will
include the backrinsing steps.
NOTE 2 : Indicated failures F1 : NTC failure
F2 : Water leakage
F9 : Continuous water inlet
will cause the diagnostic programme to terminate, so these failures must be
repaired before it is possible to complete the test.
Once a wash programme has been started it cannot be altered but must be cancelled by
holding the start button for more than three 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.
PASSIVE TEST PROGRAMME
Passive test programme will indicate the mode of
Start failure. If there is no failure, the test programme
will result in the four programme progress lights in
the display panel flashing sequentially.
Starting the Passive Test Programme
Four programme 1. Turn the programme selector to the off ("O")
progress lights position
flash sequentially
2. Push and hold the start button while turning the
programme selector to the first cycle (40°C-55°C
Normal) until the start button light begins to flash.

FAULT DIAGNOSIS
F0 Sensor Failure
There is no indication to the user for this fault. If the sensor fails, the machine will
automatically default to the programme with the highest washability.
The fault will be indicated after 10 s to 30 s of the active test programme. The test
programme will terminate and the F0 fault code will be displayed.
The defects that result in the faults are :
No output or incorrect output from the sensor
Readings outside preset limits which could be caused by :
Defective electronic component in sensor
Opto-electronic component failure in sensor
Sensor cover is very discoloured from deposited soil
Connections between sensor and control board are broken.
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 25 minutes of heating operation.
- Element (HEW) defective
- Relay (RE2) on control board is defective
- NTC resistance fluctuation
- Water indicator (WI) defective (open-circuit)

ACTIVE TEST PROGRAMME
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 programme runs for
approximately 21 minutes or, if the heat cycle
is bypassed the test runs for approximately 4
minutes.
The active test programme runs to the point
of failure then stops. If there is no failure the
test programmes runs to the end.
To exit the test programme, press the
START
button for more than three seconds.
An empty rinse aid container will not
cause the test programme to stop, only
illuminate the red LED.
Zone Wash Valve "on" results in no water
spraying from the centre spray arm.
Zone Wash Valve "off" results in water
spraying from the centre spray arm.

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.
