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.
