Run the dishwasher through a test mode
Make sure the appliance is empty of water before running Diagnostics as it does not pump out before starting to fill and therefore you could overfill the appliance.
Open the door and set the program to the first program. (Normally rinse).
Turn the power off.
Press and hold the start button and while holding turn the power on.
After a little while the start button will flash, release the button.
Press the start button once and close the dishwasher door.
The machine will now run through a diagnostic routine.
Should take about 20 mins.
The machine will stop during diagnostics if an error is found and will display the error code. If no error is found it will complete the diagnostics and end the programme.
To exit diagnostics at any time just press and hold the start button till the programme is cancelled
