Open the cover plate of the washing machine.
Take the combination support plate - electronic timer out of the machine. See also paragraph 9.4.
The Flash Memory with the implemented software is the only IC on the logic board that can be
removed.
Take the Flash Memory out of the IC-holder and replace it by a new one.
Make sure that you put the new chip at the right position. See picture.
Put the combination support plate - electronic timer back at it's original position.
Reconnect all the connectors and put the hose back on the level sensor. (fastener!)
Close the cover plate of the washing machine.
Switch on the main power.
The display should illuminate.
If the software is compatible with the previous software: the new software can be used without re-
initialization.
You have to clear all the Diagnostic error messages in the Service-menu, if you want to make a
correct inspection of the functioning of the new installed software.
If the software is not 100% compatible with the previous software version:
The new software will generate a diagnostic message 35. When fault message 35 occurs you
have to reset the settings of the configuration and initialization menu.
This can be easily done by Selecting Reset Factory Settings in the Configuration Menu.
This is explained in Chapter 3 : Basic Description of Controls.
Go through the Menu items of the Configuration and Initialization Menu one by one to ensure
that all the settings do correspond with the ones you prefer.
All the Custom Settings will be lost.
Switch the power Off for 5 seconds, then turn power back on. When the reset has been executed
properly, Err 35 will not appear on the display anymore.
Now the Graphic Control Washing machine computer is ready to start a new cycle.
ATTENTION !!!
