This is the procedure for a WMD960, expect it will be the same for the 962.
Turn on the machine with the door open using the on/off button
Press and hold the childlock,temperature and spin buttons at the same time for approx 5 seconds. The sceen will flash.
Scrollup/down using the temperature or spin buttons until the required language is seen in the display.
Press the child lock button to save the new setting.
I have just tried this procedure myself and it worked fine.
