When press the start button a symbol with a lock sign on it cannot start the washing machine What is the logo mean????

SOURCE: machine won't wash because 'child lock' is on

Holding down the Start button for over 5 seconds turns the child lock on and off.

Eventually discovered that if the 'start' button is held down for a few seconds it unlocks the 'child lock'.

This might be Lid cover open protection. There is a small magnet at the edge of the lid cover, housed in some sort of a catch.
If the plastic housing cracked, the magnet might have dropped into the washing drum. To overcome this, place a magnet on the position where the plastic catch will contact the washer when the lid is close.

This is symbol shows that the child lock has been activated. This can only be turned on/off at the beginning or end of washing programme. To activate/de-activate this, just press and hold the Start/Pause button in for 5 seconds. The time settings will then re-appear and then you can proceed as normal

SOURCE: adding machine can't set date & time

My machine goes this way-
Hit time/date button.
then enter in date (ie) 11.16.2009--INCLUDE DECIMAL!!!
Then hit time/date button again,

I am still working on the time issue, I just cant seem to remeber, I know it is done off military time.
