Had the same problem.
Turn on the machine. Hold the 'Program/Clear' button down until it beeps.
Release button.
You should now be able to push the 'Program' button and select programs. If this part is working now, THEN hold down both 'Program' button and 'Start' button together for about 5 seconds (you will probably see 'CL' in the LCD screen).
A 'beep' will signal child lock is now turned off.
