This means that the child lock is activated. You can’t make any changes to programmes, temperature, speed or additional functions while the lock is active.
To deactivate the child lock, press the first and second additional function buttons simultaneously for three seconds while any programme is running. The lights on the buttons will flash while you do so.
You can also switch the programme selection knob to the On/Off position when no programme is running to deactivate the lock.
The procedure to activate/deactivate the child lock may vary depending on your model. If the procedures described above do not work, consult your user manual. If you’re having trouble finding your manual, download it here using your product’s model number.
