Can you check the model number please?
I'm not finding this in my technical library.
The number should be on a label in the door recess.
Sorry, that's not a model number.
Normally it's the WM or an F beginning.
However, there's no WM1122230FB listed.
Look closely at the facia panel on your machine.
Bewteen 2 buttons there will be a padlock or child's head symbol.
Press and hold the two buttons until the CL goes off.
CL indicates child lock is activated.
You need to deactivate it.
Hope this helps
