Can you post the model number please. If you are able to open the door the number will be on a sticker on the inside there and starts E-nr
Thats great. Give me a few minutes to look this up and i will relpy in a few minutes.
The key signs means the child lock is turned on.
All you need to do to turn this off is with the washer turned on press and hold the start button for several seconds and that will turn the lock off and allow you to use the washer as normal from there.
Try that and see what happens and let me know.
Nice one. Glad that sorted it and thanks for letting me know.
If you could remember to rate the answer that would be great.
