So I think I found the correct location! However, I have turned the attached images, both ways and still no water enters the washing machine. Water works find everywhere else! I've just turned them that way to test, I understand that shouldn't work? They were in the other position before taking this photo. That other tap is in our airing cupboard. The little blue tap is what I presume the one to the washing machine, as the washing machine is located on the left outside of the picture.
