Thanks for the speedy reply and I will release your funds. BUT, your reply did not fix my problem. The link you sent does not include 'MY' model number and that is not 'MY' knob. Maybe I was was not clear enough in my original question.
I think my knob is in two pieces. One piece is like the knob in the link. The other piece, is is flat piece with an arrow on it, under that knob. I do not remember if the two pieces used to be joined, but they are not now. The flat piece is what I have to push on very very hard to turn the dial to the required setting. When I pull out the knob to start the washer it pulls out but that flat piece stays flush.
