Had the same problems with my 9209, in both cases due to the poor quality of the spring activated switches at the back.
If the spring has come adift because one of the platic lugs has broken off, you can hold it in place with a small zip tie. Fixed mine like this a couple of years ago and its still working.
Recently the spring on the left hand switch broke. I made a new one from a suitable paperclip, using the old one as a pattern. It will last for a while until it bends out of shape. Will give me enough time to source a new toaster, I'm going to try a Buffalo compact - they are made for the catering industry so hopefully more robust and are about the same price.
