Product review (5 stars): F35 Gone!!!  Me too
I was also getting the SUD/F35 code.  I read over these reviews, ordered the part and - with the advice from the other reviewers about removing the extra prong - put in the new part and the machine is working again......

I was not expecting the part to be so tiny and light, but it did the trick!

Just for the record, this repair was done in October 2012 - I purchased the machine in April 2008.
