@Laura Sweeney: I'm sorry to hear that you weren't able to locate the parts you need. As an alternative approach, and to ensure that the seals are fitted within the dishwashers specifications, I recommend checking out the link below to arrange for an engineer to inspect the appliance. If you're within warranty then this will be free of charge, however if not then the engineer will be able to source the necessary parts for you, and provide a quotation for the parts/service.
